Answer;

Species diversity

Species diversity  is the umber of variety of species in the world or in a particular region.

Explanation;

-Species diversity is the number of different species that are represented in a given community.

-Species diversity is measured based on two main factors, which are; richness and evenness. Richness is a measure of the number of different kinds of organisms present in a particular area. For instance, species richness is the number of different species present. Evenness on the other hand, compares the similarity of the population size of each of the species present.

Which of the following statements is true? Choose one: A. Bacterial species use a limited number of nutrient sources. B. All bac
Lubov Fominskaja [6]

Answer:

A. Bacterial species use a limited number of nutrient sources.

Explanation:

    There are two classes of nutrients that are indispensable to bacteria: macronutrients (carbon, oxygen, nitrogen, sulfur, phosphorus and hydrogen) and micronutrients (iron, zinc, manganese, calcium, potassium, sodium, copper, chlorine, cobalt, molybdenum, selenium, magnesium, among many others). But it takes more than the nutrients for them to feed, it takes the metabolism, because it is through it that they transform what they have into food.

    The absorption of nutrients to carry out the metabolism only occurs because there are growth factors (environmental) that influence the development of the bacteria. Some examples of these factors are: light, temperature, pH, oxygen and osmotic pressure. Each organism has an optimal growth temperature, or a favorable pH to successfully carry out its metabolism. This will vary from species to species.

Please help me out with these practice questions.<br> Thank you!
Oduvanchick [21]

Answer:

1. B.

2. B.

3. A.

Explanation:

1. So, the mother does not but the father does carry the gene for polydactyly. Which means that, the offspring was born Pp and, the dominant trait (P) was exposed.

2. A heterozygous trait is one that has both allele forms (in this case, d and D. If both of the parents are Dd, the offspring will also be Dd, and therefore, he has 1/2 chance of being born deaf.

3. Both you and your spouse will be heterozygous (Ee), therefore, since unattached earlobes are dominant

3.1 When two heterozygous traits are bred, you will get the following combinations: yy, Yy, Yy and YY. Which means that your offspring had a 1/4 chance of having attached earlobes, and that is what happened.

3.2 The third option is incorrect, because when you breed 2 homozygous recessive (ee) traits, all of your offspring will be homozygous recessive (ee), which means that the parents would have to be homozygous recessive, but, they cannot since the dominant trait has applied to them.

Your digestive system is equipped with a diversity of enzymes that
nataly862011 [7]

Answer:

Enzymes are named according to <em>the reaction they catalyze</em>. Polymers are made of subunits joined together by different types of bonds, forming a macromolecule.

Hydrolases are used by the organism to catalyze the hydrolysis of polymers so they can be easily manipulated as monomers. Hydrolysis means reacting with water, water can break the bonds of different polymers turning it into its constitutive monomers.
