A student describes a substance as lacking a definite shape. The description also states that the particles of matter are close to each other but still able to flow past each other. Which type of substance

is the student MOST likely describing?

A

solid

B

liquid

oc

mixture

D compound

Answers

Answer 1

Answer: A

Explanation:

Answer 2

The correct option is A. Solid has a definite shape. In solids, the particles are closer to each other.

What is solid?

There are three states of matter. They are solid, liquid and gases. Solid has a definite shape. The particles are much closer and there are the least intermolecular spaces between them.

Many materials can be used to create solids. They may be made of different compounds or just pure elements. A mixture is a substance that contains more than one type of chemical.

The majority of rocks are assemblages of various chemicals. A good illustration of a man-made solid combination is concrete.

Therefore, The correct option is A. Solid has a definite shape. In solids, the particles are closer to each other.

Which of the following combinations is always true of the nucleotide composition of a sample of DNA?

Answers

Answer:

I'm dead

Explanation:

Bruh you literally go to my school. I'm dying over this.

The combination which is always true of the nucleotide composition of a sample of DNA is:  [tex]A + C = G + T[/tex]

Deoxyribonucleotides is the basic unit of a deoxyribonucleic acid (DNA).

Basically, it comprises a nitrogenous base and phosphate group that are commonly known as deoxyribose sugar.

A nucleotide refer to a subunit of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) that consists of a nitrogenous base.

Hence, the nitrogenous base or nucleotide composition of a deoxyribonucleic acid (DNA) includes the following:

Adenine (A).Guanine (G).Cytosine (C).Thymine (T).

In conclusion, the combination which is always true of the nitrogenous base or nucleotide composition of a sample of DNA is:

Answer:

First Option

Explanation:

When you consume food and it goes through your digestive system your body takes a good amount of the good and converts it into energy and distributes it throughout your body leaving the rest of the food as waste then it will soon leave the body in it's own way as it reaches the end of the digestive cycle. In this case the animal consumed food and then the body converted it into energy causing the animal to gain mass or "grow."

2. What is the NADPH responsible for?
3. Where do the "light" reactions (light-dependent) take place?

Answers

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.

Answer:

It means that it lowers the activation energy of a reaction and can be used again.

Explanation:

A catalyst is a substance that allows the chemical reaction to occur at a faster rate or under different conditions (e.g. at a lower temperature) without being affected by the reaction.

The activation energy is the minimum energy required for the reaction to occur. Catalysts lower this energy and can be used again, which is why the last option is the correct one.

Codominance

So this would either be codominance or incomplete dominance. With incomplete dominance, you tend to get a whole other colour- for example crossing black and white chickens and getting a blue chicken. If you cross brown and white, and get a mix, it must be codominance because both traits are shown.

Researchers want to use eDNA to look for an invasive species in a waterway.

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.

Answers

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).
