Answer:

Answered below

Explanation:

Electroencephalography produces a record of the electrical activities in the brain. An electroencephalography is a test used to diagnose brain conditions such as epilepsy and other seizure disorders. Electrical activities are displayed on the electroencephalogram.

Functional magnetic resonance imaging produces images of brain structure and function. It shows the functional processes of the brain such as blood flow and neuronal activations.

The positron emission tomography scan produces images of metabolic activities in the brain. It uses radioisotopes to show the distribution of chemicals or neurotransmitters and measure the metabolic activities.

Computed tomography scan is uses many X-rays to produce images of brain structures. It is used in the diagnosis of many structural abnormalities.

Magnetic resonance imaging produces images of brain structures by the use of magnetic impulses. It is a lot safer as it doesn't produce dangerous radiations.

Can evolution create new species over time through natural selection?

is the question he would be prompted to ask based on his voyage.

<h3>Who was Charles Darwin ?</h3>
  • English scientist Charles Darwin gained notoriety for his theory of natural selection, which postulated that organisms in an ecosystem adapt and evolve in order to maintain their survival.
  • Because of this, Darwin was inspired to consider whether natural selection can eventually result in the emergence of new species after studying the selective breeding of pigeons.
  • Darwin came to the following conclusion based on these straightforward observations:
  • In a population, some individuals would have hereditary qualities that assist them survive and reproduce (given the conditions of the environment, such as the predators and food sources present).

What is the job of tRNA
exis [7]

Answer:

To make our mRNA

Explanation:

I think it is this one, but I am not sure, sorry if it is wrong. :(  

But I do know this, I think it might help you:

A transfer RNA (tRNA) is a special kind of RNA molecule. Its job is to match an mRNA codon with the amino acid it codes for. You can think of it as a kind of molecular "bridge" between the two. Each tRNA contains a set of three nucleotides called an anticodon.

solniwko [45]

Answer:

D

Explanation:

A group or member of a species would overtime become differentiated from the original species that originate from if they occupy a different niche that has a different and unique environmental conditions. In an attempt to adopt to the condition of the new environment, they would develop specific features. For example, the honeycreepers having a bill that are well adapted to eat certain foods.

Therefore, the most likely conclusion the scientist would make is D.
