Answer:
We can tell that extinctions have occurred in the past by looking at fossils in layers of sediments. If the amount of fossils found match you can infer that they are the same organism and they are extinct. If you can't match up the bones with any animal today.
Hope this Helps!
Answer:
a. Rotation of the shaft protein driven by the proton gradient
Explanation:
The F1 portion of ATP synthase is hydrophilic and responsible for hydrolyzing ATP. The F1 unit protrudes into the mitochondrial matrix space. ... γ subunit allows β to go through conformational changes (i.e., closed, half open, and open states) that allow for ATP to be bound and released once synthesized.
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.
Bone marrow is the spongy, fatty tissue inside your bones. It creates the following parts of the blood: red blood cells, which carry oxygen and nutrients throughout the body. white blood cells, which fight infection. platelets, which are responsible for the formation of clots.
So, the answer is C: Red and White Blood Cells!!
Hope that helped!! :)
Plant Breeding and Predicting Offspring Traits

Introduction
Kernel color in an easily observable trait. There are different alleles of the ‘kernel color’ gene that code for different colored kernels. For example, one allele represented with Y (upper-case) encodes yellow colored kernels. Another allele for the color trait encodes white colored kernels represented with the y (lower-case).
