A model of the infection of a host cell by a virus is shown here. Which statements accurately describe the processes involved in viral infection and replication? Select two that apply.

Answers

Answer 1

The infection of a host cell by a virus is done, the virus releases the genetic content in the host cell, the genetic content is replicated using the host enzymes, and the viral infection spreads.

What is the cause of the viral infection?

The viral infection is caused by the virus when it attaches to the host cell and releases its genetic content, which is later replicated in the host cell and released through the host cell and this is called the lytic cycle of the virus while in lysogenic cycle the virus keeps developing in the host cell as the genome is incorporated in the host genome.

Hence, the infection of a host cell by a virus is done, the virus releases the genetic content in the host cell, the genetic content is replicated using the host enzymes, and the viral infection spreads.

Answers

The statement that is incorrect is that somatic mutations are numerous, occurring at a rate one per every million cell division. While somatic mutations do occur at a high rate, they are not as numerous as germ-line mutations and occur at a rate much lower than one per million cell divisions.

Gene mutations are changes in the sequence of DNA that affect a single gene and can be either germ-line or somatic mutations. Chromosome mutations involve changes in the number or structure of chromosomes, and can also be either germ-line or somatic mutations.

Mutations are a major source of genetic variation in a population and can be used to study biological processes. For example, mutations in genes can help us to understand how genetic variation affects the phenotype of an organism. Mutations can also be used to create model organisms, such as those used in cancer research.

The ________ and __________ are the vessels in the fetal pig heart that is absent in adults.

Answers

The foramen ovale is the part of the adult heart that corresponds to the fetal heart's opening between its two atria.

In contrast to adult pig hearts, the foramen ovale is not present in fetal pig hearts. Between the right and left auricle, there is a little gap that allows blood to flow freely.

The foramen shuts immediately after birth as a result of rising pressure in the heart chambers, including the cessation of placental flow, which raises right atrial pressure, and the aeration and ventilation of the lungs, which raises venous return from the lungs and raises left atrial pressures.

During fetal development, blood can flow from the right atrium to the left atrium through a hole in the heart tissue called the foramen ovale.

Muscle fiber contraction occurs via the generation and transmission of: Select one: a. Excitation-Contraction Coupling b. Action Potentials c. Power Strokes d. Twitch Fibers

Answers

Option B is the right answer. Muscle fiber contraction occurs via the generation and transmission of: Action potential.

The phrase "excitation-contraction coupling" (ECC), first used by Alexander Sandow in 1952, refers to the quick exchange of electrical information between electrical events happening in the plasma membrane of skeletal muscle fibres and Ca2+ release from the SR, which causes contraction. When a muscle fibre or set of fibres receives a signal from the brain via nerves to activate and increase tension inside the muscle, muscular contraction takes place. Activation of muscle fibres is another name for it. Three distinct muscle types make up your body, and there are three ways in which they might contract. The neuromuscular junction, which is the synapse between a motoneuron and a muscle fibre, is where skeletal muscle contraction starts.

What blood type has antibodies for a B and Rh antigens?

Answers

The blood type that has antibodies for both B and Rh antigens is the O negative blood type. This type of blood is considered the universal donor, meaning it can be safely transfused to any other blood type without fear of the recipient's body rejecting the donated blood.

The O negative blood type is extremely rare, making up only about 7% of the population. It is the only type of blood that has no antigens present, meaning that it is the only type of blood that does not contain either the A, B, or Rh antigens. This makes it ideal for transfusions as it is not compatible with any other blood type.

The B antigen is the most common blood antigen, and the Rh antigen is the second most common. Both of these antigens can cause a reaction when transfused to someone with a different blood type. Due to the lack of these antigens in O negative blood, it can safely be given to someone of any other blood group without fear of a reaction.

dna is made up of different types of nucleotides. which part of a nucleotide is used to determine one nucleotide from another?

