Answer:

1. Sexual Reproduction

2. Genetic variations

Explanation:

Human reproduces through sexual reproduction. Sexual reproduction is the process of production of new progeny by the formation of male and female gametes (sperms and egg respectively) and fusion of gametes. During gamete formation, crossing over adds new gene combinations to the gametes. The genetic variations make the progeny of sexual reproduction different from each other and from the parents.

Select the correct answer. which sentence describes an object that has kinetic energy? a. a seagull sits on top of a fence post.
ololo11 [35]

" a boat sails across the ocean" possess Kinetic energy. hence option d is correct.

<h3>What is Kinetic energy?</h3>
  • Chemical energy, thermal energy, electromagnetic radiation, gravitational energy, electric energy, elastic energy, nuclear energy, and rest energy are only a few of the many different types of energy that exist. Potential energy and kinetic energy are the two basic categories that can be used to group them.
  • An object's kinetic energy is what drives its motion. Kinetic energy can be converted into other types of energy and transported between objects.
  • The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.

Answer:

B. MacConkey is both a differential and a selective medium.

Explanation:

Selective media contain the ingredients that allows for the growing of specific microbes while inhibiting the others.

For example MacConkey media facilitate the growth of gram negative bacteria and inhibit the growth of gram positive bacteria. That why E. coli and P. mirabilis grew on the media because these are gram negative and S. saprophyticus does not grew being gram positive.

Differential media allow to differentiate between selected microbes by visual observation.

For Example MacConkey media differentiate between organisms that can ferment lactose to the organisms that can't ferment it. That why E. coli appeared pink on the media because it can ferment lactose while P. mirabilis appears colorless because it usually cannot ferment lactose.
