10 facts about “molecules”
drag the labels to their appropriate locations on the diagram of the neurons below. use targets of group 1 to indicate the components of neurons. use targets of group 2 to indicate the locations of gated ion channels.
Neurons are cells in chauge of synapsis. a)cell body / b)myelin sheath / c)synaptic terminal / d)axon hillock / e)nucleus / f)location of voltage-gated channels / g)location of ligans-gated channels / h)axon / i)dendrite
-------------------------------
Most neurons are composed of a cell body, dendrites that are cytoplasmic extensions that receive impulses from other cells, and an axon that is a long formation capable of conducting the electrochemical signals.
Neurons transmit nervous impulses.
Every neuron forms connections with other neurons. These connections are known as synapsis.
During synapsis, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the other neuron.
Once it reaches the target, it binds to its receptors in the postsynaptic membrane, causing ion channels to open.
This binding produces a depolarization of the cell called an excitatory postsynaptic potential.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.
When the electrical stimulus is applied to the axon's membrane, it produces depolarization by activating the sodium voltage-dependent channels all along the axon.
Besides, there is an increase in sodium permeability.
Depolarization propagates to inactivated regions adjacent to the membrane opening more sodium channels.
The fiber diameter and the conduction velocity are closely related, exhibiting a directly proportional relationship. Mielinized fibers are thick, and their conduction velocities are very fast.
The conduction velocity sharply increases in myelinated fibers. This is because of the high concentrations of sodium channels in the Ranvier nodes that are not myelinated areas, and the diameter of the axon becomes thinner.

On the internet, read about the Clean Air Act of 1990:
a. Summarize what it says.
b. How should it help with the problem of acid rain?
c. How successful has it been in reducing the harmful chemicals from the burning of fossil fuels that cause acid rain?
d. What can you do personally to help alleviate the problem of acid rain?
3. Find two examples of actual ecological places that have been affected by acid rain. Tell their location and describe what happened.
Acid rain is formed when gases such as SOx and NOx are released by burning fossil fuels.
The clean air act has to do with the reduction of the gases that lead to acid rain such as SOx and NOx. The full implementation of the legislation ought to reduce the occurrence of acid rain.
However, since the introduction of the act in 1990, reduction in acid gas pollution has not reduced significantly since acid gases are still produced by the burning of fossil fuels.
To help alleviate the problem of acid rain, I must reduce my use of gasoline powered vehicles and embrace vehicles that depend on renewable energy sources and clean fuels such as hydrogen fuel.
Eastern Europe countries such as Poland and Scandinavia have been severely affected by acid rain. The pH of water bodies in these areas are unusually low.

The concentration of lactic acid in the student's
muscle tissue was most likely greatest during trial
A) A В) В
C) C D) D
Option D has the highest concentration of lactic acid in the student's muscle tissue.
We can arrive at this answer because:
Lactic acid increases its concentrations in the muscle due to a high physical effort in anaerobic conditions.This promotes a lack of oxygenation in the muscle, which through contractions, causes the cell to partially catabolize glucose molecules.The result of this is the creation of two pyruvic acid molecules, which will react with NADH2 molecules, creating lactic acid, which will build up in the muscle as the exercise continues.As we can see in the information presented above, option D shows the performance of flexions with more intensity and for a longer period, which justifies a greater accumulation of lactic acid in the muscle.
It is important to remember that the accumulation of lactic acid in the muscle is a negative situation and that it can cause muscle pain and fatigue.

functions of bowman's capsule and materials absorbed in the bowman's capsule
Answer: The structural and functional unit of the kidney is called a nephron. It consists of two main parts viz. the glomerulus and the tubular system. The glomerulus is composed of Bowman’s capsule and a tuft of leaky blood vessels encapsulated by the Bowman’s capsule.
Glomerulus capsule is a tuft of capillaries that are found inside the capsule of Bowman. Bowman’s capsule is a sac-like organ that is present at the nephron’s tabular end, encapsulating glomerulus in it.
The primary purpose of the glomerulus is filtration. The leaky vessels filter into the glomerulus almost all the water, electrolytes, small proteins, nutrients such as sugar etc and excretory products such as urea, etc.

cell membrane present ribosomes present lysosomes present nuclear membrane present
Animal
Plant
Virus
prokaryote
Answer:
animal
Explanation:
Animal: All components present. Plant: All components present. Virus: Only cell membrane present. Prokaryote: Cell membrane present, others absent.
Option (1) is correct.
Animal: Cell membrane, ribosomes, lysosomes, and nuclear membrane are present. Animals are eukaryotic organisms with membrane-bound organelles and a well-defined nucleus.
Plant: Cell membrane, ribosomes, lysosomes, and nuclear membrane are present. Plants are also eukaryotic organisms and share similar cellular structures with animals, including membrane-bound organelles and a nucleus.
Virus: Only a cell membrane may be present, depending on the type of virus. Viruses are acellular particles that lack organelles and a nucleus. They consist of genetic material (DNA or RNA) enclosed in a protein coat called a capsid. Some viruses also have an outer lipid envelope derived from the host cell's membrane.
Prokaryote: Cell membrane is present, but ribosomes, lysosomes, and nuclear membrane are absent. Prokaryotes, such as bacteria, lack a nucleus and membrane-bound organelles. They have a simpler cell structure, with genetic material located in the cytoplasm and ribosomes involved in protein synthesis. Lysosomes, which are membrane-bound organelles involved in digestion, are not present in prokaryotes.
