c. X: commensalism
Y: Parasitism
Z: Mutualism
Explanation:
X: commensalism
Rationale: in this type of relationship, only one organism benefits while the other does not benefit and is also not harmed in anyway. Whale doesn't benefits and it's not harmed by the Barnacles that benefits from the association.
Y: Parasitism
Rationale: in parasitism, one organism suffers while the other benefits in the relationship.
The fleas on warm-blooded animals is the organism that benefits solely from the association while the animals suffer.
Z: Mutualism
Rationale: in this relationship, both organisms benefit from the association and do not harm each other.
The Fungal and plant roots benefit each other.
A cell from a tissue culture has 38 chromoses after mitosis and cytokinesis one daughter cell has 37 what might occurred to cause the abnormal chromosome number
Answers
Answer:
occurred an aneuploidy (monosomy)
Explanation:
Aneuploidy can be defined as a chromosomal aberration in which the chromosome number is abnormal. In an aneuploidy, the number of total chromosomes in daughter cells is not an exact multiple of a haploid set, by either gaining or losing chromosomes during mitosis. Aneuploidies are common in cancer cells and in different types of chromosome disorders. Moreover, monosomy is a type of aneuploidy in which daughter cells have a single chromosome copy instead of the two copies found in diploid cells. For example, Turner syndrome is a monosomy caused by the loss of the X chromosome.

A homeowner lives adjacent to some wetlands, which contain standing water for much of the year. During the summer months, the
mosquitoes in the area are excessive and pose a nuisance to the homeowner. The homeowner decides to spray an insecticide on
the lawn and adjacent wetlands to eradicate the mosquitoes. The homeowner notices that after the application of the insecticide,
the number of mosquitoes is significantly reduced.
The following year, the number of mosquitoes increases in frequency as the summer months arrive and the temperatures get
warmer. The homeowner once again applies the same insecticide to the yard and adjacent wetland areas. However, this time, the
homeowner does not notice a reduction in the mosquito population after applying the chemical.
Evaluate the scenario above and select ALL statement below that apply to this case study.
A)
B)
The insecticide no longer has a chemical that can kill any mosquitoes after
the first year.
The application of the insecticide caused directional selection in the
mosquito population
There were some mosquitoes with innate genetic resistance to the
insecticide before it was sprayed the first time.
C)
D)
Natural selection selects for a phenotype in a population that has an
advantage under certain environmental pressure.
E)
The application of the insecticide caused individual mosquitoes to mutate,
which made them resistance to the chemical.
Answers
Answer: B, C, and D
Explanation:
The application of the insecticide caused directional selection in the mosquito population. There were some mosquitoes with innate genetic resistance to the insecticide before it was sprayed the first time. Natural selection selects for a phenotype in a population that has an advantage under certain environmental pressure. The correct options are B, C, and D.
What is case study?A case study is defined as 'an intensive study of a person, a group of people, or a unit with the goal of generalizing across several units'.
A case study has also been defined as a focused, systematic investigation of a single person, group, or community.
The insecticide application resulted in directional selection in the mosquito population. Before the insecticide was sprayed for the first time, some mosquitos developed innate genetic resistance to it.
Natural selection favors phenotypes in a population that have an advantage under certain environmental conditions.
Thus, B, C, and D are correct options.

Explanation:
Ia Ia
Ib IaIb IaIb
i Iai Iai
i represents type O blood which is always recessive
the capital I represents co-dominant traits (a or b)
Iai is type A because O is recessive and will be masked by Ia
IaIb is type AB because both capital I traits will be codominant
This cross ultimately gives a 1:1 ratio of type A to type AB
