Hershey and Chase's work supported the findings of Avery's team by providing evidence for option D: "It showed that a virus's heritable information is also carried by DNA."

Hershey and Chase conducted an experiment using bacteriophages, which are viruses that infect bacteria. They labeled the DNA of the bacteriophages with radioactive isotopes and the protein coat with a non-radioactive substance. They then allowed the labeled bacteriophages to infect bacteria.

After infecting the bacteria, they used a blender to separate the protein coats of the bacteriophages from the bacteria. They observed that the radioactive DNA was transferred into the infected bacteria, while the non-radioactive protein coats remained outside. This experiment provided conclusive evidence that the heritable information of the bacteriophage, which determines its traits, is carried by DNA and not the protein coat.

This supported the earlier findings of Avery's team, who demonstrated that DNA is the substance responsible for carrying genetic information and passing it on to offspring. Hershey and Chase's work further solidified the understanding that DNA is the genetic material responsible for inheritance. Therefore, Option D is correct.

A nuclease (also archaically known as nucleodepolymerase or polynucleotidase) is an enzyme capable of cleaving the phosphodiester bonds between nucleotides of nucleic acids. Nucleases variously effect single and double stranded breaks in their target molecules. In living organisms, they are essential machinery for many aspects of DNA repair. Defects in certain nucleases can cause genetic instability or immunodeficiency.[1] Nucleases are also extensively used in molecular cloning.[2]

Amplification cascade

Explanation:

Amplification cascade also known as Signaling pathway occurs when a stimulus or first messenger prompts a biological reaction within a cell which in turn acts on a receptor that undergoes signal transduction and amplification caused by secondary messengers. These secondary messengers send the signal to the effector sites who now produce a response to the initial stimuli.

So, the basic principle of an amplification cascade is the fact that a particular action triggers the response of several other factors. This is similar to what Genna describes in her experiment where a metabotropic receptor activated multiple proteins.

Cells link amino acids together by peptide synthesis. The resulting bond between them is called a peptide bond.

Amino acids are organic molecules that are the building blocks of proteins. They contain an amino group (-NH2), a carboxyl group (-COOH), and a side chain that is unique to each amino acid.

There are 20 different amino acids that are commonly found in proteins, and they differ from each other based on the chemical structure of their side chains.

During protein synthesis, amino acids are linked together in a specific order to form a polypeptide chain, which folds into a three-dimensional protein structure.

Peptide bonds are covalent bonds that link two amino acids together in a protein chain during peptide synthesis. The bond forms between the carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of another amino acid, releasing a molecule of water in the process.

This results in the formation of a peptide bond (-CO-NH-) between the two amino acids, and the chain of amino acids linked by peptide bonds is called a polypeptide chain.

The sequence of amino acids in a polypeptide chain determines the protein's unique three-dimensional structure and its function.

Answer:

B. Carbon dioxide is the primary source of organic material in plants.

Plants are autotrophs, which means they produce their own food through the process of photosynthesis. During photosynthesis, plants use energy from sunlight to convert carbon dioxide (CO2) and water (H2O) into organic molecules like glucose, which they use as a source of energy and building material. Oxygen (O2) is also produced as a byproduct of photosynthesis.

While water and soil minerals are important for plant growth and development, they do not contribute significantly to the organic mass of the plant. Nitrogen is also important for plant growth and is a component of many organic molecules, but it is not the primary source of organic material in plants.

Therefore, the correct answer is B. Carbon dioxide, which is converted into organic material during photosynthesis, is the main source of the plant's organic mass.

Answer: B, carbon dioxide

Explanation:

the mass is primarily carbon because the carbon comes from the carbon dioxide used during photosynthesis. during photosynthesis, plants will convert the sun's energy into a chemical captured within the bonds of carbon molecules created from carbon dioxide and water. The Caborn ends up in the plant's food as well

The key difference between prokaryotic and eukaryotic cells that can be exploited when using antibiotics is the structure and composition of their cellular components. Prokaryotic cells, such as bacteria, have simpler structures, lacking membrane-bound organelles like nuclei, mitochondria, and endoplasmic reticula.

Eukaryotic cells, found in animals, plants, and fungi, have more complex structures and contain these membrane-bound organelles.

Antibiotics target specific components of prokaryotic cells that are not present or significantly different in eukaryotic cells. For example, antibiotics can target the bacterial cell wall, which is made up of peptidoglycan.

Eukaryotic cells do not have a cell wall made of peptidoglycan, so these antibiotics specifically affect prokaryotic cells without harming eukaryotic cells.

Another difference that can be exploited is the ribosomes, which are responsible for protein synthesis. Prokaryotic ribosomes are smaller (70S) compared to eukaryotic ribosomes (80S). Some antibiotics, like tetracyclines and macrolides, selectively target the bacterial 70S ribosome, preventing protein synthesis and eventually killing the bacterial cell without affecting the eukaryotic cells.

In summary, the structural differences between prokaryotic and eukaryotic cells, such as cell wall composition and ribosome size, can be exploited when using antibiotics to selectively target and eliminate prokaryotic cells without causing harm to eukaryotic cells.

The speed of the wave is 112 meters per second.

The speed of a wave is a fundamental property of waves and is determined by the medium through which the wave travels. For example, the speed of sound waves depends on the temperature and density of the medium through which they are traveling, while the speed of light waves depends on the refractive index of the medium through which they are passing.

The speed of a wave can be calculated using the equation:

speed = wavelength x frequency

where wavelength is measured in meters and frequency is measured in hertz.

Given that the wavelength of the wave is 7 m and the frequency is 16 Hz, we can plug these values into the equation to calculate the speed of the wave:

speed = 7 m x 16 Hz

speed = 112 m/s.
