Answer:

Option (B)

Explanation:

Photosynthesis is an important process that plants carry out, in which the plants absorb the energy provided by the sun, in the presence of CO₂, water and in return, liberates food, oxygen, and some water. This is how the green plants prepare their own food and the consumers are directly dependent on them.

This process helps in converting light energy into chemical energy.

Thus, the correct answer is option (B).

Due to inability to survive in aerobic condition.

The strain dies when exposed to a normal laboratory atmosphere instead of nitrogen gas atmosphere because the mutation causes change in the capability of the strain to survive in the aerobic conditions. This mutation inactivate several enzymes which is also responsible for their capabilities of surviving under both anaerobic and aerobic environment so that's why the strain dies when exposed to normal atmosphere..

If a true-breeding blue-flowered plant was crossed with a true-breeding white-flowered plant, what phenotypic ratio would we obs
Westkost [7]

Answer:

B. 100 percent white

Explanation:

According to Mendel's law of dominance, the dominant allele of a gene masks the expression of the recessive allele in a heterozygous state. Therefore, when two pure breeding plants that differ with respect to one genetic trait are crossed, the progeny expresses only the dominant phenotype. Here, one allele should be completely dominant over the other. The allele for the white flowers is completely dominant over the allele for the blue flowers.

Let' assume that the allele "W" imparts white color to the flowers while the allele "w" gives blue color. When a true-breeding blue-flowered plant (ww) is crossed with a true-breeding white-flowered plant (WW), the progeny would be heterozygous for the dominant allele "W" and would exhibit "white color of flowers" (the dominant trait).

WW (white-flowered plant) x ww (blue-flowered plant) = Ww (white-flowered plant)

PRE-LAB QUESTIONS 1. What is the difference between chemically defined and chemically complex media? Give either a clinical or e
larisa86 [58]

Answer:

Explanation a chemical define media is a media that do not contain any animal derived source as a component. It is a media whose chemical component are known. It is said to be the purest form of media for culture.

Complex Chemical media is a media whose component are not known. It includes both animals,yeast, plant source whose component are not known this Mixture makes it complex.

Example of complex media is Human Endothelial-SFM (Life Technologies), Endothelial Basal Media, EndoGRO-LS Complete

Example of chemically defined media enhancing or inhibitory effects of GSLs and sphingolipids on tyrosine kinases associated with growth factor receptors.
