Which substance is coded for by A length of dna?
Yuri [45]

The substance that is coded for by a length of DNA is base. The correct option is A.

<h3>What is a base?</h3>

Nucleobases, also known as nitrogenous bases or simply bases, are nitrogen-containing biological compounds that form nucleosides, which are then components of nucleotides, all of which are the basic building blocks of nucleic acids.

The complete question is attached.

The substance that is coded for by a length of DNA is base.

Thus, the correct option is A.

All of the following are types of passive transport except Group of answer choices facilitated diffusion endocytosis diffusion o
AnnyKZ [126]

Answer:

<u><em>Endocytosis</em></u>

Explanation:

Facilitated diffusion just means that a channel/carrier protein facilitates the transport of the molecule. It goes along the concentration gradient.

Diffusion is simple passive transport/simple diffusion. Only small nonpolar molecules can do this.

<u><em>Endocytosis is a type of bulk transport. It is when macromolecules are brought into the cell. This is a type of active transport because it requires energy to do.</em></u>

Osmosis is specifically used for water, and water is a small, nonpolar molecule. In a phospholipid bilayer/cell membrane, aquaporins (a protein) are used to facilitate transport across the membrane. Fun fact: Reverse osmosis is used to desalinate salt water. They basically push water through a man-made membrane that will only allow water to pass through.

Overall, passive transport is along the concentration gradient, while active is against it (going along the concentration gradient means if there is more of one molecule on one side of a membrane than the other, the molecule on the higher side will go towards the lower side)

I learned this in respect to a phospholipid bilayer. If you need a further explanation on any of this lmk.

Match the call structure with the best description. Each cell structure matches with exactly one description.
Makovka662 [10]

Answer:

Please find the cell structure with their best descriptions below

Explanation:

1. Capsule: Capsules are one of the Glycocalyx that firmly attaches to the cell surface and helps the cell avoid phagocytosis.

2. Slime layer: Slime layer is the other Glycocalyx that is loosely attached to the cell surface and helps the cell prevent dessication.

3. Flagella: The flagella is a long whip-like cell structure found in bacteria and some protists and principally used for moving.

4. Conjugation pilus: Conjugation pilus is a cell structure in bacteria that is used to transfer DNA to another bacteria cell.

5. Fimbriae: Fimbriae is a short, bristle-like protein that project from cell surface and help cells attach to surfaces of other cells.

6. Cell wall: Cell wall is a cellular structure found in plant cell and bacteria cells, whose function is to protect cells from harsh conditions and helps maintain cell shape.

7. Cell membrane: The cell membrane controls passage of substances into and out of the cell.

8. Cytoplasm: The cytoplasm is a gelatinous material found inside the cell.

9. Inclusions: Inclusions are structures in cells that formed from the deposits of nutrients.

10. Endospores: Endospores are structures that protect bacterial genome in a dormant state under adverse environmental condition.

11. Ribosomes: Ribosomes are organelles in a cell that makes polypeptide (protein).

12. Mycolic acid: Mycolic acid is a waxy molecule (long fatty acid chain) that is found in some gram positive bacteria and associated with their cell wall.

13. Nucleoid: A nucleoid is a region in prokaryotic cell where chromosomal DNA and DNA-associated proteins are concentrated.

14. Pili: Pili is similar to the Fimbriae but longer and contain less numerous protein appendages than fimbriae used in attachment.
