Combining your knowledge of rates of diffusion with your knowledge of muscle physiology, explain why it is advantageous for oxidative muscle fibers (which depend on aerobic metabolism to generate ATP) to have smaller diameters compared to glycolytic muscle fibers.
Answer:
To provide quick energy to the muscles.
Explanation:
It is advantageous for oxidative muscle fibers to have smaller diameters compared to glycolytic muscle fibers because these fibers depend on aerobic respiration to provide energy to muscle contractions. This smaller diameter enables the oxidative muscle fiber to move very quickly in order to provide quick energy to the muscles. If their diameters are big so they are unable to provide quick energy in the form of ATP to the muscles for their contractions.

What does "plate margin" mean?
Answer:
plate margin (plate boundary) The boundary of one of the plates that form the upper layer (the lithosphere) and together cover the surface of the Earth. Plate margins are characterized by a combination of tectonic and topographic features: oceanic ridges, Benioff zones, young fold mountains, and transform faults.

Please WHAT IS MEMBRANE POTENTIAL
Answer:
Membrane potential is a potential gradient that forces ions to passively move in one direction.

What is the correct sequence of events that occur during protein synthesis?
1.mRNA is formed
2.amino acids form polypeptides.
3.a strand of dna segment unwinds.
4.mRNA attaches to ribosomes.
5.tRNA supplies the required amino acids.
Answer:
3, 1, 4, 5, 2
Explanation:
DNA helicase enzyme will unwind DNA into 2 segments for a template. Complementary nitrogenous bases will attach themselves to one of the DNA strands. mRNA carries codons for instructions from DNA. mRNA leaves the nucleus and joins with a ribosome (tRNA) in the cytoplasm. tRNA has anticodons which are complementary to a specific mRNA molecule. tRNA pairs with and translates instructions that the mRNA is carrying. Each amino acid delivered to the ribosome by tRNA begins forming a chain of amino acids, called a peptide bond.

In a population of birds, the average beak size is favored. What type of selection is this?
a. directional
b. disruptive
c. tabilizing
d. kin
Answer:
C. Stabilizing selection
Explanation:
Natural selection, is of three different types namely: disruptive selection, directional selection and stabilizing selection. Disruptive selection occurs when the two extremes of a population are being favored over the average or intermediate.
Directional occurs when one extreme of a population is favored. However, in STABILIZING SELECTION, the average or intermediate population is favored over both extremes of a population. Example is when the average-sized beaks of a bird population is being favored over the long and short ones (extremes).
Answer:
the answer is stabilizing.

Scientists looking for a repressor of the androgen receptor (AR)-mediated transcription gene discovered a protein, Ankrd1. ARs were observed to bind to Ankrd1 and, in cells where Ankrd1 was over-expressed, AR-mediated transcription was inhibited. The scientists also detected lower levels of ARs when Ankrd1 was overexpressed using chromatin immunoprecipitation (ChIP) and Ankrd1 was not detected by ChIP.Based on these observations, which of the following conclusions would the scientists most likely draw?
A. Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription
B. Ankrd1 is binding to the promoter and blocking ARS from binding, which prevents transcription of AR- mediated genes.
C. Ankrd1 is binding to multiple sites and causing DNA to loop, preventing ARS from binding and activating gene transcription
D. Ankrd 1 is binding to chromatin, recruiting proteins that remove acetyl groups, and silencing transcription of that region of DNA.
Answer:
D. Ankrd 1 is binding to chromatin, recruiting proteins that remove acetyl groups, and silencing transcription of that region of DNA.
Explanation:
Ankrd is a binding chromatin, there is recognition that mutation is deregulating the chromatins. The proteins remove acetyl groups and then the region for DNA transcript. The recruitment chromatin is associated with proteins are enzymes which are chemical moieties.

Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription

As Earth's climate changes, which of the following do scientists expect?
The correct option is (c) Decreased Biodiversity.
The term "biodiversity loss" describes the reduction or extinction of biological diversity, which is defined as the range of living creatures that inhabit the earth. their various degrees of biological organization, their individual genetic variability, and the natural patterns found in ecosystems.What is causing the biodiversity to decline?The variety of all living creatures on our world, known as biodiversity, has been decreasing at an alarming rate in recent years. This decline is primarily attributable to human activities such changing land use, pollution, and climate change.The main direct cause of biodiversity loss is land use change (primarily for large-scale food production) which drives an estimated 30% of biodiversity decline globally.Learn more about Decreased Biodiversity brainly.com/question/18200563

4. What is the difference between a Nucleolus and a Nucleoid?
The nucleus is the largest and the most important cell organelle in a eukaryotic cell. A nucleus is a membrane-bound organelle that houses the genetic material of eukaryotes in DNA. The nucleus consists of protein fibres or the DNA inside chromatin fibres. Nucleoids contain the genetic material of prokaryotes in the cytoplasm. The nucleoids usually consist of a single chromosome.
Let us look at more difference between nucleus and nucleoid in the table given below.
Answer: It has different letters.
Explanation: Nucle = prefix.
Olus in Nucleous and Oid in Nucleoid

Which of the following statements concerning diffusion and active transport is correct?
A. Active transport requires energy while diffusion does not
B. Diffusion requires energy while active transport does not
C. Both processes require energy
D. Neither diffusion nor active transport requires energy
Answer: A
Explanation:
Active transport requires energy while diffusion does not
Active transport pumps molecules and ions against a concentration gradient. Thus, option A is correct.
What is the main role of active transport?As contrast to assisted diffusion, which carries molecules or ions along a gradient of concentration without the application of energy. An organism occasionally needs to transfer items up or down a gradient of concentration.
In order for cells to acquire molecules or ions from the environment in opposition to the concentration gradient, active transport is a crucial activity.
Because active transport is not passive and requires molecules to move against a concentration gradient, it requires energy.
On the other hand, metabolic products or electrolytes that are substantially loaded into cells might be expelled in opposition to the concentration gradient.
Therefore, Active transport requires energy while diffusion does not.

Cytokinesis in animal cells happens when the:
A: cell wall pinches in to separate the cytoplasm.
B: cell plate forms across the middle of the cell.
C: chromosomes line up in the middle of the cell.
D: cell membrane pinches in to separate the cytoplasm.
Answer: D
Explanation:
Cytokinesis is basically the formation of 2 new cells. C describes metaphase and A and B are talking about cytokinesis in a plant cell because animals don't have cell walls or plates. So the right answer has to be D
