Answer:
The capital letter is used to show a dominant trait, while a lowercase is used to represent a recessive trait.
Explanation:
If you are to take a Mother and a Father as example, and they have 3 children, the father's brown eyes as example we can show the children with capital and lower case depending on their looks. If the Father had brown eyes and 2 of his children out of 3 have brown eyes, we can represent that as a dominant trait, so it would be R. Then, if we take the father's hair color, brown, and the mothers hair color, blonde, we can say 2 of 3 children have brown hair, so 1 of 3 children have brown hair. So we now know that brown hair is a recessive trait. 2 of 3 children have blonde hair so the child with brown eyes and blonde hair could be represented like "Rr". Hope that helps, this is just my little explanation of this!
In humans, brown eyes are generally dominant over blue eyes. Find the phenotypic and genotypic ratios of a cross between two heterozygous brown-eyed people. Choose This is a required question
Answer:
Brown eyed genotype: Aa (eterofzygous) or AA (homofzygous)
The genotypes derived from the cross are: AA, Aa, Aa, aa
The phenotypes are: 3 with brown eyes and 1 with blue eyes (aa)
The phenotypic ratio is 3:1 (brown eyes: blue eyes) and the genotypic ratio is 1:2:1 (dominant homozygous: heterozygous: recessive homozygous).
What happens in a heterozygous cross?In humans, the allele for brown eyes (B) is dominant over the allele for blue eyes (b). Heterozygous individuals, who carry one copy of each allele (Bb), will have brown eyes.
When two heterozygous brown-eyed individuals (Bb) cross, the possible genotypes of their offspring are:
BB (brown eyes): 25% chance (homozygous dominant)
Bb (brown eyes): 50% chance (heterozygous)
bb (blue eyes): 25% chance (homozygous recessive)
So, the genotypic ratio of the offspring is 1:2:1 (BB:Bb:bb).
As for the phenotype, the only possible one is brown eyes and it occurs in 75% of the offspring (25% BB + 50% Bb)
Therefore, the phenotypic ratio of the offspring is 3:1 (brown eyes: blue eyes)
It's worth noting that while this is the typical outcome of crosses involving the eye color genes, it's not universally accurate, as other factors and genes might have an influence on the phenotype. Additionally, in reality, eye color is a complex trait and many other genes are involved not just B and b, so the dominance is not always that clear.

What are four conditionsrequired for fossilizationof an organism?
Answer:
The organism generally must have hard parts such as shell, bone, teeth, or wood tissue; the remains must escape destruction after death; and the remains must be buried rapidly to stop decomposition. This does make the fossil record biased because animals with soft bodies are less likely to form fossils.

how does a plant cell look under a microoscope
Plant cell under the microscope
The structure and shape of the cell are more rigid when compared to animal cells as plant cells have a rigid cell wall that provides a more solid structure to the plant cell. The shape of the plant cell is usually rectangular in shape even though some plant cells have a triangular shape.i hope it helps you:-):-)

Question 3
What is the job of the nucleus?
O lets some things in and out of the cell
O'protects the cell from intruders
stores the DNA
Answer:
The core controls and controls the exercises of the cell (e.g., development and digestion system) and carries the qualities, structures that contain the innate data.
Atomic pores, little channels that span the atomic envelope, let substances enter and exit the core. Each pore is lined by a set of proteins, called the atomic pore complex, that control what atoms can go in or out.
The core is spheroid in shape and isolated from the cytoplasm by a layer called the atomic envelope. The atomic envelope confines and ensures a cell's DNA from different atoms that seem incidentally harm its structure or meddled with its handling.

Why is exponential growth usually very rare in nature
Answer:
Explanation:
The scarcity of natural examples is due to the fact that there are population controls due to a limiting amount of resources such as food, light, shelter, water as well as to factors such as predation, climatic change, and disease.
Answer:
In the real world, with its limited resources, exponential growth cannot continue indefinitely. Exponential growth may occur in environments where there are few individuals and plentiful resources, but when the number of individuals gets large enough, resources will be depleted and the growth rate will slow down.

Which of the following is NOT a resource that organisms fight over for survival?
Reproduction

Oxygen

Answer:
Oxygen
Explanation:
Oxygen because when was the last time you saw one organism beating up another organism because that one was taking too much, its air, or air near it. Organism, however, do fight for mating rights (Reproduction), Food, Water, and Shelter because these are things that could go scarce, unlike oxygen which is always being pumped out by plants.

Predict:
Observe:
Explain:
Answer:
If green house gas emissions do not decrease the globe will increasingly get warmer. The sun's heat enters the atmosphere, some heat will escape, some will be trapped. Carbon dioxide causes the heat to remain in the atmosphere. Without carbon dioxide Earth would very cold, but with the use of fossil fuels and other unsustainable resources we are releasing too much carbon dioxide in the atmosphere. This is causes way too much heat to remain trap. And this is what is causing global warming
