Function of protein is to help maintain fluid distribution within the body by Attracting water into compartments where it is needed.
Protein function by attracting water into the compartments with the help of Aquaporins.
Aquaporins regulate the flow of water into and out of the cells. For the proteins that float freely in a cell, the attraction is dependent on the arrangement of water molecules.
Aquaporins are integral membrane proteins serving as a channel for water transfer. They are present in the biological membranes. They form water channels and allows movement of water.
Proteins are water loving i.e. hydrophilic.

The coleman report and other studies have found that ______ is the most powerful factor in determining students' level of school achievement.
The Coleman report and other studies have found that neighborhood and peer environment is the most powerful factor in determining students' level of school achievement.
The Civil Rights Act of 1964 required the publication of the Coleman Report. The law assigned the U.S. Office of Education two years to write a report that would analyze the disparities in educational opportunities for elementary and secondary education across the country.Black and white schools have roughly equal access to regional resources. However, the researchers came to the conclusion from the research that neither the school's infrastructure nor its resources were the most crucial indicators of a child's academic achievement. Instead the Home life and neighborhood played an important role. Six community elements have been identified by study as influencing student achievement: financial situation, environment, educational level, communication with and support provided to schools, availability of community child care, and community cohesion (i.e., quality of education).learn more about Coleman report here: https://brainly.com/question/5778843

Between 1994 and 1997, 70 Addax were released into fenced sections of protected areas in Tunisia and Morocco. By
2003, their numbers had increased to about 200. This is an example of
OA. Ex situ conservation
OB. Coppicing
OC. Habitat management
D. In situ conservation
It is an example of Ex situ conservation. The correct option is A.
What is ex-situ conservation?It is a method of conserving biodiversities outside their natural habitats.
Ex situ conservation is in direct contrast to in situ conservation. This means that in in-situ conservation, biodiversities are conserved in their natural habitats.
In the illustration, the Addax were released into fenced sections of protected areas in two countries.
The fenced section means that the Addax were not allowed to roam freely as they would in their natural habitats. The fenced section means that their movement is limited as compared to natural habitats.
Thus, the Addax were being conserved ex-situ.

When a person overdoses on drugs, ultimately, what brain structure was shut down to produce death?
A Final statement or concluding statement
'Medulla' shuts downs as a result of drug overdose.
Why shutting down of Medulla results in death?Usually, medulla damage results in death. Additionally, morphine (and other opiate medications), cocaine, and amphetamine have a very strong effect on this region. Through the impairment of cardiovascular function, these medicines have the potential to result in drug overdose. The development of apnea and a lessened respiratory response to hypoxia are both brought on by receptors, which also produce a medullary diminished response to hypercarbia.

For generating nuclear energy, fusion experiments use the smallest nuclei, isotopes of hydrogen, while fission experiments use very large nuclei. why?
Energy is released whenever a nucleus changes: However, it is more difficult to cause fission by striking smaller atoms with neutrons. Large atoms are also more difficult to join by pressing them together.
Even little atoms must currently be accelerated to extremely high speeds for fusion.Fission literally translates to "a splitting or breaking up into bits." Atoms are split during nuclear fission to release heat energy.A large, somewhat unstable isotope (atoms with the same number of protons but differing numbers of neutrons) undergoes nuclear fission when it is struck by fast particles, often neutrons. The unstable isotope is struck by these accelerated neutrons, causing it to fission, or split into smaller particles.Nuclear reactions like fission and fusion both provide energy, but they have different uses.learn more about fission here: https://brainly.com/question/3992688

Blood passes through the left av valve as it moves from the _______ to the _______.
Answer:

Blood passes through the left AV valve as it moves from the left atrium to the left ventricle.
The left AV valve is also known as the mitral valve or bicuspid valve. It is located between the left atrium and the left ventricle in the heart and allows blood to flow from the left atrium, where it has been collected from the lungs, into the left ventricle, from where it is pumped out to the rest of the body during the contraction of the heart.
Blood is a vital bodily fluid that circulates through the circulatory system of animals, including humans.

Why does strength and contrcation increase somwhat after a few stimulation/contraction events?
The muscle generates stress during the contraction phase, which is accompanied by the cycling of the cross bridges. During the relaxation phase, the muscle lengthens back to normal.
All of the muscle fibers connected to that motor neuron will contract as an action potential moves down the motor neuron. A muscle twitch is the contraction caused by a single action potential. A single muscle twitch consists of three parts. the contraction phase, the relaxation phase, and the latent period, often known as the lag phase. The action potential reaches the muscle, and the latent period is the brief (1-2 msec) interval before tension is seen in the muscle. This period of time is necessary for calcium to diffuse out of the SR, bind to troponin, transfer tropomyosin away from the active sites, build cross bridges, and pick up any slack in the system.learn more about contraction phase here: https://brainly.com/question/26765109

How does 1 act human after being in isolation for years.
Answer:
the behaviour is disturbed
Explanation:
One of the reasons that living in isolation is difficult is because humans are social creatures. Many people that have lived in isolated environments – such as researchers stationed in Antarctica – report that loneliness can be the most difficult part of the job. Yossi Ghinsberg, an Israeli adventurer and author who survived weeks alone in the Amazon, said that loneliness was what he suffered from most and that he had created imaginary friends to keep himself company.
Loneliness can be damaging to both our mental and physical health. Socially isolated people are less able to deal with stressful situations. They’re also more likely to feel depressed and may have problems processing information. This in turn can lead to difficulties with decision-making and memory storage and recall.
People who are lonely are also more susceptible to illness. Researchers found that a lonely person’s immune system responds differently to fighting viruses, making them more likely to develop an illness.
What is the anticodon sequence of a nonsense suppressor mutant trna that can suppress more than one stop codon?
The anticodon s a sequence of a nonsense suppressor mutant trna that can suppress more than one stop codon
An anticodon is a trinucleotide sequence that is complementary to a matching codon in a messenger RNA (mRNA) sequence and is found at one end of a transfer RNA (tRNA) molecule. UAC serves as the drug's antagonist. The ribosome is where tRNA and mRNA link to recognize codons. Trinucleotide units called anticodon are found in tRNA. To the codons in mRNA, it is complementary.
Codons help the ribosomes, which are responsible for protein synthesis, receive genetic information from the nucleus. The tRNA molecules have anticodons. During translation, they serve the purpose of forming a base pair with the codon on a strand of mRNA. By doing this, the expanding polypeptide chain will be joined to the right amino acid.

The correct answer is 'association of blood and interstitial fluid.'
The cardiovascular system is made up of the heart, blood vessels, and blood. Its primary function is to transport nutrient- and oxygen-rich blood to all parts of the body while returning deoxygenated blood to the lungs. Abnormalities or damage to any one or all of the cardiovascular system's components may result in serious health problems. Common diseases that can affect the cardiovascular system include coronary artery disease, heart attacks, excessive blood pressure, and stroke.
