Colt1911 [192]3 years ago
6 0
1. Non random mating
                                    In genetic equilibrium individuals must mate at random. However, in many species, individuals select mates based on heritable traits, such as size, strength, or coloration, a practice known as sexual selection.

2. Small population size
                                        Genetic drift does not have major effects on large populations but can affect small populations. Thus evolutionary change due to genetic drift happens more easily in small populations.

<span>3. Immigration or Emigration
                                                 Individuals who join a populations may introduce new alleles into the gene pool. Likewise individuals who leave may remove alleles from the gene pool. Any movement of individuals into (immigration) or out of (emigration) a population can disrupt genetic equilibrium, a process know as gene flow.

4. Mutations
                   Individuals who join a populations may introduce new alleles into the gene pool. Likewise individuals who leave may remove alleles from the gene pool. Any movement of individuals into (immigration) or out of (emigration) a population can disrupt genetic equilibrium, a process know as gene flow.

5. Natural Selection
 if different genotypes have different fitness, genetic equilibrium will be disrupted, and evolution will occur.</span>

True or false? The liver is a component of the alimentary canal.
Oksanka [162]
<h2>False  </h2>

Explanation:

Alimentary canal components include mouth, pharynx, esophagus, stomach, small intestine and large intestine whereas liver is a component of the accessory digestive system

  • The liver is a large organ that is located in the upper right portion of abdomen, beneath the diaphragm
  • The liver has two large sections, called the right and the left lobes and the gallbladder sits under the liver, along with parts of the pancreas and intestines
  • The liver and these organs work together to digest, absorb, and process food
  • The liver's main role is to filter the blood coming from the digestive tract, before passing it to the rest of the body
  • The liver also detoxifies chemicals and metabolizes drugs
  • The liver secretes bile that ends up back in the intestines and also makes proteins important for blood clotting and other functions

The human body stores chemical energy from digested food some of the chemical energy is converted into mechanical energy when th
babymother [125]

Answer:

<em>Digested food is a source of potential energy</em>

Explanation:

When we digest food, the molecules of the food are broken down into smaller compounds. Chemical energy is released due to this process. Chemical energy can be used to form glucose and fat. These molecules store energy in them. When energy is required by the body, the glucose molecules can be converted into ATP and hence give energy. This energy can be used for various purposes such as it can be converted into mechanical energy for muscle movements.
