Explanation:
Biochemistry. In biochemistry, the substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate bonds with the enzyme active site, and an enzyme-substrate complex is formed.
Answer: organ system
Explanation: the all belong to the female reproductive system
Answer: The first three years are the most critical in shaping the child's brain architecture.
Explanation: They have a direct impact on how children develop learning skills as well as social and emotional abilities.
The answers would be:
In Mendel’s crosses, the <u>recessive </u>trait is visible in the F2 generation, but not the F1 generation.
After crossing a tall pea plant with a short pea plant, all of Mendel’s pea plants were tall because it is the <u>Dominant</u><u><em> </em></u>trait.
For seed color, the F2 generation produced both yellow and green seeds because there are two different <u>alleles </u>for each gene.
If you'd like to know more, read on:
Alleles are variants of genes that control traits. There are two alleles called the dominant and recessive allele.
A dominant allele is a trait that is physically expressed even when coupled with a recessive allele. A recessive allele on the other hand is the trait that is masked by the dominant allele.
This is what happened in Mendel's crosses. He crossed a true-breeding tall plant with a true breeding short plant.
P generation
TT - Tall plant
tt - Short plant
The result in the F1 generation that consisted only of Tt plants, where the dominant allele was expressed.
T T
t Tt Tt
t Tt Tt
Then he crossed the F1 generation to produce the F2 generation.
Tt x Tt
The results:
T t
T TT Tt
t Tt tt
As you can see the resulting offsprings shows that the recessive trait occurring, tt. This means that there was a 25% chance that the off springs produced would short plants and 75% that the offsprings produced is tall. This applies also to the color of the seeds if we cross the pea plants based on the color of seeds.
Answer: option D
Reclamation of sanitary landfills occurs before the land fills is capped.
Explanation:
Reclamation of sanitary landfills is a method use to expand the municipal solid wastes sanitary landfill capacity so as to avoid high cost of purchasing another land.
Sanitary landfills is an area of land where wastes is allow to decompose or degraded chemically, physically and biologically until it is safe.
This reclamation is done before the landfills is capped so as to avoid high cost of getting another land.
