Answer:
only sympathetic fibers can regenerate accurately
Explanation:
Neuroregeneration is a complex biological process associated with the regrowth and/or repair of nervous tissues. This process depends on the type of nerve tissue and how seriously the nerve was injured. The autonomic nervous system, also known as the autonomic nervous system (ANS), is part of the peripheral nervous system (PNS) that is responsible for regulating involuntary physiological processes. The PNS contains two basic divisions: sympathetic and parasympathetic. The sympathetic fibers innervate tissues in nearly all the organ systems and they are responsible for regulating homeostatic processes (e.g., heart rate). The sympathetic nervous system is formed by nerves from the thoracic and lumbar segments of the spinal cord. These autonomic nerves can regenerate after injury in order to reinnervate target tissues (e.g., after chronic cardiac ischemia).

Which of the following best describes how the human nervous system and
the endocrine system work together?
O A. The nervous system signals the endocrine system to release
hormones in response to a stimulus.
O B. The nervous system responds to a stimulus, and the endocrine
system returns the body to a relaxed state.
O C. The endocrine system signals the nervous system to send out
nerve impulses in response to a stimulus.
D. The endocrine system responds to a stimulus, and the nervous
system returns the body to a relaxed state.
The nervous system usually signals the endocrine system to release hormones in response to a stimulus. The correct option is A.
What is endocrine system?The endocrine system, which is made up of all of the body's different hormones, regulates all physiological processes in the body from gestation through adulthood and to old age.
This regulation also include brain and nervous system development, reproductive system growth and function, metabolism, and blood sugar level.
The endocrine system and the nervous system collaborate to influence many aspects of human behavior, together with growth, reproduction, and metabolism. And the endocrine system is crucial in the regulation of emotions.
In response to a stimulus, the nervous system basically signals the endocrine system to release hormones.
Thus, A is the correct option.

Question:What does codominance mean in genetics?
1.Both alleles are dominant and are expressed.
2.Both alleles are recessive and are not expressed.
3.The alleles are neither dominant nor recessive.
4.Each allele is both dominant and recessive.
Option 1
that can give nice mixtures of colors in flowers, like alleles for white and red are expressed, and mixed to pink seen by the human eye
Codominance mean in genetics is the alleles that are neither dominant nor recessive. So, the correct option is (C).
What is Codominance?Codominance is a type of inheritance in which two alleles of the same gene are expressed differently to produce different types of traits in an individual.
It is a heterozygous condition in which both alleles at a single gene locus are fully expressed in the phenotype. These alleles showing an independent effect are called codominant alleles.
In codominance, neither phenotype is completely dominant nor recessive. For example, the ABO type of blood group.
The gene which control human ABO blood groups has three alleles, not just two:
[tex]I^A[/tex] and [tex]I^B[/tex]are not dominant over one another. These are dominant over [tex]I^O[/tex].
Thus, Codominance mean in genetics is the alleles that are neither dominant nor recessive. So, the correct option is (C).

The examples of natural selection are as follows:
Giraffes develop longer necks over time.A Non-poisonous snake mimics a poisonous snake.Galapagos finches choose mates with stronger and longer beaks.Peppered moths choose mates with darker colors.Thus, the correct options for this question are B, C, F, and H.
What is Natural selection?Natural selection may be defined as the methodology through which organisms that are better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. The concept of Natural selection was first proposed by Charles Darwin.
According to the question, due to the requirement of long necks in order to get food from longer trees, Giraffe develops longer necks. In order to protect themselves from predators, a non-poisonous snake mimics a poisonous snake.
On Galapagos island, if there were variations in the finches of the bird, they get a variety of food resources in order to get more nutrients and energy for survival and reproduction.
Therefore, the correct options for this question are B, C, F, and H.

When might self-fertilization be beneficial for a plant? When there are too many dioecious individuals in a population, self-fertilization becomes beneficial for a monoecious individual. When environmental conditions are harsh, such as a plant growing in nutrient-poor conditions, or when herbivores have damaged the plant, plants may self fertilize. When environmental conditions are perfect, plants can afford to self-fertilize. Only plants with perfect flowers are capable of self-fertilization.
Answer:
Only plants with perfect flowers are capable of self-fertilization.
Explanation:
Self-pollination is the process that allows plants to fertilize themselves. This process is very beneficial when a plantation has plants with few flowers or when the plants are spaced far apart.
However, only plants with perfect flowers can self-fertilize. This is because for self-fertilization to occur, the plant needs to have flowers that present the male and female reproductive organs, which allows the same flower to produce pollen that will be sent to its own ovary. Only perfect flowers have male and female reproductive organs at the same time.

Answer:
Death of coral reefs occurs due to increasing the temperature of the ocean.
Explanation:
Death of coral reefs occurs due to increasing the temperature of the sea and ocean because warm water killed the algae attached to the surface of coral reefs which causes bleaching of coral reefs. This coral reefs provides habitat as well as food to thousands of animals present in the ocean ecosystem so the destruction of coral reefs causes death or migration of animals from that region.

In fruit flies, long wings are a dominant trait (L) and short wings are a recessive trait (l). Two fruit flies that are heterozygous for the long wings trait mate. The cross produces 180 offspring. How many of the offspring are expected to have short wings?
Answer:
45
Explanation:
Both parents are hetero-zygous, so each has alleles Ll.
When Ll crosses with Ll, we have
LL 25%
Ll 50%
ll 25%
So out of 180 offspring, we expect about 25% to have short wings, or
25%*180 = 45
