Answer:
Fertile soils teem with life. Porous loamy soils are the richest of all, laced with organic matter which retains water and provides the nutrients needed by crops. Sand and clay soils tend to have less organic matter and have drainage problems: sand is very porous and clay is impermeable.
Two alleles expressing exactly the same information for a trait are described as homozygous.
An individual is homozygous for an allele if the two alleles are identical. Two normal alleles or two alleles with the same variation can both be present in a homozygous genotype. When an organism is homozygous, it signifies that it possesses two copies of the same gene allele.
If an organism possesses two copies of the same dominant allele, it is said to be homozygous dominant, and if it possesses two copies of the same recessive gene, it is said to be homozygous recessive. For instance, there are two variants of the gene for seed shape in pea plants: one form (or allele) for round seed shape (R), and the other for wrinkled seed shape (r).

Answer:
They are reservoirs of carbon in the carbon cycle.
Explanation:
A biogeochemical or nutrient cycle has two major components:
- the reservoirs of the biogeochemical or nutrient, and
- the processes involved in cycling the biogeochemical or nutrient between the reservoirs.
Air is a reservoir of largely inorganic carbon (as carbon dioxide) while water and soils are reservoirs of both organic (e.g. dead decomposing organisms and hydrocarbons) and inorganic forms of carbon (e.g. carbon-containing minerals such as limestone, calcium carbonate).
Answer:
The answer is below
Explanation:
In this situation, Lisa would need to at least test two of her family members. Where one group would grow their hair naturally, this would be labeled or referred to as "Control Group."
On the other hand, the second group would use Rogooti, this group would be labeled or referred to as "Independent variable."
Finally, she would need to estimate the length of hair grown over a given period of time which will be termed as "Dependent variable".
