Answer:
B. preservation of advantageous genetic mutations
Explanation:
The process of natural selection involves the preservation of advantageous genetic mutation in a given population.
Natural selection is one of the key factors that ensures the evolution of organisms.
Desired traits that are able to survive adverse conditions like disease, food shortage, natural disasters are favored by the process of natural selection. Traits that also undergo advantageous genetic mutation in order to get a competitive advantage is also accrued to natural selection.The kind of genes an organism possesses is dependent upon the __________

Ally wants to reduce the amount of carbon dioxide in her local area. What are two different things that Ally could do to reduce the amount of carbon dioxide in the atmosphere? Explain how each would reduce the amount of carbon.
Answer:
1, Planting trees
2. Actions that reduce carbon dioxide emission
Explanation:
Ally can reduce the amount of carbon dioxide in the atmosphere in two ways
1. By planting trees or reforestation
Trees generally act as a sink for carbon through photosynthesis. Hence, planting more trees means that more carbon dioxide in the atmosphere will become fixed into the trees leading to the reduction of the gas in the atmosphere.
2. Reducing emission
To further reduce the amount of carbon dioxide in the atmosphere, the rate of emission of the gas has to be reduced. Actions such as the burning of vegetation and fossil fuels need to be reduced because they increase the emission of carbon dioxide gas into the atmosphere. The actions can be substituted for less or no carbon dioxide emitting alternatives.
When less carbon dioxide is emitted into the atmosphere and more is being fixed into trees, the overall concentration of the gas in the atmosphere will reduce greatly with time.

The graph here shows a population of rabbits in an ecosystem that the rabbits are not allowed to enter or leave
A. The death rate is very high.
B. It has access to more resources than it needs
C. The population density is very high.
D. There is great competition for resources.
The statement that is most likely to be true of the rabbit population in an ecosystem at point A is it has access to more resources than it needs. Thus, the correct option is B.
What is an Ecosystem?An ecosystem may be defined as a place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.
The death rate of any population is high when this population crosses the limit of carrying capacity. And here, point D represents this scenario, so option A is incorrect.
Population density is the measurement of individuals of any species at a specific geographical location, so option C is also incorrect.
The competition for resources is significantly high when the population of any species almost reaches the carrying capacity. And here, point C represents this scenario, so option D is also incorrect.
Therefore, the statement that is most likely to be true of the rabbit population in an ecosystem at point A is it has access to more resources than it needs. Thus, the correct option is B.

Fossil evidence cannot reveal which of the following important information about animals that have lived in the past? A. Size and weight. B. Diet and behavior. C. Exact year of death. D. Environment
Answer:
i would say B
Explanation:
Fossils can tell us about the size depending on how large the bones are. The year of death could possibly be determined by the way the bones look maybe, same with the environment, showing what type of animal; it could be a type of fish. But I believe there is no way fossils could show the diet and behavior of the animal.

When people fall ill, their immune system fights the disease and tries to restore the person to good health. Which disease is known to attack the human immune system leaving the body susceptible to various kinds of infection?A. Chicken PoxB. PneumoniaC. TuberculosisD. AID
Answer:
D. Aids
Explanation:
Aids is one of the most deadliest diseases in the world. When you contract aids, it's designed to infect the cells that try to destroy it, it's a whole zombie apocalypse in your body and you don't even know it.
It attacks and weakens the immune system, and our immune system defends our bodies against infections, but HIV is extremely strong and it over powers the system, I'm not sure if there's an immune system strong enough to fight HIV or aids.
explain the two inheritance patterns of blood type
Answer:
The ABO blood type is inherited in an autosomal codominant fashion.
The Rh system of blood groups determines the gene that forms two alleles: dominant (D) and recessive (d).
Explanation:
The dominant allele determines the synthesis of antigen D, so people with this antigen are referred to as Rh +. The recessive allele is dysfunctional so no D antigen is produced and individuals are Rh-
The ABO blood group system determines a gene that has three alleles:
A, B, and O allele.
Alleles A and B are functional and determine the synthesis of certain antigens (agglutinogens A B) that are found on erythrocytes.
In this exercise we have to use the knowledge of blood to explain its inheritance factors, so we want to explain how:
So we know that blood types in addition to the types known as ABO, there is also the RH factor which is the biggest inheritance.
What are the 3 blood types?Type A blood has A antigens, B blood has B antigens, AB blood has both antigens, and type O has neither. Red blood cells also have another type of antigen called RhD, which is part of a family made up of 61 Rh type antigens. When the blood has RhD, it is type positive.
Our blood group is inherited from both parents. Just as we are given physical characteristics like skin color or hair, we also inherit blood type. Surprising as it may seem, blood group is not genetically determined at birth according to the contributions of both parents.

Are catabolic pathways endergonic or exergonic reactions? Compare the amount of free energy in the reactants to the amount of free energy in the products of a catabolic pathway.
Answer:
Catabolic reactions are exergonic.
Explanation:
Exothermic reactions are catabolic, that is, they catalyze molecules, disintegrate them to be able to release energy to the environment that surrounds them and that is how they release or yield to the environment.
A frameshift mutation will change a.Only one codon b.Only two codons c.All codons both before and after the point at which the mutation occuredd.All codons only after the point at which the mutation occured
Answer: d. All codons only after the point at which the mutation occurred.
Explanation:
Mutation can be defined as the change that occurs at the genetic level.
A frameshift mutation can be defined as the genetic mutation in which the deletion or insertion of the number of the nucleotide in the sequence of DNA results.
The frameshift mutation changes the reading frame of the group of codon from the point where the change has occurred.
This results in the completely different translation from the previous sequence.
18. During meiosis, homologous chromosomes exchange genetic material. This exchange of
genetic material -
A. increases the genetic variation
B. reduces the diploid number to the haploid number
C. increases the haploid
number to the diploid number
D. reduces the probability of mutations
A. increases the genetic variation
that's why individuals don't look like their partents. This process is called crossing-over
During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material - A. increases the genetic variation.
During meiosis, homologous chromosomes may exchange genetic material during a process called "crossing over."
Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic materialthis results in recombination of the genetic material and creates a new genetic combination. This results in variations, which can be beneficial to the offspring providing a better survival advantage.So, the correct answer is Crossing over produces new combinations of genes on alleles, increasing genetic variation.

Answer:
1)Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
2) The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion
3)onic bonds are important because they allow the synthesis of specific organic compounds. Scientists can manipulate ionic properties and these interactions in order to form desired products. Covalent bonds are especially important since most carbon molecules interact primarily through covalent bonding.
