Why do atoms form bonds with each other
Answer:
Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.

How does an enzyme influence a chemical reaction
A. It provides the substrate needed for the reaction to occur
B. It raises the activation energy so that a reaction can occur
C. It speeds up the reaction rate
D. It is used as a reactant to form the product
Answer:
It speeds up the reaction rate
Explanation:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Enzyme actually raises the reaction rate to make the product sooner than before by lowering the activation energy, the correct option is C.
What are enzymes?An enzyme is a compound that acts as a catalyst in life forms, regulating the rate at which chemical reactions occur while remaining unaffected.
Substrates are molecules on which enzymes can act, and the enzyme converts the substrates into distinct molecules known as products.
While working in any chemical reaction, enzyme usually lowers the activation energy, means the minimum energy required to complete the transformation of reactant into products, so that the reaction will get speed up.
Thus, the correct option is C.

Which change to one of the kits would make it useful for modeling proteins? a.Set 1, add a box for phosphorous (P) atoms. b.Set 2, add a box for sulfur (S) atoms c.Set 3, replace the box of phosphorous (P) atoms with a box of sulfur (S) atoms d.Set 4, replace the box of oxygen (O) atoms with a box of nitrogen atoms (N)
Answer:
The correct answer is - option C.
Explanation:
Proteins are made up of long chains of polypeptide chains made up of amino acids contain the basic elements of organic matter carbon, oxygen, and hydrogen with the addition of nitrogen.
In the given option set 1, and set 2 lacks the nitrogen elements whereas in set 4 the oxygen is not available, and set 3 have all the elements required for the protein.
Thus, the correct answer is - option C.
Answer:
set 3

On a hot summer day, Tameka spilled water on the sidewalk, but a few hours later there was no evidence of the water. What most likely happened to the water?
A) boiling and evaporation
B) sublimation and vaporization
C) boiling and sublimation
D) vaporization and evaporation
Answer:
d
Explanation:
because the sun dried up the water which is making it get so hot it just evaporates into a gas
D
Vaporization is the transitional phase of an element as it changes from a liquid phase into a gas phase at a point greater than the boiling point. Evaporation is the transition from the liquid phase to the gas phase that takes place below the boiling temperature.
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other.
They BOTH turn into GAS

12. Suppose you took a strong antibiotic to treat lyme disease. You then started have
problems with your digestive system. How are these two related?
13. You have pneumonia caused by a virus. What remedy would the doctor prescribe
and why?
Explanation:
11: If it grows, you do not have a problem so don't fertilize. If you have problems growing a lot of different plants, it may be a nutrient issue. ... Adding a bit of compost, or manure from time to time is a good idea – not for the nutrients, but the organic matter will improve soil health.
12:Since Lyme disease is a systemic infection, the bacteria can affect any organ or tissue in the body. The bacteria that cause Lyme disease and its associated infections can directly damage the digestive tract and can create immune-mediated inflammation that causes gastrointestinal symptoms or disorders.
13:If a virus is causing your pneumonia, antibiotics won't help. Your doctor may give you an antiviral medication. If you have an influenza virus, your doctor may prescribe medications such as oseltamivir (Tamiflu), zanamivir (Relenza), or peramivir (Rapivab).

1 g/cm³
Explanation:Hi there !
density formula
d = m/V
volume formula
V = l×w×h
replace
d = 8g/2cm×4cm×1cm
= 8g/8cm³

In the early 19th century, rabbits were shipped from Europe to Australia. These non-native rabbits rapidly became invasive due to little competition for food and relatively few predators in the introduced regions. Which of the following explains the effect humans most likely had on the ecosystem by introducing this non-native rabbit species?
Answer:
decrease in population of the prey and an increase in rabbit population
Explanation:
The prey were constantly being killed and eaten by rabbits so there was a decrease in their population whilst the rabbits had an increase in their population due to there being more food for the to live on and there being less competition.

Is the space between the particles slay the same when thermal energy is added to the material?
Answer:
No
Explanation:
When thermal energy is added to a material ,kinetic energy increases causing the molecules to begin to move faster. When these particles move faster, more space is created because there is more energy to overcome the intermolecular forces, which causes the distance of the molecules to increase. This is why a liquid can become a gas (evaporation) the increase in thermal energy increases the movement of the molecules and they overcome the forces that hold them together, causing the distance between each particles
