The exchange of carbon dioxide and oxygen in the alveoli of the lungs is an example of what?

2 answers:

4 0

Answer:The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

Answer:

Gas exchange

Explanation:

Gas exchange can be described as the movement of gases in opposing direction across an interface. In humans and other animals with lungs, gas exchange occur as a process of respiration.

Oxygen is inhaled into the lung. In the alveoli of the lung, the inhaled oxygen diffuses into the bloodstream within the blood capillaries. Carbon dioxide in the blood travelling within the blood capillaries diffuses the other way (into the alveoli)

In superheroes, the ability to Fly (F) is dominant over not being able to fly (f). Superman can fly (Ff) (he has one dominant an

IRISSAK [1]

Answer:

Probability that the descendents are able to fly: 3/4

Probability that the descendents are not able to fly: 1/4

Explanation:

The question is incomplete.

We can build a Punnett square to find the offspring and then determine the probability that the descendents inherit the ability to fly.

Superman's genotype: Ff

Storm's genotype: Ff

Write the columns and rows titles:

F f ← Superman's genes

↑

Storm's genes

Fill in the cells with the possible combinations:

F f

F FF Ff

f Ff ff

Homozygous FF: 1 can fly

Heterozygous Ff: 2 can fly

Homozygous ff: 1 cannot fly

Total: 4

Probabilities:

Homozygous FF: 1/4 can fly

Heterozygous Ff: 2/4 can fly

Homozygous ff: 1/4 cannot fly

Able to fly: 1/4 + 2/4 = 3/4

Not able to fly: 1/4

Since the ability to fly (F) is dominant, the heterozygous Ff descendents are able to fly. That is 3/4.

Only the homozygous ff are not able to fly. That is 1/4.

What is the overall equation for photosynthesis? ( Include the 6's)

statuscvo [17]

Answer:

6CO2 + 6H2O → C6H12O6 + 6O2

Explanation:

The balanced equation for photosynthesis is: 6CO2 + 6H2O + sunlight energy = C6H12O6 + 6O2 Photosynthesis can be represented using a chemical equation: Carbon dioxide + water + light energy gives a carbohydrate + oxygen. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

Why is it necessary to have a membrane around the cytoplasm

irakobra [83]

Answer:

In plants, the cell wall is full of small holes called plasmodesmata. If there were no cellular membrane all of the fluid in the cell (cytoplasm) would just leak out. The membrane also acts as a barrier to the outside world, controlling the influx of nutrients, hormones, chemicals and other substances the cell uses.

In animals, if there is no cell wall so the absence of a cellular membrane would make all animals a pile of goop on the ground.

Explanation: in other words its important because it protects it from harmful things
