Heat can be transferred from one place to another by convection. Liquids and gases are fluids because they can be made to flow.

Hot air rising, cooling, and falling is an example of …

During photosynthesis, “producers” like green plants, algae, and some bacteria convert light energy from the sun into chemical energy. Photosynthesis produces chemical energy in the form of glucose, a carbohydrate or sugar. The glucose produced by photosynthesis is an integral part of the food chain because a great deal of energy is stored in the chemical bonds in the glucose molecule, and this energy can be released during digestion and chemical processing by other organisms.

Which form of energy does a plant store when light is transformed during photosynthesis?

An object at rest will _______ if no outside forces are applied.

Traits are inherited through genes, the memory banks of the cell. Every gene has two versions, called alleles. We use capital letters for dominant alleles (A) and lowercase for recessive alleles (a).

Read the scenario and the question.

In fruit flies, red eyes are dominant (A). White eyes are recessive (a).
If the female fly has white eyes and the male fly has homozygous dominant red eyes, what is the probability of offspring having red eyes?

Look at this Punnett square and answer the question.

True or False:

A parent with 0 blood with two 0 genes and a parent with B blood with two B genes will have a B blood type child.

Read the text and answer the question.

“Organisms can be homozygous or heterozygous for a gene. Homozygous means that the organism has two copies of the same allele for a gene.

An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. 

Heterozygous means that an organism has two different alleles of a gene.”

If the two alleles for one trait are the same (pp or PP), the person is  ….      for that trait.

What are the types of high clouds?

Hydrogen gas (H₂) is a molecule, but not a compound because it is made of only one element.

A producer uses energy from the Sun to make food. Which of these is NOT a producer?
