It is correct because lysosomes are needed to digest the unwanted materials.
If light color is a recessive trait and the trees stay dark forever, could the light colored moths eventually become extinct? Why or why not?
Answer:
The light moths could become extinct eventually
Explanation:
If trees stay dark forever the light moths are easier to prey upon and eventually negative selection pressure will decrease the population of light moths until it is virtually nonexistent.
For a real life case of this, look into pepper moths and the Industrial Revolution.
If the light-colored trait is truly recessive, the moths may still carry the gene and could reappear in future generations.
What is a recessive trait?A recessive trait is a genetic characteristic that is only expressed when an individual inherits two copies of the recessive gene, one from each parent. In other words, a recessive trait is only observable when the dominant version of the gene is absent.
For example, if a person inherits a dominant brown-eye gene from one parent and a recessive blue-eye gene from the other parent, they will have brown eyes, as brown is the dominant trait. However, if both parents pass on the recessive blue-eye gene, the individual will have blue eyes, as there is no dominant gene present to override the recessive gene.

Answer:
A.presynaptic cell B.postsynaptic cell C.neurotransmitters
Explanation:
Your welcome.
The neuron that transmits the impulse is called the "presynaptic neuron", and the cell receiving the impulse is called the "postsynaptic neuron".
What are neurons?Neurons, also known as nerve cells, are specialized cells that transmit electrical and chemical signals throughout the body. They are the basic units of the nervous system, which includes the brain, spinal cord, and peripheral nervous system.
Thus, the neuron that transmits the impulse is called the "presynaptic neuron", and the cell receiving the impulse is called the "postsynaptic neuron". When a nerve impulse arrives at the axon terminal of the neuron, it triggers the release of molecules called "neurotransmitters". These molecules diffuse across the synapse and bind to receptors on the next cell.

you see a mosquito land on your hand and swat at it. A signal passes through many parts of different neurons to make this happen. Which component of the nervous system is the last to be involved in this process?
A. Dendrites in sensory neurons
B. Axons in motor neurons
C. Axons in sensory neurons
D. Dendrites in motor neurons
The reflex arc is the sequence of events since the body receives an external stimulus (seeing a mosquito landing on your hand) until it reacts (swapping at the mosquito). In the exposed example, the last components in the NS involved in the process are the Axons in motor neurons.
----------------------------------------
The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.
In general terms, a stimulus of varying nature reaches the body, the peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-. The CNS processes the information and sends another signal as a response to the stimulus.
Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.
The neurons involved in the mechanism are:
• Afferent or sensorial neurons
• Interneurons
• Efferent or motor neurons
Action:
• Ascending branch
The stimulus reaches the body and is received by the specialized sensory receptors. Afferent neurons, placed in the dermis and epidermis, receive this information from receptors, react and send it to the central nervous system as nerve impulses.
• Descending branch
Interneurons in the CNS, process the information and send a motor response. Efferent neurons carry the response from the CNS to the effector organs, which might be either a muscle or a gland.
Finally, the target tissue responds to the stimulus as a contraction -muscle-,or as hormones release -gland-.
A motor neuron is formed by a cellular body, dendrites (cytoplasmic extensions that receive stimuli from other cells), and a long axon that is capable of conducting the electrochemical signals. The axon brunches out into several extensions when it approaches the muscle. At the end of each brunch, the axon is inserted in the muscle fiber surface, composing neuromuscular join. This is the last part of the NS involved in the process before the muscle contracts.

What are the processes in which material move through a cell?
The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes. Substances diffuse from areas of high concentration to areas of lower concentration; this process continues until the substance is evenly distributed in a system.
Karissa is conducting an experiment on the amount of salt that dissolves in water at different temperatures. She repeats her tests several times using the same procedure. What can Karissa do to further increase confidence in the results of her experiment?
Answer:
She could time how long it takes for each amount of salt dissolves in the waters. (as well as keep each amount of salt the same if she was not doing that already.)
Explanation:
This way, she could observe which water is best for dissolving solvents and which is most affective in the shortest amount of time. If she was not timing how long it takes for salt to dissolve in different temperatures of water, then the experiment may as well have been useless unless there is somehow a different objective.
Answer:
she could make sure the experiment follows a specific procedure that allows other scientists to produce the same findings

Why do you think the cell creates many mitochondria?
Mitochondria is the powerhouse of cell therefore, cell creates many mitochondria.
What is mitochondria?The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular).
Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria (ATP). Small chromosomes found in mitochondria are found there.
Organelles that are membrane-bound include mitochondria, however they are membrane-bound with two distinct membranes. And for an intercellular organelle, that's extremely remarkable. Those membranes provide the fundamental function of mitochondria, which is to produce energy.
Therefore, Mitochondria is the powerhouse of cell therefore, cell creates many mitochondria.

Which statement may plausibly explain type II diabetes, but not type I diabetes?
The statement that may explain type II diabetes is that a protein that is normally activated by the insulin receptor does not perform its function. That is option C.
Causes of type II diabetesDiabetes mellitus is a metabolic disorder that occurs due to the inability of the body cells to utilize the insulin produced as seen in type II diabetes or the inability of the pancreatic cells to produce insulin in enough quantity.
In type II diabetes, there is presence of insulin in the bloodstream of the patient but the body cells are not able to make use of it to metabolize glucose.
This is because when the protein that is activated by insulin receptor fails to function, problems with insulin signalling can occur which impairs the proper management of glucose levels in the blood.
Therefore, the statement that may explain type II diabetes is that a protein that is normally activated by the insulin receptor does not perform its function.

The extra energy is converted to fat and stored until needed.
Answer:
The correct answer is - The extra energy is converted to fat and stored until needed.
Explanation:
When someone intakes more carbohydrates than they need at a particular time body converts the excess amount of the carbohydrate into glycogen and stored in the liver cells.
One glycogen level is full the insulin starts converting the carbohydrate into fatty acids that move to different parts of the body and stoored like adipose tissue in the belly and thigh.
Thus, the correct answer is - The extra energy is converted to fat and stored until needed.
