How do we represent dominant and recessive alleles?.
Answers
Answer:
Dominant alleles are represented with an uppercase letter.
Recessive alleles are represented with a lowercase letter.
Explanation: Take for example, “AA”. Both “A’s” in this allele pair are uppercase, so they are dominant alleles. As another example, let’s say an allele pair was “bb”. Since both of the “b’s” are lowercase, they each would be a recessive allele.

How can cells from the same organism have such different shapes and functions?
Answers
Answer:
As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity. B Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.
Explanation:
Answer:
Because cells are not only characterized by by their genetic material and other interior components, but also by the genes they express. Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. For example melanocytes in the skin are highly specialized cells which mostly make the pigment melanin. Plasma cells on the other are highly specialised for making antibodies.
If catfish eat algae, and there's 20,000 kcal/m2 of energy stored as biomass in algae in a pond, how much energy stored as biomass in catfish in that pond would you expect there to be?

explain how weather,climate,and seasons could affect the biotic and abiotic factors of an ecosystem
Answers
Weather, climate and seasons are factors that limit the distribution of different species of living beings in ecosystems, influencing survival and reproduction.
What are the biotic and abiotic factors of an ecosystem?Biotic factors are each of the living organisms of an ecosystem and abiotic factors are all non-living ones such as organic and inorganic substances in the system as well as environmental conditions.
Weather, climate, and seasons could affect these factors in altering the distribution of species, but would also decrease primary production, which would affect survival and growth.
Therefore, we can conclude that the weather, climate and seasons are factors that limit the distribution of different species of living beings in ecosystems, influencing survival and reproduction.
