Answer:What is the main function of osmosis? Osmosis helps in stabilizing the internal environment of the organism by balancing the levels of water and intracellular fluids. Also, the nutrients and minerals enter the cell by osmosis which is necessary for the survival of cells.
Explanation:
Osmosis maintains the osmotic pressure in cells. the answer to this question is options A and B.
Osmosis is essential for the cells due to two reasons:
1. Cells are made up mostly of water-based fluids. The process of osmosis involves the movement of water molecules from a region with a lower concentration of solutes to an area with a greater concentration of solutes through a semipermeable membrane. This aids in preserving the equilibrium of water within and outside the cell, ensuring that the cell remains hydrated and performs as intended.
2. Sugar-based fluids are the main component of cells' fluids. Osmosis also affects how much sugar and other solutes are present inside cells, helping to control their concentration. Osmosis will cause water to enter the cell if the concentration of sugar inside the cell is higher than the outside, diluted the sugar, and maintain equilibrium.
Therefore the correct answer is options a and b.

what happens to the neuron when u do drugs
Answer:
Explanation:
well different kinds of drugs can affect neuron activity an example is if you take pain pills it blocks the neurons that sense pain other drugs can give you high levels of dopamine, dopamine is the hormone that makes you feel good. that is why drug addictions are serious, and many cannot stop the addiction because it makes them feel good. and if you take the same dose over time your body gets a tolerance to the drug and you need a higher dose every time to get the same feeling and that can lead to an overdose or even death.

Answer:
Star A
Explanation:
If you look directly at the diagram, the dwarf stars are labeled under 'A' and are the least in mass and temperature.
Being the smallest and coldest, dwarf stars most commonly have red coloration, which would make them the obvious choice.
Star A which is a dwarf star has the coldest temperature, and therefore is a red star since red stars are the coldest stars.
What are stars?Stars are a large self-luminous bodies whichbpriducw large amounts of heat energy and light energy as a result of the nuclear reactions occurring within them.
Stars have different colors and different sizes.
Red stars are the coldest stars and also the least massive.
From the chart, Star A which is a dwarf star has the coldest temperature, and therefore is a red star.

8. What is one similarity between human skeletal muscles and some bacteria?
A. Both carry out autotrophic nutrition when food becomes scarce in the environment,
B. Both produce lactic acid when oxygen is not available for respiration.
C. Both reproduce asexually, using binary fission and regeneration.
D. Both lack a nuclear membrane surrounding the chromosomes.
Answer: B
Explanation:
Human skeletal muscles and some bacteria both produce lactic acid when oxygen is not available for respiration, which is similar. The best choice is B.
What are skeletal muscles?Skeletal muscles enable humans to move and perform daily activities. They are essential to breathing mechanics and help preserve balance and posture. They also protect the vital organs of the body.
Skeletal muscle fibers can be found in muscles that are attached to bones. They are consciously regulated and have a striated appearance.
Lack of oxygen causes both skeletal muscle and bacteria to produce lactic acid through respiration.
Since both produce lactic acid when oxygen isn't available for respiration, option B is the proper response.

Explanation:
Meiosis makes genetic variety possible. It makes sperm & egg cells called gametes. Each gamete has 23 chromosomes. To make a diploid cell two gametes (sperm & cell) come together.
During prophase 1 the chromosomes pair up with their homologous pairs so they can transfer their genetic information and exchange it between each other. It makes recombinant chromosomes that influence the genetic diversity between the same people.
Now they are in metaphase 1, the chromosomes are in pairs in the middle of the cell. In anaphase 1, the chromosomes are pulled away by the spindle fibers. Then in telophase 1, there are two formed nuclei. Cytokinesis 1 then splits the cytoplasm.
Now they are in meiosis 2. During prophase 2, there are chromosomes and the spindles are starting to form again without crossing over like in prophase 1. In metaphase 2, chromosomes are going to line up in the middle in both cells unlike during metaphase 1 where the chromosomes were only in pairs. In anaphase 2, only the chromatids are being pulled away by the spindle fibers. Next in telophase 2 the nuclei reform and the 2 cells are each going to divide into 4 cells. Finally, cytokinesis completely splits the cytoplasm.
Keeping in mind that each sex only produces one type of gamete cell (sperm or eggs), and of the independent assortment and crossing over of chromosomes, the end result will be diversity.

Which of the following correctly identifies a lymphatic organ and describes how it
can fight cancer? (2 points)
1) Lymph vessel; removes fluid from tissues
2) Lymph trunk; returns lymph to the blood
3) Spleen; replaces damaged red blood cells
4) Thymus; exposes lymphocytes to antigens
All of the statements correctly identify a lymphatic organ. In vertebrates, the lymphatic organs, also known as the lymphoid system, are an organ system that is a part of the immune system and works in conjunction with the circulatory system.
The Lymphatic OrgansLymphatic vessels, which are found all over your body and transport lymph away from tissues, are a network of capillaries (microvessels) and a huge network of tubes.By emptying into the corresponding subclavian veins, the lymph ducts, which are formed by the lymph trunks, restore lymph to circulation.Red blood cells that are outdated or damaged are eliminated by the spleen, which also removes cellular waste from circulation.Training specific white blood cells known as T-lymphocytes or T-cells is the thymus gland's main job.Hence, all of the statements correctly identify a lymphatic organ.
How lymphatic system fights Cancer?Regional lymph nodes, which are predictive of distant organ metastases and poor survival, are accessible to tumor cells via lymphatic arteries.As the lymph fluid moves through the lymph nodes, it is filtered. B cells and T cells, two types of white blood cells, assault any viruses or bacteria they discover in the lymph.To learn more about the Lymphatic System refer to:

What happened? A corpse is discovered in an enclosed room, there are no open windows, yet blowfly larva (stage 2) are found on the body. What does this tell you about the corpse?
Answer:
The corpse was deposited into the room from somewhere else
Explanation:
The larva could not have spontaneously emerged from the corpse if the blowfly had not somehow perched and laid its egg on it. Since there are no open windows, and perhaps, other openings to the room; the only plausible explanation for the emergence of the blowfly larva would be that the corpse was deposited into the room from somewhere else. From the initial location, the blowfly had perched and laid its egg on the body and the eggs only hatched while in the enclosed room.
The corpse changed into deposited into the room from someplace else as the larva couldn't have spontaneously emerged from the corpse if the blowfly had now no longer in some way perched and laid its egg on it.
Since there aren't any open windows, and perhaps, different openings to the room; the best potential cause of the emergence of the blowfly larva might be that the corpse changed into deposited into the room from someplace else. From the preliminary location, the blowfly had perched and laid its egg at the frame and the eggs best hatched even as withinside the enclosed room.
