Biology
2 answers:
Aleksandr-060686 [28]3 years ago
8 0

Answer: The correct answer is -

B.The process by which new species are formed.

Speciation can be described as the process of formation of new species (that are distinct from old species) during the course of evolution of old species.

In other words, when one species gives rise to two or more different species during the course of its evolution, it is termed as speciation.

For example - 13 distinct species of Galapagos finches (bird species), which were formed from single ancestral species due to allopatric speciation (geographical isolation that occured by ocean).

Thus, option B) is the right answer.

How do archaea and bacteria differ?​
Lunna [17]

Answer:

The archaea and the bacteria both are prokaryotes. However, the genetic makeup of the archaea is more similar to the eukaryotes. Moreover, they have differences, in their metabolic pathways, genes and the enzymes possessed by them.

Explanation:

The differences between Archaea and bacteria:

1. The cell wall of the bacteria consist of peptidoglycan, while the cell wall of the archaea consist of pseudo-peptidoglycan.

2. The bacteria are capable of spore formation, which can lie dormant for long periods of time until a suitable condition is found for their growth. The archaea are not known to form such spores.

3. The genes of the archaea are more similar to the eukaryotes than the bacteria.

4. The bacteria are found everywhere where the living conditions are suitable (soil, air, living beings, non-living things). the archaea are capable of surviving in extreme conditions (hot springs, salt brine).

5. The bacteria use the process of glycolysis and follows Kreb's cycle for glucose break-down. The archaea do not undergo glycolysis or Kreb's cycle.

What phenotypes could result from the mitotic crossing over in an individual that is heterozygous for the recessive loci of sing
dlinn [17]

Answer: Hello your question has some missing data attached below is the missing data

answer : single spots for “b”, “sn”, and “y”  ( option C )

Explanation:

During the mitotic crossing over in a heterozygous individual the phenotypes that could result are single spots for “b”, “sn”, and “y” . this is because  In mitosis/mitotic crossing there is no pairing up and no swapping of chromosomal segments Hence no variations are introduced during mitosis /mitotic crossing
