Which section of the Venn diagram represents the contents of the nucleus?

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

This refers to the condition, environment and or circumstance under which a speech or communication was made.

Explanation:

The context of a speech can significantly alter their meaning even though the body of the information has not changed. This is why understanding contexts are very crucial.

The context of a speech helps the receiver to make a decision about what to place importance on and about what, he or she can safely make assumptions about.

Some examples of communication contexts are:

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: D

Explanation: community forms an ecosystem by its interaction with the abiotic environment. Species: A group of organisms that can potentially interbreed to produce fertile, viable offspring.

Given:

The solution decreased by [tex]\dfrac{9}{8}[/tex] ounces every hour for 5 hours.

Remaining solution at the end of the experiment = [tex]\dfrac{99}{8}[/tex] ounces.

To find:

The initial amount of solution.

Solution:

Let the initial amount of the solution be x.

The solution decreased by [tex]\dfrac{9}{8}[/tex] ounces every hour for 5 hours.

Total decreased amount  [tex]=\dfrac{9}{8}\times 5[/tex]

                                          [tex]=\dfrac{45}{8}[/tex]

Initial amount = Remining amount + Decreased amount of solution.

[tex]x=\dfrac{99}{8}+\dfrac{45}{8}[/tex]

[tex]x=\dfrac{99+45}{8}[/tex]

[tex]x=\dfrac{144}{8}[/tex]

[tex]x=18[/tex]

Therefore, the initial amount of solution is 18 ounces.

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.

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:

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.

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

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.

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.

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.

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.
