Answer: <em>The Bottleneck Effect</em>

Explanation:

A Bottleneck effect is the sharp reduction of numbers of a population through environmental effects or human activity. It causes a loss of the genetic pool and its variety; genetic variation lowers and increases with time as random mutations occur.

In mitochondrial electron transport, what is the direct role of.

horrorfan [7]

Answer:

O2 participates in cellular respiration

Explanation:

The only place that O2 participates in cellular respiration is at the end of the electron transport chain, as the final electron acceptor. Oxygen's high affinity for electrons ensures its success in this role.

The inability of organisms to evolve anything that could be an advantage reflects _____.

sergey [27]

The inability of organisms to evolve anything that could be an advantage reflects "the limit of historical constraints".

<h3>What is the limit of historical constraints of evolution?</h3>

Although evolution is a powerful process that leads to

rapid changes in the characteristics of organisms, limits

to evolution arise from a lack of genetic variation, a

loss of well-adapted genotypes in populations due to

gene flow, trait interactions leading to trade-offs, and/

or the difficulty of evolving simultaneous changes in a

number of traits. This is the limit of historical constraints of evolution.

<h3>What are the factors that can cause an organism to evolve?</h3>

Four main factors lead to evolution:

(1) the potential for a species to diversify;

(2) heritable genetic variation among individuals within a species as a result of mutation and sexual reproduction;

(3) competition for scarce resources; and

(4) the spread of organisms that are better able to endure and procreate in the environment.

Classify each description as being a characteristic of microtubules, intermediate filaments, or actin filaments.

AlekseyPX

I found the exercise on the internet and attached are the descriptions.

Actin filaments:
-"play a role in cleavage furrow formation during cell division"
-"function in muscle contraction"

Microtubles:
-"make up the core of cilia and flagella"
-"are composed of tubulin subunits
-"maintain cell shape by resisting compression"

Intermediate filaments:
-"are not involved in cell motility"
-"fix certain organelles in place"
