Answer:
The correct answer is - it obtains electrons from the oxygen atom in a water molecule, so it must have a stronger attraction for electrons than oxygen has
Explanation:
P680 known as which contains a reaction center in photosystem two, it is a very strong oxidizing agent that catalyzes the transfer of electrons from H2O to a bound quinone, with the production of O2.
To have a stronger attraction for electrons than oxygen has, P680 gets electrons from the O2 atom in a water molecule.
Researchers test a group of cells for DNA content immediately following mitosis and find the average to be 12 picograms of DNA per nucleus. Based on this information, how many pictograms of DNA would they expect to find at the end of the S phase and at the end of the G2 phase
Answer:
The correct answer is - 24, 24
Explanation:
In any type of cell division, there is an interphase stage before the actual process of division which is a preparatory process or stage that includes different substages like G1, S, and G2. S phase is a synthesis of the cell cycle responsible for duplication or replication of the DNA.
So, at the end of the S phase, the DNA amount becomes double its initial amount and remains the same in the G2 phase. So, if the initial amount is 12 picogram then it will be double in the S phase and remain 12 in G2 as well.

Which portion of a protein's structure has the strongest bonds? In other words hardest to break: Primary, Secondary, Tertiary, or Quaternary?
Answer:
Tertiary structure
Explanation:
The portion of the protein's structure has the strongest bonds should be considered as the teritary.
What is protein structure?Protein tertiary structure refer to the three-dimensional protein shape. The tertiary structure consist of the single polypeptide chain i.e. backbone that contains the one or more protein secondary structure where the protein domains.
Also, the amino acid side chain should intereacted and the bond should be in the no of ways.
Therefore, The portion of the protein's structure has the strongest bonds should be considered as the teritary.

Do you think it is possible to exploit the biological process of protein synthesis to make human proteins in the lab
Answer:
Yes.
Explanation:
Yes, it is possible to exploit the biological process of protein synthesis to make human proteins in the lab by the use of genetic engineering technique. DNA is the code or instructions that the cells use to make proteins so if a human protein is combined with a specific bacteria, so the bacteria is able to produce protein instructed by the DNA of the cell.
It is possible to exploit biological processes of protein as a result of proteins
having unique nucleotide sequences in its DNA.
Proteins are organic compounds which help in the building of cells and
replacement of worn out tissues. Proteins comprises of amino acids which
have unique nucleotide sequence which codes for their different types.
Protein can be made in the lab through the use of organisms in carrying out
the process. The protein DNA with unique nucleotide sequence is
engineered into the cells to produce protein.

mong the microbes responsible for producing fermented foods, the two most prominent groups are the lactic acid-producing bacteria and yeasts that produce _________. g
Answer:
Alcohol and carbon dioxide
Explanation:
Fermentation is a process carried out mostly by two organisms namely: bacteria and yeast. The bacteria converts sugar molecules to lactic acid, hence, it is called LACTIC ACID FERMENTATION. However, on the other hand, the YEAST converts sugar molecules to ALCOHOL (ETHANOL) and CO2.
Yeast is an organism capable of undergoing both aerobic and anaerobic (fermentation) respiration depending on the availability of oxygen. This fermentation process enables it produce fermented foods e.g beer, yoghurt by producing ALCOHOL as a product.

The exchange of substances between the blood vessels and the surrounding tissues can only happen in the ___________.
Answer:
The exchange of substances between the blood vessels and the surrounding tissues can only happen in the capillaries.
Explanation:
Capillaries are the exchange vessels of our body. They form a network-like structure, called the capillary area. When blood, from the larger arterioles, spreads through the many capillaries in the capillary area, the blood pressure drops and the blood flows only at a slow speed. Through the thin, semi-permeable walls of the capillaries, the exchange of gas and substances between the blood and the surrounding tissue then takes place. Subsequently, blood continues to flow through the postcapillary venules, to which the capillary area has been reconnected. Blood pressure and blood flow increase and blood eventually reaches the heart through enlarged veins.

* Infrared radiation is blocked and heats Earth.
1 Earth radiates infrared radiation.
Answer:
Earth radiates infrared radiation.
Incident infrared radiation is blocked.
Infrared radiation is blocked and heats Earth.
Visible and ultraviolet radiation heat Earth.
Explanation:
When the sunlight enters earth's atmosphere, it has short wavelength but after hitting the earth surface, it has long wavelength which allow very less solar radiation by the clouds and greenhouse gases to go into the atmosphere and as a result the earth heat up. if the greenhouse gases are increased in the atmosphere so more heat is blocked by these greenhouse gases and as a result global warming occur.

Suppose a plant on a farm needs a gallon of water per day to thrive. The farmer sets up an irrigation system that delivers exactly a gallon of water to the plant each day. However, the plant dries out. Why could this have happened
Answer:
Explanation:
This could have happened due to two reasons, either excess heat or lack thereof. The plant needs a gallon of water to thrive on a regular day. If the plant receives an excessive amount of heat it will completely evaporate the water and slowly dry out the plant until it withers away. The same can happen if there is not enough heat/sunlight, but instead, in this scenario, the water will take longer to evaporate and will accumulate in the soil. Adding more water will eventually block oxygen from passing and cause the plant to dry out and wither away.
