The surface of the villi in the small intestine is covered by a single layer of epithelial cells called enterocytes. Enterocytes absorb nutrients from the intestinal lumen as they move up the side of the villus. The enterocytes are shed from the end of the villus through apoptosis after 3 to 4 days. Consequently, new cells must be continuously supplied from the crypt and move up the villus. When a stem cell in the crypt divides, what are its immediate daughter cells

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.

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.

As a conservationist, what are your top three concerns regarding the hydroelectric dam and the biodiversity of the region?

Answers

Answer:

I’m concerned about how the dam will affect the water flow in the river, which can affect the behaviors of fish. I’m also concerned that some fish and aquatic animals might get sucked into the dam. Finally, I worry that the dam could malfunction and cause flooding, which could damage the ecosystem.

Explanation:

Top three concerns regarding the hydroelectric dam and the biodiversity of the region

Hydropower can also cause environmental and social problems. Reservoirs drastically change the landscape and rivers they are built on. Dams and reservoirs can reduce river flows, raise water temperature, degrade water quality and cause sediment to build up. This has negative impacts on fish, birds and other wildlife.

How do hydroelectric power plants affect the environment?

Hydroelectric plants alter the natural habitats of freshwater species in the areas they are located. It changes the concentration of nutrients, water temperature, and the river's flow. Downstream river flow suffers a loss of water and silt loads, reducing water quality.

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.
