28. Which statement best explains why cellular respiration in plants and
other organisms is dependent on photosynthesis?
Photosynthesis is one of the final steps in cellular respiration,
Photosynthesis absorbs materials that are catalyzed during cellular respiration.
Photosynthesis absorbs excess energy produced by cellular respiration.
Photosynthesis provides the materials that fuel cellular respiration.
Answer: Photosynthesis provides the materials that fuel cellular respiration.
Explanation:
Photosynthesis, the process through which green plants convert light to chemical energy. The energy that is gotten from sunlight by green plants, some protistans, and bacteria is used to produce sugar which is then converted to ATP by cellular respiration which is regarded to as the fuel that living things use.
Therefore, the statement that best explains why cellular respiration in plants and other organisms is dependent on photosynthesis is that photosynthesis provides the materials that fuel cellular respiration.
Answer:
Photosynthesis provides the materials that fuel cellular respiration.

The toxin produced by the intestinal bacterium Vibrio cholerae induces excessive diarrhea by stimulating the excretion of NaCl and large amounts of water into the intestine. The mechanism by which cholera toxin acts is ADP ribosylation of: a. the GTP-bound form of Gai, locking it in the active conformation. b. the GDP-bound form of Gas, locking it in the inactive conformation. c. the GTP-bound form of Gas, locking it in the active conformation. d. Gaq, inhibiting its GTPase activity. e. Gai, decreasing its affinity for GDP.
Answer:
c. the GTP-bound form of Gas, locking it in the active conformation.
Explanation:
The reason is that the toxin created by the enteric intestinal bacterium Vibro cholerae triggers an exorbitant amount of diarrhea by inducing the excretion of NaCl and enormous amounts of water into the bowel. The mechanism by that epidemic cholera toxin acts is ADP ribosylation of the Gs alpha monetary unit. This implies that G[tex]\alpha[/tex]s macromolecule protein exploits NAD, therefore protecting it within the active conformation.
What two substances among four major types of organic compounds are made by living things? A.carbohydrates
B.water
C.proteins
D.potassium
Answer:
The answer is "Carbohydrate" and "Protein"
Explanation:
A solid eating regimen incorporates protein and starches. Why? Since these mixes are two of the primary structure obstructs that make your body. You get these structure blocks from the food that you eat, and you utilize these structure squares to make the natural mixes important forever.
The principle substance parts of living beings are known as natural mixes. Natural mixes are atoms worked around the component carbon (C). Living things are comprised of exceptionally huge particles.
These huge particles are called macro-molecules since "macro" signifies large; they are made by more modest molecules holding together. Our body gets these more modest particles, the "building blocks" or monomers, of natural atoms from the food we eat.

