Answer:

do not bind the small ribosomal subunit.  

Explanation:

5' CAP is a structure present only in the mRNA molecule. It is characterized as a "helmet" added to the 5' end of the mRNA molecule.

The main function of 5' CAP is to protect mRNA in the cytoplasm (when it leaves the nucleus towards the ribosome). This is because in the cytoplasm can be found the enzymes ribonucleases and fostases that can alter the function of proteins that allow the mRNA to bind to the smaller subunit of the ribosome.

Since tRNA and rRNA do not need to be linked to the ribosome, they do not need the presence of 5' CAP in their compositions.

A sodium-potassium pump within a cell membrane requires energy to move sodium and potassium ions into or out of a cell. The move
Anna71 [15]
The correct answer is: Sodium and potassium ions move by active transport, and glucose moves by facilitated diffusion.

Because sodium and potassium are moved through cell membrane against their concentration gradients, transport requires energy (ATP), so it is active. <span>Glucose is a polar molecule and because the plasma membrane is impermeable to polar molecules transport of this important nutrient is accomplished by carrier proteins. This process is called facilitated diffusion and it is passive transport (doesn’t require energy).</span>

How does tetanic contraction of muscles help to lift objects heavier than our body weight?
Alik [6]

The tetanic contraction of muscles help to lift objects heavier than our body weight by generating force, overcoming resistance.

<h3>What is muscle?</h3>

Muscle is defined as group of tissue combined together in order to form muscles and muscles are the structure maker of the body it means it provide proper structure to the body.

Muscle contraction has been defined as an action potential that travels along with the nerves to the muscle. The beginning of the muscle contraction occurs with signal generated from the nervous system.There are mainly two types of muscle contraction and the situation occur when a muscle contracts and the change in size takes place.

Therefore, The tetanic contraction of muscles help to lift objects heavier than our body weight by generating force, overcoming resistance.

Already know you mean standard scientific notation.

3.05 x 10^3 = 3050

Explanation:

3.05 times 10 to the 3rd power.

First we need to multiply 10 to the 3rd power, the 3rd power is the thousands. So 10×10×10 = 1000.

3.05 × 1000 = 3050
