Stars in the sky appear to be moving. We call this conclusion that is based on observations, clues, or evidence is Inference.

What is inference?

An inference is a conclusion that we can make when we have seen evidences of some particular situations and according to that we give statements.

For example-

1. If someone made a bad face just after taking a bite of food then we can infer that the person didn't like the food.

2. If someone is going away from a place after another person arrived then we can infer that the first person doesn't like the second person.

3. If someone is very lazy from the beginning of the day then we can infer that the person didn't take proper rest.

According to unit conversion, the values from smallest to largest are 10 cm, 1m,10,000mm,0.1 km.

What is unit conversion?

Unit conversion is defined as a multi-step process which involves multiplication or a division operation by a numerical factor.The process of unit conversion requires selection of appropriate number of significant figures and the rounding off procedure.

It involves a conversion factor which is an expression for expressing the relationship between the two units.A conversion ratio always has value which equals to one which indicates that numerator and denominator have values which are expressed in different units.

It is an easy process which involves unit conversion between the different conversion systems. While unit conversion care needs to be taken regarding accuracy and precision.

As 0.1 km=100 m, 10 cm=0.1 m,10,000 mm=10 m and 1 m. Therefore the values from smallest to largest are 10 cm, 1 m,10,000 mm,0.1 km.

Scientists often repeat experiments multiple times.
Why is this important?

B.
Repeating an experiment turns a hypothesis into a theory.
C.
Repeating an experiment gives scientists something to do while they think of new hypotheses.
D.
Repeating an experiment allows scientists to test different variables.

Answers

Answer:

The answer is A.

Explanation:

Scientists repeat the same experiments because they wanna try to see if they keep getting the same result. When a scientific investigation is repeated, this is called replication. Replication is important in science so scientists can “check their work.” The result of an experiment is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.

The noble gases are unreactive and stable. Which of the following explains why this is true?
They have 8 electrons in their outer shell (except for Helium).
They exist on their own without other elements.
They have more electrons than other elements.
They each have no electrons.

EXPLAIN

Answers

Answer:

The answer is A. They have 8 electrons in their outer shell (except for Helium).

Explanation: This is because of the number of valence electrons( the amount of electrons in their outer shell). For a reaction to take place, a transfer of electrons must take place. If their outer shell is already full, they don't have any tendencies to react.

Noble gases are unreactive gases and are stable. This is because they have complete octet or eight electrons in their outer shells. Thus, option A is accurate.

What are noble gases?

Noble gases are the gases of the periodic table that do not show any reaction with other elements and have great stability and low reaction rates.

They are special as their outermost orbit is completely filled to complete their octet rule so they lack any free electron to take part in a chemical reaction.

Therefore, option A. noble gases have eight electrons in their outermost shell.

Various tissues of similar functions  will join together to form organs. There are number of organs each is having specific functions. Heart, lungs, liver etc have more specific functions and they are all made of tissues.

Various metabolic activities in our body is carried by specific organ systems. Thus the fourth level cellular organization is organ system formed by a group of organs joining to perform one or more functions.

There are different organ systems in our body such as respiratory system, digestive system, circulatory system, excretory system etc. These organs systems buildup our body and plays all the functions.
