When small stars die, light elements are released. Explain why.

Biology
1 answer:
Zina [86]3 years ago
3 0

Answer:

Only the bigger stars can produce heavier elements. This is because these stars can pull up their temperatures higher than the smaller stars like our Sun can. After hydrogen is used up in these stars, they go through a series of nuclear burning depending on the types of elements produced, for example, neon burning, carbon burning, oxygen burning or silicon burning. In carbon burning, the element goes through nuclear fusion to yield neon, sodium, oxygen and magnesium.

Why does the pilobolus use such an explosive method to disperse its spores??
Alex_Xolod [135]

So it does not land in the zone of repugnance, a zone which prevents the spores from being consumed by the cow. (zone of repugnance is a zone of which a cow will not eat grass, this explosive dispersal of spores will allow the spores to be eaten by a cow and later pooped out to grow into a beautiful fungus)

Researchers have found that mitochondria and chloroplasts in eukaryotic cells have their own DNA. This DNA is different from the
ikadub [295]

Answer:

B. Early Eukaryotic cells engulfed mitochondria and chloroplasts

Explanation:

Mitochondria and Chloroplast are organelle that are found in cells of higher animals. Chloroplast are found almost exclusively in plants and mitochondria is found in animal cells. The function of these organelles are to produce energy to the cells, and by extension, the organism that they live in.  

Unique features of these organelles show that they have their own DNA and divide and multiply on their own. This strongly suggest that they were once free living prokaryotes and were engulfed by larger cells and a symbiotic relationship began.

As time progressed, these prokaryotes did not require all of their genetic information and this was removed from their system. They kept essential genes and regulatory bodies separate that they needed for their maintenance and function that they provide.

How does polygenic inheritance differ from mendelian inheritance
Luba_88 [7]

Answer:

Mainly, the number of genes that control traits.

Explanation:

Polygenic inheritance does not follow Mendel's law of dominance. According to Mendel the dominant trait will mask the recessive trait however, this is not always the case. Polygenic inheritance states that traits are controlled by two or more genes and is also dependent on the environment.

Let's take skin color for example. A fair-skinned person will have a child with a dark-skinned person.

Mendelian inheritance would assume that the offspring would either be fair or dark only.

Polygenic inheritance would assume that the offspring would be either fair, dark, or a tone in between, depending on the environment they are in as well.

Hope you understood it.
