why cellular respiration and photosynthesis are a
cycle.
Cellular respiration and photosynthesis are referred to as a cycle because the end product of one process serves as the starting material for the next reaction. During cellular respiration, sugar and water are the starting materials, and carbon dioxide and water are the byproducts. Water and carbon dioxide are the starting material for photosynthesis.
ExplanationA cycle is a series of steps that are repeated, which defines this! :)

muscle strains are most often located:
on the surface of the muscle.
under the surface of the muscle.
in the middle section of the muscle.
where the muscle meets the tendon.
Answer:
where the muscle meets the tendon.
Explanation:
I put the answer above and I got it wrong so this is the correct answer!!
:)
Muscle strains are most often located where the muscle meets the tendon. Therefore, the correct option is D.
Stretching or tearing of muscle fibers can occur when a muscle stretches or contracts suddenly or excessively. This often occurs at the musculotendinous junction, where the muscle attaches to the tendon. The area where the tendon meets the muscle is particularly prone to strain, because of the significant stress and tension that occurs there during muscle contractions and movements. Depending on the degree of muscle fiber damage, the intensity of a strain can range from mild to severe.
Therefore, the correct option is D.

Differentiate between positive and negative mass selection.
Answer:
Positive selection involves targeting the desired cell population with an antibody specific to a cell surface marker (CD4, CD8, etc.). ... Negative selection is when several cell types are removed, leaving the cell type of interest untouched.
The left cerebral hemisphere controls the muscles on the right side of the body and vice versa. Which pathway generalization best explains this phenomenon
Given our understanding of neuroanatomy, we can confirm that the left cerebral hemisphere controls the muscles on the right side of the body and vice versa due to the motor decussate of the cortical spinal pathway.
A decussate in regards to the nervous system is described as when the nerve fibers cross from one side of the central nervous system to the other. The decussate in question corresponds to the cortical spinal motor decussate.
The cortical spinal pathway is the nerve pathway that is in charge of muscular control and therefore is the pathway that is responsible for the phenomenon described in the question.

True or False: Because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny.
The statement 'because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny' is TRUE. It is natural selection in action.
According to the evolutionary theory proposed by Darwin, natural selection is the mechanism by which species change (evolve) to adapt to particular environmental conditions.
In this case, the microbiome represents an evolutionary adaptive mechanism, thereby natural selection will tend to favor individuals that have a beneficial microbiome.
In consequence, individuals having a beneficial microbiome will have more chances to reproduce and survive (i.e., they have higher adaptive fitness), thereby they also have more chances to pass this adaptive trait to the next generation.

Generalized global air circulation and precipitation patterns are caused by ________.
A. solar radiation that warms moist air masses near the equator, which then cool and release precipitation as they rise, and then, at high altitude, move north or south of the tropics and sink back to the surface as dry air masses
B. air masses that are dried and heated over continental areas, which then rise, cool aloft, and descend over oceanic areas, followed by a return flow of moist air from ocean to land, delivering high amounts of precipitation to coastal areas
C. polar, cool, moist, high-pressure air masses from the poles that move along the surface, releasing precipitation along the way to the equator, where they are heated and dried
D. solar radiation that warms dry air masses at the poles, causing them to sink toward the tropics, gain moisture, and then release it as precipitation.
Answer:
option B is the right answer
Generalized global air circulation and precipitation patterns are caused by air masses that are dried and heated over continental areas, which then rise, cool aloft, and descend over oceanic areas, followed by a return flow of moist air from ocean to land, delivering high amounts of precipitation to coastal areas. The correct option is B.
What is differential heating?The reason we have different weather patterns, jet streams, deserts, and prevailing winds is due to global atmospheric circulation caused by the rotation of the Earth and the amount of heat received by different parts of the globe.
The earth's polar regions are both cold, owing to the fact that they receive far less solar radiation than the tropics and mid-latitudes.
Air masses that are dried and heated over continental areas cause generalized global air circulation and precipitation patterns.
This is then rise, cool aloft, as well as descend over oceanic areas, accompanied by a return flow of humid air from ocean to land, achieving higher amounts of precipitation to coastal areas.
Thus, the correct option is B.

An individual with androgen insensitivity syndrome will:
A. Not be feminized at puberty
B. Prefer a female sexual partner
C. Not function sexually as an adult
D. Have female external genitalia
Answer:
D I think. i am not completely sure.
An individual with androgen insensitivity syndrome will have female external genitalia, which is option D, as androgen insensitivity syndrome (AIS) is a genetic condition in which an individual's cells are unable to respond to androgens.
What is androgen insensitivity syndrome?Androgen insensitivity syndrome (AIS) is a genetic disorder in which an individual's body is unable to respond properly to male sex hormones, called androgens. The condition is caused by mutations in the gene that codes for the androgen receptor, which is a protein that binds to androgens and enables them to activate certain genes. In individuals with AIS, the androgen receptor either doesn't work at all or doesn't work properly, which leads to a range of physical changes that can vary in severity depending on the degree of androgen insensitivity.
Hence, An individual with androgen insensitivity syndrome will have female external genitalia, which is option D.

Causal attribution theories generally try to explain how we:
1) are influenced by others
2) predict how others will behave based on their attitudes
3) change our attitudes toward other people
4) determine the causes of others' behavior
5) relate to and interact with other people
Causal attribution theories generally try to explain how we determine the causes of the others' behavior based on personal or situational attributions.
This theory was developed by Horald Kelly in 1967, and explains how people attribute the behavior of others according to dispositional (internal) and situational (external) factors.
Dispositional factors are those based on internal characteristics, such as effort and skill. Situational factors, on the other hand, are environmental and external to the individual, such as luck and task difficulty.
Therefore, according to theory we are more likely to attribute the cause of the behavior of others to factors that most coincide with the action.
