The correct answer is B.
Explanation:
The fibroblast is a dynamic cell, which exerts tissue functions at the local level and the immune system. Among its main functions is the formation of connective tissue fibers called collagen and elastin; The fibroblast performs other equally important roles such as: The production and maintenance of the fundamental substance in which its fibrous products are embedded, it has the ability to synthesize and phagocytize collagen and extracellular matrix components in connective tissue remodeling processes.
Jacob a 40 year old man who is 6 foot tall and weighs 225 pounds has been diagnosed with atherosclerosis. What healthcare plan would you design for this patient? prescribe a medication to reduce bad cholesterol and no other changes need to be made. patient is just slightly overweight and she is worrying to much about his health, therefore no change. patient should make lifestyle changes to healthier foods and start an exercise plan to reduce his weight by 30 pounds prescribe a medication that lowers blood pressure and no other changes need to be made.
Answer:
The patient should make lifestyle changes to healthier foods and start an exercise plan to reduce his weight by 30 pounds.
Explanation:
We know that the patient weighs 225 pounds, and his height is 6 feet. With this information, we can determine his Body Mass Index (BMI) using the formula:
BMI= weight/(height)²
BMI= 225/(6)²
BMI= 30.5
Once that we calculated his BMI, we compare the result with the reference chart, here we can see that for his height. he is obese. This coincides with the fact that he has been diagnosed with atherosclerosis. His body has been placing the extra fat in the arteries.
The best plan for Jabob would be to make a lifestyle change to healthier foods and an exercise plan that helps him to lose weight so that his BMI would be approximately 25 and his weight of 195 pounds. Also, this plan will reduce cholesterol levels.

3. Why is it easy to describe an organism's phenotype for a particular characteristic but
very difficult to state the genotype?
Answer:
The sum of an organism's observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism's parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype

Explain why one cell would have so many different kinds of proteins embedded in the cell membrane
Answer:
membrane proteins play different roles (for example, transport of nutrients, signaling pathways, etc)
Explanation:
Membrane proteins are key components that form and interact with biological membranes. Thus, membrane proteins can be classified as 1-integral membrane proteins which are components of the cell membrane and 2-transmembrane proteins that penetrate the membrane in one or both sides of the membrane. These proteins account for different cellular functions. Some functions of membrane proteins include:
- Cell structure (attachment to the extracellular matrix and/or the cytoskeleton)
- Transport of nutrients and waste products
- Intercellular interaction between cells.
- Signaling transduction functions
- Cell recognition (e.g., during innate immune responses)
Answer:
Each type of cell has, in its cell membrane, specific proteins that help it control the intracellular environment and that interact with specific signals from its environment.
Explanation:
Some proteins are completely integrated into the membrane and are called membrane proteins or integral transmembrane proteins since they "cover" both layers of the membrane. Transmembrane proteins are useful to the cell because they can interact with molecules outside the cell and send information about the extracellular environment into the cell. Other proteins are more loosely bound to the inside or outside of the membrane and are called peripheral membrane proteins. Peripheral membrane proteins are often used by the cell during signal transduction - the process by which one cell responds to a signal from another cell.
Scientists are concerned that melting glaciers are exposing long frozen animals. When the ice melts, the animals thaw and begin to decompose. How will this affect the amount of co2 in the atmosphere?
As the Earth warms, scientists worry that some of the carbon in permafrost could escape to the atmosphere as carbon dioxide or methane. Increasing the amount of these gases in the atmosphere could make Earth's climate & more
Explanation:yw
The process of decomposition increases the amount of carbondioxide gas in the atmosphere.
The process of decomposition greatly affect the amount of carbondioxide in the atmosphere because in the process of decomposition, carbondioxide is released in the atmosphere which is added to the carbondioxide present in the atmosphere.
This results in more warm temperature of the earth atmosphere so we can conclude that the process of decomposition increases the amount of carbondioxide gas in the atmosphere.

