Choose the letter that indicates the organelle that contains most of a cell's DNA. An animal cell with definite structures label

ed from A to E. The vesicles with solid particles inside are labeled A.
The vesicles with no solid matter inside are labeled B.
The large membrane-bound organelle is labeled C. It is located in the center of the cell and contains a mass of densely stained granules and fibers.
The structure labeled D consists of flattened membranous-like stacks.
The tiny dots labeled E are located everywhere in the cell and do not have any membrane.

Answer:

C.

Explanation:

A cell is composed of specific structures that perform specialized functions called ORGANELLES. Among these organelles, an important one exists called NUCLEUS, which is responsible for all other cellular functions as it directs them.

The NUCLEUS is located centrally in the cell and is found as a membrane-bounded organelle in cells that possess it (eukaryotes). The NUCLEUS, which is described in this question with the letter "C" contains most of a cell's genetic material called DNA.

Briefly describe how the experiments of Avery, McCarthy, and MacLeod, building on the work of Griffith?
satela [25.4K]
The Avery–MacLeod–McCarty experiment<span> was an experimental demonstration, reported in 1944 by </span>Oswald Avery<span>, </span>Colin MacLeod<span>, and </span>Maclyn McCarty<span>, that </span>DNA<span> is the substance that causes </span>bacterial transformation<span>, in an era when it had been widely believed that it was </span>proteins<span> that served the function of carrying genetic information (with the very word </span>protein<span> itself coined to indicate a belief that its function was </span>primary<span>).

It was the culmination of research in the 1930s and early 20th Century at the </span>Rockefeller Institute for Medical Research<span> to purify and characterize the "transforming principle" responsible for the transformation phenomenon first described in </span>Griffith's experiment<span> of 1928: killed </span>Streptococcus pneumoniae<span> of the </span>virulent<span> strain type III-S, when injected along with living but non-virulent type II-R pneumococci, resulted in a deadly infection of type III-S pneumococci.

In their paper "</span>Studies on the Chemical Nature of the Substance Inducing Transformation of Pneumococcal Types: Induction of Transformation by a Desoxyribonucleic Acid Fraction Isolated from Pneumococcus Type III<span>", published in the February 1944 issue of the </span>Journal of Experimental Medicine<span>, Avery and his colleagues suggest that DNA, rather than protein as widely believed at the time, may be the hereditary material of bacteria, and could be analogous to </span>genes<span> and/or </span>viruses<span> in higher organisms.</span>

Which reaction best explains why carbon is able to from macromolecules ?
guajiro [1.7K]

Answer:

Carbon can bond with many elements

Explanation:

Carbon can bond with many elements, including itself, to form macromolecules. Moreover, it can form four bonds, and that makes possible many different arrangements of the atoms in the molecules.

A is <em>wron</em>g. Carbon is among the seven smallest elements in the Periodic Table.

C is <em>wrong</em>. Carbon is found in living things because it can form macromolecules, not the other way around.

D is <em>wrong</em>. Carbon can bond with many other elements beside itself.
