Answer:
Its isotonic
Explanation:
Because The contact lenses that we wear have been formulated to be isotonic, which means that they have the same osmotic pressure as the tear film in our eye.
Contact lens solution is salty in order to match your tears, which is isotonic to the cells in the eyes. The correct option is C.
What is isotonic solution?Isotonic solutions have the same osmolarity (or solute concentration) as other solutions.
Water will flow in equal parts out of each solution and into the other if these two solutions are separated by a semipermeable membrane.
Isotonic solutions are used to increase fluid volume due to blood loss, surgery, dehydration, and extracellular fluid loss.
The contact lenses we wear are isotonic, which means they have the same osmotic pressure as the tear film in our eye's layer of lubricant bathing the cornea and conjunctiva.
The ocular tissues and the water in the lens must maintain equilibrium.
Thus, the correct option is C.

A strand of DNA has these bases: AGC CAT GTA TAC
What is the complementary DNA strand?
A. ACG GAT CTA TAG
B. TCG GTA CAT ATG
C. TGC CTA GAT ATC
D. UCG CỦA CAU AUG
Answer: The answer is c
Explanation:
DNA replication is semiconservative and at such, complementary base-pairing ensures that if adeinine is found on one strand, thymine is found on the other, and if guanine is found in one strand, cytosine is found on the other. complementary base pairing also helps to hold the double helix together by the formation of hydrogen bonds.
The correct answer is (B) TCG GTA CAT ATG
What is DNA?DNA is a double helix structure with two strands entwined together having complementary base pairs one purine and another for pyrimidine. It has all the required information for protein synthesis.
What is complementary base-pairing?Adenine (A) and Thymine (T) are complementary base pairs and Cytosine (C) and Guanine (G) are also complementary base pairs.
Why other options are incorrect?The option A has adenine as first in the sequence which is not complementary to the one given in the question. The option B had second base pair is guanine which is not complementary to the sequence in questionIn the option D has Uracil as first base pair which is not a part of DNA strand. Uracil is present only in RNA.So, option B is correct with complete complementary sequence of the question.

Diabetes is often suspected when glocose shows up in urine tests. Use the model to explain how glucose could be present in urine. Why do you think this symptoms is especially concerning for young people?
Answer:
In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.
Explanation:
answer for plato, if your gonna use please change the wording, so it sounds like you typed it up instead of coping and paste.
The represented model shows the below mentioned steps:
Step 1: Blood goes to the kidney for the process of filtration and if excess sugar other than normal is present in the blood, the filtered substance will have much sugar as compare to the person who does not have diabetes.
Step 2: The model shows that there is some reabsorption of sugar but there is unusually more amount to filter, some sugar will remain in urine as it passes through the renal tubule to be excreted by the body.
This symptom is required to be concenred because it could create a stress on kidney, which will lead to kidney related problems at young age.
What is diabetes?Diabetes is a disease in which the glucose present in the blood is not converted into glycogen due to less production of insulin hormone.
The main symptoms or early sign of diabetes are feeling hunger and fatigue, dry mouth and itchy skin as well as feeling thirsty other than normal.
Therefore,the represented model shows the below mentioned steps:
Step 1: Blood goes to the kidney for the process of filtration and if excess sugar other than normal is present in the blood, the filtered substance will have much sugar as compare to the person who does not have diabetes.
Step 2: The model shows that there is some reabsorption of sugar but there is unusually more amount to filter, some sugar will remain in urine as it passes through the renal tubule to be excreted by the body.

Which of the following is not one of the four major groups of biomolecules found in living organisms? O carbohydrates O lipids O Phosphoric Acid O proteins
Answer:
Phosphoric Acid is not one of the major 4.
Explanation:
Phosphoric acid is not one of the four major groups of biomolecules found in living organisms. Thus, the correct option for this question is C.
What are Biomolecules?Biomolecules may be defined as those organic molecules which are significantly required in order for the survival of living organisms. This is because these molecules play essential functions like cell division, gradual development, morphogenesis, etc.
The four groups of biomolecules which are found in living organisms are Carbohydrates, lipids, proteins, and nucleic acids. Among which carbohydrates are energy-deriving biomolecules, proteins govern the structural and functional properties of the living cell.
Nucleic acids are responsible for the representation of genetic material and lipids are known for energy storage due to their large simple structure.
Therefore, phosphoric acid is not one of the four major groups of biomolecules found in living organisms. Thus, the correct option for this question is C.
