Why are mitochondria bigger in animal cells
Greeley [361]
When you think about the main purpose of mitochondira (to produce energy; an easy idea how to remember the function of mitochondria in our bodies is to imagine them as energy factories or power plants) it becomes easy to understand why.

Animals (including us) move a lot more compared to plants. For movement you need energy and energy needs to be produced in our bodies in order for us to be able to move. Therefore, we have mitochondria that are bigger. Not only that, animal cells usually also have more mitochondria. All of this is probably done to keep up with the increased energy demands that moving organisms have.

Resistant bacteria cells illustrate what characteristics of life?
wariber [46]
I believe the answer is adaptation through evolution. Genetic diversity in populations such as bacteria, allow for new traits to be passed along during reproduction. For example, you use hand sanitizer on your hands. The hand sanitizer kills most of the germs, but a few survive and live to reproduce, passing on their immunity to certain chemicals found in the hand sanitizer. Hope this helps!

Explain how ADP is made<br>from ATP​
Lera25 [3.4K]

Answer:

However you can restore ADP with supplemental supplements for example creatine creatine will restore ADP into a ATP. So in theory it's more like a capsule for storing energy.

In the term 2pq of the Hardy-Weinberg equation. Why is the multiplication by two necessary?
Gnesinka [82]

Answer:

The correct answer is : option B.

Explanation:

Hardy–Weinberg equilibrium is a mathematical model that states that genotype percentage or frequency in a population and allele in a population remains stable or constant to generations if there are no evolutionary influences present.

Hardy Weinberg equation is :

            P²+2pq+q² = 1

Here, p² represents the frequency of genotypes dominant homozygotes (AA) in a population in equilibrium. The term 2pq represents the frequency of heterozygotes (Aa)  as there are two ways of developing heterozygous individuals either dominant from the egg and recessive from sperm or vice versa. and the term q² represents the frequency of recessive homozygotes (aa).  

Thus, the correct answer is : option B.
