julsineya [31]

Answer:

Explanation:

The unicellular organisms basically classified into prokaryotes and eukaryotes. In case of bacteria the nucleus was completely absent but the replication and translation process were combined together. so there is no need of complexity. The genome is under control of one replication of origin i.e. the replication of DNA and translation for proteins synthesis takes place simultaneously and again no complexity. The organism is depend on these proteins and DNA for different purposes like fission, energy production etc.

If we think about Eukaryotes there is separate boundary for DNA and protein synthesis Nucleus and rest of cytoplasm with organelles. The complexity increases because of functional variations and functions occur at different times. So the whole genome replication is not needed every time and there are separate Origin of replications for segments of DNA (genes). Along with these there are non-functional DNA segments (introns functionally they won’t give proteins). To eliminate them there is a separate process after mRNA synthesis called post transcriptional modifications. After this protein synthesis takes place at cytoplasm. There is one more check point called post translation modification where protein modification (functional diversity) allocated. To adapt the changing environment, stress, reproduce and for any functions there is a wide diversity if we compare prokaryotes and eukaryotes.

One benefit of the countercurrent flow process is
torisob [31]

Answer:

Option (a).

Explanation:

Counter current flow may be defined as the flow of water in the opposite direction with the flow of blood in the body. This countercurrent flow is generally occurs in fishes.

The one main benefit of the countercurrent flow is the absorption of maximum oxygen as the water flows inside the body. Approximately, three time more oxygen is extracted during the counter current flow. The concentration gradient is maintained up to the whole length of gills.

Thus, the correct answer is option (a).

All organisms begin life as a ____________ cell.
MrRissso [65]

Answer;

-Single

All organisms begin life as a single cell

Explanation;

-Every living organism begins life as a single cell. Unicellular organisms may stay as one cell but they grow too. Multicellular organisms add more and more cells to form more tissues and organs as they grow. Growth and development of living organisms are not the same things.

-In unicellular organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair.
