In guinea pigs, the allele for black fur (B) is dominant over the allele for brown (b) fur. A black guinea pig is crossed with a brown guinea pig, producing five F1 black guinea pigs and six F1 brown guinea pigs. a. How many copies of the black allele (B) will be present in each cell of an F1 black guinea pig at the following stages: G1, G2, metaphase of mitosis, metaphase I of meiosis, metaphase II of meiosis, and after the second cytokinesis following meiosis
Answer:
G1: One copy of the B allele per cellG2: Two copies of the B allele per cellmetaphase of mitosis: Two copies of the B allele per cellmetaphase I of meiosis: Two copies of the B allele per cellmetaphase II of meiosis: One copy of the B allele per cellsecond cytokinesis following meiosis: One copy of the B allele in only two of the four daughter cells.Explanation:

The role of the institutional animal care and use committee (IACUC) of a research institution is to provide research animals with clean and healthy conditions in the laboratory. mediate the acquisition of animals by the institution's researchers. review all proposals for animal research to be sure the procedures to be used are appropriate and humane. review animal research proposals only to ensure that the proposed experiments are scientifically valid.
Answer:
review all proposals for animal research to be sure the procedures to be used are appropriate and humane.
Explanation:
The Institutional Animal Care and Use Committee (IACUC) is a federal committee responsible for approving and/or prohibiting the use of animal (nonhuman vertebrate) subjects for research, testing and teaching purposes, as well as the inspection of animal facilities. IACUC evaluates the institution's animal programs and procedures as described by the Office of Laboratory Animal Welfare (OLAW). This committee has the task to verify animal's well-being by minimizing pain and distress (for example, by ensuring the use of non-invasive methods when possible). Researchers/educators that use animals for research/teaching purposes must previously submit a written request defined by the IACUC's guidelines.
Which best describes a recessive allele?
A. Always inherited from a parent when a dominant allele is inherited from the other parent.
B. Never inherited from a parent when a dominant allele is inherited from the other parent.
C. Only determines phenotype when a dominant allele for the same trait is present.
D. Does not determine phenotype when a dominant allele for the same trait is present.
Answer:
B!
Explanation:
A recessive allele can't be shown in the child unless there is no dominant allele.

Which pattern of inheritance does nose size follow?
complete dominance
codominance
incomplete dominance
sex-linked dominance
Answer:
incomplete dominance
Explanation:
This is because incomplete dorminance is a type of inheritance pattern in which a dorminant allele does not completely masked the effect of recessive allele. The recessive allele is expressed little and the dorminant. Example is the nose size. The allele for big nose and recessive allele for small nose are not completely dorminant.

The relationship between a carnivore and an herbivore can be stated as
A
parasite and host
B
predator and prey
C
prey and predator
D
scavenger and parasite
The relationship between a carnivore and an herbivore can be stated as B predator and prey.
What are the predator and prey ecological relationships?The predator and prey ecological relationships can be defined as ecological associations in which an organism serves as food for others in the food web, thereby leading to the homeostasis of the whole system in the food chain.
Therefore, with this data, we can see that predator and prey ecological relationships are based on different trophic levels where one organism situates below in the food chain is the prey of another.

How “Competition in an ecosystem” is playing a role in life?
What effect did the human population have on Easter Island? How did they change the island's natural cycling of matter and energy?
Answer:
The population history of the island remains highly controversial. In addition to internal conflict, the population crash has been attributed to “ecocide,” in which the Island's resources were exhausted by its inhabitants, reducing its ability to support human life.
Explanation:
Europeans was known to discovered Easter Island in 1722 and it's name was given by Captain Admiral Jacob Roggeveen.
The human population growth had a negative effect on the Easter Island.
The ecocide hypothesis is the one explanation to how the human population increased exponentially since its colonization and as such
Human populations did over increased the carrying capacity of the Island to support sustainable crops, and in consequence, the island was severely deforested.
The island's natural cycling of matter and energy also reduced or change and as such the people fought among themselves for scarce resources of the island. They had little food and were starving and they resorted to cannibalism.
The island was also plaque by blackbirding from 1862 to 1863.
