Answer:

A. differentiation

Explanation:

Cell differentiation consists of a set of processes that transform and specialize embryonic cells. After these transformations, their morphology and physiology are defined, which make them capable of performing a certain function.

We call differentiation in biology the process that all living cells go through to specialize in a particular function. These cells, despite being differentiated, continue with the same genetic code as the first cell, and the difference between them is in inhibiting or activating certain groups of genes - these responsible for defining the function of each of them. This, in addition to determining its function, entails some changes in cell structure, as happened with the cell described in the question, which promoted a change in its structure by merging with neighboring cells to form a multinuclear tube.

Which statement below describes a feature that is shared between kinesin and dynein? a. Both proteins "walk" towards the (+) end
spin [16.1K]

Answer:

C)Both proteins bind ATP and F-actin

*C option is not mentioned* there is a flaw in the question

Explanation:

Two families of motor proteins, kinesin and dynein, transport membrane-bounded vesicles, proteins, and organelles along microtubules. Nearly all kinesins move cargo toward the (+) end of microtubules (anterograde transport), whereas dyneins transport cargo toward the (−) end (retrograde transport).While

both the protiens have globular ATP-binding heads that function as the motor domain and interact with the microtubules.

Suppose that a glutamine residue in the active site of an enzyme was mutated to alanine. As expected, the alanine mutant was ina
likoan [24]

Answer:

A to N

Explanation:

Glutamine is an amino acid with a polar, uncharged side chain. The mutation to alanine, an amino acid with a non-polar side chain, completely affects the enzymatic activity. This makes sense considering the difference in the nature of both amino acids.

To restore the wild-type level of activity the alanine would have to mutate to another polar uncharged amino acid. Among the given options, only Asparagine (N) has a similar chemistry to Glutamine.

vladimir2022 [97]
After collecting evidence that concludes that the current plan to manage the Alaska crab fishery makes it only a potentially renewable resource, m<span>ore research should be done into the reproductive behaviors of the different species. This solution tries to solve the problem at its roots. That is, if the management determines why there are fewer species based on their reproductive behaviors, certain changes can be made in order to create an environment that will enhance their reproduction. </span>
