Answer:
a video that shows penguin species that have different mating dances
Explanation:
The question is incomplete as it does not have the options which are:
- a video that shows a large river that has penguin populations on both sides
- a video that shows penguin species that have different mating dances
- a video that shows a penguin that is laying eggs
- a video that shows penguins in a tidal pool and an open ocean
Answer:
a video that shows penguin species that have different mating dances
<em><u>The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.</u></em>
<em><u /></em>
<em><u>The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.</u></em>
<em><u /></em>
<em><u>In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.</u></em>
<em><u /></em>
<em><u>Thus, the selected option is correct.</u></em>

Essentially 100% of the energy that fuels the earth comes from the sun. To maintain a constant global average temperature, all of the sun's radiation that enters Earth's atmosphere must eventually be sent back to space. This is achieved through Earth's energy balance.
Answer:
A
Explanation:
The DNA is made 4 nitrogenous bases. A (adenine) pairs with T (thymine) and are held by two hydrogen bonds. C (cytosine) pairs with G (guanine) and are held by three hydrogen bonds.
You might wanna remember this by the preposition 'at', which ultimately makes C and G together. Or you might wanna remember it by something like G- C<em>AT</em>.
A mechanism that is effective in maintaining a normal glomerular blood pressure only if the systemic mean arterial pressure remains between 80 and 180 mm hg is called renal autoregulation.
<h3>What is renal autoregulation?</h3>
- Autoregulation is the inner characteristic of blood vessels present in end organs, like heart, kidney, and mind, by which they dilate or constrict in response to pressure changes, thus help to keep the blood flow generally steady.
- Usually our body tries to regulate our blood pressure in range of 50 to 150 mm Hg.
- Regulation of renal blood flow and glomerular blood pressure in kidneys is called renal autoregulation.
- There are 3 mechanisms of renal blood flow namely myogenic response (MR), tubuloglomerular feedback (TGF) and third mechanism that is independent of TGF but slower than MR.

It could have the most direct effect on the amount of mitochondria in cells and also the system of the membrane.
