Answer:
It means the way genes are expressed is the same in most organisms.
Explanation:
All living organisms use the same DNA or RNA as their genetic material. The manner in which the information in these genes are encoded or expressed is known as the GENETIC CODE. Genetic code comprises of all the codons that specifies amino acids in all living organisms. Only 20 amino acids in different sequential pattern makes up all proteins.
Nearly all living organisms use the same genetic code, as a codon does not specify a different amino acid in another organism. It is universal in all organisms that AUG codon specifies Methionine. Only slight differences to this pattern of genetic expression has been discovered, hence, the genetic code is said to be NEARLY UNIVERSAL.
The idea of a nearly universal genetic code refers to the common genetic 'language' shared by nearly all organisms. This means that, across an extraordinarily diverse array of species, the same sequences of DNA and RNA (the genetic code) translate to the same amino acids, which, in turn, build the same proteins. The universality of this code strongly suggests that all life shares a common origin.
The nearly universal genetic code refers to the fact that virtually all living organisms use the same codons, or sequences of DNA and RNA, to code for specific amino acids, which are the building blocks of proteins. This conservation of codons is seen across a vast array of species, with minor exceptions. For instance, if the mRNA encoding the globin protein in horses is transferred to a tulip cell, the tulip would synthesize the same protein, suggesting a common origin of all life on Earth.
The 64 possible combinations of triplet codons coding for 20 amino acids and with the occurrence of only one genetic code demonstrates the idea of degeneracy in the genetic code. This means that more than one codon can specify the same amino acid. For instance, unusual amino acids such as selenocysteine and pyrrolysine have been found in archaea and bacteria, which use unique codons.
Ultimately, the universality and degeneracy of the genetic code highlight the homologous characteristic shared by all species suggesting they share a common ancestor. This is powerful evidence for the shared biochemistry in all forms of life.

B. In both oogenesis and spermatogenesis, the cells become haploid after meiosis I.
C. In both oogenesis and spermatogenesis, the cells become haploid after meiosis II.
D. During spermatogenesis, the cells become haploid after meiosis I, while in oogenesis, the cells become haploid after meiosis II.
Answer:
B. In both oogenesis and spermatogenesis, the cells become haploid after meiosis I.
Explanation:
i got it right
B. freeze
C. rinse
D. soak
Answer: D. soak
A dye is a colored substance that has the affinity for the substrate on which it is applied. A dye is typically an organic compound, which is mixed with a suitable binder, to keep it in a liquid state. It is used to provide color to the cloths.
When the dye has been applied to the shirt, all that remained was to soak it because, the binder or solvent will be absorbed by the shirt by capillary action, and the dye will impart it's color.
Which of the following is the control group in this experiment?
The control variable is a group that serves as a baseline for comparision. The independent variable is not applied or only applied at a baseline level.
The independent variable is the covering of the ice with different materials. Because group 4 wasn't covered, it is the control variable.
The control group in this experiment is group 4, which remained uncovered.
In an experiment, the control group is the group that does not receive any treatment or manipulation. It serves as a baseline for comparison to the other groups. In this case, the control group is not covered with any material, which means it is not subjected to any additional factors that could affect the melting rate of ice.
By comparing the results of the other groups (group 1 covered in plastic, group 2 covered in paper, and group 3 covered in aluminum) to the control group, the researchers can determine the effect of different materials on the melting rate of ice.
I hope this helps you. :)
Hi
The 3 level of diversity are
1) Genetic diversity
2) species diversity
3) Ecosystem diversity
I hope this answer help !
Answer: Move substances
Explanation:
The process of diffusion and active transport are some of the process inside the body which helps in transportation of the materials from one place to another.
The substances move a region of higher concentration to lower concentration in case of diffusion and with the help of energy the molecules moves from lower concentration to higher concentration.
The correct answer is option D.