(4pts) Drugs, medicines, and poisons often work by acting on endogenous proteins. They do this by looking similar to a signal molecule and binding to the endogenous protein. Look up these four examples to fill in this chart. Drug, medicine, or poison Looks similar to this endogenous molecule: Binds to this endogenous protein/receptor: Muscarine Acetylcholine muscarinic receptors Prozac Serotonin serotonin transporter protein Ketamine NMDA NMDA receptor Tamoxifen estrogen estrogen receptor
Answer:
Drug, medicine, or poison: Muscarine; Looks similar to this endogenous molecule: Acetylcholine; Binds to this endogenous protein/receptor: muscarinic receptors
Drug, medicine, or poison: Tamoxifen; Looks similar to this endogenous molecule: estrogen; Binds to this endogenous protein/receptor: estrogen receptor
Drug, medicine, or poison: Prozac; Looks similar to this endogenous molecule: Serotonin; Binds to this endogenous protein/receptor: serotonin transporter protein
Drug, medicine, or poison: Ketamine; Looks similar to this endogenous molecule: NMDA; Binds to this endogenous protein/receptor: NMDA receptor
Explanation:
Muscarine is a poisonous natural product found in certain mushrooms. It is similar to acetylcholine and competes with acetylcholine at its receptor binding sites.Signs of muscarine poisoning include salivation, lacrimation, vomiting, diarrhea, abdominal pain, bradycardia, etc.
Tamoxifen is a selective estrogen receptor modulator. It is similar to estrogen and acts by inhibiting the effects of estrogen in the breast tissue. It is used to prevent and treat breast cancer in men and women.
Prozac is an antidepressant which belongs to th class known as selective serotonin reuptake inhibitors. It looks similar to serotonin and inhibits its action by competing with serotonin for its binding site. It is used for the treatment of depression disorders.
Ketamine is an NMDA (N-Methyl-D-aspartate) receptor antagonist. NMDA receptor antagonists are a class of drugs that work by inhibiting the action of the NMDA receptor. They are commonly used as anesthetics for animals and humans to induce a state of anesthesia known as dissociative anesthesia.
The Hardy-Weinberg equilibrium is a theoretical model that predicts the frequency of different genotypes in a population that is not evolving. A scientist studying the population genetics of the rainbow fish finds that the Hardy-Weinberg model predicts that the frequencies of the three different genotypes for the albino gene in a given lake should be as follow: AA: 49%, Aa: 42%, and aa: 9%. However, the scientist obtained a sample of 320 individuals of this species and found that the numbers of individuals for the different genotypes are: AA: 180, Aa: 120, and aa: 20.
Complete question:
The Hardy-Weinberg equilibrium is a theoretical model that predicts the frequency of different genotypes in a population that is not evolving. A scientist studying the population genetics of the rainbow fish finds that the Hardy-Weinberg model predicts that the frequencies of the three different genotypes for the albino gene in a given lake should be as follow: AA: 49%, Aa: 42%, and aa: 9%. However, the scientist obtained a sample of 320 individuals of this species and found that the numbers of individuals for the different genotypes are: AA: 180, Aa: 120, and aa: 20. Use the appropriate statistical technique to test (use alpha = 0.05) whether the observed genotype frequencies are consistent with eh Hardy-Weinberg model. State your conclusion.
Answer:
There is enough evidence to reject the null hypothesis. The genotypes are not in equilibrium. The genotype frequencies are consistent with the Hardy-Weinberg model.
Explanation:
Expected Number of individuals with each genotype: Each genotype´s frequency multiplied by the total number of individuals in the sample.
AA= 0.49 x 320 = 156.8
Aa= 0.42 x 320 = 134.4
aa= 0.09 x 320 = 28.8
Observed Number of individuals with each genotype:
AA= 180
Aa= 120
aa= 20
Chi square= ∑ ((O-E)²/E)
∑ is the sum of the terms O are the Observed individualsE are the Expected individualsAA= (O-E)² /E
AA= (156.8 - 180) ² / 156.8
AA= 538.24/156.8
AA= 3.433
Aa= (O-E)² /E
Aa= (134.4-120)² / 134.4
Aa=207.36/134.4
Aa= 1.543
aa= (O-E)² /E
aa= (28.8-20)²/28.8
aa= 2.69
X² = ∑ ((O-E)²/E) = 3.433 + 1.543 + 2.69 = 7.666
Freedom degrees = genotypes - alleles = 3 - 2 = 1
Significance level, 5% = 0.05
p value less than 0.05
Table value/Critical value = 3.841
7.666 > 3.84 meaning that the difference between the observed individuals and the expected individuals in each chamber is statistically significant.
There is enough evidence to reject the null hypothesis. The genotypes are not in equilibrium.

Which of the following describes a way that decomposers are important to an ecosystem?
Answer:
Decomposers recycle essential nutrients back into an ecosystem.
Explanation:The decomposers are the small microorganisms which can be found in the soil habitat. These organisms obtain energy by break down of organic matter generated after the death of plants, animals and their residual matter. Through the process of decomposition the decomposers release nutrients such as nitrogen and carbon back to the environment. These nutrients are absorbed by the plants through soil. This way the nutrients are recycled in an ecosystem by decomposers.

