The correspondence of the description with the correct nervous system is listed below:
A. It carries messages to your brain via your spinal cord: the central nervous system. B. If you stub your toe, it carries a message: peripheral nervous system.
C. This releases hormones: the autonomic nervous system.
D. This allows you to move your body voluntarily: the somatic nervous system.
E. This revs up your body when you need energy: the sympathetic nervous system
The central nervous system is made up of the brain and spinal cord. Generates the correct response based on the stimulus. The peripheral nervous system includes motor and sensory neurons connected to the central nervous system. The somatic nervous system is associated with voluntary body movements, and the autonomic nervous system controls involuntary movements.
answer 2
Central: carries messages to your brain via the spinal cord
Peripheral: If you stub your toe, bring a massage
Autonomic: This releases hormones.
Somatic: This allows you to move your body at will.
Cute: This speeds up your body when you need energy.

b. Regular blood tests should be done to detect the presence of tumor markers or abnormal cells.
C. You should have a genetic test to determine if you carry the cancer gene.
d) You should reduce your exposure to ultraviolet radiation and check your skin regularly.
answers
Answer: Option D
Explanation:
Skin cancer is very common today because UV exposure is on the rise. Skin cancer only occurs when the body or skin specifically comes into contact with harmful ultraviolet radiation found in sunlight.
It can be defined as the abnormal growth of skin cells. This cancer can also appear on skin that is not normally exposed to sunlight. These can be melanoma, basal cell carcinoma, squamous cell carcinoma.
Prevention of this disease is the regular use of a sunscreen formula on sun-exposed areas. Shorten exposure time and regular examinations by a dermatologist.
D. You should minimize exposure to ultraviolet radiation and check your skin regularly.

Explanation:
The horsetail plant is scientifically known as Equisetum and belongs to the Sphenophyta species. It is a bushy perennial herb that grows along river banks in moist soil. The plant body is a sporophyte and is divided into root, stem, and leaves. The stems are joined with nodes and internodes, internodes with ridges and grooves and holes. At the stem nodes, small scaly leaves develop on the spines.
The answer is B. It is horsetail and belongs to the species Sphenophyta.

This segment of DNA mutates at a rate of one base pair every 33 million years. The type A mtDNA sequence with TACAAGATAC and the type B mtDNA sequence with TACGCGTAAC. According to these DNA sequences, 66 million years ago, the two species diverged from a common ancestor. So option C is correct.
What is a mutation?
A mutation can be defined as a change in the nucleotide sequence of the genome of a living organism, either DNA or RNA, due to various environmental factors, such as ultraviolet light and errors in DNA replication.
Many mutations are neutral, and some are harmful, but also beneficial in some way. It can be transmitted from parent to child. Some other causes are chemicals or excessive radiation.
There are four types of gene mutations of mutation, somatic mutation, germline mutation, and chromosomal mutation.
In the case of a gene mutation, there is a mutation in the DNA, there is a change in one or more nitrogenous bases, which ultimately affects the proteins that are the product and their expression.

What is the most important factor that defines desert biomes? Why are deserts divided into different types?
answers
a major defining factor of a desert boom is its tendency to lose water through evaporation, and this potential for water loss exceeds annual precipitation and defines what organisms can live there
Answer:
The biggest factor is that desert biomes don't have to deal with as much rain, and what separates them is how hot or how cold it is.
How does the cell membrane help maintain cell homeostasis? It helps the movement of the station. Regulates cell temperature. Control cell growth. Control what enters and leaves the station.

The cell membrane plays an important role in maintaining homeostasis by controlling substances that enter the cell, enter the cell, or leave the cell. Because the cell membrane is a phospholipid bilayer, it can control the passage of water and ions. (so last)
Describe the structure of the caudal fin of a fish.
answers
The fins are usually the most distinctive features of the fish. They consist of bony spines or rays protruding from the body with skin covering and binding them together, either in the form of a web, as seen in most bony fish, or in the form of a fin, as seen in sharks. . Other than the tail or caudal fin, fish fins have no direct connection to the spine and are only supported by muscles. Its main function is to help the fish to swim. Fins located in different places on the fish serve different purposes, such as moving forward, turning, maintaining an upright position, or stopping. Most fish use fins to swim, flying fish use pectoral fins to glide, and frogfish use them to crawl. The fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef rockfish have spines on their dorsal fins that inject venom, hooks use the first spine of their dorsal fin like a fishing rod to attract them and triggerfish avoid predators by ducking into crevices in corals and using spines on their fins to hold themselves in place.
