Answer:

Windmills (wind turbines) are generally made up of 2-3 blades that are also considered as the propeller-like blades and this is fixed about the rotor at the top of a pillar or tower at a height of about 80-100 feet. This is because the wind is generally fast at about this height.

The rotor is again fixed to a major shaft, and when the prevailing wind is high enough in that area then the turbines rotate and due to this rotation, the generator within the major shaft starts spinning thereby produces the electricity. Thus they are one of the efficient ways of using wind energy.

Answer: Adrenaline, also known as epinephrine, is a hormone and medication. Adrenaline is normally produced by both the adrenal glands and a small number of neurons in the medulla oblongata, where it acts as a neurotransmitter involved in regulating visceral functions (e.g., respiration).It plays an important role in the fight-or-flight response by increasing blood flow to muscles, output of the heart, pupil dilation response and blood sugar level. It does this by binding to alpha and beta receptors.[

What does not move across axons?
Maurinko [17]

The correct answer is A. neither electrons or axons.

An axon is a long, slender nerve fiber of a neuron. Its function is to conducts nerve impulses away from the cell body of a neuron to the dendrite of other neuron. A nerve impulse is an electric signals. A nerve impulse is due to the movement of ions in and out of the cell. It does not allows electrons or other axons to move across the axons. Thus, electrons and axons do not move across the axons.

yulyashka [42]

The given question is missing the chart or the details of blocks, each week. However, the details of the blocks are as follows:

1week = 2blocks

2weeks = 3blocks

3weeks = 5blocks

4weeks = 4 blocks

5weeks = 5blocks

Oweeks = 5blocks

7 weeks = 3blocks​

Answer:

The correct answer is - 13.5 cm.

Explanation:

According to the details of the blocks, the number of blocks each week as follows:

1week = 2blocks

2weeks = 3blocks

3weeks = 5blocks

4weeks = 4 blocks

5weeks = 5blocks

Oweeks = 5blocks

7 weeks = 3blocks​

Adding total blocks would be :

2 +3 + 5 + 4 + 5 +5 + 3 = 27 blocks

Each block equals 5 mm of growth.

Then, 27 x 5 = 135 mm

135mm = 13.5 cm

Thus, the correct answer is : 13.5 cm
