Metabolic rate of alcohol is unaffected by exercise TRUE.
The basal metabolic rate (BMR) calculates the bare minimum of calories required for a person to maintain their essential bodily functions over the course of a 24-hour period of rest. Such processes include breathing as an example. circulation. digestion as well as nutrient absorption
The three elements that make up the metabolic rate are the baseline metabolic rate, the energy expended during physical activity, as well as the thermic effect with food.
Alcohol reduced shivering metabolic rate by an overall mean of 13%, insufficient to affect cooling rate.

Epithelial cells of kidney tubules may have many microvilli. what is the reason for the microvilli?
To expand the surface area of the tubule and maximize the reabsorption of vital chemicals, the cells lining the proximal convoluted tubule develop microvilli. Microvilli are hair-like protrusions that come from a cell's nucleus.
Reabsorption- Water and other solutes are reabsorbed as they return from the tubule to the plasma. Over the whole length of the renal tubule, various amounts of water and particular solutes are reabsorbed.
Proximal Convoluted Tubule (PCT)- Between Bowman's capsule and the loop of Henle, the proximal convoluted part of the vertebrate nephron plays a key role in the resorption of water, sodium, and chloride ions, and sugar from the glomerular filtrate.

c. bone marrow.
d. kidneys.

Stem cells that will form t lymphocytes mature in the stem cells that will form t lymphocytes mature in the Thymus.
T cells proliferate and differentiate into memory T cells, helper, regulatory, or cytotoxic T cells in the thymus. After that, they are planted into perivascular tissues or moved around by the lymphatic or blood systems.
Thymus, pyramidal lymphoid organ located just below the sternum at the level of the heart in humans. The organ is called the thymus because its shape resembles that of a thyme leaf.
The organ is composed mainly of two types of cells called respectively lymphocytes and reticular cells. The reticular cells form a loose network like in a lymph node, while the spaces between them are filled with lymphocytes. The cortex, characterized by its high concentration of lymphocytes, is the site of intense lymphocyte proliferation. Lymphocyte proliferation in the thymus is evenly distributed throughout the cortex and not in the germinal centers as is the case in other lymphoid tissues. Some of the daughter cells - called T cells (derived from the thymus) - produced in the cortex migrate to the marrow, where they enter the bloodstream through the medullary veins and join the lymphocytes in the peripheral blood and lymphoid organs.

A bag contains 6 clear marbles and 4 red marbles one marble is drawn from the bag and replaced a second marble is drawn from the bag and replaced what is the probability of getting a clear marble the first time and a red marble the second time
Answer:
4/25
Explanation:
bag contains 6 clear marbles and 4 red marbles = 6+4=10
chance of red marble = 4/10
4/10=2/5
Now, probability of getting a red marble the first time AND a red marble the second time = (2/5) x (2/5)=4/25
When individuals' genes may systematically relate to the types of environments they are exposed to, it is called?
When individuals' genes may systematically relate to the types of environments they are exposed to, it is called heredity-environment correlations.
Gene is the basic unit of inheritance. It encodes the information for any trait that is expressed by means of formation of proteins. Each gene can have its two or more alternative forms that are called allele. These alternative forms are the result of mutations.
Heredity-environment correlation is the effect on a gene due to hereditary and environmental factors and the result that emerges out of it. These correlations can have three mechanisms: (a) Passive gene-environment correlation; (b) Evocative (or reactive) gene–environment correlation; and (c) Active gene–environment correlation.

There are 8 pairs of cervical spinal nerves, but only 7 cervical vertebrae, because the first cervical pair emerges between the ______ and the ______.
The first cervical pair emerges between the base of the skull and the neck (thoracic vertebrae).
The cervical spine is the neck region of the spine and is made up of eight cervical spinal neurons and seven stacked bones called vertebrae. Your cervical spine's first two vertebrae are distinct in both form and function. The atlas, which is the first vertebra (C1), is a ring-shaped bone that starts at the base of your skull. Your head is held upright by the atlas. The atlas can pivot against the second vertebra (C2), which is referred to as the axis, allowing for the side-to-side "no" rotation of your head. Facet joints, which connect the seven cervical vertebrae (C1 to C7) at the rear of the bone, allow your neck to move forward, backward, and in a twisted position. According to their order from superior (C1, or the first cervical vertebra), to inferior, each cervical vertebra is given a name (C7 or seventh cervical vertebra).

Two evolutionary processes that may produce a cline in a human allele or trait are gene flow and genetic drift.
What is genetic Drift?
Genetic drift is the arbitrary change in the population's frequency of a gene variant that already exists. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Additionally, it can make previously uncommon alleles far more common and even fixed.
What is gene flow?
The phrase "gene flow" refers to the processes through which genes are transferred from one group to another. Gene flow in anthropology more broadly refers to allelic change brought on by people moving from one place to another.
Hence, in both the cases the allelic frequency is changed and thus with the mutation and natural selection new clines can be formed.
