Carbon could form to Carbohydrates, Lipids, Proteins and Nucleic Acids when bonded with other carbon atoms
A phylogeny is an evolutionary ”tree” of related
organisms that can be constructed by using
information obtained from the genetic material.
Genetic information is contained in all living cells,
in the form of long DNA molecules that take the
shape of connected double- stranded spirals
(DNA stands for deoxyribonucleic acid). DNA
spirals, or “helixes”, are tightly compressed in the
nucleus of every cell. Their information is
organized into a code made up of four small
molecules — the building blocks of DNA. The
molecules, called nucleotides, are labelled:
A (adenine), C (cytosine), G (guanine) and T
(thymine).
It is possible to draw conclusions about the
evolution of a group of plant or animal species,
and the relationships among them, by comparing
selected pieces of DNA.
True I think but not sure
The answer is A. Animals.
First of all humans and insects belong to the group of animals. There are about 1.6 million known species of animals which include many more groups. At least 1 million of animal species are insects. Humans belong to the one only species Homo sapiens of Hominina clade. Talking <span>about </span>plants, there are about 300.000 species, leaving animals as the right answer.
Answer:
True
Explanation:
A DNA molecule is composed of the nitrogenous bases stacked inside the two backbones made up of the phosphate and sugar molecules. The nitrogenous bases form the nucleotide which when read in the triplets called codons code for specific amino acid and then form proteins.
If we say that we have to protect the DNA than it means that we have to conserve the DNA molecule. Conserving the DNA molecule means that the sequence of nucleotide which codes for specific proteins must be conserved as it is the protein molecule that is essential for survival.
Thus, true is correct.
