What happens when a nerve impulse reaches the end of a neuron?
Answer:
Cellular communication
Explanation:
At the end of a neuron, there is a space called the synaptic junction that helps it communicate with another neuron or organ in order to produce a response. When the impulse reaches the end of a neuron usually called the axon terminal, it causes the opening of voltage gated ion channels that causes the influx of ions inside the cells. This in turn will cause synaptic vessicles that contain neurotransmitters to move towards the membrane of the axon terminal and fuse with the membrane then open up to release the neurotransmitters into the synapse (space between the 2 neurons). When this happens, the voltage gated channels close. The neurotransmitters then bind to ligand receptors on the second recieving neuron that cause it to produce an effect like stimulate an organ or produce an impulse . After using up the neurotransmitters, they can be recycled or broken down into metabolytes that are used up by the cell.

Which characteristic of water is most helpful to fish in a lake?
A.
Water freezes at 0°C.
B.
Water molecules are polar.
C.
Two elements make up the compound water.
D.
Frozen water floats on liquid water.
Final answer:
Frozen water floats on liquid water, providing an insulating barrier for fish in a lake.(Option D)
Explanation:
The characteristic of water that is most helpful to fish in a lake is that frozen water floats on liquid water.
When water freezes, it becomes less dense and expands. This causes it to float on the surface of the lake instead of sinking to the bottom. The layer of ice acts as an insulating barrier, providing protection for the fish living in the liquid water beneath.
Without this characteristic, the lake would freeze solid from the bottom up, making it impossible for fish and other organisms to survive.This unique property of water, where frozen water floats, not only forms an insulating barrier crucial for fish survival but also prevents lakes from freezing solid, ensuring the viability of ecosystems and the diverse organisms that rely on liquid water habitats.
the maintainnce of healthy bones depend on the balance of osteoblast and osteoclast activity, predict what would happen if osteoblast activity exceeds osteoclast activity?
Answer:
If the activity of osteoclasts(which demineralize bone) exceeded osteoblast activity(production of new bone), then the bone's mineral content(and thus its mass) would decline, making it weaker.
Explanation:
Osteoblasts and osteoclasts are two main cells participating in bone progressing. Osteoclasts is responsible for aged bone reabsorption and osteoblasts is responsible for new bone formation. The maintenance of helathy bones depend on the osteoblast and osteoclast activity.
If the osteoblast activity exceeds osteoclast activity, then would be harmulful effect on the bones, the bone mineral would be decline and the bones become weaker without osteoclast and osteoblast.

Which of the following terms means a type of thermal injury to the skin caused by heat source?
A. Burn
B. Bulla
C. Bunion
D. Basal Cell Carcinoma
Final answer:
A burn is a type of thermal injury to the skin caused by a heat source, affecting different layers of skin and classified by degrees of severity - first-degree being the least severe and fourth-degree being the most severe.
Explanation:
The type of thermal injury to the skin caused by a heat source is known as a burn. Burns can occur as a result of exposure to extreme heat, radiation, or chemicals, and are classified into various degrees based on their severity. First-degree burns affect only the epidermis, the outer layer of the skin, and are considered superficial. These often heal within a few days without permanent damage. Second-degree burns are more serious, affecting both the epidermis and the dermis, causing blisters and soreness. Third-degree burns penetrate the full thickness of the skin, destroying both the epidermis and dermis, which can lead to significant complications including infection and require medical attention. Lastly, fourth-degree burns extend into the muscle and bone below the skin, and they are usually not painful because nerve endings are destroyed.

Answer:
A solution with HCl would likely have a low pH and a high pOH. Hydrochloric acid or HCl, from the name itself is acidic its pH is always below neutral pH or 7. pH is the measure of the concentration of hydronium ions (H3O+) in a solution while pOH is the measure of the concentration of hydoxide ions (OH-) in a solution. A relationship exist between the two values of a solution where pH + pOH = 14 therefore when the pH is low, consequently, the pOH is high.
Explanation:
hope this helps
A solution containing HCI would likely have a low pH and a high pOH.
How can the pH of the solution be calculated if the pOH is known?In order to calculate the pH, take the negative log of the hydronium ion concentration. To find the pOH, simply subtract the pH from 14. In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14.
How is pH related to pOH?As pH increases, pOH decreases. As pH decreases, pOH increases. Knowing what ion you are measuring on which scale, will tell you whether or not the solution is acidic or basic. Because these scales are related, an equation can be used to explain their correlation.

In which specialized organ of the plant would these cells most likely be found
Answer:
a leaf
Explanation:
These cells will be found in leaf due to the presence of chlorophyll.
What type of cells does leaf have?There are two distinct kinds of photosynthetic parenchyma cells in leaves (palisade and spongy).
Mesophyll Palisade
A particular class of leaf cell created especially for photosynthesis makes up the palisade mesophyll. These chlorophyll-rich cells simply use all of their energy to produce as much sugar as they can. They discharge this sugar into the intracellular region, where it travels to the subsequent class of leaf cell.Spongy Mesophyll
The term "spongy mesophyll" refers to a loose matrix of structural mesophyll cells. Unlike the palisade cells, these cells are not precisely arranged into rows. Instead, they organize into networks and move materials to and from bundles of vascular cells. They can photosynthesize, just as palisade mesophyll leaf cells, but they also serve other purposes.learn more about leaf cells here:

The blue particles will be transported across the cell membrane by simple diffusion, where they move from a higher concentration to a lower concentration without the use of energy. The correct option is A.
The blue particles in the image will be transported across the cell membrane through simple diffusion, which is a type of passive transport. During simple diffusion, substances that are able to move directly through the cell's lipid bilayer do so from an area of high concentration to an area of low concentration until equilibrium is reached. This process does not require energy from the cell. In the case of the blue particles, if they are small and nonpolar, they will move directly across the membrane from outside the cell to inside the cell if they are more concentrated outside the cell, or vice versa. Therefore, the correct answer is A. The substances will move directly across the membrane from outside the cell to inside the cell.
