Answer:

These organelles are contractile vacuoles

Explanation:

Contractile vacuoles are intercellular pumps that are slowly filled with fresh water and eventually expel their contents outside the cell. Freshwater protists maintain the hydric equilibrium by contractile vacuoles that pump out the water of the cell and thus prevent the cell swelling induced by osmotic stress.

As cytokinins are primarily produced in roots, what route would they travel to influence lateral shoot formation in a recently t

Bond [772]

The answer is symplastic transport. Transport of phytohormones such as cytokinins occurs through cytoplasm from cell to cell through plasmodesmata. Cytokinins travel up the xylem and promote lateral growth. Gaseous molecules, such as ethylene, emitted and received by plants must pass the apoplast.

Which of Darwin's postulates are vital in order for evolution to take place?

andriy [413]

Answer:

Charles Robert Darwin was a British naturalist and biologist known for his theory of evolution and his understanding of the process of natural selection

Explanation:

2. Some of these variations are passed on to offspring;

As the genetic changes may occur due to mutations in the genes.
As these changes do not occur in days or months but they occur after hundred and thousands of years.
The off springs are distinct from their ancestors. This results in the formation of new species. Gradual modification of the existing species leading to the formation of new species is known as speciation.

4.Individuals vary in their ability to survive and reproduce;

Those with the most favorable adaptations are more likely to survive and reproduce.
Individual variation (usually through mutation) may introduce traits or abilities that enable that individual to survive in order to reproduce. Usually these are tiny incremental changes that accumulate over centuries or millennia.

Note: However there are certain drawbacks of Darwinism even such as it failed to explain the basis of variation and the mode of transmission of characters.
