Answer:Either the cell wall or the membrane
Explanation:
The cell wall proctects the cell while the membrane forms structures inside of the cell
Attached is the exercise. I found the full scheme on the internet.
For the position "a" the correct label is the pink label with glucose concentration low. This type of cotransportation transports two solutes in the same direction, being one in favour of its gradient, and another one against its gradient. In this case the one that's in favour of its gradient is the Na+, so the glucose is in low concentration outside the cell.
For the position "b" the correct label is the one with the glucose and Na+ entering the cell. This is cotransport, done by the glucose-sodium cotransporter.
For the position "c" the correct label is the pink label with glucose concentration high. This type of cotransportation transports two solutes in the same direction, being one in favour of its gradient, and another one against its gradient. In this case the one that's in favour of its gradient is the Na+, so the glucose is in high concentration inside the cell.
For sentence "1." the correct term is "down". Because the Na+ concentration is higher on the outside of the cell, the Na+ moves down its electrochemical gradient.
For sentence "2." the correct term is "against" for the reasons explained above.
Answer:
The benefit is that it makes the organism that has it to be able to convert Acetyl CoA into glucose precursors.
Explanation:
Note that, glyoxylate cycle overlaps the non- decarboxylation reactions of the Citric acid cycle. This can't occur in animals due to the absence of two important enzymes, isocitrate lyase and malate synthase, which are necessary for this pathway.
Some of the equipment the student can use are:
Nets
Underwater cameras
pH indicators
among others.
<h3>What does the student want to study?</h3>
The student wants to find out if there are invertebrates and fish or if the conditions of the pond would support these types of organisms.
<h3>What does the student need to do?</h3>
In this situation, there are two main approaches:
- Study invertebrates and fish: This approach implies finding out if there are already invertebrates and fish in the pond, to do this, the student can
- Directly observe organisms by using a special camera.
- Use a net to catch organisms in the pond and then classify the organisms.
- Study the conditions: This approach implies determining if the pond has the conditions for invertebrates and fish to live. To do this, the student will need to measure conditions such as:
- Nutrients in the pond.
- Temperature.
- Ph.
This will require equipment such as pH indicators.

If the average person blinks 25 times per minute you have to multiply and times it by 60(which is an hour) to equal {1,500} . Next times the number 1,500 by 24 because that is how many hours are in a day so that would equal {36,000} times a day. Now times 36,000 by 7 because that is how many days of the week so {252,000} is the answer per week.
Now to figure out how many times we blink in a year we will multiply
252,000 by 52 because there are 52 weeks in a year.
You get the answer 13,104,000
So you blink 13,104,000 times in a year.
Hope this helps
