In humans, brown eyes are dominant to
blue eyes. What is the probability
that two heterozygous brown-eyed
parents will have a child with blue
eyes?
J. 25%
K. 50%
L. 75%
M. 100%

Answers

Answer 1

Answer:

j

Explanation:

since brown eyes are more dominant than blue eyes chances of it is 3/4

Answer 2

Answer:

The answer is J. 25%.

Explanation:

In this problem, we know brown eyes are dominant to blue eyes.  We can let the dominant allele for brown eyes be represented by "B" and the recessive allele for blue eyes be represented by "b".  Since it is given that both parents are heterozygous, we know that they must have the genotype Bb.

When two Bb individuals are crossed, the offspring will be 1 BB : 2 Bb : 1 bb, or 3 brown : 1 blue ratio.  Therefore, 1/4 of the offspring will have blue eyes, which represents 25%.  Thus, the correct answer is choice J, 25%.

Hope this helps!

5. Our nervous system and our skeletomuscular system help us react to stimuli. Give one example on how this helps us maintain homeostasis.

Answers

Answer

The nervous and skeletomuscular systems help maintain homostasis by regulating respiration.

Explanation:

The brain stem, consisting of the pons and medulla, represent the main respiratory center.   According to Wikipedia, "an increased level of carbon dioxide in the blood, or a decreased level of oxygen, will result in a deeper breathing pattern and increased respiratory rate to bring the blood gases back to equilibrium."

This is an example of a homostastic response controlled by both of the organ systems referenced above.

HELP! What evidence indicates that many psychological disorders, such as schizophrenia and developmental
disorders, are biologically and not environmentally based?

Answers

Answer:

Schizophrenia and developmental disorders are traced genetically, and the gene will be found in the biological parents of the person with either schizophrenia or developmental disorders.

Explanation:

Although Schizophrenia can be triggered by environmental factors, or the 'nurture' of childhood development, a person who is not predisposed genetically to schizophrenia will not get the psychological disorder. The same is to be said about developmental disorders such as Autism and ADHD, it is hereditary.

For citation of evidence, I recommend talking about prenatal development, and how toxic substances can alter the development of a fetus, which is proven to lead to some developmental disorders, such as Fetal Alcohol Syndrome.

Answer:

Schizophrenia and developmental disorders are genetically connected, and the gene will be found in either the individual's biological parents or the person suffering from schizophrenia or developmental abnormalities.

Deforestation occurs when large Amounts of trees are cut down and not replaced which of the following would result from deforestation


A. Decrease carbon in the atmosphere
B. Increased carbon in the atmosphere

Answers

Answer:

The correct answer is (B).

Explanation:

Deforestation occurs when large Amounts of trees are cut down and not replaced, which of the following would result from deforestation...

Increased carbon in the atmosphere

This statement is true because when trees become less abundant, the amount of oxygen being released into the atmosphere by trees via photosynthesis.

The circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.

What is Deforestation?

Deforestation may be defined as the process of cutting down or eliminating trees in large numbers from our surroundings. This activity generally happens due to industrialization, wood extraction, urbanization, etc.

When the number of trees remains less in the environment due to deforestation or any other activity, the level of carbon dioxide in the atmosphere typically rises.

This is because carbon dioxide is considered the reactant of photosynthesis that is utilized by the plants along with water in the presence of sunlight and converted into oxygen.

But when the number of plants decreases, the level of carbon in the atmosphere increases, and the level of oxygen in the atmosphere decreases.

Therefore, the circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.
