hello, I need some help with this

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

Answer:

Cytosis is is the transportion of large quantities of molecules into and out of cells. If exo means out of, that means the molecules are moving out of the cell. Endocytosis is when molecules move into the cell.

Answer:

I believe it would decrease

Explanation:

The high temperature will be detected by sensors—primarily nerve cells with endings in your skin and brain—and relayed to a temperature-regulatory control center in your brain. The control center will process the information and activate effectors—such as the sweat glands—whose job is to oppose the stimulus by bringing body temperature down.

Answer:

d) By deposition of sediments in a shallow area

Explanation:

Deposition is the deposition of wind, water or ice sediments. The sediment may be shipped in the form of steaks, sand & mud or water-dissolved salts.

Sediment accumulation can be seen everywhere in the water chain, from ponds, reservoirs, deltas and floodplains to high mountain rivers.

Answer:

Describing a trait as dominant does not mean it is the most common; it means that it is expressed over the recessive trait. For example, tongue rolling is a dominant trait, controlled by the dominant version of a particular gene (R). Individuals with one or two copies of R will exhibit tongue rolling.

option B ,is correct answer of this question

Answer:

B

Explanation:

Answer:

Explanation:

Trisodium citrate has the chemical formula of Na3C6H5O7. It is sometimes referred to simply as "sodium citrate", though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart flavor. It is mildly basic and can be used along with citric acid to make biologically compatible buffers

Sodium citrate is chiefly used as a food additive, usually for flavor or as a preservative. Its E number is E331. Sodium citrate is employed as a flavoring agent in certain varieties of club soda. It is common as an ingredient in bratwurst, and is also used in commercial ready-to-drink beverages and drink mixes, contributing a tart flavor. It is found in gelatin mix[clarification needed], ice cream, yogurt, jams, sweets, milk powder, processed cheeses, carbonated beverages, and wine[citation needed], amongst others.

Answer:

The amount of time it takes an object to move from point A to point B.

Explanation:

Can I get Brainliest

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

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.

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

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.
