Answer:
C
Explanation:
An RRYy parent can form four different gametes: RY, Ry, rY, and ry.
Gametes are reproductive cells that are responsible for the genetic makeup of offspring. In animals, these cells are known as sperm and eggs, and in plants, they are known as pollen and ovules.
Gametes contain half the number of chromosomes as the parent cell, allowing for genetic recombination and diversity in offspring during sexual reproduction.

A. This is an example of a block design.
B. This is an example of a completely randomized experiment
C. This is an example of a matched pairs experiment.
D. The treatments are diets A and B.
E. The treatment is how much weight a rabbit loses.
F. The experimental units are the 20 rabbits.
G. The experimental units are diets A and B
Answer:
A. This is an example of a block design.
D. The treatments are diets A and B.
F. The experimental units are the 20 rabbits.
Explanation:
The randomized block designs are used in experiment when there is only one variable of prime importance but along with it there are several nuisance factors. As in this case, the prime variable is the impact on weight of rabbits when they consume one the given diets. However, several nuisance factors are unequal weights of the rabbit, different class of rabbits, eating habits of rabbit, time of feeding etc.
Treatment in an experiment is the independent variable that is varied to measure its impact on the subjects of the experiment.
Here these independent variables are diet type A and B and the subject is the group of 20 rabbits. Subjects are also referred as experimental unit i.e on which the experiment is being conducted
Hence, option A, D and F are correct

The primary consumer in the food web is the zooplankton.
In the given food web, the primary consumer is the zooplankton. The primary consumers are organisms that consume producers, which in this case are the phytoplankton. Zooplankton are small organisms that eat the phytoplankton, making them the first level of the food chain.

Answer: Move substances
Explanation:
The process of diffusion and active transport are some of the process inside the body which helps in transportation of the materials from one place to another.
The substances move a region of higher concentration to lower concentration in case of diffusion and with the help of energy the molecules moves from lower concentration to higher concentration.
The correct answer is option D.
