HEY DEAR..
1》 All stars die, and eventually — in about 5 billion years — our sun will, too. Once its supply of hydrogen is exhausted, the final, dramatic stages of its life will unfold, as our host star expands to become a red giant and then tears its body to pieces to condense into a white dwarf.
so options B is the correct answer.
2》protostar is the answer...
hope its helpfull
The answer is <span>A. Decrease in genetic variation
</span><span>
A founder effect is a result of a geographical separation of a few individuals from the original population. Those few founding individuals will form a new population so they are founders. In this new population, there will be present alleles of the few founding individuals. However, those few founding individuals do not represent a whole genetic variation of the old population, but only some part of it.
Imagine a population of fish in which there are yellow, green, blue, and red colored fish. In the population, there is a genetic variation. But, if a few green-colored and red-colored fish geographically separate from the population and form a new population, in the new population there will be decreased genetic variation (because there are only green and red fish compared to the old population where are fish in 4 different colors).</span>

Photosynthesis is done only by plants by using sunlight water and CO2
All living organisms can do cellular repirations
She is wrong because she said plants only do photosynthesis but that's not true because trees do cellular repiration too because when there is no sunlight they need energy. So what they do is they break down the sugar doing glycolysis by using mitochondria. Sidenote:Both plants and animals have mitochondria in their cells.They need energy right when there is no sun.So they use glycolysis.Glyco means sugar and lysis means break down.Then there come 2 steps.
Aerobic Respiration
Anaerobic Repiration
If the sugar that we just break down contains oxygen the that sugar falls to the aerobic respiration
If it does not contain sugar it goes to Anaerobic Respiration
Aerobic Respiration : It would use Kreb Cycle to Make 2 ATP.ATP is for Adension Tri Phosphate. Which is basically enregy.Then there comes Electron Transport Chain.Where they use protons to gain 32 ATP.Overall
2 ATp from glycolysis 2 from Kreb Cycle and 36 from ETC so 36
Anerobic: They fall part to 2 major respirations of this section which are
1. Alcoholic Repiration - It contains no oxygen, gain 2 atp and used to make breads and alcohol
2.Lactic Acid - gain 2 ATp and no oxygen and used in yogurt you eat and it creates sore in your muscles
She is wrong because that is completely wrong statement that trees only do photosynthesis but no they use cellular Respiration to gain energy from ATP when there is no sun available to them
Hope that answers the question
