1. All the energy in this pyramid came from the sun because all the producers at the bottom of the pyramid get their energy from the sun.

2. The level with the most organisms would be the bottom level.

3. The least amount of energy is found at the top of the pyramid since 90% of the energy is not passed on.

4. The other 90% of the energy from the producer is unusable to the organism

(1) and (3) are obviously wrong.
If thy stop reproducing then the whole population could die and (3) is just crazy.

suter [353]

Answer:

Three properties of myosin motors are a step size, duty ratio, and tail interactions.

Explanation:

Myosin is an actin motor protein.

The primary function of the myosin is to convert ATP to energy. Duty is the fraction of ATP cycle to actin.

Step size means displacement during 1 ATP cycle. Step size of myosin was found out by measuring the velocity of different filament size of myosis.

Muscles contraction, chemo taxis, cytokinesis is some function that can be related with among the family.

Correct option is C. This evidence supports the claim that natural selection can produce new structures by coupling together parts of other structures.

<h3>How are gene variants involved in evolution?</h3>

Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes. Genetic variations can arise from genetic variations (also called mutations) or from a normal process in which genetic material is rearranged as the cell is about to divide (known as genetic recombination).

Genetic variations that alter gene activity or protein function can introduce different traits into an organism. If a trait is beneficial and helps the individual survive and reproduce, the genetic variation is more likely to be passed on to the next generation (a process known as natural selection).

Over time, as generations of individuals with the trait continue to reproduce, the favorable trait becomes more and more common in a population, making that population different from the ancestral population. Sometimes the population becomes so distinct that it is considered a new species.
