b. The cell selectively filters small nutrients through specialized membrane pores.

c. The cell membrane pinches off to form an extracellular vesicle joined to the cell by filaments.

d. The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it.

e. The cell expends energy to transport materials into the cytosol.

Answers

Answer:

The correct answer is:

The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it.  (d.)

Explanation:

Endocytosis is a type of active transport, where particles such as (large molecules, parts of cells, and even whole cells) are moved into cells.

The various types of endocytosis has a common feature of:

1. invagination of plasma membrane forming pockets around the target particle.

2. the pocket pinches off from original plasma membrane

3. forming a new intracellular vesicle containing the target particle.

The different types of endocytosis includes

a. pinocytosis (cell drinking): takes in extracellular fluids

b. phagocytosis (cell eating): large solid particles are taken in by cells

c. receptor-mediated endocytosis: here, receptor proteins on the cells surface, binds to complementary proteins on the surface of the target particles before endocytosis occurs.

Which of the following statements regarding selenium/selenoproteins is incorrect?

a. They are proven protection against colon cancer.
b. The amount of selenium in foods depends upon the soil where the plants were grown and animals grazed.
c. Selenium functions as an antioxidant.
d. Selenium plays an important role in the regulation of thyroid hormones.

Answers

Answer:

The correct answer is: A. They are proven protection against colon cancer.

Explanation:

Selenium is a mineral that can be incorporated into our bodies in small amounts when we consume certain foods, such as whole grain and dairy products. The amount of selenium in these products depends on the soil where the plants and animals were.

Selenium plays an important role as an antioxidant, which can lower the risk of developing several types of cancer. However, this doesn't mean that its consumption can prevent colon cancer, and the studies that had been done to prove its effectivity in these regards have been inconclusive.

Besides functioning as an antioxidant, selenium also is very important for the regulation of the thyroid hormones, which play an important part in metabolism.

The protein that contains selenocysteine amino acid remnants is called selenoproteins. They are found in the endoplasmic reticulum of the cells.

The incorrect statement is:

Option a. They are proven protection against colon cancer.

The statement can be explained as:

Selenium is a mineral that gets incorporated into our body through foods, dairy and whole grains. The amount of selenium depends on its amount and presence in the soil.

Selenoproteins are good antioxidants that can lower the risks of cancers. But its consumption does not provide complete protection against cancers.

It also regulates the thyroid hormone and plays a vital role in the regulation of metabolism.

Thus, they have not proven medication for colon cancer.

Which feature contains genetic material and is present in a eukaryotic cell but not in a prokaryotic cell?

Which two features are present in a plant cell but not in an animal cell? ************someone HELP PLEASE***********

Answers

Answer:

A DNA is contained in the NUCLEUS of a eukaryotic cell not a prokaryotic cell. Your awnser is " nucleus"

Explanation:

The feature that contains genetic material and is present in a eukaryotic cell but not in a prokaryotic cell is the nucleus. The two features that are present in a plant cell but not in an animal cell are the cell wall and chloroplasts.

1. Eukaryotic cells have a membrane-bound organelle called the nucleus that contains the DNA of the cell. It is in charge of conserving and safeguarding the genetic material, including the chromosomes that contain the genes that govern the properties and operations of the cell.

On the other hand, prokaryotic cells are devoid of a genuine nucleus. The cytoplasm of these cells contains their genetic material, which is normally one circular DNA molecule.

2. Cell Wall: The cell membrane of plant cells is enclosed by a strong cell wall. The plant cell is protected and supported structurally by the cell wall. Together with other polysaccharides, proteins, and cellulose, a complex carbohydrate, it essentially consists of these elements. Animal cells lack a cell wall and are supported instead by extracellular matrix and other structural elements.

Chloroplasts: The chloroplasts found in plant cells are in charge of photosynthesis. Specialized organelles called chloroplasts house the pigment chlorophyll as well as other pigments that are used to absorb light energy.

They do this by converting light energy into chemical energy, releasing oxygen as a byproduct and creating glucose. As animal cells lack chloroplasts, they are unable to perform photosynthesis.

Anaerobic respiration happens in muscle cells and yeast cells.
The equation describes anaerobic respiration in muscle cells.
glucose ---> lactic acid
How can you tell from the equation that this process is anaerobic?
would the answer just be no co2 is produced?

Answers

Answer:

Am I think Co 2 will not be released but rather Glucose will be released

Explanation:

This is because

C6H12O6>2C5H5OH+2Co2 + Energy

there fore glucose is produced

From the equation "glucose → lactic acid," we can infer that the process is anaerobic. One way to determine this is by the absence of carbon dioxide (CO2) in the equation.

Glucose is entirely oxidized to create carbon dioxide, water, and energy during aerobic respiration, which takes place in the presence of oxygen.

Yet, in anaerobic respiration, the lack of oxygen causes an incomplete breakdown of glucose, producing additional byproducts such lactic acid as a result.

Muscle cells have the ability to transition to anaerobic respiration in order to satisfy their energy needs when there is insufficient oxygen.

Muscle cells have the ability to engage in anaerobic respiration, which produces ATP (adenosine triphosphate), the cellular energy currency, by partly metabolizing glucose, during hard exercise or when oxygen supply is constrained.

During anaerobic respiration, lactic acid builds up in muscle cells, which can lead to exhaustion and pain.

Reptiles are a class of vertebrates made up mostly of snakes, turtles, lizards, and crocodilians. The options (A), (B) and (E) are correct.

What are the characteristics of reptiles?

Reptiles, as most commonly defined are the animals in the class Reptilia, a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates and rhynchocephalians.

Moreover, the major groups of living reptiles—the turtles (order Testudines), tuatara (order Rhynchocephalia [Sphenodontida]), lizards and snakes (order Squamata), and crocodiles (order Crocodylia, or Crocodilia)—account for over 8,700 species.

Therefore, the name "reptile" comes from Latin and means "one who creeps". All living reptile species are cold blooded, have scaly skin, and lay cleidoic eggs. They excrete uric acid (instead of urea), and have a cloaca. A cloaca is a shared opening for the anus, urinary tract and reproductive ducts.
