Why are models useful in Earth science?

Biology
2 answers:
solmaris [256]2 years ago

Models are a simplified representation of an object or an idea that describes an event that is too complex, too big or too small to study in real life. These models come in handy when studying geology because scientists couldn't fit the Earth's surface into the laboratory to study it.

What is the primary function of the endocrine system
harkovskaia [24]

Answer:

To maintain body homeostasis

Explanation:

The endocrine system consists of the endocrine glands that release hormones directly int the blood. Those hormones bind to their receptors on the target cells and thus regulate their function. The major glands are:

pineal gland-releases melatonin, controls sleep cycle

pituitary gland-control growth, blood pressure, thyroid glands and metabolism etc.

pancreas-secretes insulin and glucagon, control of blood sugar levels

ovaries, testes-reproductive role (release female and male hormones)

thyroid gland-controls metabolism and protein synthesis

parathyroid gland-controls Ca levels

hypothalamus-connects nervous and endocrine systems, controls other glands

adrenal glands-release adrenalin and steroid hormones.

Most of a cell's molecules can be classified as belonging to one of four major classes: lipids, carbohydrates, nucleotides, or a
goblinko [34]

Answer:

Diagram, in attachments

Explanation:

From the left side of the screen to the right,that is from a structure with a sugar structure with two other molecules  attached to it.

The first molecular structure is Nucleotides. Reasons it contains the middle ribose sugar(5-carbon)connected to the phosphate group and  Nitrogenous bases.This is the structure of nucleotides  and when this is joined by phosphodiester bond between one a nucleotide, to the phosphate group of another  nucleotide molecule  it forms a nucleic acid molecule.

The second structure from left to right with  long carbon chains, it is  a lipid.That js an Ester formed from the reaction of fatty acids with alcohol glycerol.

However, the presence of Phophate group in structure makes it different from a normal tryglycerides.The phosphate group has replaced  one of the  the three fatty acid molecules.Therefore it is called Phospholipid.With one hydropholic ends(phosphate ends) and the hyrophobic end the  carbon chain,with one unsaturated. The lipids molecules are held together my ester bonds.

The next structure is the protein structure(dipeptide).Genrally amino acid is made up of the central Alpha carbon connected on the right by the Carbonyl group(coo-) on the left by the Amine(NH2) group.The R-group which determines the type of amino acids  and hyrdogen atom.In the above structure condensation reaction  has occurred between the hydrogen atom  of  the amine group and carbonyl group of the other amino unit to form a dipeptide.The  bond formed from the condensation is the peptide bond.

The last structure on the far right are the carbohydrate -ring structure and the straight chains.The functional groups of the CHO  -Carbonyl group and hydroxyl group are glues to this.

Select all that apply. Which of the following are not properties of enzymes
AlladinOne [14]
Enzymes are proteins that are biological catalysts

They reduce the activation energy required for a reaction to occur and thus speed up a reaction

Temperature, above a certain point (optimum temperature) causes them to break down and they are gradually destroyed (denaturing)

They work best at a particular pH (optimum pH) and are once again destroyed by low or high pH's

They have a specific shape, with one particular part, known as the active site, that is specific to the substrate they speed the reaction of. These means they are specific to one type of reaction.

They aren't used in the reaction so they're re-usable.

If it isn't one of these then it is not one of the properties of enzymes
