Photosynthesis occurs in both prokaryotes and eukaryotes. How do the locations where photosynthesis occurs differ in prokaryotes
mamaluj [8]

Answer/Explanation:

In eukaryotes, photosynthesis occurs mainly in green plants. These organisms have specialized organelles called chloroplasts that carry out photosynthesis. These contain photoreceptors that absorb photons from the sun through a pigment called chlorophyll, providing the energy to synthesise glucose from carbon dioxide and water.

In contrast, prokaryotes that carry out photosynthesis are able to do so because they have folds in the plasma membrane that permit the attachment of chlorophyll. They do not have specialized membrane-bound organelles like eukaryotes.

An immunoglobulin (Ig) molecule, of any class, with regions symbolized as C or V, H or L , has a light chain made up of _______.
Nadusha1986 [10]

An immunoglobulin molecule of any class with regions symbolized as C or V, H or L, has a light chain made up of one C region and one V region.

The glycoproteins known as immunoglobulins (Ig), often known as antibodies, are created by plasma cells. A number of immunogens, including bacterial proteins, promote B cells' conversion to plasma cells. These cells, which make proteins, are involved in humoral immune reactions to bacteria, viruses, fungi, parasites, cellular antigens, chemicals, and synthetic compounds. Using a B-cell receptor, the immunogen or antigen adheres to the B cells' cell surface (BCR).

As a result, a signal is generated that directs the activation of transcription factors, leading to the manufacture of highly specific antibodies for the immunogen that initially activated the B cell. Furthermore, one B cell clone produces immunoglobulin (specificity). Two light chains and two heavy chains that alternate in a light-heavy-heavy-light pattern make up antibodies, also known as immunoglobulins. Therefore, choice A is the right response.

Red blood cells (a good, colorful example of an animal cell type) when placed in pure water swell up and eventually explode. Why
Snowcat [4.5K]

Answer:

When red blood cells are placed inside pure water they normally swell up and eventually explode. Red blood cells in pure water swell up because the pure water enter in the red blood cells by mean of osmosis. The water molecules are able to enter the red blood cells because the salt concentration inside the red blood cells is more than that of the pure water.

As water continue to move inside the cells, the cell swell up and eventually burst because the internal pressure inside the cell is greater than the external pressure, therefore the cell membrane become ruptured and eventually burst.
