The answer should be the respiratory system.
When we breathe, air is taken in our body and they travels to the lungs through the trachea. The lungs is the site where the oxygen from the air we just breathed is exchanged with the carbon dioxide (waste).
In the lungs, there's something call air sac, which diffuses the oxygen to the capillaries. At the same time, carbon dioxide from the capillaries diffuses back to the air sac. Then, we breathe out and the carbon dioxide and the remaining substances in the air that we don't need is breathe out.
That explains why there's more oxygen in the unbreathed air than oxygen from breathed air, and less carbon dioxide in unbreathed air than breathed air.
And after that, the capillaries transfer these oxygenated blood to the pulmonary vein, and then transfer them back to the heart.
Define
n = number of seeds planted.
k = number of seeds that successfully become plants.
The probability of making a profit is
p =50% = 0.5
Therefore the probability of not makng a profit is
q = 1 - p = 0.5
According to the binomial distribution, the probability of k successes out of n trials is
Create a table as shown below by using the graphing calculator.
n k P(k of n)
---- ----- ------------
4 2 0.375
8 4 0.273
10 5 0.246
12 6 0.226
16 8 0.196
20 10 0.176
50 25 0.0.112
100 50 0.08
A graph of this table shows that the probability of success i below 0.5 (50%) for all practical values of n (the number of seeds planted).
Answer: The farmer will lose money.
Answer:
The nuclear pore complex is a huge structure composed of about 30 different pore proteins, and its central channel has a diameter of approximately 10-40 nm, which is large enough for even very large protein complexes. For this reason, it is unnecessary to unfold the protein, which can pass through the pore in its native state.
Explanation:
- Protein transport into the endoplasmic reticulum (ER) or mitochondria requires unfolding of the protein and threading the amino acid chain through a channel or pore into the organelle.
- In contrast, protein transport into the nucleus does not require unfolding of the protein.
- This is because, nuclear pore complex is a huge structure composed of about 30 different pore proteins, and its central channel has a diameter of approximately 10-40 nm, which is large enough for even very large protein complexes. For this reason, it is unnecessary to unfold the protein, which can pass through the pore in its native state.
Poxviridae would be considered a viral family name. This family of viruses contains 83 species.
<h3>What is Poxviridae?</h3>
Poxviruae is a virus family composed of viruses containing a double-stranded DNA genome (instead of RNA viruses).
The Poxviridae family of viruses contains more than 20 different genera of viruses and 83 species.
This virus family (Poxviridae) can infect different types of hosts including humans and vertebrates in general.
