Mitochondria is the powerhouse of cell therefore, cell creates many 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.

Fixed cells are refers to static cells that remain unchanged over time while living cells refers to dynamic cells that move and change over time.

Fixed cells are cells that are preserved in a condition that is as close to “life-like” as possible.

These cells usually die during this process, but their shape and contents are maintained for imaging purposes.

Further preparation for fixed cells are far easier to perform than live cells.

On the other hand, living cells are cells which are still alive and this makes cell imaging difficult.

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".

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.

Recent finds include a nearly complete wolf skeleton, tusk and bones from a woolly mammoth, and also part of a woolly rhino skull.

Animals did not necessarily live at the same time. Scientists suggest that they fell into a common grave over thousands of years or that their bones were taken to the cave by predators. after these events, the ice age came and froze all the bones of these animals.

With this information, we can conclude that recent discoveries include an almost complete wolf skeleton, tusk and bones from a woolly mammoth, and also part of a woolly rhino skull.

Answer:

1. The French and Indian War began in 1754 and ended with the Treaty of Paris in 1763. The war provided Great Britain enormous territorial gains in North America, but disputes over subsequent frontier policy and paying the war's expenses led to colonial discontent, and ultimately to the American revolution.

2. In the long-term, the Revolution would also have significant effects on the lives of slaves and free blacks as well as the institution of slavery itself. It also affected Native Americans by opening up western settlement and creating governments hostile to their territorial claims.

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.

Explanation:

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.

Diabetes 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.

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.
