Answer:
The parasympathetic nervous system is repressed during your escape.
Explanation:
In the exposed example, during your escape from the lion, the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) system are responsible for your body response. They send signals and release adrenaline and noradrenaline to increase your heart biting frequency, and blood pressure, stimulating your respiration and dilating your respiratory tracts.
Once you manage to escape from the lion, and the threat factor is over, the body gets back to normality. At this point, the parasympathetic nervous system is activated. Your body activities become normal again. Your arterial pressure, respiratory frequency, and cardiac frequency get reduced to their normal conditions. You are relaxed and at rest.
When the parasympathetic system is activated, the sympathetic nervous system is not, as they perform in opposite ways.

Which statement best describes the effect on water transport across the cell membrane if the aquaporin in the figure ceases to function?
Answer:
Water molecules will still be able to move across the cell membrane but at a slower rate.
Explanation:
D isn’t a sensible answer because Aquaporin is a protein with a role to regulate water transport. In its absence, of course there will be defects. And A is impossible due to the existence of active transport. (I also looked it up) (:
Answer:
Water molecules will still be able to move across the cell membrane but at a slower rate.
Explanation:
The aquaporin facilitates water passage, but water can still move across the membrane by osmosis. (osmosis requires no channel protein, but aquaporin makes diffusion faster).

What is the MAIN type of energy that is produced during cellular respiration?
Glucose
O ATP- Adenine Triphosphate
O Water
Light
Answer:
ATP- Adenine Triphosphate
Explanation
:In cellular respiration, energy is obtained by oxidizing an organic molecule, usually glucose, releasing energy. Part of that energy is stored as ATP (adenosine triphosphate) molecules, and part is released as heat.

Match each tool with its influence on science
Answer:
xray - allows scientists to see dense structures
Microscope - view things that cannot be seen with the naked eye
Telescope - stars, planets and black holes
Ultrasound - see inside the body in real time
Explanation:
Xrays shows highlights dense structures within the body (bones). But is not in real time, usually there images that are captured and reviews later.
Microscope - the clue is in the name, think micro= tiny! Therefore cant be seen by the naked eye. The "scope" part of the word means to look at or observe. So put them together and you get to look at or observe tiny things.
Telescope - the first part of this word "tele", means something far away or at distance. Which gives a clue at what it does, add on the "scope" meaning of to look at or observe and you get; to look at or observe something that is far away.
Ultrasound - this is what is used to monitor the health of babies when they're still developing. It can be seen in real time.
X-rays enable researchers to observe dense formations. View objects using a microscope that is invisible to the eye. Telescope: black holes, planets, and stars see into the body in real-time using ultrasound.
What is the tool microscope's influence on science?X-rays depict the body's dense internal architecture (bones). But it's not in real-time, typically, pictures are taken and then looked at afterward.
The name of the instrument, "microscope," gives it away—think small! as a result, not visible to the eye. The word "telescope" refers to anything far out or remote in its first half.
When a baby is still developing, their health is monitored using ultrasound technology.
Therefore, view objects using a microscope that is invisible to the eye.

A snake catches and eats a small field mouse. Later that day, a hawk catches the snake and eats it. Which three terms describe the snake? consumer, predator, prey parasite, predator, producer predator, producer, consumer prey, parasite, producer
Answer:
Consumer, predator, and prey.
Explanation:
The snake is a consumer and a predator because it eats or consumes another organism (the mouse), but it is also prey because it is consumed or preyed upon by another predator (the hawk).
The three terms that best describe the snake are consumer, predator, and prey. Thus, the correct option for this question is A.
What is Predator?A predator may be characterized as a type of animal that significantly obtains food by killing and consuming other organisms in the form of food and taking energy for the metabolic processes. These animals hunt and kill other organisms for food. The organisms that are consumed by the predators are known as the prey.
According to the context of this question, when a snake eats a mouse, it is called a consumer and predator because it actually drives energy from the mouse in order to facilitate its metabolic processes. When a hawk when catches a snake and eats it, it is often known as prey, and the hawk is known as a predator in this case.
Therefore, the three terms that best describe the snake are consumer, predator, and prey. Thus, the correct option for this question is A.

Select all of the arrows in the model that represent the movement of nitrogen from an abiotic system to a biotic system.
Answer:
Nitrogen compounds in the soil ---> Plants
Nitrogen compounds in the soil ---> Denitrification bacteria (convert nitrogen compounds to N2)
Nitrogen in the atmosphere ---> Nitrogen fixing bacteria (convert N2 to nitrogen compounds)
Explanation:
This model in the image section is portraying the nitrogen cycle, which involves the transfer of nitrogen within biosphere, atmosphere, and lithosphere etc. The abiotic components of this model are the non-living parts while the biotic components are the living parts.
In this model, the movement of nitrogen from abiotic or non-living component of an ecosystem to the biotic or living component is as follows:
Nitrogen compounds in the soil ---> Plants
Nitrogen compounds in the soil ---> Denitrification bacteria (convert nitrogen compounds to N2)
Nitrogen in the atmosphere ---> Nitrogen fixing bacteria (convert N2 to nitrogen compounds)

C.

Answer:
Explanation:
Photosynthesis Takes Place in Chloroplasts. ... The inner membrane surrounds a stroma, which is the site of the carbon chemistry of photosynthesis
sorry if im wrong
Photosynthesis occurs in chloroplast thylakoid membranes. Electron transport chains produce ATP and NADPH. Therefore, option (A) is correct.
What are chloroplasts?Chloroplasts are plastids that are made up of an outer membrane, an inner membrane, grana, and the stroma. These four components make up the chloroplast. The inner membrane encloses a region that is filled with fluid and is known as the stroma. This region includes enzymes that are responsible for light-independent processes that occur during photosynthesis. When this inner membrane is folded inward, it creates linked stacks of disk-like sacs known as thylakoids. These thylakoids are frequently grouped in stacks that are called grana.
The chemical reaction known as photosynthesis, which converts sugar and oxygen from carbon dioxide and sunlight, takes place in chloroplasts, which are found in plant cells.
