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.

Describe complementary base pairing between DNA with DNA and DNA with RNA
Answer:
Complementary base pairing between DNA and DNA consists of the way in which one DNA strand binds to another, by linking a pure base to a pyrimidine. Complementary base pairing between DNA and RNA occurs during transcription, where from the nitrogenous bases of the template strand, complementary nitrogenous bases are added to the RNA.Explanation:
The complementarity of nitrogenous bases consists of the union of a purine base and a pyrimidine base, allowing the bonding between two strands of a nucleic acid.
In DNA the purines are adenine (A) and guanine (G), while the primidines are cytosine (C) and thymine (T).
In RNA the purines are adenine and guanine, the pyrimidines being cytosine and uracil (U), since thymine is not found in RNA.
Adenine is complementary with thymine, or with uracil, forming a double hydrogen bond. Cytosine is complementary to guanine and forms a triple hydrogen bond.DNA with DNA DNA with RNA
A=T A=U
C≡G C≡G
Base pairing in DNA —DNA with DNA— is important in holding its two strands together, as well as in the replication process, which is carried out according to base complementarity.
DNA-RNA base pairing is observed during transcription where a purine base from the DNA template strand allows the incorporation of a pyrimidine into RNA, while a pyrimidine from DNA is complemented by a purine in RNA.
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 ofMultiple Choice
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.

True or false: the sound of your heartbeat is caused by the heart valves opening and the chambers filling with blood
Answer:
Explanation:
The sound of a heartbeat is caused by the heart valves opening and closing as they pump blood. When the heart is working properly, blood can only flow in one direction. The valves make this possible by opening and closing in exact coordination with the heart’s pumping action

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.

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.
Using relative dating, could a scientist determine whether C. amphibius or C. rapidus is older? Support your claim with scientific reasoning.
Answer:
Yes.
Explanation:
Yes, with relative dating, a scientist can determine whether C. amphibius or C. rapidus is older because relative dating provides information about the formation or presence of a material or organisms. Relative dating refers to the process of determining or finding if one rock or geologic event is occurring earlier or later than another or if one object such as rock or geologic event is older or younger than another. So by using relative dating we can find out which one is older, whether C. amphibius or C. rapidus.
Scientists can determine whether C. amphibius is older than C. rapidus, and vice versa, using relative dating.
We can arrive at this answer because:
Relative dating has the ability to place past events in a relative order, close to reality.This allows the age of a fossil, or an object, to be compared to the age of another object.In this case, the relative dating does not show the absolute age of the objects, but allows obtaining an approximate age, scientifically accepted and proven.This allows scientists to estimate which fossil is older than the other.
