The correct answer is: A. hydrolysis of ATP to ADP

This step occurs in the light-dependent phase of photosynthesis.

Calvin cycle is the second phase of photosynthesis also called light-independent reactions (no light required for this step). This process occurs in in the stroma (the inner space of chloroplasts) and during it three-carbon sugars are produced from CO2. Calvin cycle can be divided into three steps:

1. Carbon fixation where CO2 from the air is “apsorbed” by plants and combined with a five-carbon acceptor molecule, ribulose-1,5-bisphosphate (RuBP). Formed molecule with 6 C atoms is then split into two 3-phosphoglyceric acid (3-PGA) molecules by the enzyme rubisco.

2. Reduction refers to conversion of 3-PGA to glyceraldehyde-3-phosphate (G3P), sugar that can be used in further steps of photosynthesis. NADP+ is reduced to NADPH.

3. Regeneration refers to recycle of some G3P in order to regenerate the RuBP acceptor for the carbon fixation.

Constant speed would have a straight and diagonal line either facing upwards or downwards in the graph. This is because speed is displacement divided by time, which becomes the slope of the graph.

Answer:

As comic is not available, lets try to understand genetic drift generally.

Explanation:

Genetic drift can be described as the changes in the allele frequency or changes in the genotype variations of a population due to certain reasons such as death etc. In genetic drift, a particular genotype of a species starts to decrease, while the other genotype might start to increase. For example, imagine there are 6 colours of rabbits to be seen in a population. An event such as a diseases takes over which results in death of most of the rabbits. Only a few rabbits are left having brown and grey colour. Hence, the genetic drift changes from 6 to only 2.

This would cause the overpopulation in the grassland preserve. There would be too many antelopes and zebras that they would have to compete for survival. The food resources would run out for both species and cause a competition among every animal.

The cell in the diagram is a plant cell because it has chloroplasts and a cell wall.

There are two types of cells animal cells, which are the ones that humans and animals have, and plant cells, which are the ones that plants and trees have. They share some organelles, but they also have some that are specific to each type.

The plant cell parts in the picture are:

  • Rough Endoplasmic Reticulum: it is where the ribosomes are. The synthesis of proteins happens there.
  • Chloroplast: it is an organelle-specific of plant cells. They are in charge of photosynthesis.
  • Cell wall: it is only present in plant cells. It surrounds the membrane.
  • Mitochondria: It is the place that generates the energy that the cell needs.
  • Vacuole: they are bigger in cell plants than in animal plants. It has many functions, but one is to store water.
  • Membrane: it draws the limits of the cell.
  • Golgi Apparatus: it is the place where proteins go to be distributed.
  • Nucleus: it contains DNA, and it has a membrane around it.
  • The nucleolus: is the larger part of the nucleus. It is in contact with the endoplasmic reticulum.

To sum up, the plant cell has a bigger vacuole than the animal cell; it also has chloroplasts and a cell wall, which are not present in the animal cell.
