3.You might think this should mean you need to cut out salt completely, but salt is actually an important nutrient for the human body. Your body uses salt to balance fluids in the blood and maintain healthy blood pressure, and it is also essential for nerve and muscle function.
4.Cooling the mixture is to prevent the DNA from being degraded by the heating.
5.The ethanol pulls water from the DNA molecule so that it then collapses in on itself and precipitates. The DNA will become visible as white mucous strands that can be spooled with the wooden applicator stick.
6.The colder the ethanol is the greater the amount of DNA that is precipitated. (You could try having some of the students use room temperature ethanol and see if the amount of DNA they can spool is the same or less than that for the groups using the ice-cold ethanol.
7.The reason is every strawberry seed contains different genetic material, the product of a myriad of potential gene combinations. Because the genetics of strawberries are so diverse (humans are diploid, strawberries are octoploid)

3. There are multiple types of mutations in DNA.
mutations occur when a single base is
changed to a different base pair.
mutations remove one or more bases from a segment of DNA,
resulting in a frameshift mutation.
mutations are also considered frameshift mutations, and occur when
one or more extra bases are added to a segment of DNA.
Check Answer
Answer:
substitution, deletion, insertion (in that order)
Explanation:
I did the assignment-
Mutations occur when a single base is changed to a different base pair; mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation, so this is also correct in other statements.
What is the significance of the DNA mutation?Mutations in DNA lie in their ability to alter the genetic information, and that altered information is passed on to next generations while Some mutations have no effect on the function of the proteins, but some have serious effects. It helps in the evolution process by providing a mechanism for the development of new traits, etc., in nature, so it has a significant role in it.
Hence, mutations occur when a single base is changed to a different base pair; mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation, so this is also correct in other statements.

Answer:
D.
Explanation: Which pieces of information does the National Weather Service produce?
simple maps
newspaper maps
long-range forecasts
maps with isotherms
The National Weather Service produces long-range forecasts and maps with isotherms, but not simple maps or newspaper maps.
What is long- range forecast?Long-range forecasts are predictions of weather conditions that are expected to occur over a period of several days or weeks. These forecasts are typically based on computer models that analyze current weather data and historical weather patterns.
Isotherms are lines on a map that connect points with the same temperature. They are commonly used to show temperature patterns across a geographic region, and can be useful for understanding weather conditions and climate trends.
While the National Weather Service may produce maps, they are typically not simple maps or newspaper maps, as their focus is on providing accurate and detailed weather information to the public and other stakeholders.

In many parts of the world, there is a rock layer rich in the metal iridium. Iridium is very rare on Earth, but it is relatively common in meteorites and other debris that comes from outer space. All occurrences of this iridium layer are from the same geologic epoch, at the very end of the Cretaceous. Most of the fossils in rock layers below the iridium layer, including dinosaur fossils, do not appear in layers above the iridium layer.
Based on this evidence from the rock and fossil record,
A.
meteoroids and other space debris did not impact the Earth at the end of the Cretaceous.
B.
an asteroid impact likely caused a mass extinction at the end of the Cretaceous.
C.
meteorites and other space debris no longer contain the metal iridium.
Answer:
B.
an asteroid impact likely caused a mass extinction at the end of the Cretaceous.

The missing part of the question is -
" Is this Primary or Secondary Succession?"
Answer:
The correct answer is - secondary succession.
Explanation:
Recolonization of the plant and animals to habitat after a major disturbance such as flood, lava eruption, wildfire, or human disturbance is characterized as secondary succession.
In this particular case, there is secondary succession occurs, there is man-made disturbance tajes place as logging company clear the spruce trees from a habitat, and after clearing the land the spruce seedlings began to sprout, birds, rabbits recolonize to the area.

Explanation:
The area of the picture highlighted by the green square is a monomer of nucleic acids(DNA/RNA). Which of the following is the name for that monomer?
A. phosphate backbone
B. thymine
C. nucleotide
Answer:
C. Nucleotide
Explanation:
There are four types of biological molecules existing in nature. These are: carbohydrates, proteins, lipids, and nucleic acids. Nucleic acids are biological polymers made up of monomeric units called NUCLEOTIDES.
A nucleotide as depicted in the attached image is a molecule made up of three components namely; Penrose sugar, phosphate group, and nitrogenous base (adenine, guanine, cytosine and thymine). Based on the image in this question;
A represents ADENINE
S represents SUGAR
P represents PHOSPHATE GROUP
Hence, the monomer is a NUCLEOTIDE.
Ion pumps and phagocytosis are both examples of
________.
a. endocytosis
b. passive transport
c. active transport
d. facilitated diffusion
Answer:
A
Explanation:
EDGE2021
Ion pumps and phagocytosis are both examples of active transport. Therefore, the correct option is C.
The movement of molecules or ions across the cell membrane against a gradient of concentration, from an area of lower concentration to an area of higher concentration, is called active transport. In this whole process energy must be used in the form of ATP (adenosine triphosphate).
Ion pumps are membrane proteins that actively transport ions across the concentration gradient across the cell membrane. These ions include sodium, potassium, calcium or hydrogen ions. The ion concentration imbalance required for many cellular functions is maintained by these pumps.
On the other hand, phagocytosis is a type of endocytosis in which cells engulf large molecules or solid particles and internalize them. Energy is required for the formation of pseudopods and for the solubilization of substances in the phagosome inside the cell.
Therefore, the correct option is C.

Why is blood type AB+ considered the universal receiver?
O It has no antibodies that can attack the antigens on the red blood cells of the other blood types.
It has no antigen on its red blood cells that can be attacked by the antibodies in the other blood types.
o It has no Rh antigen on its red blood cells that can be attacked by the antibodies in the other blood types.
O It has no A and B antigens on its red blood cells that can be attacked by the antibodies in the other blood types.
Answer:
the first one: It has no antibodies that can attack the antigens on the red blood cells of the other blood types.
Explanation:
edge 2021
AB positive and O negative are considered as universal blood types. AB+ has no antibodies that can attack the antigens on the red blood cells of the other blood types. The correct option is A.
What is universal receiver?The people with AB+ blood group are called as the universal receivers. They can safely receive a blood transfusion using any other blood type. Having a universal blood type can save a life of yours or someone else in an emergency.
If you have an AB+ blood type, you have both A and B antigens. Since a person has all of the antigens that are possible, this blood type is the rarest. The AB+ blood type has a positive Rh factor, the recipient will not reject the blood. So it can get any type of blood.
AB type blood has no antibodies against type A or type B blood. So a person with AB blood can receive any type of blood.
Thus the correct option is A.
