Answer:

A. Sections of DNA that produce proteins that control an organism's characteristics

Explanation:

The other cells need these proteins in order to have a job, but they need to start from genes. Besides human traits, other organelles' dependence on them makes it vital to the life of a cell.

mojhsa [17]

Answer:

Explanation:a) low melting point

Poor conductivity

: Low solubility

Low solubility The mass is equal to the sum of the masses of all the individual atoms in the molecular structure.

b) The cross-sectional area of the fluid.

Therefore The diffusion coefficient is a physical constant dependent on molecule size and other properties of the diffusing substance as well as on temperature and pressure.

A scientist researching salamanders has obtained two different specimens. Under what conditions would he classify them as belong
mafiozo [28]
<span>This is the condition under which he would classify them as belonging to different species - the two salamanders cannot mate to produce a fertile offspring. If these two lizards belonged to the same species, they would normally be able to breed and give birth to a fertile new "child." However, given that they are not of the same species, they cannot do such a thing, which is why this scientist classified them that way.</span>

An actin-binding protein called cofilin binds preferentially to ADP-containing actin filaments rather than ATP-containing actin
Phantasy [73]

Answer:

Cofilin binds to older actin filaments

Explanation:

Microfilaments (also called actin filaments) are a class of protein filament common to all eukaryotic cells, which consist of two strands of subunits of the protein actin. Microfilaments form part of the cell's cytoskeleton and interact with the protein myosin in order to allow the movement of the cell. Within the cell, actin may show two different forms: monomeric G-actin and polymeric F-actin filaments. Microfilaments provide shape to the cell because these filaments can depolymerize (disassemble) and polymerize (assembly) quickly, thereby allowing the cell to change its shape. During the polymerization process, the ATP that is bound to G-actin is hydrolyzed to ADP, which is bound to F-actin. ATP-actin subunits are present at the barbed ends of the filaments, and cleavage of the ATP molecules produces highly stable filaments bound to ADP. In consequence, it is expected that cofilin binds preferentially to highly stable (older) filaments ADP-actin filaments instead of ATP-actin filaments.
