Which statement is true according to the kinetic theory?

Convert the volume of CO2 you measured in the glucose reaction to moles of CO2 using the Ideal Gas Law to solve for n. Assume P

olganol [36]

The assumption in this problem is that the gas, CO2, is ideal and that the ideal gas law is applicable such that,
n = PV/RT
We simply substitute the given values to the equation above,
n = (1 atm)(V) / (0.082 Latm/mol.K)(T)
n = 12.20 V/T

The cardiovascular system of a mouse works like that of a human. a mouse is moved from sea level (low altitude) to the top of a

Angelina_Jolie [31]

Answer: Increase the depth of ventilation.

In high altitude, the oxygen pressure will be much lower that makes the gas exchange rate is lower and decrease the oxygen delivery to <span>the tissue.</span> To counter this, the mouse will increase its depth of ventilation so there is more air inside the lungs for every inspiration.

The half-life of carbon-14 is 5730 years. Radiocarbon dating can not be used to estimate the age of objects up to about 50,000 o

Nataly [62]

Answer:

False

Explanation:

it can be used to date stuff up to about 50000 years, so i'd say that its halfly false, so false is correct :)

A segment of a DNA molecule has the base sequence ATGAAC. Write a shorthand structure for this segment and for its complementary

Zanzabum

Answer: See attached picture.

Explanation:

DNA or deoxyribonucleic acid is the name for the molecule that contains the genetic information in all living things. This molecule consists of two strands that wind around each other to form a double helix structure.

The basic unit of nucleic acids are called nucleotides, which are organic molecules formed by the covalent bonding of a nucleoside (a pentose which is a type of sugar and a nitrogenous base) and a phosphate group. So each nucleotide is made up of a pentose sugar called deoxyribose, a nitrogenous base which can be adenine (A), thymine (T), cytosine (C) or guanine (G) and a phosphate group.

<u>What distinguishes one polynucleotide from another is the nitrogenous base</u>, and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information, following the following criterion of complementarity: A-T and G-C. So the sequence of these bases along the chain is what encodes the instructions for forming proteins and RNA molecules. In living organisms, DNA occurs as a double strand of nucleotides, in which the two strands are linked together by connections called hydrogen bridges.

The chemical convention of naming the carbon atoms in the pentose nucleotide pentose numerically confers the names 5' end and 3' end ("five prime end" and "three prime end" respectively). The 5'-end designates the end of a DNA strand that coincides with the phosphate group of the fifth carbon of the respective terminal deoxyribose. A phosphate group attached to the 5'-end allows the ligation of two nucleotides; for example, the covalent bonding of the 5'-phosphate group to the 3'-hydroxyl group of another nucleotide, to form a phosphodiester bond.
