Answer:

A macromolecule is a very large molecule, such as protein, commonly composed of the polymerization of smaller subunits called monomers. They are typically composed of thousands of atoms or more. A substance that is composed of monomers is called a polymer .

Classify the following as A = genotype B = phenotype Use the letter A for genotype and the letter B for phenotype

Andrej [43]

The options aren’t there but here’s a few facts.
Genotypes are the alleles present in order to form a phenotype. A phenotype is the traits present based on the genotype or genetic code. For example, if you have two dominant alleles (which is a genotype)... let’s say C (as in the dominant allele stands for curly hair) Then if the genotype was CC or Cc the phenotype would be curly hair. If the genotype was cc than the phenotype would be straight hair.

Answer:

According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.

Explanation:

Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the separation of the two daughter cells, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.

In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.

Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.

In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.

The other options are not correct because:

Cell growth occurs in G1 phase.
Cell preparation occurs in interphase.
DNA replication occurs in S phase.
Mitosis is represented in yellow, and involves 4 phases.
