The other half receives 20% less food than a typical mouse eats each day. The day of death (lifespan) is recorded for all mice. All mice live in the same room, in the same type of cage, with access to water. A. amount of food available B. volume of water available C. genetically ideantical mice D. happiness of each mice E. lifespan of each mice

Answer:

A. amount of food available

Explanation:

An experiment consists of two types of variables, independent and dependent. Value of independent variable is decided by the person doing the experiment and is independent of experimental conditions. Value of dependent variable is dependent on the independent variable. It can not be altered by the person doing experiment.

Here, it is given that mice receive variable amount of food each day and their lifespan is recorded. Since the amount of food is decided already it is the independent variable. The lifespan is expected to depend on the amount of food hence it is the dependent variable.

Evolution means change in the physical features of an organism.

Explanation:

Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.

user100 [1]
Before cell reproduction or mitosis can proceed, the correct sequence of steps that must first occur is the following one: growth, chromosome replication, repair of chromosomal errors, and duplication of cell organelles. This is the right order in which these steps should happen before the cell is to reproduce or split itself into several parts during mitosis.
