For the answer to the question above, <span>I assume you are referring to DNA replication which takes place in the synthesis (S) phase of the cell cycle shortly before G2. If that doesn't happen, the cell will not proceed to G2 and eventually mitosis, thus division will not complete. </span>The new cells would have an incorrect amount of chromosomes.
Answer:
The DNA polymerase
Explanation:
In translation, the mRNA produced after transcription, tRNA that bring the brings the amino acids, ribosome; the organize involved in translation and all other factors eg initial factors...are involved in the process of translation. DNA polymerase is involved in the process of replication of the DNA.
Answer: D). Primary species have large numbers of offsprings, and climax communities contain species that have small numbers of offsprings.
An ecological succession is a process of gradual changes occurs in a biological community with respect to changes in the non-living abiotic factors (water, air and sunlight) and with respect to time until the ecosystem attains stability. Primary or pioneer species are the species which invade the previously barren and primitive landmass for their survival. These species make the environment suitable for the growth of other species. These grow and develop in the initial stages of succession. These species are simple organisms which reproduce asexually and produces large number of offsprings. Examples are lichen and moss. Lichen grows on the surface of rocks and acids released by them causes withering of rocks into soil which facilitate the growth of mosses and other plants. Climax community develops in an ecosystem after replacing many previously inhabiting species. Climax community develops in the end of the ecological succession. It contains species which are highly complex and uses sexual reproduction for the production of offsprings which are less in number as compared to those produced by pioneer species by asexual reproduction.
Answer:
Mary Mallon (September 23, 1869 – November 11, 1938), also known as Typhoid Mary, was an Irish-born cook believed to have infected 53 people with typhoid fever, three of whom died, and the first person in the United States identified as an asymptomatic carrier of the disease pathogen, Salmonella typhi.
