What is never found inside the lipid bilateral of a cell membrane

Answers

Answer:

Cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.

Explanation:

Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly. Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids. The passage of these molecules relies on specific transport proteins embedded in the membrane.

Explanation:

Photosynthesis Takes Place in Chloroplasts. ... The inner membrane surrounds a stroma, which is the site of the carbon chemistry of photosynthesis

sorry if im wrong

Photosynthesis occurs in chloroplast thylakoid membranes. Electron transport chains produce ATP and NADPH. Therefore, option (A) is correct.

What are chloroplasts?

Chloroplasts are plastids that are made up of an outer membrane, an inner membrane, grana, and the stroma. These four components make up the chloroplast. The inner membrane encloses a region that is filled with fluid and is known as the stroma. This region includes enzymes that are responsible for light-independent processes that occur during photosynthesis. When this inner membrane is folded inward, it creates linked stacks of disk-like sacs known as thylakoids. These thylakoids are frequently grouped in stacks that are called grana.

The chemical reaction known as photosynthesis, which converts sugar and oxygen from carbon dioxide and sunlight, takes place in chloroplasts, which are found in plant cells.

If an organism is multicellular, it probably has

A.) Prokaryotic cells

B.) Eukaryotic cells

C.) Cancer cells

D.) All of the above

Answers

Answer:

B. Eukaryotic cells

Explanation:

Prokaryotic cells are only seen in unicellular organisms as bacteria and cancer cells are just cells where there has been an error in division or a mutation.

If an organism is multicellular, it probably has - option B.) Eukaryotic cells.

Cells are of mainly two types prokaryotic cells and eukaryotic cells. The main difference between eukaryotic and prokaryotic cells is that:

Eukaryotic cells have a nucleus in which genetic material is stored enclosed by a nuclear membrane.All prokaryotic cells only form single-celled (unicellular) organisms without a true nucleus or membrane-bound structures, examples of prokaryotes are bacteria and archaea. Organisms with eukaryotic cells are called eukaryotes that can be either multicellular such as animals, plants, fungi, and protists, or single-celled as well. So, all multicellular organisms are eukaryotes.

.Thus, If an organism is multicellular, it probably has - option B.) Eukaryotic cells.

Explanation:Make sure u read!!!!

The correct answers are C. Blue light has a longer distance between wave crests than red light, and E. Orange light has a shorter distance between wave crests than violet light.

What is visible light?

Visible light waves are a type of electromagnetic radiation that are visible to the human eye. They make up a small portion of the electromagnetic spectrum and have wavelengths that range from about 400 nanometers (nm) to 700 nm. Visible light waves can be separated into colors of the rainbow, including red, orange, yellow, green, blue, indigo, and violet.

Each color of visible light has a unique wavelength and frequency. Red light has the longest wavelength and the lowest frequency, while violet light has the shortest wavelength and the highest frequency. This means that red light has a longer distance between wave crests than violet light, and violet light has a shorter distance between wave crests than red light.

Answer:

In bacteria cells, you would find pili (only found in bacteria and archaea) and DNA not contained in a nuclear envelope/nucleus. These are, for the majority, exclusively found in bacteria cells.

In animal cells, you would find lysosomes and centrosomes. These organelles are exclusively found in animal cells.

In plant cells, you would find plastids, such as chloroplasts or amyloplasts. More specifically, chloroplasts are exclusively found in plant cells as they are necessary for photosynthesis to occur.
