Answer:
9 and 16 for the first row of boxes
3 and 16 for the second row
3 and 16 for the third row
1 and 16 for the last row
Explanation:
I did it on edge
The ratio of offspring with the described traits to the total number of offspring would be 9/16, 3/16, 3/16, and 1/16 respectively.
What are dihybrid crosses?They are crosses involving two traits. when the traits are independent, the phenotypic ratio of the resulting offspring follows the ratio established by Mendel.
In this case, the two traits follow the Mendelian pattern and thus, assort independently.
Hence, the traits and their respective ratios would be:
Brown body, Red eyes - 9/16
Brown body, brown eyes - 3/16
Black body, red eyes - 3/16
Brown body, brown eyes - 1/16

Answers
Answer:
I can't definitively answer this because I don't know the experiment, but I can help.
Explanation:
The "control group" of an experiment is like a dry simulation, where there is no variables changed across all the different trials you do. This is different from a dependent variable or an independent variable. Using your newfound knowledge of what a control group is you can automatically cross off the last option.
Since I cannot see what your experiment was I can't give you which of the top 3 answers it is however. You need to look at which one has no change.
If I were to blindly guess I would say the top option seems like the most likely answer.

AZT is a drug that is commonly used to fight HIV infection. The active component of AZT is a nitrogenous base that mimics thymine. Normal nucleotides CANNOT covalently bond to the thymine mimic. HIV's reverse transcriptase enzyme will use the thymine mimic instead of using thymine, whereas our DNA polymerase will not make this mistake. What is the most likely explanation for how AZT prevents HIV replication
Answers
AZT works by selectively inhibiting HIV's reverse transcriptase, the enzyme that the virus uses to make a DNA copy of its RNA. Reverse transcription is necessary for production of HIV's double-stranded DNA, which would be subsequently integrated into the genetic material of the infected cell to produce its proteins. All reverse transcriptase inhibitors are analogues of the naturally occurring deoxynucleotides needed to synthesize the viral DNA and they compete with the natural deoxynucleotides for incorporation into the growing viral DNA chain.

1. Identify one population of organisms shown in the food web, other than rabbits or mice, that would likely be affected by the introduction of snowy owls AND explain why their population would be affected.
2. State which level, a, B, or C, contains the least total available energy. Support your answer.
Answers
Answer:
The population if snakes will decline because there will be competition between snakes and snow owls. The snow owls will eat the mice, but if there's only a small population of mice. Only a few snakes will eat, other snakes will die of starvation. There will be competition between snow owls, hawks and mountain lions, but they have other sources of food, unlike snakes.
Level C contains the least amount of energy. This is because each level gets less and less energy per meal, beacuse energy is released by each organism.

What characteristic could provide a species with a better chance of surviving a drastic environmental change?
(A) A small population size
(B) A highly diversified gene pool
(C) specialized cells within the body
(D) Many individuals with the recessive trait
Answers
Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.
A highly diversified gene pool could provide a species with a better chance of surviving a drastic environmental change. So, the correct option is B.
What is Diversified Gene pool?Greater genetic diversity within a population is made possible by a diverse gene pool, which raises the possibility that at least some members of the population will exhibit features that are more adapted to the new environment.
This variety can develop as a result of gene flow from other populations or mutations. The number of people having the recessive trait or a limited population size, however, would not always give an advantage in enduring environmental change. A species may have a better chance of surviving a severe environmental shift if its gene pool is extremely varied.
Therefore, the correct option is B.

Malaria, a type of parasite, infects 500 million people each year by infecting the red blood cells of its host. The virus, HIV, that causes AIDS, reports 50,000 newly infected persons. Which statement best differentiates the pathogens, parasites and viruses?
options: Although both rely on other living organisms to survive, viruses are usually beneficial.
Although both rely on other living organisms to survive, parasites feed on the host organism.
Although both are living organisms, viruses break down dead plants and animals that other organisms use.
Although both are living organisms, parasites depend on the cells of living things to reproduce.
Answers
Answer:
The second statement clearly differentiates the pathogens best. Parasites feed on living host while viruses depend on the cells of other organisms to survive and reproduce as they cannot function outside a living host.
Although both rely on other living organisms to survive, parasites feed on the host organism. The correct option is B.
What are parasites?A parasite is an organism that lives on or in the host and obtains its food from or at the expense of the host.
Protozoa, helminths, and ectoparasites are the three main types of parasites that can cause disease in humans.
They frequently go unnoticed because they have few symptoms. However, these infections frequently result in serious illnesses such as seizures, blindness, heart failure, and even death.
A parasitic relationship takes place when one lifeform, the parasite, feeds on another organism, the host, causing harm and possibly death.
The parasite lives on or in the host's body. Tapeworms, fleas, as well as barnacles are examples of parasites.
Thus, the correct option is B.
