Answer:
Change of temperature
Explanation:
The independent variable is what you change and the dependent variable is what changes because of what you change.
If you have 2 cookies you will have only 1-2 people if you have 200 cookies you would have more people. The independent would be how many cookies you have and the dependent variable would be how many people come.
It creates high blood pressure because your body is trying to remove it the best it can and decreased blood flow because your body does not want that blood going bad of that makes sense.
Answer:
Rabbits are adapted to a certain type of environment and conditions, not certainly winter. So this effect the survival rate of the rabbits.
Moreover, their diet intake may be affected, for example, they are herbivores, so the plants they consume might not be present in this harsh season.
Then, competition with other animals increases as well, so the rabbits might have more predators.
Answer:
Answer is option D.
The sun's energy is transferred through the vacuum of space to Earth by radiation.
Explanation:
The three forms of heat transfer are conduction, convection and radiation. The process of heat transfer between two solid objects in contact with one another due to a temperature difference is known as conduction. An ice cube melts while you hold it in your hand, is an example of conduction. Here, the heat energy from the hand is transferred to the ice cube and the ice melts.
Convection is the heat transfer occurs in moving materials (liquid or gas) due to the temperature difference between two regions. Hot soup rises to the top of the bowl, while cooler soup sinks to the bottom is an example of convection. The hot soup is less dense than cold soup, so it rises to the top and the cold soup at the top sinks to the bottom.
Radiation is a form of heat transfer where the heat energy is transferred through electromagnetic waves like infrared, UV rays etc. The sun's energy is transferred through the vacuum of space to Earth by radiation. Heat energy is transferred through vacuum by infrared radiation emitted by the Sun. The Earth absorbs it and turns the energy into heat.
Answer:
Renin; angiotensin I and angiotensin II
Explanation:
Renin is a key hormone involved in the renin-angiotensin-aldosterone system (RAAS), which is responsible for regulating blood pressure in response to changes in blood volume. Renin is secreted primarily by the kidneys to promote the production of the peptide hormone angiotensin in the blood vessels. Subsequently, angiotensin stimulates the release of aldosterone from the adrenal cortex, stimulating sodium retention by the kidneys. Renin acts on its substrate angiotensinogen to yield angiotensin I, which is then converted to angiotensin II by the angiotensin-converting enzyme (ACE). Finally, angiotensin 2 promotes the release of aldosterone by the adrenal cortex, which acts on renal tubules, leading to the reabsorption of sodium and water and the excretion of potassium.
