The primary function of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs. Hemoglobin (Hgb) is an important protein in the redblood cells that carries oxygen from the lungs to all parts of our body.

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown answer

larisa86 [58]

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.

Given;
x + y + z = 140 meters

According to the proportion theorem,

$\frac{x}{40} = \frac{y}{30}$

Solving for x, using cross multiplication:

$\frac{x}{1} = \frac{40y}{30}$

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40
z = 7x/8

Now, the third proportions,
y/30 = z/35

Solving for y,

y = 30z/35
y = 6z/7

x + y + z = 140

4y/3 + 6z/7 + 7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substitutoing z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520
Now,
Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,
We know that
y = 3x/4
so,
y = 40

And,
z = 7x/8
Z = 46.66

Answer:

Masks and Vaccines (RNA vaccines but normal vaccines help as well)

Explanation:

Masks: As we can tell cities that have a mask mandate have lower corona numbers

Vaccines: Vaccines give your body the antibodies that it needs to protect your body from infection without the virus. RNA vaccines are better than the normal vaccines because they are going to be produced faster than normal vaccines

I WILL GIVE BRAINLIEST IF IT'S CORRECT

iren2701 [21]

Answer: ATP releases energy when it converts to ADP .

Explanation:

During energy needs, the body cells directs the loss of a phosphate group (Pi) from ATP (Adenosine triphosphate) to yeild ADP (adenosine Diphosphate), and a further loss will yield AMP (adenosine monophosphate). For each loss energy is also released when a phosphate is removed

The reaction involves the addition of water, so it is a hydrolytic reaction, and is catalyzed by enzymes of the mitochondria, and is represented as the equation below:

ATP + H2O → ADP + Pi + free energy

Producers or Primary Consumers are the beginning link in a food chain while Decomposers or Tertiary Consumers are at the end of

patriot [66]

Answer: The given statement is True.

Food chain can be described as the sequence of transfer of energy and matter among different organisms present within an ecosystem.

It starts with producers ( occupying the first trophic level), which are consumed by consumers in a successive manner ( primary consumer→ secondary consumers→ tertiary consumer or decomposers).

Therefore, producers are beginning link in a food chain whereas decomposers occupy the last level in a food chain.
