A particular recessive genetic disorder is polygenic. It is caused by 2 separate, unlinked genes (Genes A and B). To have the di

sorder, a person must be homozygous recessive for BOTH of these genes. A mother is heterozygous for Gene A and homozygous recessive for Gene B. The father is heterozygous for gene Gene A and homozygous dominant for Gene B. If they have 2 children, what is the probability that 1 of them will have this disorder

Answer:

1/4

Explanation:

1-Mother:

The probability to pass the disorder to her progeny is: 1 x 1/2 = 1/2

Father:

2-The probability to pass the disorder to his progeny is: 1 x 1/2 = 1/2

Therefore, the probability to have the disorder is equal to the product of both independent events, i.e., 1/2 x 1/2 = 1/4 or 25%

PLEASE HELP!! Identify a specific environmental factor that will cause a response to living things, and describe how this factor
jasenka [17]

Answer:

A specific environmental factor that will cause a response to living things will be light from the sun.

Explanation:

An enhanced amount of light from Sun will cause the plants to have enhanced photosynthesis. Photosynthesis can be described as a process by which plants use light energy from the sun to convert carbon dioxide and water into sugar (food) and oxygen.

In animals, enhanced amount of light from the sun will cause sweating and vasodilation.

The process of photosynthesis won't occur in animals and the process of sweating won't occur in plants.

1) A plant gets 628.3 kcal of energy from the sun, what energy is left at the quartenary consumer level?
Jobisdone [24]

1. The energy left in the Quaternary consumer level is 0.06283 kcal.

2. 0.65 units of energy  is still available at the tertiary consumer level.

<u>Explanation:</u>

Energy flow in an ecosystem obeys the ten percentage law According to which ten percentage of energy from a trophic level gets transferred to the next trophic level. In the given question plants belong to the trophic level , producers  and it transfers 10 percentage of its energy to the primary consumer level.

In the question 1 the energy that the producers have is 628.3 kcal. Ten percentage of this i.e 62.83 kcal gets transferred to the primary consumer level. Ten percent of that which is 6.283 kcal gets transferred to the secondary consumer level.  Ten percent of 6.283 kcal i.e  0.6283 kcal energy is transferred to the tertiary consumer level.

Thus the Quaternary consumer level gets ten percentage of 0.6283 kcal i.e 0.06283 kcal. In question B the initial energy at the primary level is 650 units. Ten percentage of 650 i.e 65 units reach the primary consumer  level. Ten percentage of this 65 units then reaches the secondary consumer level. Thus the secondary consumer level has ten percent of 65 i.e 6.5 units of energy.  

So the energy that reaches the tertiary consumer level is ten percentage of 6.5 i.e 0.65 units.
