As blood moves away from the heart toward the tissues, the relative size of blood vessels ________, the blood pressure ________,
KonstantinChe [14]
<span>As blood moves away from the heart toward the tissues, the relative size of blood vessels decreases, the blood pressure drops, and the velocity of blood flow slows.

The size of the arteries progressively decreases as they branch out from the major arteries of the body. Once the arteries are the size of the arterioles, the resistance to blood flow increases and velocity of blood flow slows then blood pressure drops.

What is the name of the enzyme used to make rna nucleotides
Likurg_2 [28]
<h2>RNA Polymerase</h2>

Explanation:

  • RNA polymerase, a chemical in the cell, is  answerable for making mRNA from the  right quality. RNA polymerase is like  DNA polymerase, yet it makes a RNA strand  as opposed to a DNA strand. The promoter region of DNA Helix is attached by  RNA polymerase.
  • It pulls in nucleotides that supplement those  on the DNA strand containing the gene of interest. RNA polymerase duplicates one strand of  DNA to make a stretching bit of singlestranded  mRNA. RNA polymerase makes the  mRNA strand in what is known as the 5' to 3'  course.

List at least two possible reasons for the differences you see between the pinch strength of the first two fingers and the secon
andriy [413]

Answer:

The first two fingers may be stronger due to the fact that they are used the most often and could build up more strength and dexterity. Another reason the first two fingers may be stronger could be due to the fact that the ulnar muscle that controls digits 4 and 5 is smaller than the radial muscle.

Explanation:

Pinch strength is a widely used measurement of hand function. A direct relationship between pinch strength and function has been demonstrated and illustrates the importance of hand strength in clinical practice.There is a difference in grip strength in the dominant and non-dominant hands.Dominant hand  is significantly stronger. According to the pinch strength data, he index finger and the thumb are the strongest, the middle finger and the thumb are the second strongest, the ring finger and the thumb are the third strongest, and the little finger and the thumb are last. The difference is the largest between the middle finger and the thumb and the ring finger and the thumb.

The first two fingers may be stronger due to the fact that they are used the most often and could build up more strength and dexterity. Another reason the first two fingers may be stronger could be due to the fact that the ulnar muscle that controls digits 4 and 5 is smaller than the radial muscle.

Difference in the pinch strength may be due to one possible reason that the radial muscle is larger than the ulnar muscle which controls digits 4 and 5. Another reason could be that you generally use the thumb, index, and middle fingers more than the ring and little finger, therefore the first three fingers have more strength and muscle memory.
