What evidence supports the theory of endosymbiosis?

Biology
1 answer:
Liono4ka [1.6K]3 years ago
5 0

The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.

Use what you know about the effect of heat on gases to explain why, the gases came out of the leaf when it was put into warm wat
lara31 [8.8K]

This happens because when leaf are submerged it is using light to continue process of photosynthesis, this process includes the release of oxygen that we see in bubble format .

<h3>Why the gases came out of the leaf when it was put into warm water?</h3>

When the leaf is put in warm water it is using light to continue the process of photosynthesis. Part of this process is to let oxygen out of the leaves. It is this oxygen that you are seeing as bubbles in the water.

<h3>Which part of the leaf the gas came from?</h3>

The only way for gases to diffuse in and out of the leaf is though small openings on the underside of the leaf, the stomata.

Please help, its for a test!

(hi, i dont know about this one personally, but i found an answer somewhere else on the internet thatll hopefully help u)

Answer: They consist of long chains of C, H, and O.

Explanation:

In terms of chemical composition, lipids differ from nucleic acids and proteins because they mostly just contain carbon, hydrogen, and oxygen (except for phospholipids which of course contain phosphorous). In addition to those elements, proteins contain nitrogen and sulfur, and nucleic acids contain nitrogen and phosphorous.

Carbohydrates share the C, H, and O composition as lipids, but they differ in structure. Lipids are generally exist as triglycerides, which consist of a triple hydroxyl alcohol (glycerol) that has bonded to three long-chain carboxylic acids (fatty acids) in a triple condensation reaction. Carbohydrates on the other hand are made of carbon ring structures that either remain alone or polymerize into long polysaccharide chains.

Which statement describes the light reaction of photosynthesis?
Hoochie [10]
It would be D. Water molecules are split apart and the byproduct of that would be the O2. As energy enters the chloroplasts, the energy excited the H2O molecules and causes them to split

What characteristics of DNA results in cell differentiation in developing embryos?
Elina [12.6K]

Hi!


The correct option is B. Which genes are active.


Embryonic differentiation is a developmental process by which embryonic cells give rise to specialized cells and a diverse range of tissue structures. All of this unique cells essentially rise from a type of cells that are known as pluripotent cells.

But how do these pluripotent embryonic stem cells know which cells to differentiate into? This is where genes come into play. The cell has an inherent signalling ability that determines which gene is to be active and expressed. These specifically activated genes then translate into proteins for which it is specific, giving each cell, tissue and organ its particular identity.


Hope this helps!
