Find the density of an object that has a mass of 22.3g and a volume of 136.7cm3.
Answer:
[tex]0.1631309437 g/cm^3[/tex]
Explanation:
The formula for density is ρ[tex]=\frac{m}{V}[/tex] (where [tex]m[/tex] represents mass, and [tex]V[/tex] represents volume).
With this formula, we can calculate the density of the object:
ρ [tex]= \frac{22.3g}{136.7cm^3}[/tex]
[tex]=0.1631309437 g/cm^3[/tex]

which type of bacteria would most likely be killed when it comes in contact with an antibiotic?
-3 pore bacterial cell
-5 pore bacterial cell
-7 pore bacterial cell
-9 pore bacterial cell
Answer:
B

5. What is a mixture?
6. What is a homogeneous solution? What is another name for this? What is the other type of solution? Find and example of both and be prepared to talk about it in class.
7. What is a solvent? What is a solute? What is the difference between the two?
8. What are substances that release hydrogen ions called? What about more hydroxide ions?
9. What is the measure of H+ in a solution called? What is the value for water? What numbers are acidic and which ones are basic? You live in a one story house made entirely of redwood. What color would the stairs be?
Answer:
8. An Acid and a Base.
7. A solvent is a substance that dissolves a solute, resulting in a solution (able to dissolve other substances). A solute is the dissolved matter in a solution. The key difference between solvent and solute is that the solute is the one to be dissolved while, the solvent is responsible for dissolving it.
6. Homogeneous solutions are solutions with uniform composition and properties throughout the solution. Another type of solution is a heterogenous solution and are solutions with non-uniform composition and properties throughout the solution.
5. A mixture is composed of two or more substance, but they are not chemically combined.
Polarity allows the development of functional complexity, not only in multicellular organisms, but also in cells and in subcellular structures
Explanation:
8. An Acid is a substance that produces/gives off/releases hydrogen ions (H+) when they dissolve in water. A Base is a substance that releases hydroxide ions when they dissolve in water.

The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials.
The fact that both these mammals incubate their immature offspring in a pouch provides evidence that they -
O are descended from a common ancestor
O belong to the same species
O must range great distances to eat
have very similar skeletal structures
Answer:
Belong to the same species
Explanation:
Marsupials carry their young in "pouches", and are therefore related to other marsupials, like the kangaroo, opossum, wombats, and koala to name a few.
The opossum is a native of North America as the kangaroo is a native to Australia and both of them are mammals thus boh belong to the same specie. Thus option B is correct.
What are mammals?A mammal is an animal that is warm-blooded and has hair, vertebrates, and backbone. These creatures share human relations and produce milk for their young ones. The kangaroo is like an opossum that is marsupials carry their young in "pouches".

Use the chart above to determine which substitution mutation has the potential to cause more damage? Highlight your answer. (2pts) a. Substitution of 3rd N-base to go from CAU to CAC b. Substitution of 3rd N-base to go from UGU to UGC c. Substitution of 3rd N-base to go from UCU to UUU 3. Explain WHY: (3pts)_________________________________________
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the chart referred to in the question. However, what appears to be the case is that the three nitrogenous bases represent codons (and the missing chart is the codon chart). The mutation that has the potential to cause more damage will be the one that would change the amino acid formed from the codon change.
A. CAU to CAC: The codons CAU and CAC both form the amino acid histidine and thus is not expected to cause a major damage.
B. UGU to UGC: The codons UGU and UGC both form the amino acid cysteine and thus is not expected to cause a major damage.
C. UCU to UUU: Codon UCU forms the amino acid serine while the codon UUU forms the amino acid phenylalanine. Thus, this eventual change in the amino acid formed has the potential to cause a major damage and thus option C is the correct option.
NOTE that a codon is a sequence of three DNA/RNA nucleotides that corresponds to a single amino acid.

A cart accelerates at 2 m/s2 when a force of 60 N is applied. What is the mass of the cart? (Formula: F=ma)
0.03 kg
30 kg
62 kg
120 kg
Answer:
30 kg
Explanation:
Since a force of 60 N is applied, the mass of this cart is equal to 30 kg.
Given the following data:
Acceleration = 2 [tex]m/s^2[/tex]
Force = 60 Newton.
How to calculate the mass of this cart.From Newton's Second Law of Motion, the force exerted on the cart is given by this formula:
[tex]F=ma[/tex]
Where:
F is the force.m is the mass.a is the acceleration.Making mass the subject of formula, we have:
[tex]m=\frac{F}{a}[/tex]
Substituting the given parameters into the formula, we have;
[tex]m=\frac{60}{2}[/tex]
m = 30 kg.
