Researchers want to use eDNA to look for an invasive species in a waterway.
Which step should they do last?
A. Cut the DNA into fragments of different sizes.
B. Compare the samples with a positive control.
C. Isolate DNA from the waterwakin question.
D. Stain the gel to reveal a banding pattern.
The last step to observe different DNA patterns is to stain the gel to reveal a banding pattern (Option D).
DNA extraction, polymerase chain reaction (PCR) and fragment separation by gel electrophoresis are basic molecular techniques used to identify patterns in DNA.The patterns in DNA can be used for identifying an individual in a population, distinguishing different species, etc. These patterns can be obtained by using restriction enzymes.There are different dyes used to stain DNA before the identification of patterns in DNA.For example, ethidium bromide is a widely used dye to stain DNA before fragment separation by agarose gel electrophoresis.In conclusion, the last step is TO STAIN the gel with a DNA dye to reveal a banding pattern (Option D is correct).

Which researcher proposed that dreams are a chance for problem solving? A. Sigmund Freud B. Matthew Wilson C. Rosalind Cartwright D. J. Allan Hobson
Answer:
The answer is Rosalind Cartwright.
Explanation:
A researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.
What is Problem-solving?Problem-solving may be defined as an instance of illustrating a problem that significantly determines the consequences of the problem along with identification, prioritization, and selection of alternatives for a solution; and implementing a solution.
Rosalind Cartwright was a neuroscientist who proposed the theory of dreams with respect to the chance for problem-solving. She hypothesized the complete mechanisms of dreaming which is particularly based on REM sleep. It is a way to process emotions, experienced during the day.
Therefore, a researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.

Because most nerve cells do not typically undergo mitosis, they are generally not capable of which of the following?a.producing enzymesb.generating more nerve cellsc.performing cellular respirationd.transporting ions against a concentration gradien
Answer:
B. generating more nerve cells
Explanation:
Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.
Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.

2. What is the NADPH responsible for?
3. Where do the "light" reactions (light-dependent) take place?
Answer:
A) Light dependent reactions
Reactants: light, H2O
Products: Oxygen gas
B) Light independent reactions
Reactants: C02
Products: Glucose
2. NADPH is an electron carrier which transfers electrons in the electron transport chain of photosynthesis
3. Light reactions occur in the THYLAKOID membrane.
Explanation:
As depicted in the image in this question, the photosynthetic process can be grouped into two stages viz; light dependent reactions and light independent reactions. The light dependent reactions, which take place in the THYLAKOID MEMBRANE of the Chloroplast, involves the synthesis of ATP (energy carrier) and NADPH (electron carrier) to be used in the next stage. The reactants of light dependent reactions are light energy from sun, and water (H2O) while the product is Oxygen (O2) gas.
In the light independent reactions, the ATP and NADPH are used to synthesize GLUCOSE as a product from Carbon dioxide (CO2) reactant.
2. The NADPH is is an electron carrier produced from the reduction of NADP+, which transfers or donates electrons to other molecules in the electron transport chain of photosynthesis. This is crucial in building of the proton gradient for ATP production.
3. The light reaction or light dependent reaction takes place in the THYLAKOID MEMBRANE of the Chloroplast.
The light-dependent reactions use ADP and NADP to produce NADPH and ATP (it occurs in the thylakoid membrane), whereas light-independent reactions use NADPH and ATP. NADPH is a cofactor.
The light-dependent reactions use sunlight and water (H2O) to produce oxygen (O2), NADPH and ATP, whereas light-independent reactions use carbon dioxide (CO2) NADPH, and ATP to produce simple carbohydrates (e.g., glucose).Both light-dependent reactions and light-independent reactions occur in the chloroplast: light-dependent reactions occur in the thylakoid membrane of the chloroplast, whereas light-independent reactions occur in the stroma of the chloroplast.Reduced nicotinamide adenine dinucleotide phosphate (NADPH) is a cofactor that transports electrons (e-) and protons (H+) released by sunlight into new carbon-carbon bonds and thus serves to produce simple carbohydrates (i.e., sugars).In conclusion, the light-dependent reactions use ADP and NADP to produce NADPH and ATP (it occurs in the thylakoid membrane), whereas light-independent reactions use NADPH and ATP to create carbohydrates.

Explain the differences between the three ways of heat transfer, conduction, convection, and radiation.
Answer:
The differences between these three ways of heat transfer are that conduction is the transfer of thermal energy through direct contact, convention is the transfer of thermal energy through the movement of liquid or gas, and radiation is the transfer of thermal energy through thermal emission. As you can see, each way of heat transfer has a different way of moving through objects.

Which of the following occur during interphase? Select all that apply.
A) cells prepare for cell division
B) chromosomes divide
C) cytoplasm divides
D) cells grow rapidly
E) chromosomes replicate
Cells grow rapidly and hromosomes replicate are occurs during interphase.
What do you mean by interphase?Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

Why is this statement true?
O Hydrogen is a gas, but oxygen is a solid.
O Hydrogen atoms have a lower mass than oxygen atoms.
• Hydrogen atoms make up more of water's mass than oxygen atoms.
Hydrogen is present as single atoms and oxygen is bonded in compounds,
Answer:
Hydrogen atoms have a lower mass than oxygen atoms.
Explanation:
The statement which is true is Hydrogen atoms have a lower mass than oxygen atoms. Thus, option C is correct.
What is hydrogen?
Hydrogen is the most abundanet element representing nearly three quarters of the mass of the universe. Hydrogen is found in the water that covers 70% of the surface of our planet as well as in all organic matter. Hydrogen is the simplest element in the universe. It is composed only of one proton (p) and only one electron (e-).
Hydrogen is the lightest element of all elements and gases; it is 14 times lighter than air. A "spill" of hydrogen gas immediately diffuses into the air and pollutes neither the ground nor the water table. Hydrogen is invisible, odorless and nontoxic. It does not cause acid rain, does not deplete the ozone layer and does not generate dangerous emissions.
Carbon is so abundant in living things even though oxygen is the most abundant element on Earth because carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures.
Therefore, The statement which is true is Hydrogen atoms have a lower mass than oxygen atoms. Thus, option C is correct.
