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.

Explain how covalent bonds and hydrogen bonds hold together a strand of DNA
Answer:
Covalent bonds appear inside every linear chain and connect bases, sugars, and phosphate groups.
Hydrogen bonds appear between two strands and involve the base from one strand with the base from another strand in the complementary pairing.
Explanation:
A covalent bond is a chemical bond formed by joining electrons of two non-metal atoms into one or more common pairs.
A hydrogen bond (X-bond) is a type of weak chemical bond based on electrostatic attraction between a hydrogen atom and a nucleophilic atom that contains free electron pairs.

Hemophilia is a recessive, X-linked disorder. If a male child is born with hemophilia and neither the mother nor the father has hemophilia, which of the following statements is most likely true?
1. the father is the carrier
2. the child’s sister will have hemophilia
3. all answers are correct
4. the mother is the carrier
Answer:
I may be wrong but maybe 2
Explanation:
Answer:
4
Explanation:
Because the mom may have a recessive x when she was born so she carries it. Males can't be carriers.
Studies of conjugation in multiple Hfr strains revealed that the bacterial chromosome was: circular. single stranded. directional. None of the above
Answer:
circular
Explanation:
Studies of conjugation in multiple Hfr strains revealed that the bacterial chromosome was circular.
Conjugation in bacteria is a process through which genetic materials are directly transferred from one bacterium to another. The process was first discovered by the experimental work of Joshua Lederberg and Edward Tatum in 1946. The donor bacterium first makes a copy of the genetic material by replication and then pass a copy to the recipient bacterium.
It was during the process of conjugation that scientists discovered that the genetic material of the bacteria is a circular chromosome, also known as the F plasmid. The circular chromosome breaks at a particular point and becomes a linear structure before replication and then folds back thereafter. The replicated chromosome is linearly transferred to the recipient cell.
How many base pairs per turn of the helix would most likely correspond to a positively supercoiled DNA molecule
Answer: Five
Explanation:
A positively supercoiled DNA is a overwound DNA. It forms a twisted shaped of figure eight. The lobes of the figure will appear rotated in clockwise or anticlockwise direction with respect to each other. The base pair per turn for the helix in positively supercoiled DNA molecule is five. This conformation of DNA inhibits the replication and transcription processes due to overwound nature of DNA.

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.

Incident infrared radiation is blocked.
1 Visible and ultraviolet radiation heat Earth,
* 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.

What are three types of forceful lifting of air?
Answer:
The correct answer is - orographic lifting, frontal wedging, or convergence.
Explanation:
The interaction of the air masses leads to the lifting of the air forcefully. These forcefully lifting of air are three types that are: orographic lifting, frontal wedging, or convergence.
orographic lifting: On the higher mountains the air masses move from low elevation to higher elevation as it moves.
frontal wedging: lifting of air takes place when warm air colloids to the cool air and cool air acts, to rise the air.
when air near the surface flows together and is pushed upward when it is squeezed together i known as convergence
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.
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.
