Answer:
<u><em>definition;</em></u>
enzymes are protein that catalyze speed up the biochemical reactions and are not changed during the reaction . the molecules at which enzyme work are called <em>substrate </em> and enzymes convert them into different molecules called products.
<em><u>benefits of enzyme in digestion ;</u></em>
enzyme lower the activation energy in several ways. they may alter the shape of substrate and reduce the requirement of activation energy . enzyme may also lower activation energy by bringing substrate in correct orientation to react . enzyme break down <em>carbohydrates, lipids and proteins </em>which are component of human food .In digestion larger molecules are broken into smaller molecules like amino acids ,simple sugars ,fatty acid ,vitamins ,salts and water to provide to cells. these molecules are a part of larger molecules like protein ,polysaccharids and lipids . enzymes like amylaze, lypase ,salivary amylase, pepsin ; it is a very strong protein digesting enzyme it is released in its inactive form pepsinogen which is converted into pepsin with the help of H-C-L hydrochloric acid it takes part in digestion in stomach
Not sure what you mean but here's what i think
1.They are substrate-specific, because it's a lock-and-key mechanism.
2. They are re-used
3. They can catalyze reactions
4. They decrease activation energy
5. They are proteins by nature.
Answer:Polaris is directly overhead (i.e. at zenith) at the North Pole and at the horizon for an observer at the equator. The rule of thumb for the altitude of Polaris is that the altitude of Polaris equals your latitude on Earth.

Corrected Question:
The picture shows the dihybrid cross of 2 guinea pigs.
1. What is the genotype of the parents?
2. What is the phenotype of the parents?
3. What is the genotype of their baby guinea pig (in the empty box)?
a. BbRr - black rough fur
b. Bbrr - black smooth fur
c. bbRr- white rough fur
d. bbrr - white smooth fur
Answer:
Genotype of parents is BbRr as seen in the cross.
Phenotype of the parents is black rough furred.
The genotype of the baby in the empty box is bbRR.
Option D
<h3><u>
Explanation:</u></h3>
This representation of the genetic crossing is called as Punnet square, after the name of the scientist who discovered this process to denote the probability of finding the required genotype in a statistical way.
Here both the parents are heterozygous black and rough furred, with the genotype of BbRr.
So the gametes from the parents are = BR, Br, bR, and br from both the parents which are represented in the Punnet square.
Thus we can get 16 types of genetic combinations among the offsprings.
