Complex interactions must occur before solar energy is converted into a form of energy humans need to work and perform many life processes. Choose the sequence that best shows this path of energy.

radiant energy chemical energy mechanical energy

light energy mechanical energy chemical energy

mechanical energy chemical energy radiant energy

mechanical energy radiant energy chemical energy

Why is it necessary to have sunlight in this equation?

The process cannot occur without energy from the Sun.

Sunlight uses carbon dioxide and water to form sugar.

The arrow represents the specific direction of sunlight.

The arrow tells the equation to yield.

Which wavelength of light energy from the sun is LEAST likely to help plants grow?

Green, because it is reflected by the leaf

Green, because it is absorbed by the leaf

Red, because it is absorbed by the leaf

Red, because it is reflected by the leaf

In addition to other materials, both the respiratory system and the circulatory system move oxygen. Which of the following BEST explains why there are two human body systems to move oxygen?

One moves oxygen into the body, and the other moves oxygen through the body.

One moves oxygen into the body, and the other moves oxygen out of the body.

One moves oxygen while awake, and the other moves oxygen when asleep.

One moves oxygen to the upper body, and the other moves oxygen to the lower body.

Common Bermuda grass is found in most parts of Texas. Like most native grasses it is pollinated by the wind. It produces large numbers of very tiny seeds that are carried by the wind. It is a nuisance plant in many yards, spreading along the ground with tough runners and underground stems. It can quickly take over a garden or flower bed. Which of the following is most important for the spread of Bermuda grass throughout Texas?

The grass produces a large number of very tiny seeds.

The grass runners can be used by some birds in their nests.

The grass is pollinated by the wind.

The diagram illustrates cells found in the stomach undergoing mitosis. Which statement about the cells is correct?

Cell A contains exactly the same genetic information as Cell B.

The stomach acid destroyed the genetic information in the parent cell, but left the offspring cells undamaged.

Cells in the stomach lining reproduce slowly due to the damaging effects of stomach acid.

Cell A has different genetic information than Cell B.

Many plants use brightly colored flowers to attract insect pollinators. Which is the MOST likely conclusion about a plant that has very small flowers that are hard to see?

It does not require a pollinator to reproduce.

Compared with the genetic material of the original cell in this diagram, after mitosis each of the two new cells contains :

genetic material that is identical to the parent cell

half the genetic material of the parent cell

twice as much genetic material as the parent cell

new genetic material that is different from that of the parent cell
