A ________ is a rigid layer that surrounds a plant cell, providing structural support.A. chloroplast
B. nucleus
C. cell wall
D. cell membrane

Answers

Answer 1
Answer:
The cell wall is the part of the cell whose purpose is to provide structural support to the cell. This is located outside the cell membrane. This part can be flexible or rigid. The purpose of cell wall acts like that of the skin of the human body. answer hence is C.

How do the quantities of ATP formed during aerobic and anaerobic respiration compare? A. Two times more ATP is formed during aerobic respiration than during anaerobic respiration. B. Four times more ATP is formed during aerobic respiration than during anaerobic respiration. C. Eight times more ATP is formed during aerobic respiration than during anaerobic respiration. D. Eighteen times more ATP is formed during aerobic respiration than during anaerobic respiration.

Answers

Answer:

The correct option is D. Eighteen times more ATP is formed during aerobic respiration than during anaerobic respiration.

Explanation:

Aerobic respiration can be described as the process of respiration taking place in the presence of oxygen. This process makes a lot more energy as compared to anaerobic respiration.

Anaerobic respiration can be described as the process of respiration taking place in the absence of oxygen. This process is one of the earliest reactions that occurred in organisms since the formation of life.

The process of aerobic respiration releases 38 ATP per glucose whereas the process of anaerobic respiration releases 2 ATP molecules per glucose. Hence, the ATP formed during aerobic respiration is approx 18 times more than the anaerobic respiration.

Which of the following affects the intensity of the combustion reaction ifs Bunsen burner ? A.)the temperature in the laboratory B.)the position of the Bunsen burner
C.)the amount of air that mixes with the gas stream

Answers

The amount of oxygen that mixes with the gas stream effects the intensity of the combustion reaction in Bunsen burner. The correct option among all the options that are given in the question is the last option or option "C". The increase in the amount of air mix will result in a flame that has a higher temperature.

Answers

The structure that secretes the neurotransmitter is the synapse. The synapse is where these neurotransmitters are located. Neurotransmitters are organic chemicals formulated by the nerve cells which enables and triggers some behavioral and cognitive, even emotional dispositions. These are activated according to specific function.  

A patient is found to be suffering from a bacterial infection. Which genetically engineered medicine is most likely to be used to help this patient?

Answers

The treatment for this patient will be with antibiotics, the most common being penicillin. This drug pioneered the treatment of bacterial infections by successfully destroying the bacterial cell wall of microorganisms. Discovered by Alexander Fleming in 1928, penicillin revolutionized the history of medicine, encouraging new scientific studies and saving the lives of many patients.

The most common antibiotic for infections is penicillin.

Female salmon drop their eggs at the bottom of the river, and then the male salmon come by and release sperm over them. This is called _____. external fertilization internal fertilization conjugation pollination

Answers

Answer: external fertilization

Explanation:

External fertilization is the process of fertilization in which the male sperm cells fuses with the female egg cells outside the body of the female. This type of fertilization is used by the organisms which live in the water body.

The salmon is a fish species which utilizes external fertilization. In the case of salmon, the female salmon drops the eggs in the bottom of the water which are fertilized by male salmon after secreting their sperms over these eggs.

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.
