<h2>Resistance to antibiotics </h2>

Explanation:

Bacteria are single-celled organisms usually found all over the inside and outside of our bodies

Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic
Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections,the bacteria survive and continue to multiply causing more harm
There are two main ways that bacterial cells can acquire antibiotic resistance,one is through mutations that occur in the DNA of the cell during replication and the other way that bacteria acquire resistance is through horizontal gene transfer
Through the process of replication bacteria develop mutations that make them resistant to antibiotics
Bacteria with the resistant mutation have a better chance of survival against antibiotics
Resistant bacteria continue to multiply even when exposed to antibiotics
In horizontal gene transfer,antibiotic resistant genetic material is transferred between different bacterial cells which can happen in three different ways: transformation,transduction or conjugation

Answer:

13 - D

14 - D

15 - C

Explanation:

for 13

A molecule is two or more atoms chemically combined

An example would be carbon dioxide which contains the two atoms, carbon and oxygen

Reasons its not the other answers:

Electrons, Protons and Neutrons are all parts of an atom therefore they cannot be classified as molecules.

For 14

Remember an atom is the most basic unit out of the units we are talking about

The answer would be D

Reasons its not the other answers

Water is considered to be a molecules as it contains two or more atoms (hydrogen and oxygen)

Air is considered to be a mixture as it contains oxygen and nitrogen which can be separated

Salt is considered to be a compound because salt is made up of two atoms (chloride and sodium) in which they are held up by an ionic bond

For 15

The answer would be C (III only)

Carbon hydrogen and oxygen all happen to by atoms

Reasons its not other answer choices:

Like stated previously water is considered to be a molecule therefore we can eliminate the other answer choices

Other notes:

Compounds and molecules both are combinations of two or more atoms however they are not to be mixed together

the main difference between compounds and molecules is how they are held together

Compounds are held together by ionic bonds while molecules are help up by covalent bonds

compounds and molecules are made up of atoms that cannot be separated

Mixtures - A mix of two or more substances that can be separated

Describe how climate would be influenced if:

madam [21]

The rate of energy coming from the Sun changes slightly day to day. .It has been suggested that changes in solar output might affect our climate—both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes.
The axial tilt angle affects climate largely by determining which parts of the earth get more sunlight during different stages of the year Likewise, during winter for the northern hemisphere, there would be fewer hours of daylight because the northern hemisphere would essentially be pointed away from the sun.
If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause the global temperature to decrease drastically.
The Sun's irradiance has its greatest effect on Earth's upper atmosphere, while the lower atmosphere insulates Earth from the increased heat. If the Sun were driving Earth's warming, one would expect to see that upper atmosphere getting increasingly hot.\
have a nice day sorry if wrong T_T
