Answer:
Phase of the cell cycle in which cells grow, duplicate organelles, and synthesize DNA.
S phase
Explanation:
DNA replication occurs in synthesis or in the S phase of the cell cycle. Each chromosome is copied with high fidelity in a process that involves a large number of enzymes. In this process the double strand of DNA breaks down and each individual strand is used as a template for the production of the complementary one. The result is the production of two identical copies of the genetic material.
<span>A flashlight is to battery as your body is to: FOOD.</span>
Answer:
Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Food is chemical energy stored in organic molecules. Food provides both the energy to do work and the carbon to build bodies. Because most autotrophs transform sunlight to make food, we call the process they use photosynthesis.

Answer:
1) pollen grain (A), stigma (B), pollen tube (C), Ovary (D)
The pollen grain is a male reproductive part while ovary is the female reproductive part.
2) When a pollen grain lands on the stigma of a flower, a pollen tube begins to grow. It grows through the style until it reaches an ovule inside the ovary.
3) The pollen tube is a tube that transports the male gamete cells from the pollen grains to the ovule (female gamete) inside the ovary.
The nucleus of the pollen passes along the pollen tube and fuses with the nucleus of the ovule. This process is called fertilisation.
4) After the fertilisation, female parts of the flower develop into fruit and ovules become seeds.
