C) The Earth is at least three billion years old. :)
Answer:
All of these are correct.
Explanation:
ATP synthase is an F type pump with two multiprotein complexes. One of the protein complexes has three types of integral membrane proteins a, b and c while another protein complex has five polypeptides with distinct composition. It has three copies of each alpha and beta subunits and one copy of each gamma, delta and epsilon subunits.
The beta subunits have a binding site for ADP and Pi and catalyze ATP synthesis. Rotation of gamma subunits relative to the fixed alpha and beta subunits causes the catalytic binding site of each beta subunit to obtain either of three conformational states.
An O state has a high low affinity for ATP, ADP, and Pi while L state has a high affinity for ADP and Pi. The T state binds to ADP and Pi tightly to facilitate the formation of ATP. The T state also has a high affinity for ATP.
Cells could sense and respond to electromagnet signals such as light and mechanical signals such as touch. Cells often communicate with each other using chemical signals.
<u> Allele frequencies to change from one generation to the next.-</u>
<u>B. </u><u>Mutation</u><u>; C. Random genetic drift; D. </u><u>Migration</u><u>; F. Natural selection</u>
- Selection, mutation, migration, and genetic drift are the mechanisms that effect changes in allele frequencies.
- When one or more of these forces are acting, the population violates Hardy-Weinberg assumptions, and evolution occurs.
Why do allele frequencies change from one generation to the next?
Random selection: Allele frequencies may fluctuate from one generation to the next when people with particular genotypes outlive those with different genotypes.
No mutation: Allele frequencies may fluctuate from one generation to the next if new alleles are produced via mutation or if alleles mutate at different rates.
What are 5 factors that cause changes in allele frequency?
- A population, a collection of interacting individuals of a single species, exhibits a change in allele frequency from one generation to the next due to five main processes.
- These include natural selection, gene flow, genetic drift, and mutation.

First Gap: The cell is growing in size and is beginning protein synthesis. D<span>uplication is happening.
Synthesis: </span><span>DNA is duplicated so that each chromosome contains two identical copies.
Second Gap: Continues to grow in size and making the amount of protein it needs, also confirming the DNA has no errors in it.
(Also after this the GO phase starts to happen)
