The rda for protein increases by an additional ______ grams per day during pregnancy.

Artemon [7]

The RDA for protein increases by an additional 25 grams per day during pregnancy. Protein RDAs are calculated using 0.8 grams of protein per kilogram of body weight, which means an adult weighing 68 kilograms needs at least 54 grams of proteins each day . The RDA for pregnant and nursing women is a bit higher because of the protein needed for the growth of fetus, it is about 71 grams of protein per day.

las ondas transversales producidas en una cuerda de guitarra tienen una rapidez de propagación de 150 m/s y su longitud de onda

Alex Ar [27]

Answer:

Period of the waves = 0.00013 s (Approx.)

Explanation:

Given:

Propagation speed = 150 m / s

Wavelength = 0.02 m

Find:

Period of the waves

Computation:

Period of the waves = Wavelength / Propagation speed

Period of the waves = 0.02 / 150

Period of the waves = 0.00013 s (Approx.)

In a cross between individuals of a species of tropical fish, all of the male offspring have long tail fins, and none of the fem

Sergio039 [100]

In this cross the trait of long tail fins is associated with the “Y” chromosome of the male.

Thus the alleles of the male are represented by XY” where X chromosome has no trait of long tails find

And the allels of the female are represented by XX, as they do not have long tail fins.

When these two are crossed , the following punnet square is produced

X Y”

X X X X Y”

The XX is the female while the XY” is the male offspring.

Is mitosis involved with two sets of nuclear divisions

Naya [18.7K]

Answer:

NO. Mitosis involves one set of nuclear division and results in two nuclei that are exactly the same as the original. On the other hand, meiosis involves two sets of nuclear divisions.

Explanation:

Mitosis is a type of cell division normally occurring at the sites of growth and development of new tissues and also at sites of repair. It also occurs during asexual reproduction of organisms. Each mitotic cell division is a process that follows distinct phases.

Each mitotic division results in the formation of two daughter cells which are genetically identical to the parent cell, that is they have the same number and type of chromosomes as the parent cell.

During telophase, a nucleolus develops in the nucleus of each daughter cell. The cytoplasm divides in the process called cytokinesis. An invagination develops and finally splits the cell into two daughter cell each with its own nucleus and cytoplasm.
