What is the relationship between mutation, the cell cycle, and cancer? Select all statements that apply.

A. Mutated genes typically allow cells to respond to checkpoint proteins that halt the cell cycle, thus avoiding formation of tumors.

B. As a result of unregulated cell cycles, cells may become cancerous, meaning that the cells grow and divide uncontrollably.

C. Cancerous cells may form malignant tumors that invade and destroy surrounding healthy tissue.

D. Mutated, defective genes may cause cells to become unable to respond to signals that regulate the cell cyle

Sexual reproduction

Answer:

Meiosis is sexual reproduction.

Explanation:

Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).

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.

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 :

The 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.

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.

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.
