One hypothesis can be that there is an effect of aeration on the growth of roots of bean seedlings.

Control group: has "no aeration"
Experimental group: has the aeration treatment

Dependent variable: growth can be measured in the length of the seedlings probably in centimeters



Researching is composed of various explorations in utilizing the scientific method in the process. It also, answers any scientific inquiry with the use of scientific method. Research enables and promotes the scientific community at a larger scale. Contributing and collaborating knowledge all-over the people and persons in science. Researches play a big role in everyone’s academic identity because

Genetic drift simulation:
Airida [17]
Unlike natural selection, genetic drift does not depend on an allele's beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.

How many variations do you observe?
masya89 [10]

Answer:

Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning and mental ability, and other obvious or measurable characters.

chromosomes or by differences in the genes carried by the chromosomes. Eye colour, body form, and disease resistance are genotypic variations. Individuals with multiple sets of chromosomes are called polyploid; many common plants have two or more times the normal number of chromosomes, and new species may arise by this type of variation. A variation cannot be identified as genotypic by observation of the organism; breeding experiments must be performed under controlled environmental conditions to determine whether or not the alteration is inheritable.

Genotypic variations are caused by differences in number or structure of Environmentally caused variations may result from one factor or the combined effects of several factors, such as climate, food supply, and actions of other organisms. Phenotypic variations also include stages in an organism’s life cycle and seasonal variations in an individual. These variations do not involve any hereditary alteration and in general are not transmitted to future generations; consequently, they are not significant in the process of evolution.
