Why are phase changes considered physical and not chemical
changes?

Answers

Answer 1

Answer:

Phase changes are physical changes that take place when matter changes energy states, but chemical bonds are not broken or formed. ... The phase of a substance depends on the amount of energy the atoms contain. All atoms are in motion. The higher the temperature of an atom, the faster the motion

Answer 2
Because it physically change like humans and animals duuh

Answer:

If an organism has a beneficial trait, they have a higher chance of survival, and if they can survive they can reproduce too.

Example: Speckled moths camouflage with the bark of trees and are not easily seen by predators. Black moths do not camouflage with the bark of trees and are easily seen by predators, therefore the black moths are eaten. Because the black moths have been eaten they cannot reproduce and pass on the trait for black wings to their offspring, but the speckled moths are able to reproduce because they survived and are able to pass on the speckled wing trait to their offspring.

? what is the problem i don't see anything

Explanation:

Which of the following data would support the claim that the gravitational force
between objects depends on mass?
O An object's weight can change depending where it is on Earth.
O A rocket can escape Earth's gravity by traveling at high speed.
O The further a planet is away from the sun, the smaller the gravitational force.
O Gravitational force is stronger on more massive planets.

Answers

Answer:

D.

Explanation:

gravitational force of attraction is stronger on more massive planets such as Jupiter

Gravitational force is stronger on more massive planets, the claim that the gravitational force between objects depends on mass, hence option D is correct.

What is gravitational force?

The force that pulls things toward the center of a planet or other body is called gravity. All the planets are kept in orbit around the solar by gravity.

Earth is subject to the same gravity pull that you are. But your force doesn't really affect our globe because Earth is so much larger than you are.

In our world, gravity the moon is maintained in its circle around Earth by gravity, as are the planets in their orbits around the sun. The gravitational force is equivalent to your weight when you are at rest on or near the Earth's surface.

Therefore, gravitational force is stronger on more massive planets, hence option D is correct.

If all of the moths had been completely identical, could they have evolved?

Answers

Answer: i would say no

Explanation:

Answer:

Depends on the Genes

Explanation:

If all of the moths carry one dominant gene and one recessive gene then it is possible this is due to the fact that if each parent has a recessive gene it can appear a 1/4 chance in their offspring causing a change or evolution of the moths. This idea that recessive genes can sometimes be the key of survival in a species such as snow foxes being white even though white hiar is a recessive trait.

Does DNA undergoes translation to produce proteins . RNA undergoes mutation to produce cell walls

Answers

Answer:

No

2. Yes

Explanation:

This is because DNA undergo transcription to produce RNA and RNA undergo translation to produce protein. Translation is the process where mRNA molecule is used as a template to produce protein.

RNA undergo mutation more than DNA and this is because the enzymes found in RNA viruses and participate in copying viral genomes is why it occur so. These enzymes does not have the abilities to recognize DNA damage that enzymes in most organisms have.

Michael planted a tomato plant that produces very juicy tomatoes. When the
tomatoes began to ripen, Michael picked a tomato to eat in a salad. Michael ate the
salad with the tomato at lunch. Later that afternoon, he ran 2 miles during PE and was
sweating at the finish line. How many total energy transformations does this scenario
demonstrate?
1 (potential to kinetic)
2 (chemical to potential,
potential to thermal)
3 (solar to chemical, chemical
to kinetic, kinetic to thermal)
4(chemical to potential
potential to kinetic, kinetic to
nuclear, nuclear to thermal)

Answers

Answer:

3 (solar to chemical, chemical to kinetic, kinetic to thermal)

Explanation:

Michael ate a salad. The salad which he consumes becomes chemical energy, but the tomato he put in his salad has used solar energy, which is simply energy from the sun. The kinetic energy is when he runs 2 miles as kinetic energy is the energy gained from movement. When he stops running, he sweats, which means he is losing heat from his body, therefore the kinetic energy store transfers to the thermal (internal) energy store.

A siamese cat can be one of three colors. Black(B) , Orange (O) or black and orange(BO).
What will be the result of crossing a purebred orange siamese cat with a hybrid (BO)?
Offspring Genotypes
Offspring phenotypes?
What type of inheritance is this?

Answers

Answer:

Offspring Genotypes - ½ BO : ½ OO

Offspring phenotype - ½ Black orange cat : ½ orange cat

Type of inheritance - Co-dominance

Explanation:

This question involves a single gene coding for skin color in Siamese cat. The alleles for orange color (O) and black color (B) are co-dominant i.e. they are both expressed in a heterozygous state.

According to the question, a purebred orange siamese cat (OO) was crossed with a hybrid cat (BO). The following gametes will be produced by each parent:

OO - O only

BO - B and O

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced from this cross:

½ BO : ½ OO

½BO - Black orange phenotype

½OO - Orange phenotype

- This type of inheritance is CO-DOMINANCE
