I believe the answer is optic nerve
optic nerve nerves is nerves that functioned to connect the impulses from our brain to our retina and vice versa, which created the 'vision' that we get from our eyes when we look at something. On average, a human retina could possess around 770,000 and 1.7 million Axons.

I want to preface this by saying that I took Anatomy and Physiology freshman year and forgot a good chunk, but I think it's the basal ganglia...

The release of an inorganic phosphate from the myosin molecule directly results in ________

zhuklara [117]

Answer:

power stroke

Explanation:

The process of muscle contraction requires several steps.
The most famous theory on how the contraction and relaxation of muscles take place is the sliding filament theory.
However, this theory has been refined and one important addition to it is the mechanism by which myosin can pull actin and cause shortening of the sarcomere.
For the movement of myosin, it binds and releases actin and forms cross bridges.
Myosin is subdivided into two regions - S1 and S2. The contraction of the S1 region is what constitutes the power stroke.
An important requirement of the power stroke is the hydrolysis of ATP to release an inorganic phosphate which provides energy for the process.

After experimenting with the injection of various solutions into specific areas of a rat's brain and observing the subsequent ba

Maurinko [17]

The types of effects that the surgery had on the rats were documented with their bar-pressing behavior. The differences and changes from the injections effected the rats in certain ways. The location of the injection and which types that was more pleasurable for the rat is something that needs further investigation.

Identify whether or not the different agents of evolutionary change could affect allele frequencies in a population?

igomit [66]

Yes, the different frequencies of evolutionary change could affect allele frequency in a population.

<h3>What are the agents of evolutionary change? </h3>

All populations are usual in a constant state of evolution. This means that all the species are continuously changing their genetic makeup over different generations. These changes can be subtle or they can be spontaneous.

If a population is not evolving, it is said to be in Hardy - Weinberg state. In this state, the allele frequency and the genetic makeup of the population will remain the same across generations.

The agents of evolutionary change defy the Hardy - Weinberg state. These are mutation, gene flow, non-random mating, natural selection and genetic drift.

The one-toed horse of today steadily evolved from its five-toed ancestor.

Vesnalui [34]

Answer:

It is true that one-toed horse of today steadily evolved from its five-toed ancestor.

Explanation:

Evolution is the law of nature.There is a continuous process of evolution in each biological species in nature.
Similarly, horses had 5 toes millions of year back, but according to the theory of gradualism their use decreased and toes started fusing.
Now, its only one toe at present but the vestigial left over provides the solid evidence for the fact that horses had 5 toes in the past.
