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.

How does natural selection lead to the evolution of a species?
Answer:
One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.

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.
