I found the attached image on the internet and it really helps complete this exercise.

First question:
In the presence of an enzyme, the course of the reaction is shown by the red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.

Second question:
The activation energy is represented by line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.

Alleles can be described as 1. dominant 11. recessive III. codominant IV. partially dominant V. incompletely dominant O A. I, II
joja [24]

Answer:

A. I, II, III, and V only

Explanation:

In genetics, an allele refers to the specific form of a gene, which encodes traits. These alleles are usually in pairs in a diploid organism i.e. an organism with two sets of chromosomes. According to Gregor Mendel,

- An allele can either be DOMINANT when the allele masks the phenotypic expression of its allelic pair while the allele that is masked is said to be RECESSIVE.

- Two alleles can also be CO-DOMINANT when the two alleles are neither dominant or recessive over one another but are simultaneously expressed in that particular gene.

- Alleles can also be INCOMPLETELY DOMINANT when one allele is not completely dominant over the other, hence, forms a third intermediate phenotype when in combination with the second allele i.e. in an heterozygous state.

Based on this, an allele can be dominant (I), recessive (II), codominant (III), and incompletely dominant (V).

Granite rock is light in color. Which feature directly contributes to this color?
kondaur [170]

Answer: the amount of silica minerals in granite

Explanation:

Usually, 70-77 percent silica, 11-13 percent alumina, 3-5 percent potassium oxide, 3-5 percent soda, 1 percent lime, 2-3 percent total iron, and less than 1 percent magnesia and titania are the chemical composition of granite. Rhyolite is another kind of volcanic rock with a similar or equivalent chemical composition and mineralogy. Due to high precense of silica the color of granite appears lighter.

How do you know if a trait on a pedigree is recessive?
Reika [66]
An easy way to tell is if the trait is or isn’t in every generation. If a trait skips a generation, it’s most likely recessive.

Scientists can use cells from one organism to produce a genetically identical organism by
dlinn [17]
Scientists who do this are doing what is considered to be and called cloning. Cloning is exactly this - taking cells from one organism and trying to produce and recreate an identical (from a genetic perspective) organism.

This can be done in a routinely fashion but there are serious ethical considerations nowadays.
