Answer:
IF a high concentration of fertilizer is used, THEN orchid plants will grow best
Explanation:
The hypothesis in an experiment is the testable explanation given in support of an observer problem. It is a predictive statement that aims at proferring a possible solution to a problem or answer a question asked. The hypothesis must be able to be tested via experimentation as this is one important feature all hypotheses must possess. A hypothesis is usually written in an "IF, THEN" format.
In this question, an investigation is being carried out to know the effect of a certain amount of fertilizer on the growth of orchids in a greenhouse. A possible explanation/hypothesis will be:
IF a high concentration of fertilizer is used, THEN orchid plants will grow best.
This can be accepted or rejected depending on the outcome of the experiment.
Meissner's corpuscles
Pacinian corpuscles
free nerve endings
Answer: Free nerve endings
Explanation:
A free nerve ending can be defined as the bare nerve endings that are unspecialized afferent nerve fibers which sends its signal to sensory neuron.
The main function of these nerve endings is to being the signals to the brain from the periphery of the body. They can sense itch, hair movement, temperature, pain et cetera.

The brain sends appropriate responses to muscles and glands through the nervous system.
When the brain responds to messages by sending appropriate responses to muscles and glands, it does so through the nervous system.
The nervous system is a complex network of nerves and cells that transmit signals between different parts of the body. The brain plays a vital role in processing these signals and sending out appropriate responses.
For example, when you touch a hot stove, sensory receptors in your skin send a message to your brain, which then signals your muscles to quickly retract your hand. This quick and automatic response is coordinated by the nervous system.

Answer:
Polygenic therapies are more likely to show unintended effects in other regions of the genome likely resulting in harmful diseases.
Explanation:
Gene therapy involves biotechnological techniques that add or remove gene sequences in the genome. These are typically used in eliminating harmful genes that cause genetic diseases or disorders and are generally thought to improve an individual's quality of life.
Polygenic traits are controlled by several genes. Similarly, polygenic diseases may be caused by variations in several gene sequences. These include hypertension, heart disease, and diabetes. Polygenic therapies are more likely to show unintended effects in other regions of the genome, leading to other deleterious disease-causing effects.
