This imaging tool can tell you the speed and direction of blood flow.a.ultrasound
b.CT
c.MRI
d.none of the above

Answers

Answer 1

Answer: The correct answer is letter a. Ultrasound. An ultrasound machine allows doctors to study or monitor a patient's internal organs, and it is usually used in pregnant patients to monitor their developing fetus, in this case the ultrasound can also be used to tell a person the speed and direction of his or her's bloodflow, because the ultrasound machine can be used to study a person's heart or blood vessels

Answer 2

Answer:

Answer:

Ultrasound

Why do cells use fat and starch for long-term energy storage instead of ATP molecules?

Answers

Cells use fat and starch for long term energy storage instead of ATP molecules because it is hard to breakdown fat in a very short time while ATP can be broken down in a very short time. ATP is mainly used while doing short bursts of exercises. Fats have a very strong bond of molecular chains and this makes it hard to breakdown quickly.

Answer:

c-ATP is used for short-term energy and to build molecules of starch and fat.

which of the following explains the fact that animals that differ greatly in complexity can have similar numbers of genes?

Answers

Each organism functions and is based on the structure of their genes which shapes their genotype, the traits of the genes and the phenotype, the external traits and characteristics. Hence, animals with complex structures and even simple ones has the similar fundamental component -genes. Genes, however, can vary in distinct number of ways. In complex organisms they may have the sophisticated structures but the genes that holds those basic structure remains identical hence same number of genes.

Which mixture of gases is thought to have made up Earth's early atmosphere? A. methane, oxygen, hydrogen, water vapor B. carbon dioxide, nitrogen, oxygen, ozone C. hydrogen, water vapor, ammonia, methane, carbon dioxide D. ozone, water vapor, carbon dioxide, ammonia

Answers

The answer is D. ozone, water vapor, carbon dioxide, ammonia.

We really don't know what early earth's atmosphere contained. We can only speculate. Likely, it contained methane at some point, along with other noxious gases from erupting volcanoes.

Which area of fat deposition is more closely associated with disease? 1) Waist fat 2) Buttocks fat

Answers

Answer: Waist fat

Explanation:

Waist fat (abdominal fat) is more closely associated with the risk of certain diseases compared to buttocks fat. Excess fat deposition around the waist, often referred to as visceral fat, is particularly concerning from a health perspective. Visceral fat is associated with an increased risk of various health problems, including:

1. **Cardiovascular Disease:** Visceral fat is strongly linked to an increased risk of heart disease. It can lead to high blood pressure, elevated cholesterol levels, and an increased risk of developing atherosclerosis (the narrowing and hardening of arteries).

2. **Type 2 Diabetes:** Excess visceral fat is a major risk factor for developing type 2 diabetes. It can contribute to insulin resistance, where the body's cells do not respond effectively to insulin, leading to high blood sugar levels.

3. **Metabolic Syndrome:** Metabolic syndrome is a cluster of conditions that increase the risk of heart disease, stroke, and type 2 diabetes. It includes factors like abdominal obesity, high blood pressure, elevated blood sugar, and abnormal lipid profiles.

4. **Fatty Liver Disease:** Visceral fat accumulation is associated with non-alcoholic fatty liver disease (NAFLD), which can progress to more severe liver conditions.

5. **Certain Cancers:** Some studies suggest that excess abdominal fat may increase the risk of certain types of cancer, including colorectal cancer.

In contrast, buttocks fat, or subcutaneous fat in the gluteal region, is considered less metabolically active and less strongly associated with the same health risks. While having excess fat in any part of the body can lead to overweight or obesity, the distribution of fat, with a particular emphasis on abdominal fat, plays a significant role in determining its impact on health.

Final answer:

Waist fat or abdominal fat, also known as visceral fat, is more closely associated with diseases compared to buttocks fat. Having a larger waistline can increase the risks of cardiovascular disease, Type 2 diabetes, and other health issues. While fat stored in the buttocks area is considered less dangerous as it doesn't surround vital organs, any excessive fat can pose health problems over time.

Explanation:

The accumulation of fat in the body and its corresponding location has been closely linked with disease risks. More specifically, waist fat is generally more closely associated with various health issues when compared to buttocks fat. It's important to establish that the human body tends to store excess fat in different areas based on factors like genetics, metabolism, and lifestyle.

According to data and studies, having a larger amount of waist fat can potentially lead to consequences such as an increased risk of cardiovascular disease, Type 2 diabetes, and other health conditions. This kind of fat, known as visceral fat, often accumulates around the organs in our abdomen and poses a higher threat than fat stored in other areas of the body.

Supposedly, fat stored in the buttocks area, or subcutaneous fat, doesn't bear the same level of health risks as waist fat because it doesn't surround vital organs. However, we must underline that excessive fat, no matter where it's located, can still lead to health issues over time, so maintaining a balanced lifestyle remains crucial.
