The autonomic nervous system is responsible for regulating involuntary body activities.
The nervous system coordinates the bodily functions of muscles to produce actions.Involuntary activities such as circulation, heartbeat, digestion, breathing, and peristalsis for example are generally not under our conscious control.
These are otherwise known as involuntary actions controlled by the autonomic nervous system which in turn is a subdivision of the peripheral nervous system (this system branches off the spinal cord to all other parts of the body.
Other parts of the nervous system would be the central nervous system divided into:

What do animals need to survive and reproduce
Animals need features such as nutrition, movement, respiration, response to stimuli, growth, and excretion in order to survive.
Survival of animalsIn order for an animal to survive, the following must be observed:
Nutrition: the animal must feed. Food gives energy and supplies the necessary nutrients for growth and repair.Movement: animals must be able to move away from dangers and in search of food.Respiration: the consumed food must be broken down and this can only happen by respiration.Growth: only by growing and developing will an animal be able to reach maturity and reproduce.Excretion: unused foods must be removed from the body due to their toxicity to the body.More on animal survival can be found here: https://brainly.com/question/2759539

What role does the sclerenchyma play?Sclerenchyma's primary job is to offer mechanical support. They are made up of lengthy, slender cells that have a thick lignified wall. They lack protoplast and are largely dead.
The complete chart and table are given in the image attached.
A basic permanent tissue known as parenchyma makes up a large portion of the ground tissues of plants, where vascular tissues and other tissues are attached. They are non-vascular and made up of undifferentiated, primitive living cells that have undergone modifications to carry out distinct tasks.
Xylem, along with phloem and cambium, is a key component of vascular tissue. Its primary functions include providing mechanical support and storage as well as moving water and solutes from the plant-soil interface to the stems and leaves.
Parenchyma cells, are also a component of phloem and are essential for the storage of water, non-structural carbohydrates, and storage proteins.

What are some possible benefits and dangers if the DNA is used to create a mutant form of the organism?
Explanation:
The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.
Many other mutations have no effect on the organism because they are repaired beforeprotein synthesis occurs. Cells have multiple repair mechanisms to fix mutations in DNA. One way DNA can be repaired is illustrated in Figure below. If a cell’s DNA is permanently damaged and cannot be repaired, the cell is likely to be prevented from dividing.

The word transcribe means 'to write out' and the word translate means 'to express in a different language'. Review the meanings of transcription and translation in protein synthesis. How do the technical meanings of these words relate to meanings of the words in ordinary language.
The word transcribe means 'to pass the code from DNA to RNA', whereas the word translate means 'change from mRNA to protein', which is a different language.
What is the genetic code?The genetic code is a series of instructions that indicate how to synthesize proteins from a given gene sequence.
During transcription, the DNA gene sequence is transcribed into a messenger RNA (mRNA).
During translation, triplets of nucleotides or codons in mRNA determine specific amino acids in the growing protein sequence.
In conclusion, the word transcribe means 'to pass the code from DNA to RNA', whereas the word translate means 'change from mRNA to protein', which is a different language.

Leopard seals also eat krill.
A decrease in the number of krill will affect the crabeater seals sooner
than it affects leopard seals.
Give the reason for this.
if the number of individuals in the krill decreased, then the crab and crabeater seal populations would decrease because there would not be enough food for all of the individuals of their populations to eat.

B. genetic material
C. energy storage
D. cell waste
Answer:
C
Explanation:
ATP has to do with energy so the correct answer would be energy storage.
The one that describes ATP is energy storage. The correct option is C.
What is ATP?A chemical that is a part of all living cells and gives energy to a variety of metabolic processes, including the production of RNA.
In patients with advanced solid tumors, the effects of laboratory-produced ATP on weight loss and muscle strength are being investigated. Likewise known as adenosine triphosphate.
The principal energy source for critical biological processes such muscular contraction, nerve impulse transmission, and protein synthesis is ATP generated in mitochondria.
For example, large levels of ATP signal that the cell has enough ATP and does not need to produce any more through cellular respiration. In this instance, a product "feeds back" to block its pathway, which is a form of feedback inhibition.
Thus, the correct option is C.
