nicotine, the embryo is put at risk because these toxins can

1) diffuse from the mother's blood into the embryo's

blood within the placenta

2) enter the embryo when it eats

3) transfer to the embryo since the mother's blood

normally mixes with the embryo's blood m the placenta

Answers

Answer:

Explanation:

Fast-twitch muscle also uses glycolysis to produce energy, but it skips harvesting energy from pyruvate, a process that takes oxygen. Instead, pyruvate gets converted into a waste product, lactic acid, and released into the bloodstream

Answer: Lactic acid is produced in your muscles when you perform strenuous exercise. It’s produced mainly in muscle cells and red blood cells when the body breaks down carbohydrates for energy when oxygen levels are low. These levels decreases during intense exercise or when a person has an infection or disease.

Answers

The correct option is D.) 1, 3, and 6 because pressure is the changing factor in Gay-Lussac's Law, the constant factor in Boyle's Law, and the changing factor in Charles's Law.

Gay-Lussac's Law states that the pressure of a given quantity of gas held at constant volume is directly proportional to the Kelvin temperature which means the pressure of a gas increases as the temperature increases, and decreases as the temperature decreases.

Boyles Law states that the pressure of a gas is inversely proportional to its volume that means as the volume of a gas increases, the pressure of the gas decreases, and vice versa.

Charles's law is a basic physical law that states that the volume of a given amount of gas at a constant pressure is directly proportional to its absolute temperature. This means that when the temperature of a gas increases, its volume also increases, and vice versa.

Indicate whether the statements below are TRUE or FALSE.

1. You work with two sugars. Glucose (MW = 180 Da) and Sucrose (MW= 342 Da). You make various solutions of each sugar separately and compare them. When you compare two 1-liter solutions containing these sugars at a 10mM concentration, there are more molecules of sucrose in 1 liter because its MW is higher than that of glucose.

2. When you compare two solutions at the same percentage concentration (e.g. 1%), the molarity (= concentration in mole/liter) is higher for glucose because the molecular weight of glucose is lower.

3. When you have 1 liter of a solution containing 90g of glucose, you must use 171g of sucrose to make a 1-liter sucrose solution with the same molar concentration.

Imagine that fully functioning kidneys have been successfully created through bioengineering. What data analysis would measure the effectiveness of bioengineered organs in improving access to organ transplants among diverse groups of people, and what evidence would be needed to demonstrate that bioengineered organs have improved access

Answers

Answer:

The correct data analysis and evidence is:

Analysis: Compare the percentage of different ethnic groups who receive kidney transplants before and after bioengineered kidneys are available.

Evidence: A greater percentage of African Americans, Asians, and Pacific Islanders, and Hispanic/Latinos receive transplants after bioengineered kidneys are available compared to before

Explanation:

Bioengineered organs may be used to repair organs that have been destroyed. If the bioengineered organs are identical to the initial ones, transplantation rejection may be reduced.

So, to assess the effectiveness of organ donation adoption in people of various ethnicities, we should compare the percentage of people of various ethnicities receiving organ transplants before and after bioengineered organs became viable, and look for signs of a higher percentage of people of various ethnicities receiving organ transplantation after bioengineered organs became available.

7. Once anaerobic respiration takes place, are the effects permanent? Why or why not?
If a tutor can give me the answer that would be very helpful

Answers

No, the effects can wear off which is why we breath constantly. When anaerobic respiration takes place it happens because of the lack of oxygen. So in order to make up for the lack of oxygen in that time anaerobic respiration repeats its cycle.

Once anaerobic respiration takes place, the effect is not permanent. When enough oxygen is available, the cell uses the oxygen to oxidise the glucose.

What is anaerobic respiration?

In anaerobic respiration, oxygen is not used for the oxidation of glucose, and as a result, very little energy is produced. Glucose undergoes glycolysis and forms pyruvate. Without the presence of oxygen, lactic acid and ethanol are formed from the glucose.

When a person runs too fast, he can't breathe properly, and muscle cells don't get enough oxygen. Due to this, glucose undergoes anaerobic respiration and forms lactic acid. As less energy is produced, more is required by the cell, and a muscle cramp takes place.

When the person gets enough oxygen, this process will reverse as the cells get enough oxygen to completely oxidise the glucose. Due to the lactic acid formation in muscles, the blood pH declines, making the blood acidic.

Hence, when enough oxygen is available, this effect of anaerobic respiration will reverse.

Answers

Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.

What is the purpose of the theory of evolution?

The Theory of Evolution states that it is the environment, through natural selection, that determines the importance of the individual's characteristic or its variations, and the organisms best adapted to this environment have a greater chance of survival, leaving a greater number of descendants.

With this information, we can conclude that Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.
