Answer:
To show that both are evolved from a common ancestor.
Explanation:
It make the comparison between humans and chimps because the two species are so closely related to each other. Humans an chimps evolved from a single ancestor species about six or seven million years ago. Humans and chimps gradually evolved from a common ancestor due to environmental conditions that change their DNA which passed from generation to generation and bring changes in their shape and appearance as well.
Answer:
B. It will become larger by taking in nutrients.
Explanation:
Growth is a characteristics of every living thing and is portrayed by an increase in size (height and weight) of such organism. This question depicts an image of a unicellular organism called EUGLENA.
Like every other living organism, for Euglena to grow, it must take in nutrients necessary for its growth. Euglena does this by performing photosynthesis or by absorbing it from their immediate environment. As it grows, it takes in nutrients and uses it for growth, which is evident by its increase in size i.e. gets larger.
Answer:
B. increase its ratio of surface area to volume
Explanation:
This causes the cell to reach a "breaking point" at which it can divide into two separate cells.
Natural selection is a process of adaptation by an organism to the changing environment by bringing selective changes to its genotype or genetic composition.
Artificial selection, also called selective breeding, is the process where humans identify desirable traits in animals and plants and use these traits to develop desirable phenotypic traits by breeding.
Some examples of natural selection include the selection of long-necked giraffes and the changes in the size and shape of beaks of birds according to their feeding habits.
Some examples of artificial selection include dog breeding to produce new breeds of dogs and cross-breeding in cash crops like wheat and rice.
The simplest organisms are cells.
A cell is: The smallest structural and functional unit of an organism.
