A graph showing the energy of the reactants and products of cellular respiration is shown here. Which description accurately compares the products and reactants of cellular respiration in terms of energy level?

Answers

Answer:

Water and carbon dioxide are products and have a lower energy level than the reactants.

In cellular respiration, water and carbon dioxide are products. According to the graph, the products have a lower energy level than their reactant counterparts.

The minimum energy is required by the element to reach the Threshold is called activation energy.

The description in the question is not given, Hence the question is incomplete.

According to the diagrams, the reactant is converted into the products when the Gibbs free energy is less than zero.

The products are modified form the reactants and the possible product in this reaction is might be water and carbon dioxide.

Answers

Answer:

I think is this

Explanation:

Which statement below applies to the evolutionary thoughts of Lamarck ONLY?
Organisms evolve over time
There are variations in populations which causes those that are best adapted to
live and reproduce successfully.
The most fit organisms survive to pass along beneficial these traits to their
offspring, resulting in more individuals each generation having the desired trait
Organisms acquire traits they need and then pass down these acquired
characteristics that they had obtained in their lifetime to their offspring.

Answer:

The most fit organisms survive to pass along beneficial these traits to their

offspring, resulting in more individuals each generation having the desired trait

Explanation:

True or false. Can you provide any evidence?
1. When species come into contact with closely related species, they interbreed and become one species again
2. Medium ground finches with relatively large beaks tend to have offspring with relatively large beaks
3.Birds with a beak type poorly shaped for the current environment are able to adapt by changing their beak types
4. Speciation, or the evolution of new species, in Galapagos finches results because natural selection favors different beak types on different islands.

Answers

False When species come into contact with closely related species, they interbreed and become one species again.

What process lead to the speciation of the Galapagos finches on the different islands?

All of them grew  from one progenitor species, which inhabitated the islands only a few million years ago.

This process, whereby species develop rapidly to use empty ecospace, is called as adaptive radiation.

Thus, its false, When species come into contact with closely related species, they interbreed and become one species again since its an example of evolution.

How does your model show what happened to the circled rock material as a result of plate motion?

Answers

Answer:

Once exposed, they are weathered, both physically (by mechanical breaking of the rock) and chemically (by weathering of the minerals), and the weathering products — mostly small rock and mineral fragments — are eroded, transported, and then deposited as sediments. Therefore, the model should show signs of deterioration and subduction.

The amino acids which are encoded by the following codons are UUC- Phenylalanine, UCU- Serine, and CUU- leucine amino acid.

What are codons?

A codon is a DNA or RNA sequence which is made up of three nucleotides that forms a unit of the genomic information that encodes for a particular amino acid or signaling the termination of protein synthesis i.e., stop signals in a cell. There are about 64 different codons of which 61 specify amino acids and 3 are used as stop codons that terminate translation process. The 61 codons codes for 20 amino acids in the human beings.

The codons given in this case encodes for different amino acids which are UUC encodes for phenylalanine, UCU encodes for serine amino acid, and CUU encodes for leucine amino acid.
