Which of the following best describes the movement of an object at rest if no outside forces act on it? (1 point)It will move due to inertia.
Gravity will eventually cause it to move.
It will stay at rest due to inertia.
It will stay at rest due to gravity

Answers

Answer 1
Answer:

Answer;

It will stay at rest due to inertia.

Explanation;

According to Newton's first law, an object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.

The law of motion states that there must be a cause; which is a net external force;for there to be any change in velocity, either a change in magnitude or direction.

Inertia of Rest is the tendency of an object (or body) to continue its state of rest unless it is acted upon by an external force.

Answer 2
Answer: The option which best describes the movement of an object at rest if no outside forces act on it is that it will stay at rest due to inertia.

How can this research be improved so that she will have greater confidence in her data?

What is the slope of the line that passes through the points (-2,5) and (1,4)?

Answers

Hello!

Explanation:

Slope: (Y^2-Y^1)/(X^2-X^1)=(rise)/(run)

(4-5=-1)/(1-(-2)=1+2=3)=(-1)/(3)=-(1)/(3)

Slope is -1/3

Answer is -1/3

Hope this helps!

Gram-negative bacteria have a cell wall that is and does not accept the stain, making it appear .

Answers

Gram-negative bacteria have a cell wall that is thin and does not accept the stain, making it appear red or pink.

Gram staining is used for differentiation gram-positive from gram-negative bacteria based on the characteristic of their cell wall. Gram-negative bacteria have a thinner cell wall than gram-positive bacteria. In this staining, bacteria are first stained with crystal violet dye. Only gram-positive bacteria will be violet colored because they can retain the dye thanks to their cell wall. The second staining with fuchsine or safranin will give the red or pink color to the gram-negative bacteria. 

Answer: "thick" "pink"

White spotting, or piebald trait, characterized by an absence of hair pigment in specific places, is caused by mutant copies of a A) carbohydrate. B) gene. C) lipid. D) steroid

Answers

Answer: Gene

Explanation:

Mutation can be defined as the change in the single base pair of the DNA. Each and every trait inside an eukaryotic organism body is controlled by the help of the gene.

Pie bald is also a trait controlled by the genes in the body. Pie bald can be defined as a pattern of unpigmented spots on the pigmented background of scale, feather and hair.

Example: A pie bald black and white dog is a black dog with white spots on it.
B. Gene. Piebalding is caused by mutant copies of genes.

Which is caused when there is a permanent change to the sequence of a gene?mutation
karyotype
mutagen
phenotype

Answers

Mutation is the correct answer.
Mutation is what's caused to the sequence of a gene

What helps keep the temperature of living things

Answers

Water has a rather high specific heat, so it takes quite a bit of energy to raise or lower the temperature of water. therefore, water helps keep the temperature of living things. 

Which of the following statements is true?Weathering and erosion are the same process.
Coarse, infertile soil is usually found near the base of a mountain.
Rocks formed at low temperatures weather more quickly than rocks formed at high temperatures.
Weathering is the movement of sediment from one location to another.

Answers

Correct answer: B). Coarse, infertile soil is usually found near the base of a mountain.

The course, infertile soil is normally found near the base of the mountains. It provides stable bases for the high mountain. It helps to keep the ground firm and it would take a longer time to erode and evolve. These soil are a type of loamy soil. The nature of erosion can affect the composition and structure of these type of soil. Rest all other options are false.

Hence, the correct answer would be option B
the true statement is that coarse, fertile soil is found near the base of a mountain
