Answer:

Budding cells formed by the Saccharomyces are through "Cytokinensis"

Explanation:

Cytokinensis helps the budding cells of the Saccharomyces to get splitted over two new cells. These buds raise, throughout its cell cycle and afterwards leaves its mother cell while mitosis been completed. Budding of the yeast makes up an perfect model for the creature to study the meiosis. Diploid yeast can be prepared by making it undergo through meiosis in absence of nitrogen which will lead to the generation of an ascus along with 4 haploid cells. Due to this the property of the meiotic products can also be studied.

Answer:

a. 0.7

b. 0.3

c. Yes

d. 90

Explanation:

As the random mating population was escaped from external evolutionary forces such as mutation, natural selection, and migration, the gene frequency will not change over time. The population will be at Hardy-Weinberg equilibrium throughout the time.

As the number of sleepyheads (recessive trait) was 90 out of class of 1000 students at the start of course.

q²=0.09 ∵ fraction of sleepyheads = 90/1000 = 0.09 denoted by q²

q that is the recessive gene frequency will be equal to 0.3 (by taking square root of P²

Hence, allele frequency of a allele is 0.3

As, frequency of dominant allele A is denoted by letter p and p+q=1

∴ p=0.7 As p=1-0.3

Hence, allele frequency of A allele is 0.7

Counting the probability of aa alleles (sleepyheads);

As a= 0.3

∴ aa= 0.3×0.3 = 0.09 (In terms of percentage, it is 9%)

To 0.09×1000= 90 or 9% of 1000 = 90

Hence, 90 students should be sleepyheads.

Volgvan

Answer:

Only one of the three statement is true; and that is,

(ii.) Different metabolic end products result from the two types of fermentation

Explanation:

Fermentation is the process by which organic molecules such as glucose are broken down into smaller molecules to extract energy as ATP in the absence of oxygen.

Fermentation is carried out by many organisms including man.

In man, fermentation occurs in very active skeletal muscles such as in an athlete running. It involves the reduction of pyruvate produced from the glycolytic pathway to lactate in the muscles. The net yield of ATP from glucose breakdown to produce lactate is 2 ATP molecules.

In microorganisms such as yeast, the fermentation product of py ruvate derived from glycolysis is ethanol and carbon dioxide, CO₂. The net ATP yield in fermentation of glucose in yeast cells is also 2 ATP molecules.

From the options provided in the questions, the correct option is:

Only one of the three statement is true and that is that, ii. Different metabolic end products result from the two types of fermentation.

Histamines are released when mast cells are exposed to _____, which are fragments of complement proteins.

IrinaVladis [17]

The answer that best fits the blank provided above is C3a and C5a. Mast cells release this so called histamines once they are exposed to C3a and C5a which are fragments of complement proteins. These are also called as Anaphylatoxins along with C4a. Hope this helps.
