The molecules in the box on the right are in _____
The box on the left has an area of high concentration and an area of low concentration. Scientists would say there is a concentration _____
Answers
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.

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
Answers
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

Answers
Answer:.nitrates
.ammonia
.proteins
. ammonium salts
Explanation: the variations of the nitrogen bases are: [tex]NO3[/tex] (nitrate), which is found in the plant nodules that we feed on,
.Ammonia, which is excreted by us through urines, which also contains nitrogen, which when absorbed into the soil, form ammonium salts
.proteins, that we get when we feed on nitrogenous foods, which when we die they get decomposed into nitrates and ammonia.
.ammonium salts, teat are changed by the nitrifying bacterias into nitrogen gas which returns back in the atmosphere
.
The four nitrogen bases contribute to the variation between humans because the order of nucleotides determines phenotypic features associated with genetic inheritance.
In DNA, there are four types of nucleotides, each containing one different nitrogen base.The four nitrogen bases in DNA nucleotides are Adenine, Guanine, Cytosine, and Thymine.The linear order of these nucleotides in genes largely determines the phenotypic features associated with genetic inheritance.In conclusion, the four nitrogen bases contribute to the variation between humans because the order of nucleotides determines phenotypic features associated with genetic inheritance.

Secretory proteins are:____.
a. produced by ribosomes on the smooth endoplasmic reticulum.
b. chemically modified in the nucleus.
c. produced by the cell for internal use.
d. released from the cell through the plasma membrane.
Answers
The correct answer is Secretory proteins are produced by ribosomes on the smooth endoplasmic reticulum.
What are secretory proteins?Secretory proteins include both endocrine and exocrine proteins that are secreted by cells. Secretory proteins are found in a wide variety of hormones, enzymes, toxins, and antimicrobial peptides. Protein secretory molecules are created by the endoplasmic reticulum.
An average of 3-5 amino acids are produced by ribosomes at the cytosolic face of the ER in mammalian cells every second.
The intestinal epithelium is composed of the enteroendocrine, Paneth, goblet, and absorptive enterocyte cell lineages as well as three other types of secretory cells. The fifth and least typical type of intestinal cell is called a tut cell.
Hence, the correct answer is Secretory proteins are produced by ribosomes on the smooth endoplasmic reticulum.

Answers
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.
