Answer:
Two species (B & C) are more closely related to one another than either one is to a third species (A) if, and only if, they share a more recent common ancestor with one another (at Time 2) than they do with the third species (at Time 1).
Explanation:
B and C species are closely related in this phylogenetic tree. A diagram that shows the evolutionary relationships between different species or groups of animals is called a phylogenetic tree.
By showing the branching points where species diverged from a common ancestor, it exemplifies the shared ancestry and evolutionary history of species. The arrangement of species on branches that have a recent common ancestor reflects the degree of relatedness between organisms.
Closely related species tend to cluster together on such branches. Phylogenetic trees are constructed based on similarities and differences in genetic structure, physical characteristics, or other traits observed in different animals. They are important tools in the discipline of evolutionary biology to study patterns of variation and the development of life on Earth.

What happens to carbon in plants when the plants die?(1 point)
The carbon is not released; it is lost.
The carbon will be released into the soil for use by the next generation.
The carbon is released into the air.
The carbon is released into the soil, but it is not used again.
Answers
Answer:
The carbon will be released into the soil for use by the next generation.
Explanation:
I finished the quiz and this was the correct answer.
When the plants die in that case the plants will die and the carbon from the body of the plants gets displaced in the soil. This is the end cycle of the nutrients of plants.
What is the location of carbon in plants ?It is the carbon compounds with the glucose containing the 6 number of carbons and the sugars containing total in 5 numbers of carbons.
As the plants gets the soil there body gets decomposed into the soil and later on the carbon that is absorbed from the atmosphere is given back to the soil and later on they together make the energy sources of carbon in the form of fossils which can be demonstrated later on as well.
And after plants get died, they get decayed by releasing carbon to atmosphere. The difference in the amount of carbon plants get absorbed and they do release is known as the net primary productivity. It is the direct measurement of the amount of how much plant matter is from the crops to the forests or ocean phytoplankton by the Earth produces.

This type of instrument is typically used to view cellular functions and structures.
A large central vacuole accounts for almost 90% of the plant cell volume. The Cell wall of the plant is made up of cellulose. Mitochondria deliver energy that is needed by the cell in order to accomplish metabolic activities. A Chloroplast is a membrane-bound cell organelle that facilitates the process of photosynthesis.

Keystone species are species which has the significant and a large influence on community structure with the characteristics. It is often considerably with the lower abundance and the biomass in comparison to dominant species. If removed such species can cause a serious disruption in the structure with the function of a community.

Based on the information , the scientist concluded that the regarding nucleic acid is DNA (Deoxyribonucleic Acid) .The structure of DNA is attached below -:
Explanation:
PROPERTIES OF DNA -
In humans and almost all other species, DNA, or deoxyribonucleic acid, is an inherited substance. Almost every cell in the body of an individual has the same DNA. The DNA information is stored as a code consisting of four chemical bases: adenine (A), cytosine ( C), guanine ( G) and thymine ( T). In order to form units called base pairs, DNA bases pair up with each other, A with T and C with G. A sugar molecule and a phosphate molecule are both affixed to each base. Together, a nucleotide is called a base, sugar , and phosphate. Two long strands are arranged with nucleotides that form a spiral called a double helix. The double helix structure is much like a ladder, with the base pairs forming the rungs of the ladder and the molecules of sugar and phosphate forming the vertical sidepieces of the ladder.An significant DNA property is that it can duplicate itself or create copies of it. In the double helix, each strand of DNA will serve as a template for duplicating the sequence of bases. As each new cell requires to have an exact copy of the DNA present in the old cell, this is important as cells divide.Hence, the structure identified and conclude by the scientist is DNA (deoxyribonucleic acid). Thus, the structure of DNA is attached below.
