List three environmental factors that could cause certain neurological conditions and indicate the neurological disease caused by each one.I did this:
Three environmental factors that could cause certain neurologist conditions:
- Radiation: This may produce Cancer in the brain, making it spread.
- Genetic Mutation: This has many symptoms, it can cause autism, Down syndrome, strokes etc.)
- A lot of Drugs/Alcohol: This may cause long term diseases, delirium, and dementia.

Is it okay?

Answers

Answer:

Three environmental factors can be:

1.Ionizing radiation: cancer in the bone marrow or stomach

2.Solar radiation: skin cancer

3. Electromagnetic fields: induction of cataracts of the eyes.

Explanation:

1. Radiation sickness occurs when exposed to very high doses of ionizing radiation. It may be acute or chronic. The risk for cancer is dose dependent and an accumulation effect begins if the doses are very low.

2. Skin cancer is malignant that is caused by the uncontrolled division and growth of skin cells, with the ability to invade healthy tissues.

3. The thermal effects of electromagnetic fields produced by radar waves include the increase in body temperature by more than 1ยบ C. Its effects include the cataracts of the eyes, and physiological and thermo-regulatory responses as the body temperature increases .

What term defines questions about what people should do with knowledge in biology that cannot be answered using the scientific method?

Answers

Answer:

The correct answer is - bioethics.

Explanation:

The study of the issues related to the ethics emerged from the knowledge of the biology-related studies and other branches and their application. This is the study that is concerned with how one should use and apply biological knowledge.

Bioethics is based on what is moral to do with or believes of the peoples. It affects the use of several biological processes to perform such as cloning, stem cell-related researches and many more.

Thus, the correct answer is - bioethics.

Why wont Neon bond with anything else on the periodic table of elements?

Answers

because it belongs to group 0 the noble gases. Neon has a complete outer shell, a stable electronic configuration, thus it can exist as a monoatomic gas, and as it cannot form ions it cannot bond with a metal. It is unreactive

Which of the following describes the properties that allow capillaries to exchange gas between blood cells and surrounding tissue? a. Capillaries are short vessels with thin walls that create strong pressures forcing gas-infused blood to diffuse to the surrounding tissue.
b. Capillaries have thin walls and narrow diameters so that blood cells come close to the thin walls, across which gases can diffuse to surrounding tissue.
c. Capillaries have valves along their walls that allow blood cells to move through them to surrounding tissue, where gas exchange can occur.
d. Capillaries regulate the pressure of blood within them so that a steady stream of gas-infused blood cells passes into the surrounding tissue.

Answers

The answer is b. Capillaries have thin walls and narrow diameters so that blood cells come close to the thin walls, across which gases can diffuse to surrounding tissue.

Capillaries are the smallest of all blood vessels. They have very narrow diameters (5-10 micrometers) and thin walls. All of this allow the blood cells to come close to the walls and cross them so gases diffusion to surrounding tissue can occur.

Through the process of elimination:
- a. is not the right choice because thin walls could not persist strong pressure.
- c. is not the right choice because capillaries do not have valves like veins do.
- d. is not the right choice because capillaries are that small they cannot regulate the blood pressure within them.

Explanation:

suppose a cell wishes to make a protein that has 100 amino acid. How many water molecules will be created in the making of this small protein?

Answers

The answer is 99.

Amino acids contain a carboxyl group (carbon-containing) and an amino group (nitrogen containing). Proteins are made by forming peptide bonds between the carboxyl and amino group of amino acids.
If a protein is made of 100 amino acids, that means there are 99 peptide bonds (because the last, 100th amino acid will not bind the next (101st) amino acid). For each peptide bond that is created, one oxygen atom and two hydrogen atoms are taken. Therefore, one water molecule is created for each peptide bond. If there are 99 peptide bonds, 99 water molecules are created.

A star at the end of its life-cycle, composed of mostly carbon, is a A. nova.
B. giant.
C. red dwarf.
D. white dwarf.

Answers

A star at the end of it's life cycle is called a white dwarf (answer D). The order of life in the answer choices given is giant, red dwarf, white dwarf and nova. The nova, while the final stage is actually the explosive death of a star. The white dwarf state is a small, hot star that is that is dense in composition and composed of mostly carbon and oxygen. 

Answer: D. White Dwarf
