Answer:

Crossing over is the process by which genetic material is exchanged by non-sister chromatids during meiosis.

Crossing over results in a new combination of genetic information for the cell for a specific trait.

Crossing over ensures that organisms are not identical from generation to generation.

Genetic recombination allows for a variation in genetic material that is passed through the generations.

Explain the significance of a member of the normal microbiota that harbours an R plasmid.

SCORPION-xisa [38]

Answer and Explanation

The normal microbiota that harbouring an R plasmid will transmit its R plasmid to the normal microbiota because the normal microbiota does not have R plasmid after transmission of R plasmid its increases the resistance capacity of normal microbiota.

Clara is a vegan and she does not drink milk, a food advertised as a best source of calcium. But she is not worried too much sin

marysya [2.9K]

Explanation:

%DV label= 27%

1 cup of cooked collared greens= aprx 266.60 mg of Calcium

Assuming Clara is...

a teen, her required adequate intake (RAI)= 1300 mg/ day
an adult, her RAI= 1000 mg/day

For teenaged Clara

∵27 % DV= 270mg

% daily Calcium= $\frac{270}{1300} * 100=$ = 20.8 ≈ 21%

=0.21

<u>21% of her daily calcium needs is in a cup of cooked collard greens.</u>

Calcium is an essential mineral required by the human body, it is involved in cell signalling, muscular function and homeostasis. Along with fats, fiber, vitamin A and C and iron, calcium makes up part of a recommended daily intake target or DV- these are integral to a balanced diet.
