Hurry please 50 points and please include equation. You will create a molecular clock model for an arthropod gene. Follow these guidelines to make your model:
• Your timeline will span from 90 million years ago to the present. The common ancestor in your model
is an arthropod that lived 90 million years ago. The gene that you'll track codes for a protein in the
species' venom.
• The DNA sequence you'll track contains 10 nitrogen bases. You can choose the order of the bases and
where the mutations occur.
• This gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. To build your
model, calculate the estimated time period it takes for 1 base pair to mutate.
The first time period will only show the common ancestor. At the beginning of the second time
period, three lineages will diverge from the common ancestor, each with a different mutation in their
gene sequences.
The first and third descendant species will survive for the rest of the timeline. The second descendant
species was extinct 50 million years ago.
Calculate how long it will take for one full base pair mutation to occur. Explain your reasoning by
constructing a mathematical equation.

1: the largest region of the brain is the:

  cerebrum

2. the term "psychology" literally means:

the process or procedure of the science or study of the mind.

3. the area of the brain responsible for respiration, heart rate, and smooth muscle control of our blood vessels is t

medulla oblongata

4. the structure that conducts nerve impulses to and from the brain and serves as a reflex center for some sensory information without input from the brain is the:

spinal cord

5. the three-layered membrane that covers the brain and spinal cord and literally means membrane is called the:

meninges

6. the cord-like (string-like) structures that carry bio-electrical impulses from one part of the body to another are called

nerves

7. a group of nerve cell bodies that are found outside of the spinal cord and brain are referred to as:

ganglions or ganglia (pl.) “literal meaning knot”

8. the term that means spinal cord inflammation is:

myel/itis

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
