The endosymbiotic theory stated that the mitochondria of eukaryotic cells are actually prokaryotic bacteria which were once engulfed by prehistoric eukaryotic cells as a result of evolution.

 

Therefore to answer this question, here are some characteristics: 
1 Both mitochondria and prokaryotic cells contain their own DNA.

2 Neither of the two have true nuclei, but they do have a space in which their DNA is enclosed. 
3 Mitochondria and prokaryotic cells have similar transcriptional machinery, which means that they have the same process of making RNA from DNA.

<span>4 Mitochondria contain their own genome, and the formation of their genome in most organisms is circular similar to prokaryotes.</span>

Why might (mostly) boneless creatures, like jellyfish, sea slugs, squid, and octopuses, fare especially well underwater? What is
vagabundo [1.1K]

Answer:

The species that develop in aquatic environments, need to be able to have an adequate locomotion and according to the hydrostatic pressure in the water, which this pressure has the opposite direction to gravity in terrestrial life.

Explanation:

Vertebrates that have a skeleton are accustomed to gravitational forces, and this bone structure is what allows adequate locomotion to perform movements as a function of the force of earth's gravity, in water the force of gravity has no effect, since that the hydrostatic force predominates, which the direction is opposite to the gravitational forces.

Amorphous bodies, with few solid structures, not bony, make them better adapt to movements in water masses that are promoted by hydrostatic forces.

Neurospora crassa was one of the first eukaryotic microbes to be adopted by geneticists as a model organism. It is a haploid fun
Anna007 [38]

Answer:

A) They have low-maintenance and are easy to keep track of for mutations.

B) The deduction can be "Single Gene Mutation"

Explanation:

After examining the example given in the question on Neurospora crassa and the details about how they reproduce, the following points can be made regarding the questions;

A) It is stated that they form a colony in time and that they are asexual spores and the first reason to choose them would be because they contain somatic cells (which refer to the cells other than reproductive cells) and non-motile gonidia which can multiply by dividing themselves and these properties make the colony's maintenance easy. And since they multiply by division, it is easier to keep track of the occuring mutations.

B) Given the information in the question that the mating is between an albino strain and a wild type, and then between two albino strains which have the same genotype. The results indicate that the strains have gone through single gene mutation during the process.

I hope this answer helps.

What is plant blindness?
Komok [63]

Answer:

The answer is A.

Explanation:

Plant blindness refers to "the inability to see or notice the plants in one's own environment." The term plant blindness was coined twenty years ago by Elizabeth Schussler and James Wandersee who are botanists. Plant blindness results in "the inability to recognize the importance of plants in the biosphere and in human affairs." It is also the reason why people have a tendency of ranking “plants as inferior to animals”. Therefore, plants tend to receive limited care and upkeep. It is important to recognize plant blindness so that more intentional care can be given to preserving our plant species and ensure their survival and ability to thrive.
