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?
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.

Answer: I think this is the answer, Sickle cell can only be passed on from parents to children. It is not contagious and it cannot skip a generation. The likelihood of having it depends on how many SC genes one or both parents have.

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
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
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:
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.
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.

1. What must be true to have offspring with black fur?
2. What must be true to have offspring with white fur?
3. What must be true to have offspring with black eyes?
4. What must be true to have offspring with red eyes?
5. What must be true to have offspring with red eyes and white fur?
Answer: Genetics
Explanation: This may sound a little strange, but in order to have animals with certain traits, they must be born with or have in the blood line to have said traits. Even then the traits exhibited may not be hereditary. There is a 50% chance that the genetics that you want the offspring to have, may not occur. When a child is made, this means that the parents donate chromosomes from both sides to give the child some of their looks. This could mean disease, eye color, hair thickness.

What is intelligent design theory?
Answer: The theory of intelligent design holds that certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection. Through the study and analysis of a system’s components, a design theorist is able to determine whether various natural structures.
Explanation:
please help Most ovens we use at home are powered by electricity or natural gas. These ovens use fossil fuels. Describe why the
energy used by a solar oven is considered a clean source of energy.
Answer:
Explanation:
Clean energy are renewable energy. This are energy from natural sources that are renewed without extra cost. Sun, wind, water are examples of renewable natural resources that helps generate clean energy.
The energy are refer to as clean because, they do not lead to any deposit of gasses that can affect the environment leading to environmental pollution. They have little or no side effects, no combustions or release of gases that are toxic or can deplete the environment as in the case of non- renewable energy.

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%
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.

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