The question is incomplete as it does not have the options which are-

a. migration

b. genetic drift

c. mutation

d. stabilizing selection

Answer:

The correct answer will be option- migration

Explanation:

Migration refers to the long-distance movement of the individual, group and population. The migration enables the flow of genes from one population into another called gene flow. Migration is the strongest force of gene flow after selection.

In the given case, since the allele frequency of the population has changed due to the migration of the 200 snakes from a population of 5000 snakes, therefore, migration is the correct answer.

The most common fossils are of: vertebrates invertebrates bacteria plants
Nat2105 [25]

Answer:

Invertebrates

Explanation:

Most of the fossils belong to invertebrates. Invertebrates make around 95% of all the animal species. Invertebrates do not have bones that are present in vertebrates. The soft body parts of invertebrates form impressions and their exoskeletons and shells also form fossils. Bones of vertebrates are scattered after the death of the organisms and makes their fossils rare.

Which of the following statements about the autonomic nervous system is not true?
velikii [3]

Answer:

The statement B that says ''All of the fibers are afferent fibers'' is not true.

Explanation:

The autonomic or vegetative nervous system (ANS), also called neurovegetative or involuntary, is the part of the nervous system that is responsible for innervating the structures or organs related to the internal involuntary activities necessary for the functioning of the organism, such as the heart, the pupils , the glands among others.

It is considered mostly as an efferent system. Its efferent pathways are formed by two types of neurons, which are the preganglionic and postganglionic, and the synapse between these fibers, forms the autonomous ganglia. Afferent impulses range from visceral receptors, chemoreceptors, osmoreceptors and baroreceptors to the central nervous system.

Anatomically, it is divided into two autonomous nervous systems: the sympathetic and the parasympathetic. The functions of both are antagonistic, thus achieving a functional balance that tends to maintain body homeostasis. These divisions originate from the central nervous system and represent the efferent pathway through which it communicates with visceral effectors. The sympathetic nervous system increases energy expenditure against adverse conditions, dilates the pupil. The parasympathetic nervous system, prevents excessive energy expenditure, contracts the pupil.

Cell bodies of sensory neurons may be located in ganglia lying outside the central nervous system. Cell bodies of sensory neuron
AlekseyPX

Answer:

True

Explanation:

Sensory neurons are the neurons present in the nerves which can convert the external stimuli into an electrical signal and can transmit the signals from the organs to the central nervous system.

The structure of sensory neuron in pseudounipolar that is at one end it has dendrites and another end transmits the signals to the CNS. The cell bodies  (nucleus) of these sensory neurons are located in the structures called ganglia located outside the CNS.

Thus, True is the correct answer.
