Answer:

2. Compounds are multiple elements combined in a single molecule.

3. The interactions between the elements in a compound lend to differences in properties than the elements on their own, i.e. boiling point, melting point, mass, volume, etc.

Scientists discovered that the inner core of Earth is a solid. Explain what evidence supports this thinking. Be sure to include
Leya [2.2K]

Answer:

The inner core is solid because the inner core consists of a lot of pressure and high temperatures. And the more pressure and high temperatures the more dense the substance gets.

_____ 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

Why are only inherited traits,not acquired ones,necessary for the process of natural selection?
AfilCa [17]
Aquired traits arent passed onto offspring and natural selection takes place over a long period of time over many generations so only genetic traits can change over a period of time whereas aquired traits, eg a lost limb, are random and one off
