Each one of the boxes on the Punnett square represents what probability of a offspring genotype?
A-10%
B-0%
C-1%
D-25%
Answers
Answer: D - 25%
Explanation:
There are four boxes in this punnet square, each one an equally possible genotype for the offspring.
Each box then has a 1/4 (25%) possibility of being the offspring's genotype.
Each one of the boxes on the Punnett square represents a 25% probability of an offspring genotype. Therefore, option D is correct.
What are a punnet square and its uses?Every possible outcome of a genetic cross between two individuals with known genotypes is listed in the Punnett square, a table. In its simplest form, the Punnett square is a square divided into four quadrants.
A Punnett square can be used to determine the expected frequencies of various genotypes in the children of two parents. A Punnett square can be used to forecast the percentages of phenotypes that will come from known genotypes in a cross' offspring.
Thus, each one of the boxes on the Punnett square represents a 25% probability of an offspring genotype. Therefore, option D is correct.

Use the model of meiosis that you made earlier in the lesson to explain how crossing over contributes to genetic diversity. How did you modify your model? How do you think crossing over affects the expression of certain traits compared to the cells where crossing over didn’t occur?
Answers
Answer:
Due to exchange of parts of chromosome.
Explanation:
Crossing over is the exchange of segments or parts of chromosome between non-sister chromatids in the meiosis cell division. Due to crossing over, new combinations of genes in the gametes are formed that are not found in both parent which leads to genetic diversity. Crossing over affects the expression of certain traits in the organism because the organism that crossing over have different features as compared to their parents so there is a big difference between organism have crossing over and no crossing over.
The fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of ________. The fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of ________. hormones plasma protein electrolytes glucose
Answers
Answer:
plasma protein.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Glomerular capsule is also referred to as Bowman's capsule and it can be defined as a cuplike sac (structure) with a double wall, which makes up the tubular part of a nephron within the kidney of mammals. It is saddled with the responsibility of first filtering blood (ultrafiltration) under pressure to generate urine in the mammalian kidney.
Plasma comprises of about 97 percent of water by volume and it typically contains mineral ions, glucose, carbon dioxide, hormones, plasma protein, etc.
Hence, the fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of plasma protein.

Exposure to chemicals.

Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations. Hope this helped. :D

Brown eyes in humans are dominant to blue eyes. A brown-eyed man, whose mother was blue-eyed, marries a brown-eyed woman whose father had blue eyes. Figure out each member’s genotype
Answers
Answer:
Man: Bb
Man’s mother: bb
Woman:Bb
Woman’s father: bb
Explanation:
Brown eyes are dominant over blue eyes, so, in order for a person to have blue eyes, they must carry both recessive alleles for blue. This means the man’s mother and the woman’s father must have the genotype bb. The man and the woman on the other hand have brown eyes, which means they got the dominant brown eye trait from their other parent and will have a heterozygous genotype Bb.

Question 6: Describe a process scientists could use to test your conclusion from Question 5 in order to determine the exact age of the fossil. *
Answers
(1) YOU CAN REJECT the hypothesis, or
(2) YOU CAN NOT REJECT the hypothesis.
This is an important point!
You can not PROVE the hypothesis with a single experiment, because there is a chance that you made an error somewhere along the way.
What you can say is that your results SUPPORT the original hypothesis.
If your original hypothesis didn't match up with the final results of your experiment, don't change the hypothesis.
Instead, try to explain what might have been wrong with your original hypothesis. What information were you missing when you made your prediction? What are the possible reasons the hypothesis and experimental results didn't match up?
Remember, a science fair experiment isn't a failure simply because does not agree with your hypothesis. No one will take points off if your prediction wasn't accurate. Many important scientific discoveries were made as a result of experiments gone wrong!
A science fair experiment is only a failure if its design is flawed. A flawed experiment is one that (1) doesn't keep its variables under control, and (2) doesn't sufficiently answer the question that you asked of it.
5) to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

In a lake with three trophic levels (non-native fish, zooplankton, algae), an algal bloom occurs when the small population of zooplankton declines due to the predation of the invasive fish. Which of the following describes why zooplankton are the keystone species in this scenario?
Zooplankton are the smallest of all the herbivorous marine mammals in their communities.
The small population of zooplankton have an unequal effect on the marine community.
Marine mammals depend upon the work of zooplankton to convert sunlight into food.
Zooplankton help other populations survive by keeping out other herbivores.
Answers
Answers:
Zooplankton help other populations survive by keeping out other herbivores
Explanation:
This is because a keystone species are species that have large effect on the the habitat and through its effect they help to keep the ecosystem in existence. They make sure that the ecosystem exist. They help populations survive by keeping out herbivores and feeding on the algae. They help drive nutrients cycle and transfer energy from algae to invasive fish.
A park guide tells her that hoodoos like this one have been forming on Earth throughout history. Which principle explains the process that forms these rocks? A. erosion B. deposition C. weathering D. uniformitarianism
Answers
The principle that explains the process of forming hoodoos like this one is erosion. Therefore, option (A) is correct.
What is hoodoo?
A hoodoo is a tall and thin rock formation characterized by a column of sedimentary rock that has been eroded over time, leaving a pinnacle or spire-like structure. Hoodoos are typically found in arid or semiarid areas with a high concentration of soft rock such as sandstone, limestone, or volcanic tuff. These formations are often created by a combination of factors such as water erosion, wind erosion, and frost weathering.
Hoodoos can take on various shapes and sizes and may be found singly or in groups, forming intricate and awe-inspiring landscapes. They are commonly found in national parks and other natural areas around the world, including the United States, Canada, China, and Australia, where they attract tourists and geology enthusiasts alike.
