What two things can cause a DNA helix to separate into two strands
during PCR?
Answers
How do the strands separate during PCR? The DNA polymerase breaks the hydrogen bonds between the two strands. The primers separate the strands during the annealing step. The high heat of the denaturation step breaks the hydrogen bonds between the two strands.
The two things that can cause a DNA helix to separate into two strands during PCR are initiation and unwinding.
What is PCR?PCR is a polymerase chain reaction. The process is making more DNA sequences from a DNA sequence. The process is done in a PCR machine. The DNA template is put in the machine and a copy of the DNA is made.

Which of the following is one of the ways that cellular respiration and
photosynthesis are opposite processes? *
•Photosynthesis releases energy, and cellular respiration stores energy.
•Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration
puts it back.
•Photosynthesis removes oxygen from the atmosphere, and cellular respiration puts it
back.
•Photosynthesis consumes glucose, and cellular respiration produces glucose.
Answers
Answer:
•Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.
Explanation:
Photosynthesis:
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
Carbon dioxide + water + energy → glucose + oxygen
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.
Cellular respiration:
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
In this way it release the carbon dioxide back into atmosphere.

What is photosynthesis?Plants absorb water and carbon dioxide from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.
Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.
The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
Therefore, light energy where you have it and Move glucose to where carbon dioxide is and Move carbon dioxide to where glucose.

i) predict which of the liquids would cause the largest decrease in mass of potato stick
PLEASE PLEASE HELP ME I HAVE 10 MINUTES ONLY, I WILL GIVE YOU THE BRAINLIEST!!
Answers
Answer:
1 mol per dm3 sodium chloride solution
Explanation:
The liquid that would cause the largest decrease in the mass of the potato stick would be the one with 1 mole per dm3 sodium chloride solution.
The water potential of a solution depends on the molarity of the solution, the higher the molarity, the lower the water potential and vice versa. Hence, a solution with higher molarity has the tendency to osmotically draw more water from the potato stick than a solution with lower molarity.
Therefore, the potato stick will have the largest decrease in mass in 1 mol per dm3 sodium chloride when compared to the 0.5 and 0.1 mole per dm3 solutions.

The process of decomposition increases the amount of carbondioxide gas in the atmosphere.
The process of decomposition greatly affect the amount of carbondioxide in the atmosphere because in the process of decomposition, carbondioxide is released in the atmosphere which is added to the carbondioxide present in the atmosphere.

Kim and jullio go to a raceway to watch Julio's older brother, Raul compete. Raul's car cover 2.5km in 12 seconds and reaching a speed of 180km/hr.
Let us assume that following:
S=distance
U=initial velocity
V=final velocity
A=acceleration
T=time taken
Given that:-
S=2.5 km
S=2.5×1000 mtr
S=2500 mtr
T=12 seconds
V=180km/hr
=180×1000/3600 m/sec
V=50 mtr/sec
U=0 because in starting his car in rest position
Equation which use for calculations of acceleration,
S = UT + 1/2AT^2
2500 = 0×12 + 1/2A(12)^2
2500 = 0 + 1/2×A×144
2500 = 72×A
A = 2500/72
A = 34.72 m/sec^2
It means when rauls starts the race it's car is in rest position and after that it accelerate at the rate of 34.72 m/sec^2

d: Heat was transformed by radiation, resulting in an increase in kinetic energy.
Answers
Answer:
The correct answer is - a: Heat was transferred by conduction, resulting in an increase in kinetic energy.
Explanation:
Conduction is ne of the het transfer method where particular substance is heated and increase the kinetic energy which leads to the molecules to vibrate more and move or jump to the particles present in neughbouring substance and transfer some part of the enrgy.
This transfer is a continuous process untill both end become of same temperature of have same kinetic energy, In this case, heat is tranfer ffrom hand to gloves and to the other hand which are hold together after activating them.
