The ___ in an experiment is the factor that is being
changed, or tested.
- control group
- dependent variable

- constant
Answer:
Independent Variable
Explanation:
The independent variable is what we are changing or what is being tested.
The control/constant group is when you do not change anything and you want to see how the object acts under normal conditions.
The dependent group is what you are measuring. (aka your data/results)

Ethan began making a model to show the processes which resulted in the formation of oceans
Which of the following would be the next step in the process?
Crust is broken down
Earths crust moves
Earths plates meet
Sea floor spreading
The next step in the process is sea floor spreading. The correct option is D.
What is sea floor spreading?Tectonic plates, which are huge chunks of the lithosphere of the Earth, split apart from one another during the geologic process of seafloor spreading.
The oceanic basin is the result of sea floor spreading.
The ocean crust and its basins are formed when the sea floor spreads and separates after the basin has been filled with water.
All of these result from various plate interactions within the planet.
New ocean floors are created by volcanic activity at spreading centers at divergent borders after the crust has developed and accumulated water.
The production of fresh crust occurs close to the margin, and subsequent crusts push against and away from it. Ocean basins are created by the development of new ocean floors.
Thus, the correct option is D.

What would be considered a quantitative observation
Answer:
height of radish seedlings is measured.Quantitative observation is a method of collecting objective data that is largely focused on numbers and values — the phrase means "related with, of, or portrayed in terms of a quantity." Sending out surveys, questionnaires, or polls is a common method of quantitative observation.
quantitative observation include age, weight, height, length, population, size, and other numerical values while, qualitative observation are color, smell, taste, touch or feeling, typology, and shapes.

DNA's genetic information is copied to form ___ RNA, which then delivers it to the ___ where protein synthesis occurs.
Answer:
DNA's genetic information is copied to form mRNA, which then delivers it to the ribosome where protein synthesis occurs.
Explanation:
During transcription, RNA polymerase uses a single-stranded DNA template to synthesize a complementary strand of RNA. The mRNA then travels from the nucleus to the cytoplasm where ribosomes are found. Ribosomes are structures that are responsible for making proteins.

A cell membrane is very specific about what it allows to cross.how does this help the cell?
Answer:
The cell membrane is selectively permeable . It lets some substances pass through rapidly and some substances pass through more slowly, but prevents other substances passing through it at all. Some small molecules such as water, oxygen and carbon dioxide can pass directly through the phospholipids in the cell membrane

Explanation:
a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

Explanation:
Which of the following statements is true? Which of the following statements is true? No archaea are capable of using CO2CO2 to oxidize H2H2, releasing methane. Prokaryotes have low levels of genetic diversity. Archaea and bacteria have identical membrane lipids. The cell walls of archaea lack peptidoglycan.
Answer:
The correct answer is - The cell walls of archaea lack peptidoglycan.
Explanation:
Archaea are the prokaryotes that are different from bacteria in various ways but the most important differences are the membrane lipids and the major component of the cell wall that lacks peptidoglycan found in the cell wall of bacteria.
These prokaryotes are able to use carbon dioxide to oxidize hydrogen, releasing methane. Archaea-like prokaryotes have a high level or complex genetic diversity.

Translate the sequence of amino acids in sickle-cell hemoglobin into (use third valine)
a) mRNA base codes
b) tRNA base codes
c) DNA base codes
Answer:
Sickle cell hemoglobin occurs in the beta chain of hemoglobin due to point mutation in the sixth codon which changes from glutamic acid to valine which is hydrophobic that causes the change in the size of the RBC in a crescent shape.
The protein or amino acid chain of this condition is as follows:
Protein with Sickle Mutation: VAL HIS LEU THR PRO VAL GLU
which is translated from mRNA sequence
mRNA with Sickle Mutation: G U G C A C C U G A C U C C U G U G G A G
mRNA sequence is the complementary sequence or anticodons of the mRNA sequence RNA:
tRNA with Sickle Mutation: C A C G U G G A C U G A G G A C A C C U C
mRNA sequence is transcribed from the transcription strand of DNA sequence:
DNA with Sickle Mutation: C A C G T G G A C T G A G G A C A C C T C
In arthritis, there is deposition of urate crystals in joints. If you want to treat the arthritis by decreasing the concentration of circulating uric acid, what will you do with its mechanism in kidney?
Answer and explanation:
If I'd wanted to decrease the concentration of circulating uric acid by altering its mechanism in the kidney, I would administer a drug that would inhibit uric acid reabsorption and increase its excretion through urine.
Arthritis is a condition characterized by inflammation of the joints and can be caused by many diseases. When the cause of this arthritis is the deposition of urate crystals in the joint because of an increase in the concentration of circulating uric acid (hyperuricemia) we are most likely talking about gout, a painful disease that can deform the joints.
Hyperuricemia and gout have many risk factors associated with them, such as genetic predisposition, unhealthy diet, and suffering from other conditions like Diabetes.
Several medications are used in the treatment of the symptoms and the prevention of the worsening of this disease, but the one that is most frequently used to increase the excretion of uric acid is Probenecid. Probenecid blocks the kidney's OAT (organic anion transporter) that reabsorbs uric acid in the kidney tubules, thus enhancing its excretion and decreasing uric acid's blood concentration.
