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.

Answer:
RrYy is the genotype that is heterozygous for both seed shape and seed color. The traits here we are discussing are pea plant's seed color and shape.
Explanation:
A dihybrid cross is a cross in which two traits are simultaneously being studied. Here there are two traits under consideration that are seed shape and seed color. The seed shape can be round or wrinkled and seed color can be yellow or green. The round seed allele is dominant over yellow seed allele and the yellow color allele is dominant over green color allele.
As homozygous indicate both alleles of a gene are same in an individual and heterozygous condition indicates that both alleles of a gene in an organism are different.
Therefore the genotype of homozygous pea plants for seed color and seed shape can be RRYY or rryy respectively and genotype of heterozygous genotype will be RrYy respectively.

Answer:
Humans are gradually altering the climate and the earth's temperature through burning fossil fuels, destroying forests, and rearing animals.
Explanation:
This significantly increases the amount of greenhouse gases already present in the atmosphere, increasing the greenhouse effect and contributing to global warming.
Climate change is mostly caused by the greenhouse effect. Some gases in the Earth's atmosphere act as greenhouse glass, trapping heat from the sun and preventing it from escaping into space, causing global warming.

The cell membrane (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.