Answers

DNA is the genetic material found in all living organisms. It is composed of four nucleotides: adenine (A), cytosine (C), guanine (G) and thymine (T). These nucleotides are the building blocks of DNA and provide the genetic code that determines the structure and function of an organism.

A nucleotide is composed of three parts: a five-carbon sugar molecule, a nitrogenous base, and a phosphate group. The five-carbon sugar molecule is the same for each nucleotide, but the nitrogenous base is different for each nucleotide. For example, adenine has a nitrogenous base of adenine, cytosine has a nitrogenous base of cytosine, and so on. The nitrogenous base is the part of the nucleotide that is used to determine one nucleotide from another.

The nitrogenous bases are classified into two groups: purines and pyrimidines. Purines are larger molecules with two nitrogenous bases, adenine and guanine, while pyrimidines contain one nitrogenous base, cytosine and thymine. Each nucleotide is unique because of the specific nitrogenous base that it contains. For example, adenine is only found with thymine, and guanine is only found with cytosine. This is known as complementary base pairing and is essential for DNA replication.

Which statement best summarizes save the coral reefs quizlet?

Answers

Coral reefs are an essential part of the ocean's ecosystem because they provide a home for creatures like crabs and sea turtles. In fact, bleaching is destroying the reefs, which are necessary for the existence of nearly 4,000 species. To save the reefs, more needs to be done right away. Hence, the first statement is correct.

One of the most significant ecosystems in the world is the coral reef. A healthy coral reef can supply some of the most important and required ecological services. They offer food for millions of people, shield the coastlines from storms and erosion, serve as vital fish species' nursery habitats, generate cash for nearby communities through recreation, tourism, and fishing, and serve as a source of new medications.

Numerous species of fish, crabs, shrimp, urchins, sponges, algae, sea turtles and other organisms can be found in coral reefs. Because they have access to a variety of food sources and may hide from predators, these organisms choose to live on coral reefs.

Coral reefs hardly regrow once these corals die because of bleaching. Coral populations are dwindling, making it impossible for them to procreate and endangering the entire reef ecosystems that house both wildlife and humans. As a result, coral reef protection is crucial.

The complete question is -

Which statement best summarizes "Save the Coral Reefs"?

a) Coral reefs are a very important component of the ocean's ecosystem because they support sea life, such as crabs and sea turtles. In fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. More must be done immediately to save the reefs.

b) Development along the coastal regions has significant negative effects on coral reefs. The reefs are an essential part of the ocean's ecosystem, and when people build structures on top of them, they are easily damaged because they are so fragile. We should limit construction along the coast to protect the reefs.

c) Construction along the coasts, overfishing, and bleaching have seriously damaged the world's coral reefs. Since reefs are a very important part of the ocean's ecosystem, their destruction has a devastating environmental impact, and we must work to protect them.

d) Coral reefs are fragile structures made of limestone. People who build in coastal regions and others who overfish our seas must be stopped, because they don't care about all the species that rely on the survival of reefs, such as sea turtles, clownfish, lobster, sharks, and crabs.

What is gene expression?

Gene expression refers to the process by which the information encoded in a gene is used to produce a functional product, such as a protein.

In prokaryotes (bacteria), transcription is the process by which the information in a gene is copied into RNA. This is carried out by an enzyme called RNA polymerase. The template strand of the DNA, which carries the information for the gene, is used as a template to synthesize a complementary RNA molecule. The resulting RNA molecule is called messenger RNA (mRNA).

In eukaryotes (organisms with a true nucleus, such as plants and animals), transcription is a more complex process. The DNA is first transcribed into a primary transcript called pre-mRNA. The pre-mRNA then undergoes a series of processing steps, including splicing, to remove non-coding segments called introns. The resulting mature mRNA is then ready to be used in protein synthesis.

Transcription is regulated at various levels, including at the level of transcription initiation, elongation, and termination. Transcription factors, which are proteins that bind to specific DNA sequences, play a key role in regulating transcription.
