Examine the diagram representing a section of an organic molecule.
What process is most directly controlled by this molecule?
A) digestion of nucleic acids
B) regulation of salt levels
C) storage of lipids
D) synthesis of proteins
Answer:
b
Explanation:
The process is most directly controlled by this molecule - D) synthesis of proteins.
DNA The diagram is given is the DNA molecule or sequence which is made of chemical building blocks called nucleotides.These building blocks are made of three parts: a phosphate group, a sugar group, and one of four types of nitrogen bases.To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.DNA contains the instructions needed for an organism to develop, survive and reproduce.DNA sequences must be converted into messages that can be used to produce proteins.Thus, The process is most directly controlled by this molecule - D) synthesis of proteins.

Which is the most exact method of determining the age of geologic features?
Answer:
Radiometric methods
Explanation:
radiometric dating method is the most exact method of determining the age of geologic features. This technique is used in order to find out the age of materials such as rocks or fossils of plants and animals etc. In this method the trace radioactive impurities were selectively incorporated when they were formed. Radioactive elements present everywhere in the universe, these radioactive elements tells us about the age of the rock and fossils present in it.
Which event has been responsible for most extinctions?
A. Asteroids striking Earth
B. The evolution of photosynthesis
C. Rapid changes in climate
D. Sudden volcanic eruptions
The event that has been responsible for the most extinctions in the history of life on Earth is likely rapid changes in climate. Option c is correct.
Throughout Earth's history, there have been numerous instances of dramatic climate change, often associated with shifts in ocean circulation patterns, volcanic activity, or other factors. These shifts have led to periods of mass extinction, during which large numbers of species go extinct in a relatively short period of time.
One of the most famous examples is the extinction of the dinosaurs, which was likely caused by a combination of asteroid impact and subsequent climate change. However, other mass extinctions have been associated with purely environmental factors, such as changes in atmospheric composition, sea level, or temperature. Option c is correct.

What color represents the bonds between the particles of NaC2H3O2?
Explanation:
The picture or the animation is missing. Therefore, it is not possible to represent the color of the bonds between the particles of NaC2H3O2.
However, The compound NaC2H3O2 is a sodium salt of acetic acid called Sodium acetate trihydrate. It is readily formed by the reaction of acetic acid (vinegar) and sodium hydroxide or the carbonates, bicarbonates of sodium.

Answer:
Positive feedback.
Explanation:
When a blood vessel is damaged, platelets attach and recruit more platelets to the area. These new platelets recruit even more, quickly increasing the number of platelets until the damage is sealed with a blood clot. This amplification is an example of positive feedback.
Positive feedback can be defined as the activities of the blood vessels and other organs of the body that enhances, catalyses and accelerates the clotting process until the flow of blood stops eventually.

EXOCYTOSIS
Answer:
Exocytosis: a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.
Explanation:
Exocytosis is the process by which a large amount of molecules are released; thus it is a form of bulk transport. In exocytosis, membrane-bound secretory vesicles are carried to the cell membrane, and their contents (i.e., water-soluble molecules) are secreted into the extracellular environment.

Order the following terms from least to most complex:
Carbohydrates, polysaccharides, atom, monosaccharide, molecule, disaccharide
Answer:
The correct order of these elements from least to most complex is atom → molecule → carbohydrates → monosaccharide → disaccharide → polysaccharides.
Explanation:
Carbohydrates are organic molecules formed by carbon, hydrogen and oxygen, whose complexity is received in the amount of monomers they possess.
According to their level of organization, carbohydrates are constituted by:
Atomic level: atoms of carbon, hydrogen and oxygen.Molecular level: these are the carbohydrate molecules that can be formed, from the simplest to the most complex:Monosaccharides: or simple sugars, such as glucose.Disaccharides: are formed by two monomers. An example of this is sucrose, formed by glucose and fructose.Polysaccharides: formed by chains of more than 2 carbohydrates, such as starch.The term carbohydrate groups all possible forms of these molecules, from the simplest to the most organized molecular.
