RFLP, AmpFLP are the two techniques which is used to create DNA profile

Explanation:

RFLP technique: RFLP technique stands for “Restriction Fragment Length Polymorphism”. It is molecular method of genetic analysis which allows to identified based unique pattern of restriction enzyme where DNA is cutting in specific regions. It requires large amount of sample. The costing is very high

AmpFLP: The AmpFLP stands for amplified length polymorphism. It is PCR based tool. Firstly, it uses as restricted enzyme. It is cheaper than RFLP technique. It is used as genetic engineering

Which supports the idea that birds and butterflies both have wings but they do not have a common ancestor with wings?

faltersainse [42]

Birds and butterflies don't have a common ancestor because one is a member of a insect and the other is well a bird. They both have different body structure. One has bones and the other has an exoskeleton. hope this helps

Scientists studied reproduction in the New Zealand mud snail. They wanted to determine whether reproducing sexually or asexually

lubasha [3.4K]

A hypothesis is a claim that expresses a relationship between variables. D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

<h3>What is a hypothesis?</h3>

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact. It is a claim of how it works a relationship between two or more variables.

The researcher hypothesizes in order to predict what is going on or what is expected to occur.

A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relationship between the involved variables. It must be objective. Usually, it is written in the present time.

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.

In the exposed example, researchers wanted to determine whether reproducing sexually or asexually was more beneficial for the snails.

Options,

A) Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation.

The benefit of reproducing sexually is that the risk of mutation is lower.

B) Asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring.

The benefit of reproducing asexually is that a higher number of descendants are produced, which increases reproductive success.

C) Sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation.

The benefit of reproducing sexually is that it increases genetic variation.

D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

The benefit of reproducing asexually is that there is no need for social interaction.

Social interaction does not really benefit snails as a species. This is not a variable that might influence in a significant way snails.

However, variables like the mutation rate, variability, and the number of descendants are useful to test how they benefit or not the snails.

The hypotheses that would least likely aid the scientists to answer the question is option D.

The cell bodies of sensory neurons that are in clusters of neurons outside the spinal cord are called ____.

Nonamiya [84]

Answer:

The cell bodies of sensory neurons that are in clusters of neurons outside the spinal cord are called ____

The answer is "dorsal root ganglia"

Explanation:

Explanations of some terms

Sensory neurons:

Sensory neurons, also known as afferent neurons, have cell bodies that are located in the dorsal ganglia (also known as spinal ganglia) of the spinal cord. Most sensory neurons have one axon which is split into two branches, they transmit impulses toward the spinal cord.

Spinal cord:

The spinal cord is a tubular structure composed of nervous tissue housed within the vertebral column, runs from the base of the brain to the lower spine. Spinal cord is a component of the Central Nervous System that serves as information highway the between brain and the body which Integrates and processes information. It can function with the brain and can also function independently of the brain.

Dorsal root ganglia:

Dorsal root ganglia also known as dorsal ganglia originated as bipolar cells. They exists within the peripheral nervous system and they have special nerve cell clusters that aid in transmitting the sensory messages of pain and touch. The dorsal root ganglia receive information from sensory receptor organs and transmitting the information to the central nervous system.
