Explanation:

Answer:

1. The purpose of an experiment is to test out your hypothesis. If your hypothesis is correct, then it is a theory that could work every single time the experiment has been performed by scientists.

2. Limiting factors include a low food supply and lack of space. Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.

3. An example of a hypothesis based on observation and scientific principles is:

Deaf children whose parents are deaf will acquire language faster than deaf children whose parents are not deaf.

A hypothesis is an informed prediction or a tentative statement about what you think that would occur in a scientific experiment as a result of experience from observations accepted by scientific rules and law.

A hypothesis is a testable statement obtained from the research question but questions cannot be tested directly, it is the proposed relationship between the variables that are tested.

An example of a hypothesis is:

Deaf children whose parents are deaf will acquire language faster than deaf children whose parents are not deaf.

This specifies the direction of the hypothesis because one group is faster than the other.

4. In any ecosystem, organisms and populations with similar requirements for food, water, oxygen or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction. Growth of organisms and population increased are limited by access to resources.

The purpose of an experiment is to test out your hypothesis. If your hypothesis is correct, then it is a theory that could work every single time the experiment has been performed by scientists.Other part of the question is discussed below:

Limiting factors include a low food supply and lack of space. Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.

As per questions,

• Myth: A dead organism is the same as a non-living thing in science.

Fact: A dead organism is not the same as a non-living thing in science.

Evidence: A dead organism means that it was once alive, whereas a non-living thing has never been alive.

• Myth: The Linnaeus system of classification will always stay the same.

Fact: The Linnaeus system of classification will pass on .

Evidence: Its new species are being found. Also, Carl Linnaeus came up with a sequential classification of living organism under different taxons namely Kingdom, phylum, class, order, family, genus and species.

• Myth: Tigers and goldfish are not related.

Fact: Tigers and goldfish are related

Evidence: They fall into the same category of vertebrates, which means that both creatures have spines, and internal bone structure.

• Myth: An organism's kingdom only describes physical characteristics.

Fact: An organism's kingdom not only describes physical characteristics.

Evidence: This is evident by that both plant and animal kingdom are classified on the basis of photosynthetic ability. Besides physical characteristics, it also describes its mode of nutrition and food characteristics.

• Myth: Mammals and plants don't belong in the same domain.

Fact: Mammals and plants belong in the same domain.

Evidence: Plants have cells, nucleus, breathing and respiratory capabilities just like mammals.

Your myth: Animals are not related to humans.

Fact: Animals are indirectly related to humans.

Evidence: Humans possessess some unique features found in other species, hence, we are related to apes. At the known time, chimpanzees is our closest relative, and we share up to 98% of the DNA sequence with them.

Explanation: Hope this helps

Answer:

B

Explanation:

neutrons + atomic number/proton/electron for a neutral atom = mass number

e.g

mass number of Chlorine 35.5

proton number 17

neutron number will be 35.5-17 = 18.5

Therefore.....

your question deduced says

atomic number is 5

mass number is 11

neutron number is however mass number minus atomic number 11-5 =6

Answer:

5

35 divided by 7 = 5

Answer:

C polyatomic ions are made up of more than one atoms. The correct options are,

Explanation:

Polyatomic ions have many charges.  

Polyatomic ions attract other ions to form ionic bonds.  

Polyatomic ions are made up of two or more types of atoms.

Polyatomic ion:

They are also known as a molecular ion, It is an ion composed of two or more covalently bonded atoms.

They have extra or lesser electrons than they need.

They are charged hence they attract opposite one.

For example-

Therefore, C polyatomic ions are made up of more than one atoms.

Answer:

C.

Explanation:

This would be correct because polyatomic ions exist in a group of more than one atom.

Answer:

6 neutrons and 6 electrons

Explanation:

But if wrong just ignore honestly.

Answer: the mass of 3.01 atoms of chlorine is 35.46/2 = 17.73 g.

Explanation: hope its correct

step by step: molar mass: (2 x 35.46) g/mol = 70.92 g/mol

1 mole chlorine = 6.02 x 10^23 molecules of chlorine.

Mass of 6.02 x 10^23 molecules chlorine = 70.92 g

Mass of 3.01 x 10^23 molecules chlorine = 70.92 x(3.01 x 10^23)/(6.02 x 10^23)g

= 35.46 g

Answer:

substance is related to the average kinetic energy of the particles of that substance

Explanation:

Answer:

As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

he required empirical formula based on the data provided is Na2CO3.H2O.

The term empirical formula refers to the formula of a compound which shows the ratio of each specie present.

We have the following;

Mass of sodium = 37.07-g

Mass of carbonate = 48.39 g

Mass of water = 14.54-g

Number of moles of sodium = 37.07-g/23 g/mol = 2 moles

Number of moles of carbonate = 48.39 g/61 g/mol = 1 mole

Number of moles of water = 14.54/18 g/mol = 1 mole

The mole ratio is 2 : 1: 1

Hence, the required empirical formula is Na2CO3.H2O
