Answers
The dominant traits are those that are expressed phenotypically, whereas recessive traits are masked by the dominant traits.
- The percent of offspring having dimples are 50 percent.
- The percent of offspring will be roan and expressing both the colors will be 100%.
The dimples are the traits, which are expressed phenotypically.
Let the alleles for the heterozygous parent with dimples be Dd. The other parent not having dimples will have the genotype dd.
The combination between the Dd and dd will result in:
Dd, Dd - heterozygous combination of alleles
dd, dd - purebred for the alleles
Similarly, the genotype of the hair color of the horse is white and black .
The cross between the parental genotype will result in 100% heterozygous offspring with genotype
The result will be due to codominance, in which both the characters of the parent will be expressed in the offspring such that the horse will have black and white colors.
Therefore, the answers will be 50% and 100%.

Answer:
Receiving the same amount of light intensity and water. Being grown in the same type of soil ensures that the above listed constant variable is maintained to ensure that any changes to rate of plant growth is solely due to changes in pH level.
Explanation:
The variable that u are testing Is change in pH level. Hence, to ensure results are reliable, u need to hold the other variables constant.
Final answer:
To increase the validity of this experiment, the researchers should replicate the experiment under different conditions or with a larger sample size. Further, running additional experiments with watering solutions having different pH levels could help in understanding the optimal pH for radish growth.
Explanation:
The activity that might aid in increasing the validity of this experiment on whether the pH of water affects the growth of radish plants is the replication of the experiment, preferably under different conditions or with a greater sample size. More experimental groups with varying pH levels may also make the results more valid and reliable. This means, instead of just having a group with a pH of 3.0 and another with a pH of 7.0, the researchers could consider using watering solutions with a pH of 4.0, 5.0, 6.0, and so on. This would help in pinpointing an optimal pH for the growth of radish plants and make the results of the study stronger.

Endocytosis is a process that moves materials into a cell via vesicles. The cell's membrane folds inward to form a vesicle which then moves into the cell with the material. It is a way for cells to engulf materials in their environment.
Explanation:
Endocytosis is a process that moves materials into a cell via vesicles.
Specifically, during endocytosis, the cell's membrane folds inward to form a vesicle that contains the material to be brought inside the cell. This vesicle then separates from the cell membrane and moves into the cell, carrying its contents with it.
This is a way for cells to engulf and 'eat' materials in their environment, which can include things like nutrients or other smaller cells.

In hens, the fertilisation of it's egg occurs inside the body where as in frogs, the fertilisation of eggs happen on the water that is, it is external. Again a hen's egg has a hard shell whereas the egg of a frog does not have a hard calcareous shell ,instead it is protected by a soft jelly like substance.this shows the different types of fertilization.
