Which of the following describes the energy transformation that takes place when a boy eats an apple and then lifts weights?1. Chemical energy is converted to mechanical and heat energy.
2.Chemical energy is converted to mechanical energy.
3. Chemical energy is converted to heat energy.
4. Chemical energy is converted to mechanical and kinetic energy.

Answers

the correct answer is 1. Chemical energy is converted to mechanical and heat energy.

When the boy eats apple, the chemical energy of the apple first converted in the heat energy in the process of digestion, which maintains our body temperature, than the body of the boy converts the heat energy into mechanical energy.

Therefore the correct option is 1.

Answer:

Chemical energy is converted to mechanical and heat energy.

In 1956, Herbert FaulknerCopeland (1902-1968) proposed the four kingdom classification.

Monera, Protista, Plantae, and Animalia were the four kingdoms. He classified unicellular organisms into two groups: the Monera kingdom and the Protista kingdom.

The classificationsystem provides a wealth of information about organism characteristics. Using scientific names as a shorthand method of describing a plant or animal can thus be beneficial.

Thus, the correct option is C.

The orientation of which of the following does not influence the phases of the moon?a.
Earth

c.
Sun

b.
the moon

d.
Stars

Answers

So we want to know what is not influencing the phases of the Moon. What influences Moon phases are celestial bodies that are close enough to have enough gravitational force to have an influence. Those celestial bodies would be the Earth and the Sun, since moon itself cant influence itself and all other stars are too far to exert gravitational force. So the correct answer would be the Moon and the stars do NOT have an influence on the Moon phases.

Answer:

So the correct answer would be the stars do NOT have an influence on the Moon phases.
