Answer:
C. Genetic material composed of nucleic acid
Explanation:
The information needed by every organism to perform life functions like reproduction, growth etc are held in the genetic material that the organism carries in its genome. Every genetic material of organisms is composed of nucleic acids, which are only two in nature i.e. Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA). This is a common feature of all organisms including bacteria and viruses that they contain genetic material which must be in form of a nucleic acid.
The viruses do not undergo a cell division, neither do they contain protein synthesis structures called Ribosomes because they do not have the ability to reproduce or perform any living process outside a living host cell. This means that they strictly depend on another organism's transcriptional, translational, replicational ability to survive.
Answer:
aluminum: bauxite and corundum
Copper: chalcopyrite
Tin: Cassiterite
Explanation:
I would expect to see HIGHER MALE INVESTMENT.
Bateman Triver hypothesis of sexual selection states that males compete with one other and female are choosy in which male to mate with when it comes to sexual reproduction.
Answer:
The correct option is D. A reasonable explanation for the change in levels of protein is that the mutation occurs in the promoter of the gene, within several hundred base pairs of the start of transcription.
Explanation:
In genetics, a promoter can be described as a region where the RNA polymerase binds initially and starts transcription. The promoter is usually present near to the gene that has to be transcribed. The rate of transcription is controlled by the promoter region too. Hence, the correct option is D. The promoter region for the eye colour was changed due to mutation.
Other options are false because a change in a codon or base pair would have changed proteins being formed and would not have slowed the process.
The advantage of asexual reproduction (binary fission) in paramecium is a large number of offspring that are reproduced very fast. Large number colonies which are formed that way may survive and compete with other organisms. Another advantage is that this type of reproduction doesn’t acquire energy for finding a mate.
