Answer:

The correct answer is option A. "The rate of diffusion would be faster for the right cylinder".

Explanation:

The rate of diffusion is defined as the amount of molecules that are exchanged from a body to another. The rate of diffusion is directly proportional to the ratio of surface area to volume , where the higher the ratio of surface area to volume the higher the rate of diffusion. In this case, a sphere have a ratio of surface area to volume equal to 0.3 m, and a right circular cylinder have a ratio of surface area to volume equal to 2.1 m. Since the right cylinder have a higher ratio of surface area to volume, the rate of diffusion would be faster for the right cylinder.

Answer:

Explanation:

Add radio labeled actin sub units to a mixture of actin filaments in which conditions are favorable for polymerization. This would enable you to identify the plus end of actin filaments.

Actin filaments are linear polymer of globular actin sub units Actin filaments have polarity. This means that the two ends can be identified due to structural differences.

Within a double-stranded DNA molecule, adenine forms hydrogen bonds with thymine and cytosine forms hydrogen bonds with guanine.

avanturin [10]

Answer:

The correct answer will be option- permits complementary base pairing

Explanation:

DNA contains four types of nitrogenous bases which pair with one another, identified by Erwin Chargaff.

Chargaff suggested that adenine binds thymine forming two hydrogen bonds and cytosine binds guanine forming three hydrogen bonds.

This base pairing between the complementary groups is known as a complementary base pairing which plays an important role in DNA.

The complementary base pairing allows the formation of the helical structure of DNA, the base pairs to be arranged in most energetically and favourable way and replication and transcription processes.

Thus, permits complementary base pairing is the correct answer.

The tensor fasciae latae stabilizes the hip joint and the __________ joint.

vladimir2022 [97]

Answer:

Knee.

Explanation:

Joints may be defined as the articulation by which the bones meet together and constitute the skeletal system. These joints helps in the particular movement of the body.

Tensor fasciae latae muscle is present in the thigh. This muscle is attached with tibia and innervated by the super gluteal nerve that supplies the blood artery. This muscle plays an important role in the stabilization of the knee and the hip joint.

Thus, the correct answer is option (c).

Dangerous decreases in respiration, heart rate, and body temperature typically begin with a BAC of approximately __________ .

liberstina [14]

Answer: c. 0.15%

Explanation:

The blood alcohol concentration or BAC refers to the percentage of alcohol present in the bloodstream. The value of blood alcohol concentration of 0.15% is very high. It will affect the balance of voluntary muscles, walking and talking will also become difficult. The person will experience a severe increase in the rate of heart, the body temperature will rise, the person will experience irregular breathing and the bladder control will become weak.
