Answer:
Microtubules have shapes like a spindle and are arranged to form centrosome and a cluster of such microtubules form centriole.
Explanation:
Microtubules are seen in eukaryotic cells to give shape and structure to the cells and they form part of the cytoskeleton. They are known to grow long and are dynamic. Centrosomes are known to be main microtubule that are found in animal cells. They are organelles that are made from the arrangement of clusters of microtubules. The centrioles are organized microtubules that actually help to serve as skeletal system of the cell. These centrioles help to determine the locations of the nucleus.
Data shows results of an experiment which was added to each peptide to culture the TRAP. Mutants of S. aureus and culture of the Agr. mutant of s. aureus.
Peptide 1 and three blocks Agr pathway
Peptide 2 blocks TRAP pathway
This is because the mutants are already blocked for one of the pathways.
Therefore it gives way to determine which pathway each peptide act on.
Answer:
Chromosome 11 likely contains 1,300 to 1,400 genes that provide instructions for making proteins
Answer:
Genetic diversity is important because it allows organisms to adapt to changes around it, thereby preventing extinction- <u><em>True</em></u>
Explanation:
Genetic diversity is one of the main reasons that brings about the survival of an organism in an ecosystem. As alleles of a gene assort independently during gamete formation, this phenomenon brings about genetic diversity. The genetic diversity allows organisms with better traits to survive and hence, they become better adapted to live in a habitat. As the organisms with better traits survive, extinction of species becomes lesser through this phenomenon.
