Explanation:

a) From the table, the glucose level of person 1 (5.4) was less than the glucose level of person 2 (5.6) after 12 hours of fasting. The glucose level of person 1  falls within the normal fasting blood sugar range (3.9 to 5.6 mmol/L) while that of person 2 was borderline higher than normal.  

b) Also from the table, the glucose level of person 3 (12.1) was greater than that of person 1 (6.4) when the glucose levels were measured 2 hours after drinking 75 g glucose. Normal after-meal sugar level ranges between 6 and 10.9 mmol/L. Hence, person 3 appears to be diabetic while person 1 seems normal.

c) The hormone that person 3 cannot produce is insulin.

Insulin helps lower blood sugar levels when necessary by signalling the liver to convert the excess sugar to glycogen which is then stored in the body. When the blood sugar falls below the normal range, another enzyme, glucagon, signals the liver to convert the glycogen back to sugar to compensate for the decrease.

Answer: A.The population of pink katydids will decrease.

B.The population of green katydids will decrease.

Explanation:

The two statements describe what will eventually happen to the population of the katydids are that:

• A.The population of pink katydids will decrease.

• The population of green katydids will decrease.

This is because from the information given, since birds started feeding on the katydids, this will result in the reduction in the number of katydids. Hence, the decrease in both the pink and the green katydids.

Answer: A: The population of pink katydids will decrease.

C: The population of green katydids will increase.

Explanation: The birds that feed on the Katydids will see the pink ones due to the green ones being camoflauged.  The pink katydids will decrease and the green katydids will increase.

In the given question, 5₹ is the fixed charge and 3₹ is the charge for each extra day.

A fixed charge is a fee or cost that remains constant and does not vary with changes in usage or consumption.

Let the fixed charge for the first three days be x and the charge for each extra day be y.

From the given information, we can set up two equations:

For Saritha: [tex]\rm 3x + 4y = 27 -----(equation 1)[/tex]  

For Susy: [tex]\rm 3x + 2y = 21 -----(equation 2)[/tex]

We can solve for x and y by using elimination or substitution:

Using elimination, we can multiply the second equation by 2 and subtract it from the first equation:

[tex]\rm 3x + 4y = 27[/tex]

[tex]\rm - (6x + 4y = 42)[/tex]

Solving above equations, we get:

[tex]\rm -3x = -15[/tex]

[tex]\rm x = 5[/tex]

Substituting x = 5 into one of the equations, we can solve for y:

[tex]\rm 3(5) + 4y = 27[/tex]

[tex]\rm 15 + 4y = 27[/tex]

[tex]\rm 4y = 12[/tex]

[tex]\rm y = 3[/tex]

Therefore, the fixed charge is ₹5 and the charge for each extra day is ₹3.

Answer:

The correct answer is - natural selection, population.

Explanation:

In this case, the wild bees population experienced a mutation which helps in become more eeficient to fight for nector. This bees population is more sucessful to other that didnt recieved mutation and this mutation as it is adavtageous.

Natural selection always favored beneficial traits for the organisms to eveolved in generation therefore, these population is more succesful and replaced the short winged bees.

Answer:

Cellular respiration depends on two chemical reactants; glucose and oxygen.  Glucose and oxygen are made available to plants and animals for cellular respiration thanks to photosynthesis.  Photosynthesis is the chemical reaction that uses solar energy to convert water and carbon dioxide into glucose and oxygen.  Without photosynthesis, the available glucose and oxygen on the planet would quickly deplete to the point that life could not be sustained on Earth. So the answer would be B :).

Explanation: Hope this helps and good luck :)!

Answer:

Since photosynthesis is the process whereby plant manufacture its own food using a sunlight, so respiration can happen because plant is alive

Answer:

ATP synthase

Explanation:

In both cellular respiration and photosynthesis, the enzyme ATP synthase is utilized to help make ATP.

Answer:

En biología, la hiperpolarización es cualquier cambio en el potencial de membrana de la célula, que hace que esté más polarizada. Es decir, la hiperpolarización es un incremento en el valor absoluto del potencial de membrana de la célula.

During hyperpolarization, sodium ions are pumped out of the cell and potassium ions are pumped into the cell, leading to an overall increase in the negative charge within the cell.

Hyperpolarization is a process that occurs in cells, particularly in neurons (nerve cells). It is characterized by an increase in the negative charge within the cell, which results from the movement of ions across the cell membrane. During hyperpolarization, sodium ions are pumped out of the cell and potassium ions are pumped into the cell. This results in a more negative charge inside the cell, which can inhibit the cell's ability to respond to stimuli.

Hyperpolarization is the opposite of depolarization, which is a process that leads to a decrease in the negative charge within a cell and an increase in the cell's excitability. Hyperpolarization can be triggered by various stimuli and plays a role in the normal functioning of the nervous system.

Answer:

C. They have a greater surface-to-volume ratio.

Explanation:

Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also efficient for these smaller cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.

For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy. So, many small cells have more surface area than one large cell.