A particularly long radio wave has a wavelength of 1.5 x 10^9 meters. What is the frequency of this radio wave?
Answer:
0.2Hz
Explanation:
The wavelength of a radiowave can be calculated this;
λ = v/f
Where;
λ = Wavelength (m)
v = speed (m/s)
f = frequency (Hz)
Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?
Hence, using λ = v/f
f = v/λ
f = 3 × 10^8 ÷ 1.5 x 10^9
f = 2 × 10^(8-9)
f = 2 × 10^-1
f = 0.2Hz
Which statements describe incomplete dominance? Select three options. Traits are usually dominant. Traits are neither dominant nor recessive. Offspring exhibit an intermediate form of alleles from the parents. Both alleles, one from each parent, are expressed in offspring. Incomplete dominance involves the interaction of two alleles. which ones are right?
Answer:
Traits are neither dominant nor recessive.
Offspring exhibit an intermediate form of alleles from the parents.
Incomplete dominance involves the interaction of two alleles.
Explanation:
In genetics, incomplete dominance (also known as partial dominance) is produced when the dominant allele doesn't mask the effects of the recessive allele, which is also expressed in the phenotype. In consequence, heterozygous organisms for a gene exhibiting incomplete dominance will be a mix (or blend) as a result of the expression of both characters. In humans, for example, Tay-Sachs disease is a genetic disorder characterized by a gene that exhibits incomplete dominance, where heterozygous individuals are still able to produce a key enzyme (hexosaminidase A) due to expression of the wild-type allele, while homo-zygous individuals for Tay Sachs recessive mutation usually die by the age of 4.

How are catastrophic events related to changes in geological timelines?
A. They aren't related to changes in the geological timeline because they don't change the
overall population dynamics.
B. They aren't related to changes in the geological timeline because the timeline is dictated
by temperature cycles.
C. They cause significant changes that disrupt the equilibrium of the earth and lead to
natural separation points.
D. They define geological periods because scientists use them as reference points for
tracking the history of the earth.
PLEASE ONLY ANSWER IF YOU KNOW-
Answer:
D. They define geological periods because scientists use them as reference points for tracking the history of the earth.
Explanation:
Catastrophic events related to changes in geological timeline are very useful in defining geological periods.
These events have very significant appearance in the geological record and can be used to determine the history of the earth.
The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.
Geologists use these events that are often wide spread to delineate geological periods.
When comparing animal to plant cells, they are different in size, shape, and how they store energy. They have similarities, as well. Which organelles perform similar functions in both plant and animal cells. Group of answer choices D. Ribosome, cell membrane, chloroplast C. Cell membrane, cell wall, nucleus
Answer:
ribosome, cell membrane, nucleus
Explanation:
The organelles that perform similar functions in both plant and animal cells among the listed organelles would be the ribosome, the cell membrane, and the nucleus.
First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.
The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.
How does melting glaciers affect the water cycle

If you were to test a small
sample of soda lime with
universal indicator would it
register a pH above or
below 7? Explain your answer
The soda contains CO2 that is dissolved CO2 reacts with water
CO2+H2O--->H2CO3
to form carbonic acid
this is a weak acid but it gives protons to water
H2CO3+H2O-->-HCO3+H30+
pH=-lg[H3O+]
[H3O+] is the molar concentration
Therefore the acid present in the solution causes the pH to be lower than 7. It can either be the H2CO3 if it is a carbonated beverage or citric acid from lime juice.

24. Not clear, maybe 18%
25. Left ventricle, because according to the graph nearly 50% of the organ contains mitochondria, more than the left atrium.
Explanation:
22. Active transport requires cell's energy to move molecules, usually in the form of ATP.
23. This is a trick question, you might think it is diffusion or osmosis, but is is exocytosis. Diffusion and osmosis don't require vesicles for transport. It isn't endocytosis, because that is moving molecules inside the cell. The question asks for moving out the cell.
24. Look at the chart, it is less than 20, but more than 10 and more than halfway. I am not sure exactly the percentage, I would approximate it to be 18%.
25. Most likely left ventricle.
