1. Drowning, suffocation and carbon monoxide poisoning can lead to death because they all prevent
oxygen from reaching our cells. Explain how this lack of oxygen can lead to death; be specific about how
this lack of oxygen can affect cellular metabolic processes.

Answers

Answer: Lack of energy

Explanation:

Oxygen is needed in a process known as Respiration where it is used to produce energy from glucose. This energy is what the cell uses to continue whatever functions that it carries out which are needed for the body to survive. If the cells don't get oxygen, they can't make energy and if they can't make energy, they die.

Some cells are more important than others and so will need a constant supply of oxygen. The brain for instance requires 20% of the oxygen used in the body. If the body suffers from a lack of oxygen for whatever reason, brain cells begin to die within about 4 minutes.

The brain is extremely important as it directs the body. If the cells there begin to die, the body deteriorates and the body stops engaging in certain processes due to a lack of direction from the brain. This coupled with the other cells dying around the body will lead to even more deterioration till the body dies.

the breakdown of large, complex, molecules into smaller, simpler molecules is accomplished by a process known as? A. Dehydration Synthesis B. Induced Fit C. Hydrolysis D. Lock and Key Synthesis

Answers

Answer: C. Hydrolysis

Explanation:

In the process of hydrolysis, large complex molecules such as polymers are broken down into smaller, simpler molecules like monomers.

This is done through the use of water. The molecule that neds to be broken down is reacted with water and water then breaks the bonds of the complex molecule. The hydrogen ion in water goes to a molecule of the other reactant and the OH- goes to another molecule.

if a less concentrated initial solution of sodium bicarbonate was used in beaker C would that solution require more or less bicarbonate to neurolize the acid

Answers

Answer:

It depends on the concentration of acid in the solution.

Explanation:

If the acid present in the solution is in concentrated form then the salt i. e. sodium bicarbonate is also used in concentrated form in order to neutralize the acidic solution while on the other hand, if a solution is less acidic then less concentrated amount of sodium carbonate is used to neutralize the acid solution so the concentration of sodium bicarbonate is used according to the concentrated of acid in the solution.

Explanation:

A child is born to parents that both have hypophosphatemic rickets, a disease that is caused by a sex-linked dominant trait. What is the chance that the child will have the disease if the mother is heterozygous for the trait?
75%
50%
25%
100%

Answers

Answer:

75%

Explanation:

Hypophosphatemic rickets is a disorder characterized by hypophosphatemia (low level of phosphate in the blood), defective intestinal absorption of calcium, and rickets (impaired mineralization of cartilaginous growth plates)  or osteomalacia (impaired mineralization of the osteoid) unresponsive to vitamin D. It can be inherited or acquired.

When it comes to inheritable hypophosphatemic rickets, the disorder is most often inherited in an X-linked dominant manner. This means that the gene is inherited through the X chromosome and that one dominant allele is enough to cause it.

As the mother is heterozygous for the trait, she has one dominant and one recessive allele (XHXh). The father has one X chromosome, which he inherited from his mother, and as he has the condition, the dominant allele will be present on it (XHY).

This means that, if the child is a girl, she will definitely have the disorder. Girls inherit one X chromosome from each of their parents. Even if she inherited the one with the recessive allele from her mother, she would get the one with the dominant allele from her father.

If the child is a boy, he has a 50% chance to inherit the condition. Boys inherit the Y chromosome from their father and the X chromosome from their mother. As the mother is heterozygous, he can either get the chromosome without the dominant allele or the one with it. This means that there is a 50% chance of inheriting the disorder.

If we say that there are equal chances of this couple having female and male children, when we combine these results, we get a 75% chance of them inheriting hypophosphatemic rickets.

What is the medullary index for an organism that has a medulla width of 2cm and hair shaft width 4cm? Is this organism human or animal?

Answers

Answer:

a. 1/2 b. The organism is an animal

Explanation:

a. What is the medullary index for an organism that has a medulla width of 2cm and hair shaft width 4cm?

Medullary index = diameter of medulla/diameter of hair.

Given that diameter of medulla = medulla width = 2cm and diameter of hair = hair shaft width = 4cm,

Medullary index = diameter of medulla/diameter of hair = 2 cm/4cm = 1/2

b. Is this organism human or animal?

Since the medullary index = 1/2 > 1/3 (if it is ≤ 1/3 it is human hair and ≥ 1/2 it is animal hair), it is animal hair. So, the organism is an animal.

Cell organelles are any of a number of organized or specialized structures within a living cell.

What is a cell?

A cell may be defined as the fundamental structural and functional unit of living organisms. Each living organism is made of a cell. It is responsible for each metabolic function that is necessary for the survival of living entities.

Inside each living cell, a fluid jelly-like substance known as cytoplasm is filled. This provides an environment for the cell to accomplish all sorts of its task. Within the cytoplasm, a number of various organized or specialized structures are present which are known as Cell organelles.

A cell organelle may be characterized as a small structure in a cell that is surrounded by a membrane and has a specific function.

Therefore, cell organelles are any of a number of organized or specialized structures within a living cell.

How does the final number of chromosomes in each cell compared to the starting number of
chromosomes in both cells?

Answers

Answer:

Double

Explanation:

Each haploid cell contributes half the chromosomes

Cell division is the process in which the genetic material and cytoplasm are divided to produce the daughter cells. The cell division can be mitotic or meiotic.

The division of chromosomes can be distinguished into:

Mitosis is the process of cell division in which the number of chromosomes in the parent cell is similar to the daughter cells. The mitotic division occurs in the somatic cells of an organism.

The meiotic division is the process in which the number of chromosomes in the parent cells is halved. The meiotic division occurs in the reproductive cells of the sexually reproducing organisms.

Thus, the final number of chromosomes will be 46 in the mitotic division, whereas, in the meiosis, it will be half the parental chromosomes.
