Its definitely not A, nor is it D because food webs and food chains can be either land or aquatic animals. i think its B because a food chain goes up and a food web includes more organisms

The concentration of N2 in blood at 37 °C (body temperature) and atmospheric pressure (partial pressure of N2 = 0.80 atm) is 0.0

devlian [24]

Answer:

volume = 0.285 L

Explanation:

Henry constant is given as

$Henry constant = \frac{C}{P}$

Where C is concentration

P is atmospheric pressure

$Henry\ constant = \frac{0.00056}{0.80} = 0.0007 M/atm$

when atmospheric pressure 4 atm

$solubility = K_H\times P$

$= 0.0007 \times 4 = 0.0028 M$

In 5 litere blood , moles of N_2 $= Molarity \times volume$

$= 0.0028 \times 5 = 0.014$

At surface moles $= 0.0056 \times 5 = 0.0028$

Moles of N_2 release = 0.014 - 0.0028 = 0.0112

Mass of $N_2 = 0.0112 \times 28 = 0.314 g$

T = 37 + 273 = 310 K

$VOLUME = \frac{nRT}{P}$

$= \frac{0.0112\times 0.0821\times 310}{1}$

volume = 0.285 L

In 1973, Stanley Cohen and Herbert Boyer inserted a gene from an African clawed frog into a bacterium. The bacterium then began

BaLLatris [955]

It is known as a transgenic organism. This procedure is otherwise called "genetic engineering." Genes of one species can be altered, or qualities can be transplanted starting with one animal types then onto the next. Genetic engineering is made conceivable by recombinant DNA innovation. Living beings that have modified genomes are known as transgenic.

Chromosomes that have the same gene at the same location

Nesterboy [21]

Answer:

The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations. However, they don't necessarily have the same versions of genes.

Hope this helped, can i get a brainlest please? :)
