A.exocytosis

B.endocytosis

Answers

Answer:

endocytosis

Explanation:

Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested material.

An amoeba is a single-celled organism that extend their cell membrane around a food particle or prey organism, and the term that best describes the cell process amoebas use to get food is called endocytosis, which is in option B.

What is the significance of endocytosis?

Endocytosis is seen in both the cells of the unicellular eukaryotes and the multicellular cells and by this process, the cells take the food in and use it for many processes, such as in the amoeba, which takes the food in and later uses it for the cellular process. The water intake is seen by the cells and called "pinocytosis," while the removal of the product from the cell is called "exocytosis."

Hence, an amoeba is a single-celled organism that extend their cell membrane around a food particle or prey organism, and the term that best describes the cell process amoebas use to get food is called endocytosis, which is in option B.

Answer:

1. (A) Sea Breeze

2. (C) Uneven heating of earth'S surface

3. (C) Mountain Breeze

Explanation:

Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water.Local winds are caused by unequal heating of Earth's surface within a small area. Local winds form only when large-scale winds are weak. A sea breeze is a local wind that blows from an ocean or a lakeWhen the valley floor warms during the day, warm air rises up the slopes of surrounding mountains and hills to create a valley breeze. At night, denser cool air slides down the slopes to settle in the valley, producing a mountain breeze.

Although the cause of Parkinson's disease is unknown,research indicates that it may be due to defective nuclei in the cells of those affected.Which of these could be studied as a direct result of having defective nuclei and may shed light on the cause of Parkinson

Answers

Answer:

Nervous System could be studied as a direct result of having defective nuclei and may shed light on the  cause of Parkinson .

Explanation:

PASRKINSON DISEASE -: Parkinson's disease is a progressive nervous system condition. Several regions of the brain are affected by the condition, especially an area called substantia nigra that regulates balance and movement.

A trembling or shaking (tremor) of the limb is often the first sign of Parkinson's disease, particularly when the body is at rest. Typically, on one side of the body, the tremor starts, usually in one hand. The head, legs , feet, and face can also be affected by tremors. Other hallmark symptoms of Parkinson's disease are rigidity or rigidity of the limbs and body, slow movement (bradykinesia) or inability to move (akinesia), and impaired balance and coordination (postural instability).

Emotions and thinking ability (cognition) can also affect Parkinson's disease. Psychiatric disorders such as depression and visual hallucinations are created by some affected persons. There is also an increased risk of developing dementia in people with Parkinson's disease, which is a loss in intellectual functions, including judgment and memory.

Hence , the answer is the nervous system and other regions of brain where the disease has a direct result of having a defective nuclei and may shed light on the cause of Parkinson .                      

Which of the following is true of retroviruses? (3 points)
Retroviruses use reverse transcriptase to make viral DNA in a host, and the viral DNA becomes a permeant resident of the host cell.
Retroviruses use DNA polymerase to make viral DNA in a host, and the viral DNA becomes a provirus of the host cell.
Retroviruses use the same machinery as prokaryotes and follow the same process to make RNA.
Retroviruses have an RNA genome instead of DNA but use all of the same enzymes as eukaryotes.

Answers

Answer:

Explanation:

A retrovirus is an RNA virus that is duplicated in a host cell using the reverse transcriptase enzyme to produce DNA from its RNA genome. The DNA is then incorporated into the host’s genome by an integrase enzyme. The virus thereafter replicates as part of the host cell’s DNA. Retroviruses are enveloped viruses that belong to the viral family Retroviridae. A special variant of retroviruses are endogenous retroviruses, which are integrated into the genome of the host and inherited across generations. Endogenous retroviruses are a type of transposon.

What unique features do you notice about the shape of these cells? How might this improve their ability to absorb materials?

RESPOND ASAP

Answers

Need to be able to see the cells to answer the question...

Certain cells need to absorb a lot of materials, such as the cell of the small intestine that reabsorbs the digested foods into the blood. These cells have external growth that facilitates the reabsorption by increasing the surface area.

What is the intestine?

The intestine is divided into two parts, such as the small intestine and the large intestine, The small intestine is responsible for digestion, while the large intestine is responsible for fecal excretion. The enzymes are secreted, complete digestion happens in the small intestine, the digested food is reabsorbed into the blood, and the cells that carry out the reabsorption have external grooves called villi. These villi increase the surface area of the small intestine so that more absorption can occur and cells get enough nutrition for cellular metabolism.

Hence, Certain cells need to absorb a lot of materials, such as the cell of the small intestine that reabsorbs the digested foods, which has villi as a special feature of the cell.

Two unique reproductive adaptations of angiosperms are.

Answers

Answer:

Angiosperms exhibit a vast array of reproducive strategies.

The evolution of several physical and genetic barriers to self-fertilization or fertilization among closely related individuals is thus widespread in angiosperms. A major genetic barrier to self-fertilization is self-incompatibility (SI), which allows female reprductive cells to discriminate between "self" and "non-self" pollen, and specifically reject self pollen.

Explanation:

Two unique reproductive adaptations of angiosperms (flowering plants) are flowers and fruits.

Angiosperms have evolved specialized reproductive structures called flowers. Flowers are composed of several parts, including the male reproductive organs (stamens) and the female reproductive organs (carpels).

They produce fruits, which are structures that develop from the ovary after fertilization. Fruits serve as protective coverings for seeds and aid in their dispersal. They can take various forms, including fleshy fruits like apples and berries, as well as dry fruits like nuts and capsules.

List the four stages of coal formation.

Answers

Answer:

eat, lignite, bituminous, and anthracite.

Explanation:

The stage depends upon the conditions to which the plant remains are subjected after they were buried: the greater the pressure and heat, the higher the rank of coal.

Answer:

There are four stages in coal formation: peat, lignite, bituminous, and anthracite.

Explanation:

Stage one: Peat is the first stage in the formation of coal. Normally, vegetable matter is oxidized to water and carbon dioxide. However, if plant material accumulates underwater, oxygen is not present and so only partial decomposition occurs. This incomplete destruction leads to the accumulation of an organic substance called peat. Peat is a fibrous, soft, spongy substance in which plant remains are easily recognizable. It contains a large amount of water and must be dried before use. Therefore, it is seldom used as a source of heat. Peat burns with a long flame and considerable smoke.

Stage two: Lignite, the second stage, is formed when peat is subjected to increased vertical pressure from accumulating sediments. Lignite is dark brown in colour and, like peat, contains traces of plants. It is found in many places but is used only when more efficient fuel is not available. It crumbles easily and should not be shipped or handled before use.

Stage three: Bituminous Coal is the third stage. Added pressure has made it compact and virtually all traces of plant life have disappeared. Also known as “soft coal”, bituminous coal is the type found in Cape Breton and is our most abundant fuel. It is greatly used in industry as a source of heat energy.

Stage four: Anthracite, the fourth stage in coal formation, is also known as “hard coal” because it is hard and has a high lustre. It appears to have been formed as a result of combined pressure and high temperature. Anthracite burns with a short flame and little smoke.
