The control group is the main one because it acts as a benchmark to balance the results of the experiment.
What is control group in the experiment?Control groups are a principal aspect of true experimental designs. The presence of control groups authorizes researchers to confirm that study results are due to the drafts of independent variables rather than irrelevant variables. The control group of an experiment is a group that is not revealed to the independent variable and thus serves as a benchmark to which to compare the outcome of the experimental group. An experimental group, also known as a use of group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be similar in all other ways.
So we can conclude that an example of a control group is a group of individuals in a detached trial that receive placebo pills instead of medication.

Please write about Gregor Mendel and his research with pea plants and early genetics. In your writing you will need to correctly use the following words so that their meaning is understood. Some pictures are presented if you want to use them.
●Sexual Reproduction ●Hereditary ●Traits ●Purebred ●Phenotype
● Genotype ●Dominant allele ●Recessive allele • genes • Probability
Answer:
Answer: Gregor Mendel is an Austrian monk that studied genetics and heredity. Mendel wanted to determine how traits were inherited by offspring. many believed that heredity blended together in offspring. He used pea plants for his experiment because they reproduce sexually. He used cross-pollination in order to fertilize one pea plant by using the pollen of another. For each trait he studied, all hybrid offspring had only one character from each parent. The allele that appeared in the phenotype appeared to be dominant, and the allele that only showed up in the genotype and not the phenotype. In his expiriement he concluded that different forms of a gene account for the variations in the inherited traits. An organism inherits two genes, one from each parent, the probabilty of inheriting this trait depended on if it was dominant or recesive. Some alleles dominate others for a given trait (dominant and recesive.) And Finally the genes of a given gene segregate during gamete production.

what change in a population would you expect to see if a selection pressure was against the traits of the dominant allele?
The change in population in the given condition would be an increase of true recessive traits in the population and there would be only a few individuals with dominant traits.
In case of selection pressure was against the dominant trait, then individuals of the population who have true recessive alleles would have an advantage over the heterozygous and dominant individuals of the population.
There would be very few individuals carrying its dominant genotype and it may eventually be extinct, however, it would be still dominant. The recessive trait would just become more prominent rather than becoming dominant.
Thus, the number of recessive traits would increase in population, and the number of dominant decrease to numbers.

Decrease occur in the population of dominant allele occurs.
Change in a population of dominant allele occurs if a selection pressure was against the traits of the dominant allele because the selection pressure is against the dominant allele that leads to appearance of recessive allele and disappearance of dominant allele. The selection pressure is responsible for the appearance of allele in the offspring so we can conclude that dominant allele is decreases in the population of the future generation.

The athlete's result will be
higher than
the normal healthy
body's result.
Why?
Answer:
Explanation:Oxygen molecules absorbed by cells: The athlete's result will be
the normal healthy body's result.
Athlete inhale high amount of energy s compared to normal healthy person.
The athlete's result will be higher than the normal healthy body's result for oxygen because athlete do hard activities which needs high amount of oxygen in order to release high amount of energy in the form of ATP. This energy is used by the body of athlete in their hard activities.
While on the other hand, the normal healthy person inhale less oxygen because he do normal activities and does not need high amount of energy for that activities so we can conclude that athlete inhale high amount of energy s compared to normal healthy person.

Conduct online research to learn more about competition between two species not mentioned in this lesson. Make sure to include information about their niches, common resources, and other competitors.
Answer:
In many forest ecosystems, squirrels and chipmunks compete for acorns and some other resources. However, they don’t have the exact same niches. Squirrels nest in trees, while chipmunks live underground. These species don’t compete with each other for mates either. Thus, squirrels are in interspecific competition with chipmunks.
All squirrels in a particular ecosystem share the same niche. The same is true of all chipmunks. So, both of these species are in intraspecific competition. Competing with an individual from the same species is harder than competing with members of other species. For example, squirrels compete with other squirrels for not only food (acorns), but also shelter and mates. However, they also compete with some other species, such as deer and acorn weevils, for acorns. Furthermore, they are both prey for many of the same predators, such as hawks, raccoons, foxes, and weasels.

Identify the structures of the cells and the routes by which water and minerals pass through to the vascular tissue.
Answer:
Xylem
Explanation:
Xylem is a conducting tissue found in vascular plants in which most plant use to obtain water and minerals they need through their roots. Water and mineral moves from the soil to roots to stems and to leaves. The minerals such as potassium (K+), Calcium (Ca2+) travels in dissolved for in the water with various organic molecules supplied by root cells.
Water and minerals enter the root by different paths but converge in the stele, or central vascular bundle in roots.
Water conducting cells is known as tracheary elements.

Describe how gene therapy can be a social issue and give rise to moral, ethical and legal debates. Justify your response in two or more complete sentences in the essay box below.
Answer:
Gene therapy is the process or replacing mutated genes with normal genes in an attempt to heal diseases by correcting the functional code of the gene. Mutated genes can cause genetic disorders. Transformation and transfection are the two methods used to insert a normal gene into an organism. The process of transformation occurs in a laboratory. Cells are grown in the lab and then introduced to DNA that carries the gene of interest. Transfection uses a virus to introduce the gene of interest to the host cells.
Gene therapy is a relatively new biotechnology. It is very expensive and much more research needs to be done before it is perfected. Gene therapy has had the best results in the treatment of cancer. One of the ways gene therapy is used in cancer treatment is by inserting a gene that is more sensitive to treatments such as chemotherapy and radiation.tion:
