C To manufacture enzymes using a host's immune system
D To remove a host cells's DNA

Answers

Surface proteins are the proteins that are embedded in the cell membrane structure of organisms and help in cell interaction with the outer surrounding or other cells.

Surface protein on the influenza virus is needed for attaching to the host cell.

The surface protein of viruses can be explained as:

In viruses, the genetic material is stored in these protein structures called capsids which protects the viral genetic material from degrading enzymes and other cellular enzymatic activities.

Surface proteins on the viruses are needed to penetrate and attach to the host system and cells for inducing immune response and diseases.

How did you determine the types of cell division for both phases depicted in your model? Explain your answer.

Answers

Answer:

Cell division is a process that makes our skin, tissues, muscles, sex cells. It is the building block of our body.

Explanation:

When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.

The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.

called CF is a condition that causes excess mucus production in the lungs and if untreated causes early death. CF is caused by a deletion of 3 letters in the gene sequence. How might this deletion cause excessive mucus production?

Answers

Answer:

The correct answer is - by absorbing too much sodium and water into the cells in the respiratory system.

Explanation:

Cystic fibrosis or CF is a genetic disorder that is caused by the presence of two defective genes that leads to the production of thick and sticky mucus in an individual that affects the respiratory and digestive system by clogging mucus in it.

Due to defective genes, there is an abnormal electrolyte transport system develops in which cells of the respiratory system including the lungs absorb an excessive amount of salt (sodium) and water. It all caused by deletion of the three letters which means an amino acid from a gene that leads to the disruption of the protein that controls the production of the mucus and abnormal electrolyte transport.

Help me describe how these protists feed, move, and reproduce.

A plant-like protist
A fungus-like protist
Ciliophoran
Zooflagellate
Sarcodinian
Sporozoan

Answers

Explanation:

Protists are mostly one-celled organisms. Some make

their own food, but most take in or absorb food. Most

protists move with the help of flagella, pseudopods, or

cilia. Some protists, like the one-celled amoeba and paramecium, feed on other

organisms.

Fungus-like protists share many features with fungi. Like fungi, they are heterotrophs, meaning they must obtain food outside themselves. They also have cell walls and reproduce by forming spores.

Ciliates reproduce asexually by division: the micronucleus undergoes mitosis, while in most ciliates the macronucleus simply pinches apart into two. This process is shown in the drawing above. However, ciliates also reproduce sexually, through a process known as conjugation. Conjugation is often induced by lack of food. Two ciliates of opposite mating types come close together and form a cytoplasmic bridge between the two cells; the micromuclei divide by meiosis, the macronuclei disintegrate, and the conjugating cells exchange haploid micronuclei over the cytoplasmic connection. They then separate, reform new macronuclei from their micronuclei, and divide, but remember that the essence of sexual reproduction is forming a new organism from the combined genetic material of parents. After conjugation, each ciliate partner has acquired new genetic material, and divides to give rise to progeny with a new combination of genes. This is essential to the survival of ciliate lineages; most ciliates cannot reproduce indefinitely by asexual fission, and eventually die out if prohibited from conjugating.

One convenient way to categorize protozoans is by how they move. Some move rapidly, while others creep slowly. Still others are not capable of active movement at all, but instead rely on a host organism to supply their food.

Protozoans With Flagella

Zooflagellates (zoh oh FLAJ uh lits) move by means of one or more flagella. (Recall from Chapter 6 that flagella are long, thin, whip-like cellular projections.) Zooflagellates generally reproduce asexually by binary fission. Recall that asexual reproduction results in genetically identical offspring.

Sarcodines reproduce sexually by syngamy (fusion of two gametes) and asexually by division or budding. In multinucleate forms, cytoplasmic division with distribution of the nuclei occurs.Members of the phylum Sarcodina are ameboid. They move about by using pseudopods and usually eat by phagocytosing food particles, usually bacteria. Some amoeba form calcium carbonate or silica skeletons called tests to protect themselves.

The sporozoans are able to form spore-like cells, from which they get their name. Sporozoans do not have flagella, cilia, or pseudopodia. They are capable of gliding movements. ... The apical complex secretes enzymes which allow the sporozoan to enter a host cell.Apicomplexan, also called sporozoan, any protozoan of the (typically) spore-producing phylum Apicomplexa, which is called by some authorities Sporozoa. ... Apicomplexans feed by absorbing either dissolved food ingested by the host (saprozoic nutrition) or the host's cytoplasm and body fluids.Protozoa reproduce asexually by fission, schizogony, or budding. Some protozoa can also reproduce sexually. Relatively few protozoa cause disease

Velocity is The amount of time it takes an object to move from point A to point B. Therefore, option B is correct.

What is velocity?

When an item is moving, its velocity is the rate at which it is changing position as seen from a particular point of view and as measured by a certain unit of time. The meter per second (m/s) is the accepted unit of velocity magnitude (also known as speed). The various forms of velocities include uniform, variable, average, and instantaneous velocities.

There are countless practical uses for velocity, but one of the more frequent ones is figuring out how quickly you (or anything in motion) will get somewhere from somewhere.
