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.
What is the sexual reproduction process of angiosperms?
Answer:fertilization
Explanation:
Answer: Sexual reproduction occurs in three stages: pollination, fertilization, and dispersal. During pollination, pollen is transferred from the anther to the stigma. Once the pollen is stuck to the stigma, it produces a pollen tube that grows down the style to the ovary and into the ovule. A sperm cell then travels down the pollen tube into the ovule and fertilizes the egg cell. The fertilized egg is called a zygote. This zygote grows into a plant embryo. The embryo is located inside the seed along with the seed coat and stored food. The ovule develops into the seed. The ovary develops into the fruit that protects the seed. The fruit also helps disperse the seed. Seeds are dispersed, or spread, to new locations, where they grow into seedlings. or pollen is taken to the stigma. i took the test
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.

Which of the following is an ethical concern associated with the use of DNA fingerprinting in forensics?
A.) Does the process lead to false convictions of individuals?
B.) How many criminal trials will use DNA fingerprinting as evidence?
C.) Will the victims of crimes approve of the use of DNA evidence in a trial?
D.) Are there enough labs to carry out the genetic testing needed for DNA fingerprinting?
Answer: A
Explanation: human error
The study of the gene is called genetics.
The correct answer to the question is option A Does the process lead to false convictions of individuals.
What is DNA fingerprinting?DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect.The DNA of any person can get very easily placed in a crime scene which could hinder the investigation and can lead to a false conviction.

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.

What is the correct sequence of events for the cell cycle ?
Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Explanation:
The cell cycle is a four-stage procedure in which the cell enlarges (gap 1, or G1), copies its DNA (synthesis, or S), gets ready to divide (gap 2, or G2), and splits (gap 4, or S) (mitosis, or M, stage).
What is the cell cycle?Interphase, which accounts for the time between cell divisions, is made up of the stages G1, S, and G2.
A cell's growth and division are accompanied by a sequence of processes known as a cell cycle.
A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.
Therefore, in eukaryotes, the cell cycle consists of four different phases: G1, S, G2, and M divide the cell.

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.
