Answer: seizure is an abnormal electrical activity in the brain shown by an animal. In a typical seizure, the body of the animal shakes rapidly and uncontrollably. Water can be a cause of a seizure whentoo much water, by osmosis, moves into the brain. The increase in pressure of the brain will cause the fire rate of neurons to increase or decrease which leads to seizures. If the electrical signals in a neuron increases or decrease and are not at the normal level it will cause a seizure. Diffusion so the movements of atoms, ions, or molecules from an area of high concentration to an area of low concentration. The difference in concentration across the cell membrane is a concentration gradient. So, the molecules diffuse down their concentration gradient from areas ofhigh concentration to areas of low concentration. Sodium ions are impermeable and cannot diffuse through the cell membrane, which is the same for water molecules, but water molecules can pass the membrane through facilitated diffusion with the help of aquaporins.

What are 2 fundamental principles of evolution
Evolution has four principles:
- Inheritance
- Variation
- Selection
- Time
Inheritance refers to the ability of the individuals of the population to pass their genes to the next generation.
Variation refers to the differences in the genetic structure of the individuals of the population, which produces differences in their physical characteristics.
Selection refers to individuals that might inherit genes that give them a higher chance of surviving and passing their genes to the next generations.
Time refers to the fact that for any population to show the effects of evolution. This cannot be observed in one or two generations, for a new species to evolve, many generations are needed.

If the polar bodies are not viable, meaning they will not live, why are they part of the process of meiosis?.
The primary oocyte is meiotically divided into the secondary oocyte and polar body during oogenesis, and the polar body then goes through meiosis II to produce two polar bodies. Polar bodies are thought to feed the mature ovum cell, which develops during meiosis II in oogenesis.
A polar body is a byproduct of meiotic oocyte division. It is normally the small cell that apoptoses, and it simply disappears. This depiction, however, does not do the cell justice. Polar bodies function to remove one half of the diploid chromosome set produced by meiotic division in the egg, leaving a haploid cell behind. The cell must divide asymmetrically to produce the polar bodies, which is fueled by furrowing (the formation of a trench) near a specific point on the cell membrane.
Three polar bodies are formed during human oogenesis. Polar bodies are tiny cytoplasmic exclusion structures that form after sperm fertilization to contain extra DNA produced during oocyte meiosis. The zygote contains approximately 2-3 polar bodies derived from the oocyte.
The smaller cell is known as the primary polar body, and the larger cell is known as the secondary oocyte.

False is correct answer, most of the energy created from Photosynthesis is stored in the roots for the plant to use in the Spring
What is Photosynthesis?
Photosynthesis is defined as the processes that bring about the manufacturing of food by green plants.
Food is complex energy-rich organic matter which living organisms feed on to obtain nutrients, substances necessary for life. Green plants which are known as autotrophs has the ability to produce their own food through the process of photosynthesis.
The main features of photosynthesis include:
It takes place in the chloroplasts of plants, in the presence of sunlight.
The energy needed for the process is gotten from sunlight which is absorbed by chlorophyll found in the chloroplasts.
The raw materials used are low-energy containing inorganic compounds, example: carbon dioxide and water.
The final products are high-energy containing sugars. oxygen is given off as a waste product.
Plants produce food by turning light energy into chemical energy through a process known as photosynthesis. They store their food as starch. The food is produced in the plant's leaves and must be delivered to other areas of the plant for growth. Phloem, a conducting tissue, aids in the delivery of food to different plant sections. Plants store food for future use.

how is leaves change color related to photosynthesis
Answer:
Explanation:
Chlorophyll Breaks Down
But in the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.
Answer: Chlorophyll
Explanation:
Photosynthesis takes place because the cells of the leaf contain the pigment chlorophyll, a bright-green pigment that gives leaves their green color. As fall approaches, trees seal off leaves from the rest of the plant in order to prevent water loss from stomata. Once the leaves are sealed off, the leaf stops producing chlorophyll. Additionally, any chlorophyll remaining in the leaves begins to break down. As the chlorophyll degrades in the leaves, the bright green color disappears. With the green pigment gone, the colors of the other pigments within the leaf can finally be seen.
In other words, those beautiful oranges and yellows that we associate with fall leaves are actually present in the leaves all along—they have just been masked by the green chlorophyll. With the chlorophyll gone, their true colors can be seen.

An 85. 00 g sample of an unknown compound contains 24. 26 g molybdenum, 24. 33 g sulfur, and the rest is oxygen. What quantity in moles of sulfur are present in the compound?.
The compound contains 0.7589 moles of sulfur.
For all the mole problems you have to,
Divide the molar mass of the element by the number of grams of the element in the compound.
Grams of the element in compound - 24.33 g sulfur
Molar mass of the Sulfur - 32.06 g/mol
Therefore moles present in the compound = Grams of the element in compound / Molar mass of the Sulfur
= 24.33 g S / 32.06 g/mol
= 0.7589 mol S
Hence, 0.7589 moles of sulfur are present in the compound.
In chemistry, the word "mole" refers to a very high number of molecules, atoms, or other particles and is a measuring unit. The amount of units in a mole is 6.02214 x [tex]10^{23}[/tex], often known as Avogadro's Number. These figures are crucial in letting us know how many different components there are.
