Which of the following plant adaptations aids grassland plants to recover from fires?

Heavy rains and mudslides cause a river to change course, isolating two groups of lizards from one another. If they remain isola

Stells [14]

If they remain isolated for a long period of time, the two groups will probably diverge genetically, and may result in speciation.

Genetic divergence is the process whereby two groups of the same ancestral species acquire autonomous genetic changes through time, usually after the groups have been separated reproductively for some period of time.

Speciation is an evolutionary process whereby populations develop to become different species.

Which of the following statement(s) is/are TRUE about Red Blood Cells (RBCs)? a) A normal RBC has a nucleus RBCs' production is

olga_2 [115]

Answer:

RBCs' production is controlled by erythropoietin.

Mature RBCs are released into the bloodstream after approximately seven days RBCs are produced in the bone marrow

Explanation:

The hormone erythropoietin is produced and released in the bloodstream by peritubular interstitial cells of kidneys. The function of erythropoietin is to increase the number of the precursors of red blood cells and thereby to stimulate the production of red blood cells in the bone marrow. When the oxygen supply to body cells is reduced, the hormone erythropoietin stimulates the development of proerythroblasts into reticulocytes and thereby increases the RBC production.

RBCs are produced by the process of erythropoiesis and take about seven days to become mature and to be released in circulation to serve the function of oxygen delivery. The maturation of RBCs also includes the loss of most of the organelles such as the nucleus and mitochondria to accommodate hemoglobin protein. The life span of circulating RBCs is about 100-120 days.

The tiles below depict translation events during roughly two cycles of elongation. each cycle adds a leucine (leu) amino acid to

sergij07 [2.7K]

I found the attached image on the internet and I believe it has the tiles referred to on the question.
As we can see on the image, the A-site, P-site, and E-site are represented. The A-site is occupied by the tRNA linked to the growing peptide chain. The P-site is the one occupied by the tRNA that works accepting the growing protein for peptide bond formation.
Firstly, the protein is formed, it is the first tile from the left.
Then, the first tile from the right is where the Leu is formed.
On the second tile from the right the Leu is then added to the protein.
The process is then repeated again as there are two cycles of elongation adding a Leu in each of them: third tile from the right, third tile from the left, second tile from the left.
