1 answer:
uranmaximum [27]3 years ago
7 0

Answer:

Option-D

Explanation:

Cellular respiration and photosynthesis are the two main physiological process which drives the life on Earth. Photosynthesis process leads to the synthesis of Glucose whereas Cellular respiration breakdown the Glucose molecule to form ATP molecules.

In plants, the photosynthesis process occurs in green leaves whereas cellular respiration occurs in every cell of the plant inside the mitochondria.

In the given question, the graph shows:

1. The absorption of oxygen till 6 am which is required during cellular respiration.  

2. After 6 am, the level of oxygen production becomes more than oxygen absorption till 6 pm.

3. After 6 pm, no sunlight is available therefore photosynthesis does not occur. After this, the rate of cellular respiration increases that is oxygen is taken in.

Thus, Option-D is correct.

Apply: Where in the Gizmo (and in real life) do the following energy conversions occur?
Fudgin [204]

Answer:

26. Coal is burned at a power plant

27. In dams.

28. Gas heater.

29. Nuclear power plant.

Explanation:

Coal is burned at a power plant where Chemical energy is converted into thermal and then into electrical current. In dams, water falls from higher altitude in which Gravitational potential is converted to kinetic energy by revolving of turbines which produces electrical  current. in heater, electrical energy is converted into radiant and also heat or thermal energy while the nuclear thermal energy is converted into electrical energy and this happen in the nuclear power plant.

Let’s say A plant cell, normally diploid, completely screws up mitosis during metaphase and pulls full copies of all chromosomes
andrezito [222]

Answer:

4N

Explanation:

Mitosis is the process whereby a cell duplicates or produces another identical copy of itself. The mitotic process, which occurs in four main stages produces two daughter cells that are genetically identical to the parent cell. For example, a diploid organism (2n) will produce two daughter cells with 2n from mitosis.

However, in a case whereby a plant cell (A) screws up mitosis during metaphase and pulls full copies of all chromosomes to one side. This would result in one daughter cell having 4n or tetraploid number of chromosomes. Ideally, mitosis separates the chromosomes equally into the two daughter cells to have 2n each. If one cell has all chromosomes, it means that cell will have all the 4n.

For example, in a diploid human cell with 46 chromosomes (2n). Mitosis should occur in such a way that each daughter cell will have a diploid 46 number of chromosome (2n). However, if all the chromosome ends up in one cell during mitosis, that cell will have 92chromosomes, which is 4n or tetraploidy.
