The brain is a network of interconnecting neurons that control and integrate the body's activities. components make up these neurons are Cell body, Axon, Dendrite
Nerve cells or neurons
Tang is no less important part of the anatomy of the nervous system is the nerve cell itself or called a neuron. The function of a nerve cell or neuron is to transmit nerve impulses.
Based on their function, neurons are divided into three types, namely sensory neurons that carry messages to the central nervous system, motor neurons that carry messages from the central nervous system, and interneurons that transmit messages between sensory and motor neurons in the central nervous system.
Each neuron or nerve cell consists of three parts or basic structures. The anatomy of these neurons, namely:
- The cell body, which has a nucleus.
- Dendrites, which are shaped like branches and function to receive stimuli and carry impulses to the cell body.
- The axon is the part of the nerve cell that carries impulses away from the cell body. Axons are generally surrounded by myelin, which is a dense, fatty layer that protects nerves and helps messages pass. In peripheral nerves, this myelin is produced by Schwann cells.
These nerve cells can be found throughout the body and communicate with each other to produce physical responses and actions. According to the National Institutes of Health, there are an estimated 100 billion neurons in the brain. These nerve cells include 12 pairs of cranial nerves, 31 pairs of spinal nerves, and elsewhere.
Nervous system function
In general, the nervous system in humans has several functions. The functions are:
- Collects information from inside and outside the body (sensory function).
- Sends information to the brain and spinal cord.
- Processing information in the brain and spinal cord (integration function).
- Sends information to muscles, glands, and organs so they can respond appropriately (motor function).

some viral genomes, composed of positive sense single-stranded rna, act as mrna. what advantage might these viruses have over other kinds of viruses?
Because they don't require being changed from DNA to RNA, those viruses DO NOT require travelling to the nucleus.
Why are RNA viruses beneficial?Studying the rates of mutation in RNA viruses is one of the more fascinating biological topics. So that their mutation rates can be maximised for fitness, they encode the replication machinery (in comparison to small DNA viruses that use the polymerases of their host cells).
As opposed to DNA, why do viruses employ RNA?The transcription step can be skipped by RNA viruses, unlike DNA viruses that must always convert viral DNA into RNA in order to create proteins. Additionally, some RNA molecules have the ability to operate as messenger RNA that is translated directly into protein.

contraction of which muscle normally accounts for around 75% of the air movement in normal quiet breathing?
The contraction of diaphragm normally account for around 75% of the air movement in normal quiet breathing.
This outward push is increased by the inspiratory muscles (mainly the diaphragm and external intercostals) during inspiration. This causes the lung tissue to expand and air to enter the alveoli at a rate regulated by airway resistance.
The so-called "silent" expiration is caused by the elastic recoil of the lung parenchyma, which causes these inspiratory muscles to relax and the lung to regain its equilibrium volume.
However, in forced expiration, the abdominal and internal intercostal muscles are employed to exert more force against the lungs, causing them to expel air more quickly and allowing expiration down to the residual volume (RV).
Lung function testing is performed to quantify these changes. In lung disease, these forces are altered.

Drugs referred to as GnRH agonists or antagonists are used to stop ovulation. This stops ovulation and the release of a particular hormone. Luteinizing hormone is the hormone whose secretion is prevented.
Drugs called gonadotropin-releasing hormone (GnRH) agonists are used to treat adult women's endometriosis symptoms and prevent children from developing central precocious puberty.
The growth and operation of the sexual organs are significantly influenced by LH. Luteinizing hormone helps women manage their menstrual cycles. Additionally, it causes an egg to be released from the ovary. This is the ovulation process.
Low levels of LH could indicate stress, anorexia, malnutrition, or pituitary disease. If you are a male, abnormally high LH levels and low levels of testosterone may indicate that your testicles are not producing enough testosterone in response to the signal from LH.

studies of rough-skinned newts have documented their ability to produce toxins in defense against a predator attack. the common garter snake, a predator of rough-skinned newts, exhibits a resistance to the toxin produced by the newt. in response, newts have been observed to produce increasingly potent toxins, which in turn results in selection for snakes with even greater resistance to the toxin. what phrase best describes this interaction between rough-skinned newts and garter snakes? group of answer choices host-parasite coevolution obligate mutualism evolutionary arms race diffuse coevolution
Evolutionary arms race best describes the interaction between rough-skinned newts which have the ability to produce toxins against their predator garter snakes.
What is an evolutionary arms race?
It is an ongoing struggle between competing sets of co-evolving genes, and phenotypic and behavioral traits that develop escalating adaptations and counter-adaptations against each other.
One example is the arms race between bats and moths. In this, the weaponry used by each is largely based on sound and hearing.
In the above case, rough-skinned newts are compared to the host and the common garter snake is compared to a parasite. Rough-skinned newts produce toxins in defense against a predator (common garter snake). This predator exhibits resistance to the toxin produced by the newt. in this way, if the newt increased potent toxins then a common garter snake too increases its resistance to the toxin. Common garter snakes exhibit an evolutionary arms race by evolving rough-skinned newts.
Let us discuss other options
Mutualism is a relationship between two organisms each benefiting from the relationship.Host-parasite coevolution is a special case of coevolution where a host and a parasite continually adapt to each other.Diffuse coevolution also called guild coevolution where whole groups of species interact with other groups of species leading to changes that cannot really be identified.Hence rough-skinned newts and common garter snakes exhibit an evolutionary arms race.

By laying eggs to reproduce, sea turtles are considered to be Oviparous.
An oviparous creature is one that produces eggs, and the youthful hatch after being ousted from the body. Whereas fertilization of the egg can happen inside or remotely, oviparous creatures continuously hatch the youthful outside of their body. Numerous creatures of land and water, winged creatures, fish, and reptiles are oviparous and regularly make homes to secure their eggs. This could be differentiated from ovoviviparous creatures, which hatch eggs interior of their bodies, at that point remove live young. This will be seen in a few sharks, snakes, and other animals. Being oviparous is a developmental procedure for generations. In this strategy, one or numerous eggs can be delivered. Each egg could be a gamete that has the female’s commitment to the hereditary material. In numerous species, the male supplies his gamete in the shape of sperm, which must discover its way to the egg. Once fertilized, the cells inside the egg will start to subdivide as a fetus is shaped
