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.
You decide to create a composting bin for your house. While checking on it one day, you notice that the compost bin has started to smell like rotting eggs. You know that a successful compost bin should not smell like this. You take a sample of the pile and check for the presence of microorganisms under the microscope. You see that there are indeed microorganisms. Given this information, what should you do to resolve the smell of your compost?(1 point)
Creating a tent for the pile to shield it from the sun and heat will help resolve the smell.
Turning the pile to aerate the compost and expose it to oxygen will help resolve the smell.
Adding more “brown” materials to the pile to increase the amount of carbon will help resolve the smell.
Adding more “green” materials to the pile to increase the amount of nitrogen will help resolve the smell.
Answer:
Turning the pile to aerate the compost and expose it to oxygen will help resolve the smell
A plastic bottle contains 32.5 L of gas at a pressure of 45.7 kPa and
is compressed to a volume of 4.1 L. What would be the new
pressure?
Answer:
Final pressure, P2 = 362.26 kPa
Explanation:
Given the following data;
Initial volume = 32.5 Liters
Initial pressure = 45.7 kPa
Final volume = 4.1 Liters
To find the final pressure, we would use Boyle's law;
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
[tex] PV = K[/tex]
[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]
Substituting into the equation, we have;
[tex] 45.7 * 32.5 = P_{2} * 4.1 [/tex]
[tex] 1485.25 = 4.1P_{2} [/tex]
[tex] P_{2} = \frac {1485.25}{4.1}[/tex]
[tex] P_{2} = 362.26 [/tex]
Final pressure, P2 = 362.26 kPa
Oxygen-rich blood is carried through pulmonary arteries from the lungs to the heart?
It is false that oxygen-rich blood is carried through pulmonary arteries from the lungs to the heart.
What is pulmonary artery?The two principal arteries leaving the right ventricle of the heart are known as the pulmonary arteries. Low-oxygen blood is seen in this lower chamber of the heart. This blood travels to the lungs through the pulmonary arteries.
The middle mediastinum contains the main pulmonary artery, as well as the pulmonary arteries that follow on the right and left. They emerge from the four chambered heart's right ventricle and carry blood to the lungs.
Right side of heart sends deoxygenated blood to pulmonary artery. Nature has made it such that this blood reaches the lungs where carbon dioxide can be released and then oxygen can be loaded.
It is true that all arteries convey oxygenated blood, with the exception of the pulmonary artery.
Thus, the given statement is false.

could a panda bear survive in the dessert why or why not?
Answer:
It will not survive
Explanation:
mainly due to the fact that it is adapted to its environment and living in the desert will not be ideal since it has such a large amount of fur and there is no food source for the animal
Which tree above shows a different evolutionary history from the others? Explain your answer.[ ]
Answer:
the second one is the right answer
The second evolutionary tree (2) is showing a different evolutionary history from the other trees.
What is an evolutionary tree?An evolutionary tree is a diagram/graphic used in biology to show evolutionary relationships between taxa.
The taxa located at the tree can be different species, genera, orders, etc.An evolutionary tree is monophyletic when all descendants originated from the same ancestor.In conclusion, the second evolutionary tree is showing a different evolutionary history from the other trees.

How can I get my own karyotype?
If you guys don't know what karyotype is, it's a photo of person's full set of chromosomes. So basically my crush keeps making fun of me and said "You're so d*mb, you probably lost a chromosome" but I didn't lose any. So I want to sign up to get my own karyotype to prove I have a full set of chromosomes. Do you guys know which site I can sign up and pay to get my karyotype done? Thx
Answer: really any doctor
Explanation: karyotype tests are done typically during pregnancies, i’m sure a medical facility could do it.
plants are able to bend their stem so they are closer to a light source________
what adaption do they use?
structural
physiological
behavioral
Answer:
I think its physiological (B)
Explanation:
In phototropism a plant bends or grows directionally in response to light. Shoots usually move towards the light; roots usually move away from it.
Plants have a variety of developmental, physiological, and growth responses to light—sometimes only to particular wavelengths of light.

Avanti works in a bookstore. She has four books and is going to place them in two stacks. The diagram above shows the books before they touch. Use the information in the diagram to answer the question. How did the temperatures of the four books compare before they touched? How will the temperatures of the two top books compare after the books have been touching for a while, and why? HELP
Answer:
Well they didn't transfer any energy when they weren’t touching and it didn't produce any energy if it didn’t move. Since they are on top of each other they are causing momentum on each other creating kinetic energy

(A) It would not be able to make proteins or transfer substances to other cells
(B) Would not be able to transfer genetic information to other cells
(C) It would not be able to store energy or communicate with other cells
(D) It would not be able to store water or protect itself from viruses
Explanation:
Water moves in and out of a cell in conformity with the concentration gradient formed between the membrane of the cell and the extracellular solution. The process whereby the water moves from a region of low solute concentration to a high solute concentration via a semi-permeable membrane is called OSMOSIS.
In this case, the solute concentration of the blood cannot be regulated, hence, it rises. This causes the solute concentration of the blood to be high or is said to be hypertonic than the cell's. This creates an osmotic gradient causing water to flow out of the hypotonic (low solute concentration) cell into the hypertonic extracellular environment (blood). Once water flows out of the cell as a result of osmosis, the cell shrinks or shrivels i.e. reduce in size.
Q. Why is energy required by an organism even during sleep ?
Q. Give the energy transformation that takes place in the process of photosynthesis.
Q. What is chlorophyll ?
Q. Name the various factor which affect the rate of photosynthesis.
Q. Define photolysis.
➥ Even, when an organism is asleep, various biological processes keep on occurring in its body which requires energy.
➥ During photosynthesis‚ “Solar energy is converted into chemical energy”.
➥ “Chlorophyll” is a green coloured pigment found in plants that helps in absorbing sunlight used in photosynthesis.
➥ Several factors which affect the rate of photosynthesis:
Light. Temperature. Water.CO2.➥ “Photolysis” is the process by which water is split into oxygen, which is released into the atmosphere, and hydrogen.
