Which two organs do not have glands at all? Name it.
Answer:
A gland is an organ which produces and releases substances that perform a specific function in the body. There are two types of gland. Endocrine glands are ductless glands and release the substances that they make (hormones) directly into the bloodstream.
So technically there are no such things as organs without glands
A blue fish and a yellow fish mate and have green offspring. What type of inheritance is this an example of?
Differentiate between the three dose-response curves, and explain why these curves do not apply to individuals.
Answer:
LD-50: lethal dose 50%, dosage that causes death to 50% of the exposed population
ED-50: effective dose 50%, dosage that causes an effect in 50% of the observed subjects
TD-50: toxic dose 50%, dosage that is toxic to 50% of the observed subjects
These curves do not apply to individuals because it is hard to predict the dosage that will cause a response in an individual, and more practical to predict what percentage of a population will be affected by a certain dosage of a chemical.
Explanation:
Population density is calculated by
a. dividing the number of organisms in a region by the land area
b. multiplying the number of organisms in a region by the land area
C. dividing the land area by the number of organisms in the region
d. by subtracting the land area from the number of organisms in a region
Answer:
A). Dividing the number of organisms in a region by the land area.
Explanation:
The formula for calculating population density PLUS example:
The zygote is said to be Choose... , because it is able to develop into any kind of cell in the body. Adult stem cells are referred to as Choose... , because they can differentiate usually only into the cells of the tissues where they are found, whereas embryonic stem cells are Choose... because they can develop into any of the body’s cell types, although they cannot form the tissues surrounding the embryo.
Answer:
The correct answer is -
1. totipotent
2 multipotent
3. pluripotent
Explanation:
The cells that are able to develop or differentiate a different kind of cells in the body of the individual are known as totipotent cells and this ability is known as totipotency. An example of such cells is found in the zygote.
Multipotent on the other hand are the cells that are able to develop into a specific kind of cell of tissues these cells are present and the example of this type of cell is adult stem cells. Whereas Embryonic stem cells are Pluripotent cells that are characterized as the cells that develop into any type of cell of the body of an organism.

Answer:
eukaryotic chromosomes
Explanation:
Prokaryotic chromosomes have a single source of replication whereas numerous sources of eukaryotic chromosomes. Since eukaryotic chromosomes are much larger, many outlets are required for the whole chromosome to be repeated within a limited period of time.
A replication root is a segment of DNA in which a gene, plasmid or virus is repeated.
Color-blindness is a X-linked recessive disorder. under what circumstances will manifest in a child?
A) if the child is a male and it's mother has the recessive allele
B) if the child is a female and it's father has the recessive allele
C) If the child is a female and it's mother has the recessive allele
D) If the child is male and it's father has the recessive allele
Answer: A
Explanation: the gene can only be passed on the x gene, so if you are a male, you only have one x gene, so it dominates without the presence of another x gene
Answer:
A
Explanation:
because males are XY and females are XX, if two people have a son, he will receive a Y chromosome from his father and an X chromosome from his mother, if one of her alleles is recessive color blindness, there is a chance he could be color blind.
