Is it possible for energy to be transferred directly from the first trophic level to the third trophic level? Explain.

1 answer:

7 0

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

What causes ocean tides to reach higher up on a shore at certain times of day than at others? A. The moon's gravity and Earth's

Dima020 [189]

Answer:

Explanation:

I read about ocean tides. the Moon has an effect on the ocean which causes the ocean to bulge toward the Moon. When the Moon is in alignment with the sun the ocean bulges out more because of the added gravity. The Moon though smaller than the sun has more gravitational pull than the sun.

Eukaryotic cells. Classify each statement according to whether it occurs in eukaryotic cells, prokaryotic cells, or both.

frutty [35]

Answer:

Both:

The start codon is often AUG

Eukaryotic cell only:

The larger subunit of the ribosome is 60s.
The ribosomes initially binds the 5' end of mRNA.

Prokaryotic cell only:

The ribosome is 70s
Translation occurs in the cytoplasm
There are multiple ribosome binding site

Explanation:

AUG is the common start codon for both eukaryotic as well prokaryotic cells. In eukaryotic cell, it codes for methionine . While in prokaryotic cell, it codes for formyl methionine.
In prokaryotic cell, ribosomes are found in cytoplasm, hence the translation occurs in cytoplasm.
Eukaryotic ribosome consists of two subunits; 40s and 60s(larger subunit)
Prokaryotic ribosomes have 70s ribososme, which consists of 50s and 20s subuints
in eukaryotic cell, 40s ribosome initially binds to the cap at the 5' end of mRNA.
Bacterial mRNA contain multiple ribosome binding sites.

A class of lipids used as chemical messengers, to signal cells to undergo changes, is called triglycerides. phospholipids. polys

max2010maxim [7]

A class of lipids used as chemical messengers, to signal cells to undergo changes, is called Monoglycerides. Its a class of glycerides which are composed of molecules of glycerol linked to fatty acid by easter bond.

Monoglycerides are the type of glyceride and that made up of glycerol and one fatty acid chain. Triglycerides are very similar expect they have three fatty acid chains. Mono and diglycerides may be manufactured through the reaction of plant or animal derived fatty acids with glycerol which breakdown plant or animals which derived fats and oils.

Lipids such as steroid hormones that serve as chemical messengers between cells , tissues and organs and other communicate signals between biochemical system within a single cell.