In mouse, genes X, Y and Z are on chromosome 2. The map of genes X, Y and Z is:
X----------------Y-------------------------Z
20 m.u. 30 m.u.
You cross an individual with genotype XXYYZZ to an individual with genotype xxyyzz, and F1 progeny are collected. Assume interference between regions (X-Y and Y-Z) is 100%. When an F1 individual produces gametes, what proportion of its gametes would have xyz genotype?
a. 10%
b. 20%
c. 25%
d. 30%
e. 40%
f. 50%
g. 0%
h. None of these above
In F1 we will get 100% XxYyZz
each of these organism has two chromosomes that look like this
X..........20..........Y...............30...............Z
x..........20..........y...............30...............z
Those two chromosomes are homologous
we want a gamete that contains the second chromosome where crossing-over didn't occur. The distance between the genes of the chromosomes in map units is equal to the frequency of recombination in percentage. Therefore there is a 20% that x and y will recombine and a 30% chance that y and z will recombine. We want a chromosome that is not recombined.
The possible gametes are
XYZ XYz XyZ Xyz xYZ xYz xyZ xyz if the genes were on different chromosomes xyz would be 1/8 or 12,5%
Since there is a 20% that the genes x and y will recombine that means there is a 80% chance that they won't and since there is a 30% chance that the genes y and z will recombine that means there is a 70% chance that they won't.
80%*70%=56% chances that the genes won't recombine. But, there are two non-recombinant gametes:XYZ and xyz therefore the chances for xyz is 56/2=28%
In mouse, genes X, Y and Z are on chromosome 2. The map of genes X, Y and Z is: X----------------Y-------------------------Z, When an F1 individual produces gametes, we will get 100% gametes would have xyz genotype that is XxYyZz, it can be represented as
X..........20..........Y...............30...............Z
x..........20..........y...............30...............z
What is chromosome ?A chromosome can be observed as a thread-like structure present in the nucleus of cells such as plant, animal and human cells, composed of DNA (Deoxyribonucleic acid) molecule and histone proteins.
The three major components, DNA, proteins and RNA, the content of the DNA ranges from 30 to 40 % whereas proteins from 50 to 65%, and small amount of RNA ranges from 1 to 10%.
Two types of protein present such as histone and non-histones proteins, histone content is more (90% of total protein), whereas non-histone is content is less (around 10% of total protein).
The histone protein is basic, the DNA is acidic which can be neutralized; DNA is present in two forms such as Euchromatin and Heterochromatin.
20% that x and y will recombine and a 30% chance that y and z will recombine. We want a chromosome that is not recombined.
The possible gametes are XYZ XYz XyZ Xyz xYZ xYz xyZ xyz if the genes were on different chromosomes xyz would be 1/8 or 12,5%

Do you agree that wild species such as orangutans have the right to exist whether or not they are useful to humans? Explain.
Answer:
Because orangutans live in only a few places, and because they are so dependent upon trees, they are particularly susceptible to logging in these areas. Unfortunately, deforestation and other human activities, such as hunting, have placed the orangutan in danger of extinction.
Explanation:
Hope this helps ;)
Ape like organisms with red coloured hairs that are mammals and belong to the Hominidae family are called Orangutans. They are found in the rainforests and are 1.2 - 1.8 m in height.
To this open question, I don't agree with the statement.
The viewpoint can be explained as:
They have the right to exist even when they are not useful to humans as they play a vital role in the food chain and the ecosystem in which they reside.If Orangutans are withdrawn from the ecosystem then many plant species will be impacted or can vanish.Orangutan helps in seed dispersion and sustain a healthy and balanced condition of the ecosystem.The residents, trees and the ecosystem are interdependent for survival and hence, they cannot be removed.To learn more about Orangutans follow the link:

The reviewers suggested that you think more carefully about your hypothesis and experimental design. For a chemical to make a good cancer treatment, it is not enough that it harms cancer cells. The chemical needs to have a selective effect on cancer cells--that is, it needs to harm cancer cells much more than it harms normal (noncancerous) cells.
You decide to run a new experiment to test the hypothesis that the fungus chemical harms cancer cells selectively. In this controlled experiment, you will test both cancer cells and normal cells under identical conditions. What data would support this hypothesis?

Alleles can be described as 1. dominant 11. recessive III. codominant IV. partially dominant V. incompletely dominant O A. I, II, III, and V only OB. I and II only OC. I, II, and Ill only OD II, III, and V only
Answer:
A. I, II, III, and V only
Explanation:
In genetics, an allele refers to the specific form of a gene, which encodes traits. These alleles are usually in pairs in a diploid organism i.e. an organism with two sets of chromosomes. According to Gregor Mendel,
- An allele can either be DOMINANT when the allele masks the phenotypic expression of its allelic pair while the allele that is masked is said to be RECESSIVE.
- Two alleles can also be CO-DOMINANT when the two alleles are neither dominant or recessive over one another but are simultaneously expressed in that particular gene.
- Alleles can also be INCOMPLETELY DOMINANT when one allele is not completely dominant over the other, hence, forms a third intermediate phenotype when in combination with the second allele i.e. in an heterozygous state.
Based on this, an allele can be dominant (I), recessive (II), codominant (III), and incompletely dominant (V).
