How do T-cells help with destroying viruses?
Answer:T-cells are a type of white blood cell that work with macrophages. Unlike macrophages that can attack any invading cell or virus, each T-cell can fight only one type of virus. You might think this means macrophages are stronger than T-cells, but they aren’t. Instead, T-cells are like a special forces unit that fights only one kind of virus that might be attacking your body.The T-cell receptor fits with its antigen like a complex key. When the perfectly shaped virus antigen on an infected cell fits into the Killer T-cell receptor, the T-cell releases perforin and cytotoxins. ... Cytotoxins go directly inside the cell through this pore, destroying it and any viruses inside.

Why is it possible that two ecosystems with identical conditions of temperature and precipitation, could support different plants?
Answer:
Because even if they are similar, they still have a difference between them, and that difference helps other plants.
It is possible because plants require other factors like sunlight and soil nutrients) other than Temperature and precipitation to grow
Plants require some Important factors for its growth and development and they are :
Temperature precipitation Sunlight soil nutrients type of soilThe two ecosystems with identical conditions of Temperature and precipitation might have differences in the amount of sunlight they receive and the Nutrients contained in its soil. therefore the ecosystems although similar can support different plants based on the difference in the amount of sunlight and Nutrients contained in the soil.

what stores and delivers nutrients throughout the cell and transports waste to the cell membrane
[tex] \huge \sf \star{Answer} \star[/tex]
Vacuoles store water, food, and waste. The endoplasmic reticulum (ER) is a series of tunnels throughout the cytoplasm. They transport proteins from one part of the cell to another. Ribosomes are the protein factories of the cell.
Hope it helps uh...The organelle that is responsible for storing and transporting nutrients through the cells is Vacuoles.
Vacuoles are also know as storage containers, they act as a storage organ in the body. This storage organ helps to transport food substances /molecules in the cell. Vacuoles are composed of enzymes, they help to hold water an food molecules. Vacuoles also help to remove waste substances that are harmful to the body.
The vacuole helps to keep balance in the body as they help to keep useful molecules and also get rid of waste substances.

First question: When the population of lynx increases, the population of hares will decrease due to being over-hunted by more predators than usual. The hare is a source of food to the lynx, so with more lynx's...less hares... and less hares means either less food for the lynx and their population starts to die off...OR... The lynx adapt and start hunting new animals which could cause a massive disruption in the food chain.
Second question: When the number of hares increase in the environment it would mean more food for the lynx and other predatory animals. But with more food, comes more overpopulation. with plenty to eat the lynx population increases and that could cause problems for the environment, and other creatures.

• sexual reproduction
• diploid
• unique daughter cells
• gametes
• meiosis
• unique
• haploid
• zygote
• identical daughter cells
• mitosis
Answer:
Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.
Cells produced in sexual reproduction will have half of the genetic information of body cells and will be genetically unique. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a zygote: the first body of a new individual.
The new individual will now have cells that are diploid, meaning they have two sets of chromosomes. They zygote will have to do a lot of mitosis allowing it to grow quickly and ensure that all of its cells are genetically unique.
How does the position of Earth and its orbit affect climate change?
Answer:
The Earth's orbit around the Sun is an ellipse, but it does change shape. ... At other times, the ellipse is more pronounced so that the Earth moves closer and further away from the Sun as it orbits. When the Earth is closer to the Sun our climate is warmer and this cycle also affects the length of the seasons.
