G the host range of a virus is determined by the proteins in the host's cytoplasm.

Proteins that include enzymes aid in accelerating our bodies' chemical processes, or metabolism. While certain compounds are decomposed, others are produced. Enzymes are present in all living things. Our bodies naturally manufacture enzymes. Enzymes are, however, found in both food & manufactured goods.

Your kidneys, small intestine, nor stomach all make digestive enzymes. The pancreas is actually the "powerhouse" of the digestive enzymes. It produces the most important digestive enzymes, which disintegrate proteins, lipids, and carbohydrates. The lipase enzyme is used by the body to break down dietary fats so that the intestine can digest them. Lipase is produced in the stomach, mouth, and liver.

Explanation:

We can characterize viroids as short infectious single stranded RNAs that can infect some plants. Unlike prions, which are misfolded proteins that may infect humans and other animals causing spongiform encephalopathy, viroids are a distinct group of infectious agents that consist only of RNA, lacking the protein coat found in viruses. Viroids are known to cause diseases in a variety of plants, and are unique in that they do not encode any proteins, relying instead on host enzymes for replication and other functions. They are typically smaller than viruses, ranging from around 246 to 399 nucleotides in length, and have a characteristic secondary structure that includes regions of self-complementarity and base pairing. Overall, viroids are an interesting and important group of pathogens that provide unique insights into the molecular mechanisms of infectious disease

Viroids can be characterized as a group of infectious single-stranded RNAs that can infect some plants.

Viroids are small infectious single-stranded RNAs that can infect some plants. They are distinct from viruses because they have no protein coat. They are mostly found in potatoes and tomato plants. Viroids were discovered in the 1970s and their name comes from "virus-like" and "infectious" features. Viroids can cause many plant diseases, including crop loss and stunted growth. Prions, on the other hand, are proteins that can infect humans and animals, causing spongiform encephalopathy. They are not viruses, bacteria, or fungi. Single-stranded DNA viruses that infect animals are also known to exist.

The primary mechanism by which the outer ear amplifies incoming sound is through the funnel-like shape of the ear canal. This shape helps to collect and direct sound waves toward the eardrum, which vibrates in response to the sound. This vibration then sets off a chain reaction in the middle and inner ear that ultimately leads to the brain processing the sound. Additionally, the outer ear also plays a role in enhancing certain frequencies of sound through resonance, which can further amplify the sound.

if the codon for phe is 5'- u u c 3' , AAG is the anticodon that would be found on the trna that carries phe. Their function is to base pair with the codon on a strand of mRNA during translation.

An amino acid's specific genetic information is encoded by a codon, which is a DNA or RNA sequence made up of three nucleotides (also known as a trinucleotide). A trinucleotide sequence called an anticodon is found at one end of a transfer RNA (tRNA) molecule and is complementary to a corresponding codon in an mRNA sequence. During protein synthesis, each time an amino acid is added to a developing polypeptide, a tRNA anticodon couples with the corresponding codon on the mRNA molecule to ensure that the correct amino acid is incorporated into the polypeptide.

The anaerobic conversion of 2 glucose to 4 lactate is accompanied by a net gain of 2 ATP molecules.

During anaerobic glycolysis, glucose is converted to lactate in the absence of oxygen. This process occurs in various cells, including muscle cells during intense exercise. In this conversion, two molecules of glucose are metabolized to produce four molecules of lactate. Along with the production of lactate, there is a net gain of two ATP molecules. However, it is important to note that anaerobic glycolysis produces ATP less efficiently compared to aerobic respiration. In aerobic conditions, glucose is fully oxidized to carbon dioxide, resulting in a much higher ATP yield through the process of oxidative phosphorylation.

Spectrophotometers compare the light transmitted through a sample to the light transmitted through a blank.

The blank is a solution containing all the reagents except for the one being tested, and it serves as a reference to account for any absorption or scattering that may occur in the solvent or the instrument itself. By subtracting the blank absorbance from the sample absorbance, the spectrophotometer can determine the amount of light absorbed by the sample and thus the concentration of the compound being measured. This technique is widely used in analytical chemistry, biochemistry, and other fields to quantify the amount of a substance in a sample.

The correct statement about the elongation of the lagging strand is D. It requires one RNA primer to completely replicate.

During DNA replication, the lagging strand is synthesized in short fragments known as Okazaki fragments. The process of lagging strand synthesis requires the synthesis of RNA primers to initiate each Okazaki fragment. These RNA primers provide a starting point for DNA polymerase to begin synthesizing the DNA fragment.

Each Okazaki fragment on the lagging strand requires a separate RNA primer for initiation. Once the RNA primer is synthesized, DNA polymerase extends the fragment by adding complementary nucleotides in the 5'-3' direction. This process continues until the entire lagging strand is replicated.

While the leading strand is synthesized continuously in the 5'-3' direction, the lagging strand is synthesized discontinuously in short segments due to its orientation relative to the replication fork. These segments are later joined together by an enzyme called DNA ligase to form a continuous and complete lagging strand.

Therefore, the statement that best describes the elongation of the lagging strand is that it requires one RNA primer to completely replicate. Multiple RNA primers are necessary to initiate the synthesis of individual Okazaki fragments, which are then joined together during the process of DNA replication.

Flowers' importance in nature is everywhere—they can feed insects, birds, animals and humans; provide natural medicines for humans and some animals; and aid in a plant's reproduction by enticing outside pollinators. Without flowers, plants would merely be green, and the world would be a duller place.

Explanation:

Three main reasons in my view can be:

1) If flowers were not there, there would be no fruits either( which provides us about 90% nutrients ).

2) Flowers are also used to make medicines.

3) Flowers are food for many insects and some animals.
