Answer:After a few minutes, he noticed a change in the precipitation and saw that the precipitation had changed into ice pellets The falling ice pellets ... The falling ice pellets later changed back to rain, and then the rain stopped and the sun came out.

Explanation:

The stages of the water cycle that relate to the changes in weather that Michael observed are various like evaporation , Condensation, Precipitation which are the various sets like the mentioned.

Evaporation: The sun heats the surface water and causes it to evaporate. This stage is not directly related to Michael's observations, but it is an important part of the water cycle.

Condensation: As water vapor rises into the atmosphere, it cools and condenses into clouds. This stage is also not directly related to Michael's observations, but it sets the stage for the precipitation that follows.

Precipitation: When the conditions in the atmosphere are right, the water droplets in the clouds combine and fall to the ground as precipitation. In Michael's case, the precipitation started as rain and then changed to ice pellets. This change occurred because the temperature in the atmosphere dropped, causing the rain to freeze into ice pellets. The ice pellets eventually melted and turned back into rain.

Runoff: After precipitation falls to the ground, it can either be absorbed into the ground or flow across the surface as runoff. This stage is not directly related to Michael's observations, but it is an important part of the water cycle.

Transpiration: Water that is absorbed by plants is released back into the atmosphere through a process called transpiration. This stage is also not directly related to Michael's observations, but it is an important part of the water cycle.

Overall, Michael's observations demonstrate how changes in temperature and atmospheric conditions can cause precipitation to change from rain to ice pellets and back again. These changes in precipitation can have a significant impact on the weather, as they can affect things like temperature, humidity, and wind patterns.

There is 2 abrasion so I put both

Answer: An abrasion is a type of open wound that's caused by the skin rubbing against a rough surface . It may be called a scrape or a graze. When an abrasion is caused by the skin sliding across hard ground, it may be called road rash.

Answer: Abrasion can happened when the wearing away of rock by sand. Abrasion can also refer to rocks that rub against other rocks.

Answer:

an abrasion is causes by skin contact with a rough or sharp surface. when forceful contact is made (with surfaces like concrete or gravel), the skin tears away.

Explantion:

Ex. When you fall on the ground outside on the asphalt or rocks, you can sometimes "scrape" your knee. this is called abrasion.

Answer:

B

Explanation:

When an animal eats a plant, the energy doesn't change to radiant energy because it's eaten and it isn't living to produce radiant energy.

The steps which shows an incorrect transformation is when an animal eats a plant, chemical energy in the plant changes to radiant energy from the sun. Thus, the correct option will be B.

Energy transformation is also known as energy conversion. It is the process of changing energy from one form to another form. Energy is a quantity which provides the capacity to perform the work or moving in space, or provides heat.

Answer:

water polarity causes cohesion that pulls other water molecules up through a plant.

Explanation:

Water for plants is essential because it constitutes one of the necessary elements so that they can generate their food through the process called photosynthesis.

In effect, plants take the hydrogen from a water molecule and discard the oxygen, providing the atmosphere with this essential gas for life.

Answer:

- Dilation of the pupils

- Increased heart rate (chronotropism) and the force of contraction of the heart  (inotropism), as well as blood pressure.

- Bronchodilation to facilitate the entry of air

- Vasoconstriction in organs that are not needed, such as the abdominal viscera and the kidney

-Vasodilation of muscles, heart, liver and fat tissue

- Hepatic glycogenolysis and lipolysis of adipose tissue

- Increase in blood glucose

Physical stressors; for example cold, hypoglycemia, hemorrhage, hypoxia, necrosis, burn, acute pain are  stimuli that alter the physiological state affecting homeostatic mechanisms, and initiate an adaptive response necessary for survival. For their part, psychological stressors are stimuli that threaten the  current state of the individual or provoke a state of anticipation even though they do not pose an immediate threat  to physiological conditions; need to be processed by the cerebral cortex before initiating the stress response and  they depend largely on previous experiences.

Depending on the type of physical or psychological stress, neurons in the brain stem or those in the areas of the brain are activated.  limbic system respectively, which through axonal projections affect neurons of the nucleus  paraventricular cells of the hypothalamus that synthesize CRH (corticotropin-releasing hormone). Neurons  hypophysiotropic in response to a stimulus, releases CRH to the hypothalamic-pituitary portal circulation that reaches the  adenohypophysis and controls the synthesis and release of adrenocorticotropin (ACTH) that travels through the bloodstream  exerting its feedback mechanism on the adrenal gland. Therefore, the glucocorticoids secreted by the  adrenal gland will exert their actions on peripheral tissues as part of the adaptive response to  stress.

But in addition, the hypothalamus will be in charge of decoding neuronal signals originating in other brain sites and  hormonal signals coming from the periphery. Therefore, hypothalamic neurons not only secrete their  product towards the hypothalamic-pituitary portal blood, but also have nerve projections towards other  brain regions or to nuclei located in the spinal cord (such as the nucleus of the solitary tract) and  controlling the functioning of the autonomic nervous system. Thus the coordinated response to stress includes  adrenaline secretion from the adrenal medulla in response to stimulation of the autonomic system; this hormone  it causes a state of excitement or alertness in the body allowing it to respond to the challenge.

So, the combined action of the hormones cortisol and adrenaline and the autonomic nervous system (system  sympathetic-adrenal) allows a series of vegetative activities involving various apparatus (cardiovascular,  digestive, respiratory, muscular, etc.) and the activation of various metabolic pathways (of carbohydrates and lipids  fundamentally) to provide the immediate energy demands required before the aggressor stimulus or  stress.

Explanation:

During physical exertion or emotional stress, the Sympathetic Nervous System predominates over the Parasympathetic Nervous System. The sympathetic tone favors : intense physical activity for the production of energy in a rapid and prolonged way. The fear, the confusion, the  anger also stimulate the SNS.

The flight or fight reaction is the activation of the SNS on the adrenal medulla produces the release of adrenaline and norepinephrine, which in turn produce the following effects:

- Dilation of the pupils

- Increased heart rate (chronotropism) and the force of contraction of the heart  (inotropism), as well as blood pressure.

- Bronchodilation to facilitate the entry of air

- Vasoconstriction in organs that are not needed, such as the abdominal viscera and the kidney

-Vasodilation of muscles, heart, liver and fat tissue

- Hepatic glycogenolysis and lipolysis of adipose tissue

- Increase in blood glucose

This ensures a self-defense response when perceiving danger, activating a survival instinct
