Answer:
Sixteen years old is the age where the biggest difference between the average height of boys and girls can be observed. This is a difference of approximately 5.7 cm.
Explanation:
As we know, for biological reasons, boys and girls have different growths and different development in their bodies. However, the growth and development of boys and girls during childhood is very similar and only starts to look different even from adolescence, where individuals have great structural differences.
At 16 years of age, boys and girls have the greatest mean difference in height. While in previous years this difference was on average 1 centimeter, at 16 years old, girls are 150.8 cm tall on average, while boys are 156.5 cm tall.

Cells in the human eye send nerve impulses to the brain that causes the pupil to constrict. This is an example of a reaction to the light stimuli. Thus, the correct option is B.
Pupils are the part of eye which respond to three distinct kinds of stimuli which include their constriction in response to brightness of light, this is called as the pupil light response, constrict in response to near fixation which is known as the pupil near response, and dilate in response to increases in the arousal and mental efforts, either these are triggered by an external stimulus or occur spontaneously.
Light is the stimulus and the impulses in response to this reach the brain through the optic nerve and the response due to this is conveyed to the pupillary musculature through autonomic nerves which supply the eye.
Therefore, the correct option is B.

the leaves are yellow and there is splotchy mottling all over the leaves. Some of the leaves are falling
off prematurely. After the fruit ripens, it starts to turn green.
What is the disease ?
Answer:
Citrus greening disease
Explanation:
The symptoms sound like citrus greening disease. This disease is characterised by yellowing of the veins in the leaves, splotchy mottling of the entire leaf, leaves that fall off too early, and fruit that can turn green and tastes bitter.
Citrus greening disease is caused by a bacteria, and transferred by insects such as the Diaphorina citri.
Answer:
oxidation
Explanation:
From the moment we perform body movements, there is a greater demand for oxygen. This is due to the need for oxidation of energetic substrates such as free fatty acids and circulating glucose. Thus, aerobic metabolism is potentially increased to supply the energy required by muscle contractions, whatever their intensity. From this we can say that breathing hard during exercise brings oxygen to the muscles, which helps the oxidation process release energy to fuel the workout.
