4 0

Answer:

because a change in the DNA sequence

Explanation:

Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression. Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism.

SSSSS [86.1K]

Answer:

1. Apoplastic

2. Symplastic

3. Symplastic

4. Apoplastic

Explanation:

The interconnected porous cell walls of plant cells make apoplast along which water is allowed to move freely. Symplast refers to the path made up of interconnected cytoplasm of many plant cells connected by plasmodesmata. Therefore, water and dissolved minerals enter the root cortex from the epidermis in the solution can move through symplast and apoplast till endodermis.

Water and dissolved minerals present in the cytoplasm of cortical cells move from one cell to next via plasmodesmata (the symplast) while the ones present in their cell walls and intercellular space move through apoplast. The presence of casparian strips in the endodermal cell wall does not allow the movement of water and minerals through the apoplast.

Geneticists have determined that the majority of individuals in an isolated island population have blood type
oee [108]

Question continuation;

..........type B. Type A is found to be more common in the mainland population from which the island was settled.

How could a geneticist best explain the dominance of blood type B in the island population?


Multiple choices;

A. Random mutations have occurred in the island population.

B. Genetic drift has reduced the frequency of type A individuals.

C. Natural selection has only occurred in the mainland population.

D. Environmental conditions on the island are less favorable for type B individuals.


Answer;

B. Genetic drift has reduced the frequency of type A individuals.


Explanation;

-Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance.

-It occurs in all populations of non-infinite size, but its effects are strongest in small populations.

Using ideal ATP production numbers, how many ATPs would an individual generate if he or she consumed only pyruvate and carried o
IrinaK [193]

Answer: The ATP(Adenosine Triphosphate) that will be generated if one pyruvate molecule is carried through cellular respiration is 36.

Explanation: Pyruvate is formed through glycolysis cycle which breaks down glucose. The pyruvate is used in aerobic cellular respiration via the TCA cycle yielding 2 ATPs and the electron transport system yielding 34 ATPs. That makes it up to a total of 36 ATPs.
