Do galaxies move and if so how do we know?
Answer: Galaxies do move. They both rotate and move through space. But how do we know? Fortunately, there is a way to detect the motion of a galaxy: By examining the spectrum of light from a galaxy, you can determine whether the galaxy is moving towards or away from Earth, and how fast.

NASA has discovered a new planet in a distant solar system. On this new planet, they have found a mysterious green slime. The green slime only grows at certain temperatures and under certain moisture levels. Scientists found that if they put the green slime in a freezer, it would shrink itself to maintain an internal temperature of 75°. They also found that the green slime has specialized pumps to pump out water if it gets too wet. As of yet, none of the green slime samples have reproduced, but they do appear to be growing very slowly. When looking at the green slime under the microscope, scientists can see smaller structures filled with green slime and tiny pumps. What are some reasons the green slime may be considered a living organism? What are some reasons the green slime may not be considered a living organism? Do you think the green slime is alive? Why or why not? *
Answer: The following assumptions can be made for the green slime.
Explanation:
1. The green slime has many characteristics, which indicates that these are adaptations which were used by the slime to survive. It uses pump to expel out excess water, and in freezing it can shrink itself to maintain its temperature. Thus these characteristics indicates that the green slime is living.
2. The green slime did not reproduced. This indicates that the slime was not living.
3. The slime was living because it had characteristics which enable it to survive like other living organisms.

Dr. Kettlewelll predicted that clean forests would have _____________ colored moths, and polluted forests would have _________ colored moths.
Answer:
Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.
Dr. Kettlewall predicted that clean forests would have light-colored moths and polluted forests would have dark-colored moths. This is an example of natural selection.
What is natural selection?Natural selection is a phenomenon in which the fittest individual is chosen by nature. The animal can live and reproduce in that particular environment. An example is the peppered moth population.
The light-colored moths were found on the light-coloured bark, but their population started to decline after the pollution. In the polluted environment, they were easily chosen by predators. So only dark moths survived because they blended in with the polluted environment.
Following the end of the pollution, light colored moth increased again. Predators had a difficult time identifying the light moth because it blended in with the unpolluted environment. Hence, their population increases in unpolluted areas.
Hence, Dr. Kettlewall predicted that a clean forest would have a light-colored moth and a polluted forest would have a dark-colored moth.

What are the solutions of the following equation?
Answer:
Explanation:
5 ( x + 3 ) - 4 = 8 ( x + 3 ) - 4
5x + 15 - 4 = 8x + 24 - 4
5x + 11 = 8x + 20
By substituting,
5x - 8x = 20 - 11
-3x = 9
x = -9 / 3
x = -3
So the correct option is D

Answer:
(A) rate=
Sp

Explanation:
The rate of chemical is a measure of the speed of a chemical reaction.
The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
Reaction rate is usually expressed in terms of a change in concentration of the chosen reactant or product per unit of time.
During a reaction, the concentration of the reactant decreases exponentially with time while that of a product increases exponentially with time.
Reaction rate = [tex]\frac{change in concentration of a reactant/product}{Time taken}[/tex]

Explanation:
An element only has one type of atom and cannot be broken down by chemical means.
Let's analyze the answer choices.
1. This has two types of atoms, so it cannot be an element. It has more than one type of atom.
2. This has two types of atoms that are bonded together. It cannot be an element because there is more than one type of atom and the bonds can be broken.
3. This has one type of atoms, so it is an element.
Therefore the best answer choice is 3.

A certain chocolate bar contains 6 mg of caffeine in a 1.5 oz. Serving. The king-size version of the chocolate bar is 85 grams. How much caffeine, in mg, would you consume if you eat the entire king-size bar?Fill in the answer in the blank provided. Mg of caffeine
Answer:
The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg
Explanation:
This question can be reframed in the manner below for better understanding.
If 1.5 oz or ounce of a chocolate bar contains 6 mg of caffeine, how many milligrams (mg) of caffeine is contained in 85 grams of the same chocolate bar.
Firstly, the ounce should be converted to grams
If 1 ounce = 28.35g
1.5 ounce = ?
= 1.5 × 28.35/1
=42.53g
Hence, 42.53g of the chocolate bar contains 6 mg of caffeine
85g of the chocolate will contain
42.53g = 6mg
85g = X
where X is the amount of caffeine that will be consumed in mg
X = 85 × 6/42.53
X = 11.99 mg
The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg

producing offspring
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Reproduction always involves changes in inherited characteristics, whereas heredity
does not
Heredity always involves changes in inherited characteristics, whereas reproduction
does not
Answer:
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Explanation:
PLEASE MARK BRAINLIEST, if you think this is correct and best! Thanks!
Reproduction generally means making copy of something, like giving birth/breeding, duplicating.
Heredity is inheritance of traits/ passing on traits from parents t thsir child/children through genes. It makes children have same traits as their parents and looks so what same like their parents!
They definitely aren’t same!
Reproduction is the process of producing offspring, whereas heredity is the process of passing on traits.
What do you mean by heredity?Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information.
Heredity explains why offspring resemble, but are not identical to, their parents and is a unifying biological principle. Heredity refers to specific mechanisms by which characteristics or traits are passed from one generation to the next via genes.
Heredity can be defined as the transfer of genetic characters from parents to offsprings by the process of fertilization, where the nuclei of male and female gamete fuses with each other and forms the genetic material of the zygote.

Which best describes a neutralization reaction? areaction between an acid and a base Oareaction between two acids O a reaction between a base and a salt Oa reaction between two salts
The statement best describes a neutralization reaction is a reaction between an acid and a base. The correct option is a.
What is neutralization?Neutralization is the reaction that occurs when acids and bases of equal strength react to generate salt and water. Because acid and bases cancel each other out, the salt generated in the reaction is neutral.
Neutralization is the reaction of an acid and a base that causes the pH to rise to 7. It is a useful process that occurs in everyday life, such as the treatment of acid indigestion and the addition of lime to acidic soil. Neutralization lowers the pH of alkali to around seven.
Taking a base helps to neutralize excess acid in our stomach. Because formic acid is present in the ant sting, it can be painful. Using moist baking soda, which is basic in nature, we can neutralize the acid action and reduce the discomfort caused by the sting.
Therefore, the correct option is a, action between an acid and a base.
