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.

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:

j

Explanation:

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

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%.

When and where would you expect to find the highest rate of primary productivity

Answers

Answer: Net primary productivity is the amount of gross primary productivity remaining after respiration, which is about 40 and 85 percent. Sloughs and marshes, as well as tropical rain forests, possess the highest rates of net primary productivity; deserts have the lowest.

Explanation:

I explained on the top-

The highest rate of primary productivity in terrestrial environments takes place in swamps and marshes and in tropical rainforests, and in aquatic environments it takes place in algal beds, estuaries, and reefs.  

• In ecology, primary productivity refers to the rate at which conversion of energy to organic substances takes place by the photosynthetic producers that attain energy and nutrients from the sunlight, and chemosynthetic producers that attain chemical energy via oxidation.  

• The majority of the energy assimilated by plants via the process of photosynthesis is not stored as organic substance, however, is utilized at the time of cellular respiration.  

• In the process, the organic components like proteins, carbs, and fats are dissociated to provide energy in the form of ATP for the metabolic needs of the cells.  

• The energy not utilized is stored in the tissues of the plants for future use and is known as the net primary productivity.  

• The highest net primary productivity in terrestrial environments takes place in marshes and swamps and in tropical rainforests, and in aquatic environments it takes place algal beds, estuaries, and reefs.  

These environments are mainly critical for the sustenance of global biological productivity.

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.

Claim: This process uses expensive fertilizers and pesticides to grow pest free crops which may be produced in excess. Explain the reasons why people would go against growing wheat this way.

Your answer: Here are 3 reasons that go against growing wheat this way.

1. The fertilizers and pesticides are expensive and cost farmers a lot which takes away from the revenue that farmers make from growing the crops in the first place.

2. Other then fertilizers and Pesticides its a lot of work as you can see on the chart throughout the year there are many things you must do too keep crops bug free and pest free this reason I'm explaining says that taking and doing all of this work for not pests/bugs is too much and not needed.

3. Fungicide Is needed a lot and incredibly expensive when you used/spray it on crops that much and point goes a lot more for large crops too.

If these reasons don't work, find factors that or counterclaims that go against this method of harvesting wheat. (This is what your supposed too do)

Adults produce gametes through a type of cellular reproduction called mitosis. The process of a sperm cell and an egg cell fusing together is called fertilizationand produces a zygote. As a zygote undergoes rapid cell division to develop into an embryo, fetus, and eventually baby, the type of cellular reproduction being used is . As a baby grows into an adult, the type of cellular reproduction used is mitosis.

Answers

Answer:

Mitosis.

Explanation:

Mitosis is the type of cellular reproduction which is used in order to develop an embryo, fetus, and eventually baby. In mitosis type of cell division, the parent and mature cells divides into two daughter cell. This type of cell division occurs in somatic or body cells whereas meiosis type of cell division occurs in the sex cells which produces four daughter cells from a single parent cell.

which feature of stem cells enable them to replace cells in tissues such as skin?

Answers

That is right!!!!! Hope that helped

The feature of stem cell which enable them to replace cell in tissues are that they can divide indefinitely to generate new cells and they can convert into the different types of cells that make up the body as they divide.

What is a stem cell ?

A stem cell is a cell that has the unique capacity to grow into different types of cells in the body.

They may be utilised in the future to replace cells and tissues that have been damaged or destroyed owing to illness.

Stem cells are classified into three types which are Embryonic stem cells, Adult stem cells, Induced pluripotent stem cells.

Embryonic stem cells provide new cells to an embryo as it grows and develops into a newborn.

Adult stem cells generate new cells as an organism matures and replace damaged ones.

Induced stem cells are stem cells created in the laboratory by scientists.
