brainly Carolus Linnaeus developed a classification system very close to the one that we use today. In particular, we still follow the protocol of giving each unique species a name using binomial nomenclature, a two-word naming system. Which statements describe the major importance of our current classification system
The major importance of our current system of classification is that it helps to correctly identify living organisms.
This is because the classification system gives us information concerning the characteristics of each organism.
What is binomial system of nomenclature?This is the system used in naming living organisms. Every living thing is given two different names:
The generic name
The specific name
The generic name is the name of the genus the organisms belongs to while the specific name is the name of the species to which it belongs.
These two names together ( genus and species names ) are collectively known as the scientific name
For instance:
The scientific name for :
Grasshopper is Valanga nugriconis
Valanga is the genus which grasshopper belongs to and nigriconis is the name of its species
Pineapple is Ananas comosus
Orange is Citrus sinensis
What is classification of living organisms?This is the process of grouping living organisms together based on some unique characteristics

The box on the left has an area of high concentration and an area of low concentration. Scientists would say there is a concentration _____
Answer:
•the air,no longer in contact. •(I'm not sure but I think its )•gradient. a concentration gradient
The molecules in the box on the right are in low concentration gradient. The box on the left has an area of high concentration and an area of low concentration. Scientists would say there is a concentration high concentration gradient.
What is the concentration gradient?
The concentration gradient is the presence of a substance at a specific place. A low concentration gradient means when a substance is dispersed and present far from each other.
A high concentration gradient means when there is a large amount of substance present in a place. These words are used when there is transfer of molecules along the plasma membrane.
Diffusion and osmosis are the two processes by which the transfer of molecules happens.
Thus, a = low concentration gradient., b, = high concentration gradient.

Free fatty acids and monoglycerides are transported across the microvillus with ________________transport and the glycerol by ___________________ transport during the mucosal phase of digestion.
Passive transport is used by free fatty acids and monoglycerides and the glycerol is transported by carrier-mediated transport during the mucosal phase of digestion.
What is cellular transport?It is the movement of molecules between the cell interior and the exterior through the cytoplasmic membrane.
Characteristics of cellular transportPassive transport is one where energy is not required for the substance to cross the plasma membrane, it transports part of the monoglycerides and fatty acids.Active transport is one where carrier proteins must move molecules against a concentration gradient, such as glycerol.Therefore, we can conclude that active and passive cellular transport is the transfer of molecules from one side of the cell membrane to the other.

According to the operon model, for the synthesis of an inducible enzyme to occur, the:.
The operon model explains the regulatory system of the gene expressions in the bacteria. An inducible enzyme will be synthesized if the substrate binds to the repressor. Thus, option B is correct.
What is the operon model?
An operon model is the representation of the genes that are closely related and is the regulation of the genetic mechanism in the bacteria. They consist of the structural gene, an operator, and a promoter.
The inducible enzyme in the operon model is produced if the substrate binds to the repressor. The substrate act like an inducer to promote the transcriptional process by inhibiting the activity of the repressor.
The inhibited repressor will not be able to bind the operator and hence RNA polymerase will be free to move and complete the process of transcription in bacteria and viruses.
Therefore, the substrate binds to the repressor so that an inducible enzyme is produced.

how do eukaryotic cells overcome the problems of finishing replication of dna in the gap left by the rna primer
Eukaryotic cells overcome the problems of finishing DNA replication by ligase enzymes that help to fill the gaps. They are fundamental enzymes during DNA replication.
Ligases and DNA replicationDNA replication is the process by which a molecule of DNA is duplicated in the S phase of the cell cycle.
The termination of this process (DNA replication) happens at the moment that replication forks meet on the same DNA stretch.
Ligases are fundamental enzymes that help to fill the remaining nucleotide gaps generated during DNA replication.

In the past, diabetics used horse or cow insulin
to control their glucose levels. Today, as a result
of genetic engineering, human insulin can be
synthesized by bacteria. State one advantage
for a person with diabetes to receive genetically
engineered insulin rather than insulin taken
from a horse or cow. [1]
Answer:
Genetically engineered insulin is actually human insulin and is less likely to be rejected by the person.
Explanation: Hope this helps
One advantage for a person with diabetes to receive genetically engineered insulin rather than insulin taken from a horse or cow is that human insulin produced by bacteria is less likely to cause an allergic reaction.
Why animal based insulin bad?When animal insulin was used, some people with diabetes developed an allergic response to the foreign protein, causing discomfort and making the treatment less effective. Genetically engineered human insulin produced by bacteria is identical to the insulin produced by the human body, reducing the likelihood of an allergic reaction and making the treatment more effective.
Additionally, genetically engineered insulin can be produced in larger quantities, at a lower cost, and with greater consistency than animal-derived insulin.
