is the intrusion the youngest rock in the section how do you know?

Answers

Answer:

Explanation:

The fault cuts through all three sedimentary rock layers (A, B, and C) and also the intrusion (D). So the fault must be the youngest feature. The intrusion (D) cuts through the three sedimentary rock layers, so it must be younger than those layers. By the law of superposition, C is the oldest sedimentary rock, B is younger and A is still younger.

Explanation:

Wind is the horizontal movement of air, transporting energy transferred from the earth's surface as sensible and latent heat. Sensible heat is transferred by the processes of conduction and convection. Conduction transfers energy within a substance, and convection transfers energy through the vertical movement of the heated substance. Latent heat is the transfer of energy by transforming the substance itself. As you recall, water has the ability to exist as liquid, gas or solid. The transformation from liquid to gas is called evaporation; the reverse process, from gas to liquid, is called condensation; from liquid to solid is known as solidification (freezing); and from solid to liquid, fusion (melting). Water can also be transformed directly from solid to gas (sublimation), or the reverse, through a process called deposition. We will see these various processes in the formation of clouds.

Clouds are formed when air contains as much water vapor (gas) as it can hold. This is called the saturation point, and it can be reached in two ways. First, moisture accumulates until it reaches the maximum amount the volume of air can hold. The other method reduces the temperature of the moisture filled air, which in turn lowers the amount of moisture it can contain. Saturation, therefore, is reached through evaporation and condensation, respectively. When saturation occurs, moisture becomes visible water droplets in the form of fog and clouds.

The majority of states give the state legislature main power over the process of drawing congressional and state legislative districts. Thus, option B is correct.

What gerrymandering shaped North Carolina's?

The admittance of Dakota Territory as two states rather than one is a remarkable example. Regardless of its population, each new state carried a minimum of three electoral votes under the standards for representation in the Electoral College.

On February 11, 1812, the first “gerrymander” was sketched on a map and made official. The redistricting plan was approved by Elbridge Gerry, the governor of Massachusetts at the time, in order to maintain his party's hold on power in the forthcoming election.

Therefore, gerrymandering  shape of North Carolina's Twelfth Congressional District.

How does a Covalent Bond Form? ( No goo.gle ik the goo.gle answer cause i tryed looking it up if you put tht answer u wont get brainliest)

Answers

Answer:

A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions. Shared electrons located in the space between the two nuclei are called bonding electrons. The bonded pair is the “glue” that holds the atoms together in molecular units.

10. If one strand of DNA is
TCAAAGCTGC, what is the
complementary strand of DNA on the
other side?

Answers

Answer:

Explanation:As previously stated, DNA is a macromolecule that's made up of individual subunits called nucleotides. Each nucleotide has three parts:

Brought to you by Sciencing

A deoxyribose sugar.

A phosphate group.

A nitrogenous base.

DNA nucleotides can contain one of four nitrogenous bases. These bases are adenine (A), thymine (T), guanine (G) and cytosine (C).

These nucleotides come together to form long chains known as DNA strands. Two complementary DNA strands bond to each other in what looks like a ladder before winding into the double helix form.

The two strands are held together through hydrogen bonds that form between the nitrogenous bases. Adenine (A) forms bonds with thymine (T) while cytosine (C) forms bonds with guanine (G); A only ever pairs with T, and C only ever pairs with G.

Complementary Definition (Biology)

In biology, specifically in terms of genetics and DNA, complementary means that the polynucleotide strand paired with the second polynucleotide strand has a nitrogenous base sequence that is the reverse complement, or the pair, of the other strand.
