Which statement is true about blood alcohol concentration? A.Blood alcohol concentration is affected by factors such as body size and gender.B.Drinking coffee and exercising will lower your blood alcohol concentration.

C.The higher the blood alcohol concentration, the more severe the hangover will be.

Answers

Answer 1

Answer:

The statement that is true about blood alcoholconcentration is blood alcohol concentration is affected by factors such as body size and gender. So, option (A) is right.

Blood alcohol concentration (BAC) refers to the percentage of alcohol (ethyl alcohol or ethanol) in a person's blood. A blood alcohol content of 10% indicates that there is 1 part alcohol in every 1000 parts blood in the body. Alcohol content is measured in grams per 100 milliliters of blood.

Body size: People with larger bodies have more blood, thus they can consume more alcohol before it affects them negatively.

Men typically have greater BAC levels than women.

Your metabolism determines how quickly your body breaks down alcohol.

Option (B) and (C) is incorrect because drinking coffee and exercising will not lower your BAC but will make you feel more alert, even if your BAC is still high and severity of a hangover is not directly related to BAC.

Therefore, option (A) is the true statement.

The first trimester is the most critical time for an embryo or fetus.
T/F

Answers

It is true that the first trimester is the most critical time for an embryo or a fetus. This is because there are many crucial developmental stages in this time period in order to produce a viable and functional multicellular organism. Such developmental characteristics in this period include the successful formation of the notochord, the basic nerve structures and the beating heart. It is critical for such structures and organs to form properly in order to ensure subsequent developments in the fetus to form correctly and ultimately result in a successful deliverance.

Which of the following body systems helps the body regulate immune systems?A) Lymphatic
B) Endocrine
C) Circulatory
D) Digestive

Answers

The lymphatic system is the body's system which helps the body to regulate immune systems. Thus, the correct option is A.

What is the lymphatic system?

The lymphatic system is the body's system which also helps in defending the body against the germs such as viruses, bacteria, and fungi which can cause illnesses. The germs are filtered out in the lymph nodes of the body, small clumps of tissues along the network of lymph vessels. Inside these lymph nodes, lymphocytes called the T-cells and B-cells help the body to fight against infections.

The lymphatic system is an organ system in vertebrates which is part of the immune system, and complementary to the circulatory system as well. This system consists of a large network of lymphatic vessels, lymph nodes, lymphatic or lymphoid organs, and lymphoid tissues.

Therefore, the correct option is A.

Appendicitis happens due to accumulation of bacteria in the appendix, thus causing infection. When there is infection, there is always the presence of abscess and inflammation. The general treatment for appendicitis is Appendectomy. This involves the surgical removal of the appendix. This is usually performed before the appendix ruptures, if diagnosed earlier, or in certain emergency cases when diagnosed late.

How to minimize the heat loss in a chemical reaction

Answers

The usual answer (and correct) is to improve on the insulation, for example by covering the calorimeter, and using two cups, one inside the other.

Further improvements can be made
1) carrying out the experiment over as short a period of time as possible. reason; any calorimeter will loose heat, but the shorter the time allowed, the less heat will be lost.
2) Use a larger calorimeter, with greater volume of solution. reason; the greater the solvent mass requires more energy to obtain the same change in temperature. You get a smaller temp change for the same reaction, so less losses to the surroundings.
3) calibrate your calorimeter heat the same volume of pure water to a similar temperature as that which the reaction produces. Then determine the rate of heat loss over a period of time, say take temp every minute for 30 minutes, and plot a graph. This will give you a calibration curve that you can use to apply a correction for your calorimeter.
