M = 36.5g


^ degrees sign

Q energy heat in JOULES J

m mass of the sample in GRAMS g

C specific heat in J/g^C

ΔT change in temperature ^C
or final temp- initial temp


Based on the information you've provided, we know the following variables:

ΔT= 3^C

Q = 525 J

C= 4.8 J
g×^C

All we have to do is rearrange the equation to solve for m. This can be accomplished by dividing both sides by C and ΔT to get m by itself like this:

m= Q
ΔT×C


Now, we just plug in the known values:

m= 525 J
3^C×4.8 J
g×^C


m=36.5g

Answer: D. Mutation in coding sequences are more likely to be deleterious to the organism than mutations in noncoding sequences.

Explanation: It was not likely to be that the coding sequences are replicated more often. The only possible explanation is that the mutations in coding is more likely to be deleterious to the organism than mutations because it is in a non coding sequence.

kaheart [24]

Answer:

Metallic bonds

Explanation:

Metallic bonds joins atoms of metals and atoms of alloys together. The copper used in making pennies is a metallic substance so it contains metallic bonds.

  • The formation of this bond type is predicated on the large atomic radius, low ionization energy and large number of electrons in the valence shell.
  • The bond is an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud.
  • The electron cloud is jointly formed by all the atoms by losing their outermost shell electrons.

This way the bond in pennies are metallic in nature.
