Answer:
Starch molecules are too large to diffuse into cells.
Explanation:
As mentioned "Starch molecules are actually long chains of glucose molecules"
Thus they are broken down to glucose To make their transport (by diffusion) easier.
According to the research, the correct option is control. Experiments are carried out to test a hypothesis by changing one variable at a time and including an unchanged variable termed a <u>control</u>.
<h3>What are
Experiments?</h3>
It is the process by which one or more variables are intentionally manipulated by carrying out actions aimed at discovering or verifying certain phenomena.
In this sense, its basis is in the manipulation of the variables that are considered relevant, the control of strange variables and the randomization of the rest.
Therefore, we can conclude that according to the research, the correct option is control. Experiments are carried out to test a hypothesis by changing one variable at a time and including an unchanged variable termed a <u>control</u>.

Answer:
b
Explanation:
Nutrient pollution can create dead zones areas in water with little or no oxygen where aquatic life cannot survive. Also known as hypoxia, these areas are caused by algal blooms consuming oxygen as they die and decompose.
I believe the correct answer is B. Vibrate with the frequency of the received sound.
<h2>Explanation:</h2>
The ear is divided into 3 sections: The outer ear, the middle ear and the inner ear. The outer ear is funnel shaped leading into the head to collect sound waves and concentrate it to the middle ear. The middle ear contains the eardrum (tympanic membrane) which vibrates in response to the sound waves.
<h2>Further Explanation:</h2>
The middle ear contains the eardrum(tympanic membrane) which is a special type of membrane that is thin and taught to vibrate to the slightest sound waves. When the sound waves cause the vibration of the tympanic membrane depending on different frequencies, it will cause the 3 bones attached to it ( malleus, incus and stapes) to vibrate at the frequency the membrane vibrated. This motion will cause the round window of the inner ear to vibrate at the same frequency. The round window is connected to a structure called the organ of corti that contains many very sensitive hair cells. The inner ear is filled with fluid including the organ of corti. The vibration of the inner ear is transmitted into this fluid and the back nd forth motion of the fluid will cause vibrations on the hair cells in the base of the organ of corti. These cells are specially adapted and transmit the vibrations as electrical signals to the sensory neurons attached to them. These neurons then will carry the converted sound energy to the brain via major cranial nerves where the brain will interpret these signals as sound waves. Interpretation is continuous and very fast and that is why a person can hear things simultaneously. These hair cells are the ones that get destroyed when listening to loud music making a person go deaf. Bomb blasts and gunfire sound also tear the tympanic membrane and the destroy the sensory cells and this is why many war veterans have hearing problems.
