Fundamental elements make the water, air, fire, and earth. Oxygen is one of the six fundamental elements found in living organisms. Thus, option c is correct.
What is the role of oxygen in living organisms?Oxygen is one of the fundamental elements that make the living cell and is essential for aerobic organisms. It is the most crucial element involved in survival, growth, development, reproduction, etc.
It is a vital component of the respiratory, breathing, and the photosynthetic system as it is required as the substrate to produce energy. Oxygen allows the cells to break the sugar into ATP and NADPH molecules.
It is also an important element in circulation to provide energy to the brain and immune cells. It is involved in almost all activities of the living cell.
Therefore, oxygen is the fundamental element for living organisms.

is mitosis or meiosis preceded by interphase?
Answer:
Meiosis is preceded by an interphase consisting of three stages.
Explanation:
The S phase is next, during which the DNA of the chromosomes is replicated. This replication produces two identical copies, called sister chromatids, that are held together at the centromere by cohesin proteins.
Do atoms with more electrons produce more or less spectral lines?
If perfect growing conditions allowed a population of producers to grow and increase in density, which of the following changes in the food web would be expected initially?
A. New populations of herbivores would enter the food web
B. The population size o fab herbivores in the food web would decrease
C. Members of predator populations would leave the food web
D. The population size of predators in the food web would decrease
Answer:
A.
Explanation:
The population of herbivores wouldn't decrease because their food source is being increased. Predators wouldn't leave because more herbivores come to eat the increased number of producers, thus more than likely increasing the number of predators.
Initially, it would be expected that the food web would evolve when new populations of herbivores entered it. So, the correct option is A.
What is Food web?All the food networks in a specific ecosystem make up a food web. Each organism inside an ecosystem is a link in a number of food chains. Energy and nutrients can go along different food chains as their move through the environment.
A food web is created by the linkages between various, interdependent food chains. It involves intricate relationships between producers and consumers. Here, a variety of lower trophic level species are consumed by higher trophic level organisms.
At first, it would be anticipated that as additional population of herbivores entered the food web, it would change.
Therefore, the correct option is A.

Explanation:
You fill a storage cabinet with 12 bottles of normal saline. Each bottle contains 1000 mL. How many ounces of this solution are in the storage cabinet?
Answer:
Answer:amount of solution in the storage cabinet(ounces) ≈ 405.80
Explanation:
You are so h
There were 12 bottles of regular saline in the storage cabinet. Each bottle holds 1000 mL of ordinary saline, so 405.80 ounces of solution are contained in the storage cabinet.
How to calculate the ounces of this normal saline?This suggests that the storage cabinet's normal saline supply is 1000 mL divided by 12 bottles or 12000 mL.
Find the solution's volume in ounces in the storage cabinet, according to the query. As a result, we must convert from milliliters to ounces.
1 mL equals 0.033814022558919 ounces.
12000 = ?
The cross-multiplies
There are 12,000 ounces of solution in the storage cabinet, divided by 0.033814022558919.
405.768270707 ounces of solution are in the storage cabinet.
Therefore, 405.80 ounces of solution are contained in the storage cabinet.

Species that are_______species can occur in the same location and are phenotypically different.
Answer:
Species that are sympatric species can occur in the same location and are phenotypically different.
Explanation:
Speciation is the evolutionary process by which a population of a species acquires differentiating characteristics that lead it to distinguish itself from the species it formed. Sympatric speciation is a type of speciation that consists of the genetic separation of different populations of the same species that live in the same environment (same geographical location), so that species originate by divergence between individuals, that is, they diversify due to to the appearance of isolation mechanisms these can be genetic, ethological or sexual.

What are the features of an energy-requiring reaction? Select all that apply. Small molecules are converted into complex organic compounds. The reaction requires an input of energy. The reaction results in the output of energy. Complex organic compounds are broken down into small molecules.
Answer:
-Small molecules are converted into complex organic compounds.
-The reaction requires an input of energy
Explanation:
Reactions in nature can either be energy-requiring or energy-releasing. Reactions that require energy are called ENDERGONIC reactions i.e. energy is needed to start the reaction provees. They are characterized by the INPUT OF ENERGY.
Also, when small molecules are converted into complex organic compounds by combining together in a process called ANABOLISM, energy is needed to put together the molecules to form a much larger complex molecules. Hence, it is a feature of energy-requiring reactions.
The features of an energy-requiring reaction include 'small molecules are converted into complex organic compounds' and 'the reaction requires an input of energy'.
An energy-requiring reaction is a type of reaction that requires energy, usually in the form of Adenosine Triphosphate (ATP), the energy coin of the cell.Anabolic reactions are chemical reactions that require energy to synthesize complex organic molecules from simpler ones.Conversely, catabolic reactions are chemical reactions that release energy by breaking down large organic molecules into smaller molecules.In conclusion, the features of an energy-requiring reaction include 'small molecules are converted into complex organic compounds' and 'the reaction requires an input of energy'.

What is the advantage to a scientist in using a line drawing rather than a ball-and-stick model or Lewis structure?
Answer:
It saves time
Explanation:
You don't have to draw unnecessary details for complex structures
Line drawings will save the scientist time instead of Lewis structure.
what is Lewis structure ?It is a representation of a molecule structurally, where dots are used to show the position of electron around the atoms and lines represent covalent bonds between atoms.
Lewis structure is used to identify the lone pair of electron in molecules which help to determine chemical bond formation.
Lewis structures is used for the molecule having covalent bonds and for coordination compounds.
It can be also known as Lewis dot diagrams, electron dot diagrams, Lewis dot formulas etc.
This structure are based on the octet rule and describe chemical bonding, do not describe aromaticity, magnetic behavior accurately.
