Gregor Johann Mendel made significant effect on the aspect of genetics and heredity in Biology and science generally.

If you look at the world today, you are going to see beautiful and improves varieties of plants and animals which are known as hybrids.

For his research on inheritance, he cross pollinated parents with different traits to produce offsprings.

During the cell cycle, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell
Yuliya22 [10]

Uncontrolled production of cyclins will most likely result in uncontrolled division of the cell.

CELL DIVISION:

  • Cell division is a biological process that every cell undergoes to replicate themselves. It is the process by which cells are multiplied in living organisms.

  • According to this question, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. However, at the end of the cycle, the cyclins are degraded to prevent further signaling for the cell to divide.

  • In a case whereby there is an uncontrolled production of cyclins, this will most likely result in uncontrolled division of the cell because cyclins stimulate cellular division.

Which of the following statements about extinction is true? Choose one: A. Recent species are disappearing so slowly that resear
JulsSmile [24]

Answer:

C. At least five mass-extinction events have occurred during the last 500 million years.

Explanation:

  • The history of mass extinct is related to the five mass extinctions that are caused over by the 350 million years n which many species have disappeared in there short geologic time.
  • A massive extinction is caused in the Permian Triassic extinction event i.e about 250 mn years ago which on an estimate has killed 90% of the species.
  • The Cretaceous–Paleogene extinction event that occurred over 66 million years ago is known to have wiped out the dinosaurs and many other species.

Answer:

Net photosynthesis- 3mm/20min- 1.5mm/10min

Cellular respiration- 1mm/15min- 0.66mm/10min

Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)

Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr

As we are measuring rate of photosynthesis in hr ,we should multiply gross photosynthesis with 6 (as we measured gross photosynthesis for 10 min).

A cytoskeleton is:_______.
Softa [21]

Answer: e

Explanation: Cytoskeleton is a microfilaments, intermediate filaments, and microtubules that provide support and movement for eukaryotic cytoplasm.

1. Prokaryotic cytoplasm lacks certain features of eukaryotic cytoplasm, such as cytoskeleton and cytoplasmic streaming.

2. The cytoskeleton provides support and shape to cell.

3. It help in transporting substances through cell.

4. It help in phagocytosis.

5. It help in cytoplasmic streaming that is movement of eukaryotic cytoplasm from one part of cell to another which help distribute nutrients and move the cell over the surface.

6. The study of the numerous interaction between microbes and host cell cytoskeleton is a very intense area of investigation on virulence mechanism.
