Lipids are the class of biomolecule in the table. Thus option C is correct.
What are different types of biomolecules ?
Biomolecules are major building blocks of all living organisms which includes Carbohydrates, Proteins, Fats, Nucleic Acids and the basic components are carbon, hydrogen and oxygen atom.
Carbohydrates are polyhydroxy aldehydes or ketones collectively called as saccharides or sugar; It can be up different types monosaccharide, oligosaccharide and polysaccharides based on composition of number of sugar molecule.
Proteins are polymers of amino acids which are joined by peptide bond and form polypeptide, can be classified as primary, secondary, tertiary and quaternary protein.
Nucleic acids are the carrier of genetic material can be up two types such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), made up of nitrogenous base, sugar and phosphate.
Lipids are organic water insoluble biomolecule related to fatty acids, they include sterols, mono-, di- or triglycerides, phospholipids, etc.
Thus option C is correct.

What is the name of the organic molecule modeled below? A propane B propene C propyne
The given organic molecule is the structure of propene. The given molecule has a single double bond. Hence, Option B is the correct answer to the statement.
How is nomenclature done?The organic molecule nomenclature is determined by the presence of a single bond, double bond, or triple bond. The functional group has an important role too.
The single carbon is called mono. if two carbons are present, the compound is called di. if three carbons are present, the compound is called prop. In the given molecule, there are three carbons.
If a single bond is present, that bond is called "ane." If a double is present, it is called "ene". "Yne" is called when three bonds or triple bonds are present. By combining the carbon number and the bond, the nomenclature is complete. Here, three carbon molecules are present with a double bond; hence, it is called propene.
Hence, the correct answer is option B, which is propene.

La Rafflesia arnoldii es una planta tropical con una enorme flor rojo-sangre, que emite calor y despide olor a carne descompuesta. ¿para qué le sirven a esta planta estas adaptaciones?
Answer:
Rafflesia arnoldii is a tropical plant with a huge blood-red flower, which emits heat and emits the smell of decomposed meat. What use are these adaptations to this plant
Explanation:
The smell is adaptation for pollination.This is because it attracts insects which carry on the process of pollination.
Its possible Endothermy characteristic is for mimicry Its releases heat to attract the pollinators- blowflies.The endothermic mechanism is well pronounced during flora development: which further buttress the fact that this is related to pollination to attract blowflies, and not to thermoregulation.

The expansion of the ranges of tropical fish was most likely caused by-
A. agricultural runoff that contributes to dead zones in the ocean
B.global droughts that raise the salt concentration of ocean waters
C.the rising temperatures of ocean waters
D.acid rain pollution that lowers the pH of ocean water
Answer:
C
Explanation:
The expansion of the ranges of these fish was most likely caused by the rising temperatures of ocean waters. This is because these types of fishes live in both fresh-water and salt-water but only in aquatic tropical environments around the world. The increase in temperatures of ocean waters has provided more suitable habitats for these fishes to expand to.
Harvey mixes two liquids. Which observation of the new mixture most likely indicates a precipitate is forming? a cloudy appearance a bubble formation a change in color a change in odor
The appearance of a precipitate in an aqueous phase reaction is easily signaled by a cloudy appearance of the reaction mixture.
A precipitate is formed when reaction between two aqueous reactants yields an insoluble product. That insoluble product is referred to as a precipitate. Usually precipitates are formed during double decomposition reactions.
When a precipitate is formed, we can easily observe it from a cloudy appearance of the reaction mixture.

Continents are found in the continental crust. True or false?
Answer:
true (more info below)
Explanation:
The continental crust is a sheet of granite, sedimentary and metamorphic rocks that surround the continents and the shallow seabeds near their coasts, known as the continental shelves. This is less thick than the substance of the mantle of the Planet, which therefore "floats" on top of it.

When listing the levels of organization in organisms from least complex to most complex, which level is just below organs in complexity?
Answer:
Tissue
Explanation:
Multicellular organisms are complex and every complex organism consist of building blocks. This is the case in the level of organization in living organisms. All living organisms are made up of CELLS. In multicellular organisms i.e. more than one, the cells that perform a similar role come together to form the TISSUE.
Tissues with similar function together forms the ORGAN. Organs that perform similar functions collectively makes up ORGAN SYSTEM. Based on this, the level of organization moves from the least complex "cells" to most complex "organ systems".
The order is as follows:
Cell-----> Tissue-----> Organ-----> Organ systems

Why doesn’t urine flow back to the ureters?
Answer:
With vesicoureteral reflux, urine flows backward from the bladder, up the ureter to the kidney. It may happen in one or both ureters. When the "flap valve" doesn't work and lets urine flow backward, bacteria from the bladder can enter the kidney. This may cause a kidney infection that can cause kidney damage.

A community structure is define by the diverse organism present and the various number of species.
A community requires both biotic and abiotic factor to form a good structure.
Base population is needed - this are the primary producer, that transfer energy to other organism in the environment. The produce their food themselves.
Consumers - consumers feeds on producers, herbivores animals feeds on producer/plant while carnivores feeds on herbivores. Energy is then transfer when they chemical reaction takes place via the food comes
Decomposer - They act on the dead and remains of plant and animal. They help release nutrient back into the soil. Example of decomposer is earth worm.
