Explanation:

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.

Answer:

The answer is Water droplets sticking to a window.

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

Recent missions to Mars haven't turned up definite proof of life, but some tantalizing possibilities have been uncovered.

Explanation: Water and ice caps if there's water there's life. but its not entirely true... because there isn't any life on mars... or so NASA says  National Aeronautics and Space Administration more like Never a straight answer.

Many people believed that there was evidence of intelligent life on Mars, because of the similarities of this planet to planet Earth and because there are indications that there was water on Mars.

Although it is currently known that there is no intelligent life on Mars, many researchers believe that this planet has been inhabited in the past.

There is some evidence that allows this speculation to be established. Among this evidence, scientists claim that:

With this, we can see that, according to the evidence, it is not possible to affirm that there was already intelligent life on Mars, but that the planet has the possibility of having been populated by microorganisms.

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]

Answer:

The sun

Explanation:

The sun provides the light energy that plants need in order to produce glucose the animals gain after eating the plants or the animals that ate the plants.

The initial and ultimate source of the energy in all types of food webs and food chains is the Sun.

The Sun is the major source of energy for living organisms and the ecosystems of which they are a part on the Earth. Producers are the organisms of the food chain which produce energy such as plants, algae, and cyanobacteria. These organisms use the energy from sunlight to make organic matter from that of carbon dioxide and water molecules. This establishes the beginning of energy flow through almost all the food webs.

The light which is coming from the sun allows the green plants that is the producers to manufacture chemical energy which fuels all the cellular functions. In turn once the plants are eaten, this chemical energy and nutrients are transferred to the consumers and to other higher organisms.

With respect to one another, galaxies have been found to be moving farther apart from each other. The correct option is 2.

Galaxies are large areas that contain stars, dark matter, dust, interstellar gases, etc. It is a gravity-bound system that contains everything in its own place.

There are many galaxies, some are still undiscovered. Our galaxy in which the earth is present is called the Milky Way. It is called the Milky Way because due to many stars it looks like a shiny white path.

Now, the Big Bang Theory says that the universe is made up of expanding of a single point. And the universe is still expanding, so the galaxies' and other matters still going farther away.

Thus, the correct option is 2. Moving farther apart.

Answer:

A disaccharide is a carbohydrate polymer composed of two sugar monomers (monosaccharides) which are joined by a glycosidic bond formed by a condensation reaction.

Answer:

Explanation:

Disaccharide is a sugar, the prefix Di means 2, the prefix mono means 1, so 2 monosaccharides is 1 disaccharide. Long chains of monosaccharides make polysaccharides(more than 2).

The monomers of proteins are amino acids

The monomers of Carbohydrates are monosaccharides

There are no monomers to Lipids

The monomers of Nucleic acids are nucleotides

The condition is called "Spinal Bifida", caused by lack of vitamin B12 which helps regenerate the active form of folate.

Explanation:

Because Lori is a vegan, her vitamin B12 intake which comes from animal products such as meat, is not enough. She has to take supplements to make up for the lack of it in her diet.

As stated in the question, this lack of vitamin B12 causes her child to have a defect in his spinal cord called Spinal Bifida that defines a spinal cord or spine that has not fully developed. The vitamin B12 is necessary for regenerating the active form of folate.

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.

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.

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.

Answer:

The answer is "Option C".

Explanation:

In the given question, the pH scale is used to evaluate acid or basic (alkalinity) formulas. It is nearly positive throughout the blood. Human blood has to maintain its pH at about 7.4, to prevent dramatically increased or lower changes, even though the bloodstream enters or exits acidic or essential substances.  

Answer:

Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.

Explanation:

Active transports moves against the concentration gradient (hence why it needs energy or ATP to do so, its going "against the grain"). Facilitated diffusion does not require ATP but does something require carrier proteins during passive transport.
