Some Eukaryotic cells have internal structures that are able to use photosynthesis to convert light energy into chemical energy

(as bonds in sugars). Why is this capability not found in all Eukaryotes?

Answer:

The endosymbiotic event that brought chloroplast in eukaryotic cells happened after the lineage delivered.

Explanation:

The endosymbiotic theory says that the ancestral cell gains the ability of photosynthesis when it engulfed a photosynthetic bacteria and this bacteria remained in a symbiotic relationship with the ancestral cell and evolved as chloroplast in plants that can perform photosynthesis.

All the eukaryotes do not have this internal structure like chloroplast because this endosymbiotic event must be happened after the divergence of the lineage into different groups. Therefore plant cells have chloroplast and animals cell do not have.

The question is incomplete as it does not have the options which are provided in the attached picture.

Answer:

Option-B

Explanation:

The theory of the endosymbiotic origin of eukaryotes proposed that the organelles like the chloroplast and mitochondria are originated when the proto-eukaryotes engulfed the prokaryotic cells.

The chloroplast was formed in some eukaryotes instead of others as the proto eukaryotes diverged into many lineages before the origin of the chloroplast in them. One of the lineages engulfed the chloroplast and become photosynthetic organism but rest of the proto eukaryotic lineage did no engulfed the bacteria and did not possess the chloroplast.

Thus, Option-B is the correct answer.

What should the student say to the astronaut to explain the shape of the planets' orbits around the Sun? In your answer, discuss
Rudik [331]

The shape of the planets' orbits around the Sun in this scenario can be referred to as an elliptical shape.

<h3>What is an Elliptical shape?</h3>

This is similar to the shape of an ellipse in which the elongated circle stretches into an oval.

The shape of the orbits of the planets are all nearly circular as a result of the distance of the planets from the sun being millions of miles apart.

Explain why a red object appears red to the human eye. (1 point)
REY [17]

Given what we know, we can confirm that sunlight is white light, when it shines on a red object the red wavelength is reflected. The other colors are absorbed, so the only thing you see is the red light reflected back.

<h3>What is white light?</h3>

We use "white light" as a term to describe the combination of all colors of light in the spectrum. The sun emits all colors of light, when this light hits an object, most of the colors are absorbed. The color that does not get absorbed is reflected back and causes us to perceive the object in that color.

Therefore, we can confirm that sunlight is white light, when it shines on a red object the red wavelength is reflected. The other colors are absorbed, so the only thing you see is the red light reflected back.
