Answer:
without cell type u cannot classifiy organisms
Answer:
a biotic habitat and an abiotic habitat.
Explanation:
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction.
Answer:
12:3:1
Explanation:
<em>The typical F2 ratio in cases of dominant epistasis is 12:3:1.</em>
<u>The epistasis is a form of gene interaction in which an allele in one locus interacts with and modifies the effects of alleles in another locus</u>. There are different types of epistasis depending on the type of alleles that are interacting. These include:
- Dominant/simple epistasis: Here, a dominant allele on one locus suppresses the expression of both alleles on another locus irrespective of whether they are dominant or recessive. Instead of the Mendelian dihybrid F2 ratio of 9:3:3:1, what is obtained is 12:3:1. Examples of this type of gene interaction are found in seed coat color in barley, skin color in mice, etc.
- Other types of epistasis include <em>recessive epistasis (9:3:4), dominant inhibitory epistasis (13:3), duplicate recessive epistasis (9:7), duplicate dominant epistasis (15:1), and polymeric gene interaction (9:6:1).</em>
Answer:
Which organisms have the greatest amount of stored energy in the food web?
(1) The producer organisms contain the least amount of stored energy. (2) Stored energy decreases from consumer 2 to consumer 3. (3) Consumer 3 contains the greatest amount of stored energy.
Which ecosystem has the greatest amount of energy overall?
Because plants and animals die at all points in food chains, decomposers are found at all trophic levels in ecosystems. Ecologists use ecological pyramids to describe the energy flow among the trophic levels. The area at the bottom of the pyramid of energy represents the greatest amount of energy in an ecosystem.
What organism gets the least amount of energy?
It follows that the carnivores (secondary consumers) that feed on herbivores and detritivores and those that eat other carnivores (tertiary consumers) have the lowest amount of energy available to them.
