Amino acids that must be obtained from foods in order for the body to function properly are called?
Amino acids that must be obtained from foods in order for the body to function properly are called essential amino acids.
The body is unable to produce essential amino acids. They must therefore originate from food. Organic substances known as amino acids are primarily made up of nitrogen, carbon, hydrogen, and oxygen.Twenty distinct amino acids are required by your body for growth and optimal operation. Despite the fact that all 20 of these are crucial for your health, just nine are considered essential.These include valine, tryptophan, isoleucine, leucine, lysine, methionine, phenylalanine, and threonine.While your body may produce non-essential amino acids, it is unable to produce essential amino acids; therefore, you must obtain them through diet.Animal proteins including meat, eggs, and poultry are the richest providers of necessary amino acids.But some plant meals, such edamame and tofu made from soy, do contain all nine essential amino acids. They are "complete" sources of protein.

A woman who is heterozygous for the x-linked, recessive hemophilia allele mates with a man who does not have hemophilia. which of the possible offspring will have hemophilia?
If a mother is heterozygous (a carrier) for hemophilia and the father does not have hemophilia, each son has a 1 in 2 (50%) chance of getting his mother's hemophilia allele and having hemophilia. Each daughter has 1 in 2 (50%) chance of getting her mother's hemophilia allele and being heterozygous.
If one female is heterozygous for the hemophilia trait and is considered a carrier. One male receives a damaged X-chromosome and inherits the condition known as hemophilia. If a man does not have hemophilia, he will have a non-hemophilia allele on his X chromosome which in this case would be "H". The mans genotype would be "XHY". Man with hemophilia will have XhY genotype since it is an recessive disorder .

Why is the nitrogen cycle important?
Answer:
It's very important because it helps in converting inert nitrogen gas into a usable form for the plants through the biochemical process. In the process of ammonification, the bacteria help in decomposing the animal and plant matter, which indirectly helps to clean up the environment.
Explanation:
Answer:
The nitrogen cycle is a biogeochemical process in which nitrogen, in various forms, is circulated from the atmosphere to the living organisms and later back to the atmosphere. Living organisms require nitrogen for the synthesis of nucleic acid and proteins. The atmosphere contains almost 78% of the nitrogen in an inert form (N2). Living organisms cannot use this nitrogen unless it is converted to ammonia, nitrates, and other usable compounds of nitrogen.
The nitrogen cycle is a cyclic process where the nitrogen travels from the inorganic form in the atmosphere to the organic way in the living organisms. The nitrogen cycle contains several steps, including nitrogen fixation, assimilation, ammonification, nitrification, and denitrification. This cycle is essential in maintaining a proper ecological balance and is present in both marine and terrestrial ecosystems.

The group of vascular disorders that are marked by blood vessel necrosis and inflammatory injury is the:________
The group of vascular disorders that are marked by blood vessel necrosis and inflammatory injury is Cutaneous necrotizing vasculitis.
Vasculitis involves inflammation of the blood vessels. The inflammation can cause the walls of the blood vessels to thicken, which reduces the width of the passageway through the vessel. If blood flow is restricted, it can result in organ and tissue damage. There are many types of vasculitis, and most of them are rare.
Cutaneous necrotizing vasculitis is a not uncommon disorder characterized by an inflammation of the blood vessel walls and skin lesions. These skin lesions may be flat and red (macules), nodules, or more substantial hemorrhages under the skin (purpura).
Colchicine, hydroxychloroquine, dapsone, or a short course of low-dose corticosteroids can be tried. Sometimes, stronger immunosuppressants (eg, azathioprine, methotrexate) are used, particularly if lesions ulcerate or if corticosteroids must be taken indefinitely to control symptoms.

A dendrite is a neuron whose physical part plays a role similar to that of the wide receiver in football
The finger-like cells called dendrites are found on the terminal of a neuron. They are tiny, branching fibers that protrude from the nerve cell's cell body. This fiber expands the area that can be used to receive incoming data. The receiving or input parts of a neuron are called dendrites.
Appendages called dendrites are made to receive signals from neighboring cells. They take the form of projections with a tree-like structure that are triggered by other neurons and carry the electrochemical charge to the cell body (or, more rarely, directly to the axons). These little protrusions relay electrical stimulation to the soma and take in information from neighboring neurons. Synapses also cover the dendrites.

The movement of ions across the cell membrane is needed to accomplish repolarization. what cell structure is used to prepare for depolarization?
The movement of ions across the cell membrane is needed to accomplish repolarization while sodium-potassium pump is used to prepare for depolarization.
The sodium-potassium pump is an active transport system that transports potassium ions into cells and sodium ions out of cells. Using energy from ATP and carrier proteins in the cell membrane, the sodium-potassium pump transports both ions from lower to greater concentration regions. More specific details about the sodium-potassium pump's operation are shown in the Figure. The main ions in both the fluid inside cells and the fluid surrounding them are sodium and potassium, respectively. The resting potential is an electrical gradient that results from these concentration changes across the cell membrane.

D) saturated. E) hypertonic.
Initially, in terms of tonicity, the solution in side A with respect to that in side B is isotonic.
A solution is considered to be isotonic if it possesses the same osmolarity, or level of solute concentration, as another solution. When these two solutions are placed on either side of a membrane that is only partially permeable to water, water will flow in an equal amount from one solution into the other. The result is that there is no water flow at all between the two solutions, despite the fact that water is travelling in both directions.A solution is considered hypotonic when it has a lower level of solute concentration in comparison to another solution.A solution is considered hypertonic when it has higher osmolarity compared to another solution.
