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
Answers
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.

How many base pairs per turn of the helix would most likely correspond to a positively supercoiled DNA molecule
Answers
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
Answers
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.
Studies of conjugation in multiple Hfr strains revealed that the bacterial chromosome was: circular. single stranded. directional. None of the above
Answers
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.

The exchange of substances between the blood vessels and the surrounding tissues can only happen in the ___________.
Answers
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.

circuit is 12 voltsvhat's the magnitude of the current?
12
36 amperes
0.25 amperes
9 amperes
4 amperes
Answers
Answer:
4 amperes
Explanation:
Using the formula; V = IR
Where;
V = voltage (volts)
I = current (amperes)
R = resistance (ohms)
From the formula; I = V/R
According to the information provided in this question, the resistance of circuit (R) is 3 ohms while the voltage (V) produced by the cell in the circuit is 12 volts.
Therefore, I = 12/3
I = 4 A or amperes.

How does snake venom kill prey? How is venom toxicity measured?
Answers
Answer:
1.Snakes use their venom cautiously, injecting amounts sufficient to disable prey or to defend against predators. Snake venom works by breaking down cells and tissues, which can lead to paralysis, internal bleeding, and death for the snake bite victim.
2.Snake venom and other toxins' strength is measured using the LD50 (lethal dose 50%) test. ... The amount of test substance that kills half the animals gives the LD50 figure. LD50 figures are used, in theory, to indicate the standard toxicity value for each chemical.

What are three types of forceful lifting of air?
Answers
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

Explain how covalent bonds and hydrogen bonds hold together a strand of DNA
Answers
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.
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
Answers
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.
[FW.04H]The table below shows the data collected by a student about the number of gallons of water wasted per year by a leaking faucet.
Faucet leaking rate (drips per minute) 5 10 20 30 60

Describe how many genes and chromosomes can be found in the human body, and how they influence physical appearance and other traits.
Answers
I don’t really have an answer but I have an explanation
Explanation: In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. These pairs of genes then determine certain physical features or traits.
Humans have 46 chromosomes and around 20,000-25,000 genes that determine physical appearance, behavior, and other traits.
What are chromosomes?The human body has 46 chromosomes, which are made up of long strands of DNA that contain the genetic information for an individual. These chromosomes are arranged in 23 pairs, with one chromosome from each pair inherited from each parent.
Each chromosome contains thousands of genes, which are segments of DNA that code for specific proteins that carry out various functions in the body. Genes play a key role in determining an individual's physical appearance, as well as other traits such as susceptibility to certain diseases and personality traits.
Inherited variations or mutations in these genes can lead to differences in physical appearance and traits between individuals. Additionally, environmental factors can also influence the expression of certain genes, further contributing to individual differences.
