Will give extra points for right answer or explanation

Answers

Answer:

The “recommended temperature limit” indicates limit of the temperature that is good for our world.

Explanation:

The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature..

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.

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.

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.
