experimental evidence shows that the process of glycolysis is present and virtually identical in organisms from all three domain
puteri [66]

The question is incomplete as it lacks the multiple options. The multiple options are as follows:

a. Across the three domains, all organisms depend solely on the process of anaerobic respiration for ATP production .

b. Glycolysis is a universal energy-releasing process and therefore suggests a common ancestor for all forms of life .

c. The existence of glycolysis as an energy-releasing process in all organisms suggests that convergent evolution occurred .

d. All organisms carry out glycolysis in mitochondria.

Answer:

Option (b).

Explanation:

The three main domains of life are prokarya, eukarya and archaea. The archaea and eukarya are more closely related with each other than the prokarya.

The glycolysis is the process of breakdown of glucose molecule to generate ATP. The glycolysis is the most common process of the generation of the ATP are present in almost all the organisms whether the organisms is ancestral or modern.  

Thus, the correct answer is option (b).

Fully explain in your own words your thoughts on the following questions: Are mutations good or bad for a population?, IN YOUR O
marysya [2.9K]

Answer:

mutations can be either beneficial or harmful depending on the environment

Explanation:

Mutations can be defined as genetic changes in the nucleotide sequence of the genome of one organism. Mutations are usually neutral, but they can also be deleterious and/or beneficial depending on the environment. For example, recessive mutations that cause sickle-cell anemia, which is a recessive genetic disease that affects homo-zygous individuals, have shown to be advantageous for heterozygous individuals living in regions where malaria is endemic. Beneficial mutations can be selected by natural selection, thereby increasing their frequency in the population.

Select the statements that accurately describe endocytosis. The cell membrane pinches off to form an extracellular vesicle joine
noname [10]

Answer: The cell membrane invaginates and pinches off, creating a vesicle within the cell.

Explanation:

Endocytosis is an active transport mechanism, for particules to be transported, the plasma membrane of the cell invaginates, forming a pocket around the target particle. The pocket then pinches off, resulting in the particle being contained in a newly created intracellular vesicle formed from the plasma membrane.
