when a newly formed cell enters into interphase and begins conducting metabolic functions it's is. •G0 phase •G1phase •G2 phase •S phase
Answer:
Gap 1 (G1)
- This is the phase in which the cell undergoes normal growth and cell function synthesizing high amounts of proteins.
- The cell increases in size and volume as more cell organelles are produced.
- The cell can only move to the next phase, S after synthesizing enough ribosomes.
- As the phase is almost done, the mitochondria of the cell fuse into a network of mitochondria for effective energy production for cell processes.
- If the cell can not divide again, it enters the G0.

Malaria, a type of parasite, infects 500 million people each year by infecting the red blood cells of its host. The virus, HIV, that causes AIDS, reports 50,000 newly infected persons. Which statement best differentiates the pathogens, parasites and viruses?
options: Although both rely on other living organisms to survive, viruses are usually beneficial.
Although both rely on other living organisms to survive, parasites feed on the host organism.
Although both are living organisms, viruses break down dead plants and animals that other organisms use.
Although both are living organisms, parasites depend on the cells of living things to reproduce.
Answer:
The second statement clearly differentiates the pathogens best. Parasites feed on living host while viruses depend on the cells of other organisms to survive and reproduce as they cannot function outside a living host.
Although both rely on other living organisms to survive, parasites feed on the host organism. The correct option is B.
What are parasites?A parasite is an organism that lives on or in the host and obtains its food from or at the expense of the host.
Protozoa, helminths, and ectoparasites are the three main types of parasites that can cause disease in humans.
They frequently go unnoticed because they have few symptoms. However, these infections frequently result in serious illnesses such as seizures, blindness, heart failure, and even death.
A parasitic relationship takes place when one lifeform, the parasite, feeds on another organism, the host, causing harm and possibly death.
The parasite lives on or in the host's body. Tapeworms, fleas, as well as barnacles are examples of parasites.
Thus, the correct option is B.

Answer:
b. synthesis of many extra secreted proteins.
c. mutation of a factor critical for degradation of proteins in the lysosome
d. mutation of a factor important for protein folding in the ER
The conditions that would activate the unfolded protein response are:
Synthesis of many extra secreted proteins.Mutation of a factor critical for degradation of proteins in the lysosome.Mutation of a factor important for protein folding in the ER. What do you mean by unfolded protein response?The unfolded protein response may be defined as a cellular stress response related to the endoplasmic reticulum stress. It is a mechanism through which the accumulation of misfolded protein is induced.
Unfolded protein response gats are activated when there is any mutation or alteration that takes place in the ER, and sometimes lysosomes. Because these are both organelles that mediate the protein trafficking throughout the cell.
Therefore, the conditions that would activate the unfolded protein response are statements (b), (c), and (d).

What causes leaves to change color in the Fall?
Answer:

But in the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.
A genetic experiment with peas resulted in one sample of offspring that consisted of green peas and yellow peas.444167a. Construct a %confidence interval to estimate of the percentage of yellow peas.90b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas isnot 25%, do the results contradict expectations
Answer: a.) 0.2438 < p < 0.3028
b.) No
Explanation: Confidence Interval to estimate the percentage of yellow peas is calculated following these steps:
1) Total of the offspring in one sample:
n = 444 + 167
n = 611
2) Proportion of yellow peas, which is the number of yellow peas observed divided by the total of offspring:
p = [tex]\frac{167}{611}[/tex] = 0.2733
3) For a 90% confidence interval:
α = 1 - 0.90
[tex]z_{\alpha/2}=z_{0.05}[/tex]
Checking z-table, z-score will be: z = 1.645.
4) Calculate margin of error:
[tex]E=z.\sqrt{\frac{p(1-p)}{n} }[/tex]
[tex]E=1.645.\sqrt{\frac{0.27(1-0.27)}{611} }[/tex]
E = 0.0295
5) Confidence interval has boundaries:
p - E = 0.2733 - 0.0295 = 0.2438
p + E = 0.2733 + 0.0295 = 0.3028
Then, we are 90% confident that the percentage of yellow peas is between 24.38% and 30.28%.
b.) Since 25% is in the confidence interval, and we are 90% sure the true percentage of yellow peas are inside the interval, the result does not contradict the expectations.
