Answer:
What happens to cells that "decide" not to divide? If the decision is to not divide, the cell goes into a quiescent, or nondividing state, called G0 (G zero).

1. a wide variety of factors. heat, climate, weather, natural disasters that lower the population of prey animals, etc
2. well and example is this: it is getting hotter in Antarctica, causing the ice caps to melt. this change would make it harder for prey animals like penguins to find somewhere to live, thus making them easier food for predators. such as killer whales and polar bears.
3. the more trees we cut down to make room for buildings, for instance, causes many animals habitats to dissapear, the animals shortly after
Answer:
Wind.
Explanation:
Gymnosperms are also known as naked plants as their ovules are in the unfertilized state and their seeds do not bear fruits. Gymnosperms are known as seed plants.
Gymnosperms pollen grains are transferred from the pollen cone to the ovule. Their pollen are generally transferred by winds as they are lighter and resistant to water. Sometimes, insects are also responsible for the transfer of pollen grains.
Thus, the correct answer is option (b).
The activation energy needed for the chemical reaction decreased by an Enzyme.
Activation energy is the amount of energy required in a chemical reaction.
Enzymes lowers the activation energy by increasing the rate of reaction.
The energy required for a reaction to start is called activation energy. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
