Answer:

The second law of Thermodynamics.

Explanation:  This is because the law states that when energy is transferred (or transformed), more and more of it is wasted.  Like powering a computer, the energy get's lower, and lower as it uses itself to power on the machine.

_____ act as signals or markers to help cells recognize one another.
Varvara68 [4.7K]

Explanation:

-<u>Carbohydrates </u>act as signals or markers to help cells recognize one another.

Carbohydrates are organic macromolecules with a range of functions within organisms. They may act as energy storage, structural support, and signal molecules. Together with transmembrane proteins embedded within the membrane from the extracellular fluid to the cytoplasm, they form glycoproteins (proteins attached to carbohydrates) which function as cell surface markers .

 

Further Explanation:

Carbon, is the backbone of all biological life on Earth. It contains 6 electrons, with 4 on its valence shell, and thus, readily forms covalent bonds with other elements. Covalent bonding involves the sharing of electrons; in nature, this occurs with hydrogen,oxygen, nitrogen, and phosphorus as highly flexible single bonds capable of rotation; rigid, non-rotating  double; and very strong triple bonds. Carbon compounds form rings, and long branched chains- thus, carbon can form macromolecules in nature.

In nature, organic compounds may be large chains of monomers form biological macromolecules which carry out many essential functions in the body. These can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P); they are found in essential organic biomolecules include, proteins, nucleic acids, lipids and carbohydrates.

Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers. Basic makeup: C, H, O -with many polar OH groups

Answer:

more Na+ diffuse into the cell than K+ diffuse out of it

Explanation:

When a nerve cell is stimulated, the electrical properties of the membrane are momentarily reversed. The inside of the membrane attains a positive charge of up to +40 millivolts, while the outside becomes negatively charged. Under these conditions the membrane is said to be depolarized.

During photosynthesis, plants capture light energy and form carbon-containing molecules, such as glucose. Which is not a use for
nlexa [21]

Answer:

During photosynthesis, plants capture light energy from the Sun to break weak bonds in reactants, such as carbon dioxide and water, and form carbon containing molecules, such as glucose. The carbon containing molecules can then be used:

✓ to assemble larger molecules, such as DNA, proteins, and fats.

How does the igneous rock become sedimentary rock? Explain the process.
Vinvika [58]
<span>Igneous rocks, which are formed from cooled magma, are first weathered and eroded into small bits. These small bits, called sediment, will sometimes be carried into rivers and will be cemented and compacted together, forming sedimentary rocks.</span>
