The theory of endosymbiosis is supported by all but which of these observations?

Answers

Answer 1

The exterior arrangement similar to bacterial cell walls is not an evidence in favors of the endosymbiotic theory. Endosymbiotic theory States that organelles such as chloroplasts and mitochondria were once free-living prokaryotes which eventually lived symbiotically within larger cells, forming modern day eukaryotes.

In addition to the lack of histones, mitochondria and chloroplasts have circular, single stranded DNA. Single stranded, circular DNA is found exclusively in prokaryotes. This evidence supports the endosymbiosis theory because these characteristics would allow the mitochondria and chloroplasts to survive on their own. Evidences that support endosymbiotic theory are presence of DNA, size of ribosomes, Inhibition by antibiotics, evolutionary relationship.

please answer please, If we have a male hemophiliac (such as Leopold) marry a normal female, is there any way to have sons who have hemophilia? Provide a justification for your response.

Answers

Yes, hemophilia is a genetic condition, which means it can be genetically passed down to a male child, even if only one parent is a hemophiliac. The condition is also more common in male children, and is a sex-linked recessive disorder, and is carried on the X chromosome. The mother could also have the gene without actually having the disorder, so she could possibly be a carrier without knowing it, so it is possible for their son to have hemophilia, even if the dad is the only one with the gene.

The appendix, an extension of the large intestine appears, although this is debated, to have little
function in humans. What is the appendix an example of in terms of evidence for evolution?​

Answers

Answer: Vestigial organ

Explanation:

Vestigial organs are those organs which were functional in ancestral organisms belonging to the same species but due to the course of evolution of body forms they become non-functional. They can be found in the body either in the same form as used to appear in the ancestors or in rudimentary or degenerated forms.

The human appendix is one of the examples of vestigial organs. It looks like a narrow tube which forms a link with a colon of the large intestine. It was functional in human herbivorous ancestors as it used to help in digestion of variety of vegetables and other plant products. The change of diet along with due course of evolution caused the appendix to become useless. But the appendix physical form remained the same in humans.

Prokaryotic cells generally have a higher surface area to volume ratio than eukaryotic cells.

Answers

Answer:

true I think I just guessed

TRUE : Prokaryotic cells  generally have a higher surface area to volume ratio than eukaryotic cells

Eukaryotic cells are larger and complex when compared to prokaryotic cells which makes its surface area to volume ratio to be smaller than that of prokaryotic cells. cells are classified based on the arrangement  of their cell structures.

Prokaryotic cells are found in smaller organisms like Bacteria while Eukaryotic cells are found in larger organisms like Humans and Plants.

Hence we can conclude that based on the complexity and size of the Eukaryotic cell, the prokaryotic cells generally have a higher surface area to volume ratio.

Answers

Answer:

D

Explanation:

The correct answer would be that the origin of all cells can be traced to previous or pre-existing cells.

According to the cell theory which is made up of three parts;

The cell represents the basic unit of all life.All living organisms are made up of cells.Cells do not arise spontaneously, but only from pre-existing cells.

Hence, the discovery that the origin of all cells is traceable to previously existing cells supports the latter part of the cell theory.

The correct option is, therefore, D.

If a chromosome comes apart because it is not well attached at the center, The most problem is likely with chromatin.

What is chromosome ?

A chromosome is  a thread-like structure present in the nucleus of cells such as both prokaryotic and eukaryotic cell and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.

It is composed of three components, DNA, proteins and RNA,  amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.

Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).

The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome  is present in two forms such as Euchromatin and Heterochromatin.

Describe how you will estimate the rate of photosynthesis.

Answers

Explanation:

there are various methods to measure photosynthesis: Uptake of CO2 by plants: Since CO2 is needed for photosynthesis, measuring how much of it is taken up by the plants gives us information on how much of photosynthesis is happening. Release of O2: The amount of O2 produced during photosynthesis can be measured.

Estimation or measuring the rate of photosynthesis can be done by:

by the production of oxygenthe uptake of carbon dioxideIndirectly by an increase in biomass.

The rate of photosynthesis is a gross measure of the rate at which a plant captures radiant energy and fixes it in organic carbon compounds. It can be estimated by:

Depletion of the substrate that is carbon dioxide, has been used or how much water is used.the accumulation of oxygen is a measure of the rate of reaction.measure the rate of photosynthesis in leaves by observing the release of oxygen
