A classmate has asked you to help them determine the concentration of DNA in their solution. Their A260 reading was 1.69. What was the concentration of their DNA
Answers
Answer:
Acid , phenol or protein
Explanation:
The ratio of absorbance at 260 and 280nm is what is usually used to assess the purity which a DNA or RNA posses. A ratio of 1.8 is generally accepted as being pure for a DNA sample and a ratio of 2.0 is generally accepted also as being pure for RNA. when the ratio is significantly lower in each case, it indicates that there is presence of protein, phenol or other contaminants.
APT and photovoltaic cells are simikar because
Answers
The question is incomplete, below is the complete question.
ATP and photovoltaic cells are similar because
A. they are both key components of plant cells.
B. they both produce chemical and electrical energy.
C. they are both key components of solar panels.
D. they both use energy from the sun to separate electrons from atoms.
The correct answer to the question is option D
ATP and photovoltaic cells are similar because THEY BOTH USE ENERGY FROM THE SUN TO SEPERATE ELECTIONS FROM ATOMS.
Photovoltaic cells are otherwise known as solar cells,they are made of silicone that are specially treated,these specially treated silicon transfers solar energy gotten from the sun to electrical energy.
These solar powered photovoltaic panels converts the rays from the sun into electricity.this it does by exciting electrons found in silicon cells and also using the photons of light from the sun.
When this electricity is generated,it can be used to supply energy that is renewable to ones home or business.
In ATP, during the process of photosynthesis, sunlight penetrates the cell and further pass into the chloroplast. This light energy is further intercepted by granal stacks containing chlorophyll molecules, from then,some of those light energy are concerted to chemical energy,as this is going on,a phosphate is then added to a molecule to give rise to ATP.
How does the water on earth regulate the earth temperature
Answers
Answer:
It absorbs a lot of the sun’s energy.
Explanation:
A large portion of the sun’s energy and heat is absorbed by the oceans, which causes water to evaporate. Water has a high heat capacity, and therefore absorbs a large portion of the sun’s heat, regulating the earth’s temperature.

(ANSWER NEEDED NOW PLS!!) your sister claims that
the digestive system works by itself to give your body energy. She states that small branches from the stomach get food to the cells throughout your body. Do you agree with this statement? Why?
Answers
My sister is right. The stomach has structures in its branches that see to the breakdown of food materials.
The digestive system is the system in the body that takes care of the breakdown of food materials and absorption of nutrients from food. The stomach houses most of the structures in the digestive system.
When food is broken down in the stomach, It is sent to other parts of the body via the circulatory system in the body. Therefore, my sister is right.

Radish flowers may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being dominant. If true breeding red, long radishes are crossed with true breeding white, oval radishes, what will the offspring look like?
Answers
Answer:
The offspring will be purple and long
Explanation:
Radish flowers = Red, purple, or yellow
For a cross between a red-flowered plant and a white-flowered plant to yield all-purple offspring, that means either the red or white is dominant and the other recessive.
When cross it will result in 16 progenies.

A) Transcription factor X will no longer be able to go to the nucleus
B) A vesicle bud will no longer be pinched off from a membrane
C) A vesicle will no longer be tethered to a target membrane
D) A protein will no longer be targeted to the mitochondrial matrix
E) Two of the above
Answers
Answer:
B) A vesicle bud will no longer be pinched off from a membrane
Explanation:
Dynamin is a protein responsible for endocytosis, the process where the cell takes substances in from outside the cell through a system of vesicles. At the edge of the cell, the membrane pinches in to form a vesicle, which buds off from the membrane and enters the cell.
The step of this process that dynamin is involved in is in cleaving newly formed vesicles from the membrane. Without it, a vesicle bud will no longer be pinched off from a membrane
3. How far can an S-wave travel in 6 minutes 40 seconds?
Answers
Answer:
1800km
Explanation:
This question will be answered using the attached S-wave graph.
The graph is plotted as time (y axis) against distance (x axis).
So, when
y = 6 minutes 40 seconds
x = 1.8 * 10³ km
So, we have:
x = 1.8 * 1000km
x = 1800km

B. Living things store extra sugars as complex carbohydrates.
C. They contain carbon, hydrogen and oxygen, usually in the ratio of 1:2:1.
D. Carbohydrates are the main component that makes up cell membranes
Answers
Answer:
D. Carbohydrates are the main component that makes up cell membranes
Explanation:
The main component of the cell membrane is a double layer of phospholipids - molecules with a phosphate head and fatty acid tail. Therefore D is incorrect. There are some carbohydrates in the cell membrane, but they are not the main component.
The statement 'carbohydrates are the main component that makes up cell membranes' is NOT true (Option D).
Carbohydrates are biopolymers composed of monosaccharide units linked by glycosidic bonds.Complex carbohydrates (e.g., starch) consist of large branched or unbranched chains of monosaccharides, while simple carbohydrates (e.g., glucose) are monosaccharides.Complex carbohydrates serve as sources of longer energy storage for the cells, while monosaccharides provide energy quickly.The main component of the cell membranes are lipids (i.e., phospholipids and cholesterol).In conclusion, the statement 'carbohydrates are the main component that makes up cell membranes' is NOT true (Option D).
