Capillaries pass oxygen and waste between blood and cells.
Red blood cells fight disease.
People with type O blood can receive AB blood donations.
The left ventricle controls the heartbeat.
Answer: Capillaries pass oxygen and waste between blood and cells.
Explanation: Capillaries are very thin-walled tubes that connect the arteries to the veins. The walls of these tubes are only one cell thick. Capillaries are found everywhere in the body. These thin tubes allow the food, oxygen, and waste to move between the bloodstream and cells. Waste products pass into capillaries and are carried by the veins to be disposed of in other parts of the body. Capillaries are the only blood vessels thin enough for materials to pass back and forth between cells and blood.
Blood Capillaries pass oxygen and waste between blood and cells. Thus option A is correct.
What are the function of blood capillaries?Capillaries are small type of blood vessels where a single red blood cell can barely fit in them.
They involve in the connection of arteries and veins, facilitate the exchange of certain elements between blood and tissues.
They involve in exchange of oxygen, nutrients, and waste between blood and tissues by two major process called passive diffusion and pinocytosis.
In passive diffusion the movement of a substance from the region of higher concentration to the region of lower concentration occur.
In Pinocytosis, intake of small molecules by the cell of the body like fats and proteins.
The capillaries wall are composed up of endothelium which is a thin cell layer called and surrounded by another thin layer called a basement membrane.
Thus option A is correct.

Explanation:
Humans are unusual because our cultural practices can actually change our environmental circumstances. We can change the environment in which natural selection acts on our traits. Describe how this process has played out in the evolution of adult lactose tolerance. Describe how this process has played out in the maintenance of the sickle-cell trait. Can you hypothesize any similar situations where our future evolution may be influenced by cultural practices we have today
Answer:
Adult humans capable of digesting lactose were selected, thereby this phenotypic trait became common in dairy consuming societies
Explanation:
From the first moment after birth, babies can digest lactose in milk because they produce lactase, which is an enzyme capable of hydrolyzing lactose into glucose and galactose. In human societies that non consume milk products, the level of the lactase enzyme abruptly decreases during the first years of life due to the inactivation of the gene encoding this enzyme (i.e., lactase gene). However, in dairy consuming societies, a genetic mutation in the lactase gene that appeared among early cattle-raising people in Europe was selected, nowadays, this mutation is mostly present (i.e., in a higher frequency) in these societies, thereby adult people is generally adapted to consume lactose-based products.

Water would be considered an actual renewable resource and actual nonrenewable resource. Thus, option C is correct.
Why water is considered as actual renewable?Water would be considered an actual renewable. A renewable resource is a resource which can be used repeatedly and replaced naturally. Examples include oxygen, fresh water, solar energy and biomass. New resources may include goods or commodities such as wood, paper and leather.
Non renewable energy comes from sources that will run out or will not be replenished in our lifetimes-or even in many, many lifetimes. Non renewable energy sources are fossil fuels: coal, petroleum, and natural gas.
Potential renewable resource, potential nonrenewable resource, and actual renewable resource and actual nonrenewable resource. Water would be considered an actual renewable.
Therefore, Water would be considered an actual renewable resource and actual nonrenewable resource. Thus, option C is correct.

Are seasonal responses in plants triggered by temperature or by length of daylight
Answer:
Plants don't have sensation of time, at least that we know till now. However plants have different stimuli against the different environmental change i.e lack of water causing yellow and fall of leaves. Such seasonal responses are reaction to environmental changes rather than timeline.

Explanation:
In most cases, mutations in the core of a protein that replace a smaller nonpolar side chain in the wild-type (e.g., Ala, Val) with a larger nonpolar side chain (e.g., Leu, Ile, Phe, Trp) in the mutant, result in significant destabilization and misfolding of the mutant. What feature of the protein core explains this observation? Why would such a mutation prevent a protein from folding properly? Match the items in the left column to the appropriate blanks in the sentences on the right.
Explanation:
we are required to fill in the blank spaces in the attachment.
protein side chains are non polar. so the first answer is non polar. These side chains are hydrophobic in nature. so the second blank is hydrophobic. Non polar substances are known to have large number of van der waal forces. the third answer is large and the fourth is vanderwaals contact. the protein core destabilizes only when there is a weakening of vanderwaals contact which brings about mutation.
dear user your answer should look like this:
Interactions of non polar side chains in protein sequence lead to the formation of a tightly packed hydrophobic core. This core is stabilized by a large number of vanderwaals contact. When a mutation occurs, it destabilizes the protein core and weakens vanderwaals contact leading to misfolding

B Cells contain DNA, which controls the production of proteins.
C Proteins combine to produce cells, which produce DNA.
D DNA is made up of proteins, which tell a cell how to function.
Answer: cells contain DNA, which controls the production of proteins
Explanation:
The statement best describes the relationship that exists among proteins, DNA, and cells - B. Cells contain DNA, which controls the production of proteins.
A cell contains DNA that produces proteins
A cell has many substances and organelles present in it, that all have specific functions in the cell. DNA is the hereditary unit of the cell that contains genetic information about growth, development, and reproduction.
DNA helps in synthesizing protein by a two-step process called protein synthesis. The first step called transcription involves copying the instruction from DNA into an mRNA sequence and the second is producing an aminoacid chain by translating the mRNA sequence.
