How do large, mature plant cells compensate for inefficient import and export associated with a lower surface area-to-volume rat

io?
a. Large plant cells have increased lysosomic activity to increase import and export of substances to and from the membrane.
b. Large plant cells have a large water-filled vacuole in the center, decreasing the active cytoplasm volume.
c. Large plant cells have adapted a more efficient metabolic system, whereby fewer nutrients are needed for the structures located at the center of the cytoplasm.
d. Large plant cells maintain a large storage vacuole in the center that stores nutrients for use in the interior of the cytoplasm.

Answer - D. <span>Large plant cells maintain a large storage vacuole in the center that stores nutrients for use in the interior of the cytoplasm.

Reason - Dude really. What are you guys learning in biology LOL. Any ways heres the reason why i chose this answer.

Starting off plant cells of course need storage for variety of nutrients and to store for future use when its needed for the necessary requirements for its survival or growth. Now it Compensates it by having one large vacuole in the middle that takes up roughly 75-80%. Unlike us humans having one in the cell we have it small because its temporary from here to there. But plant cells need it more because they can also store water and as such variety of nutrients. Just like I said before.</span>

Dima020 [189]

Answer:

1. 294N

2. 294N

3. 19.6N

4. 19.6N

5. 4.9N

6. 4.9N

7. 80N

8. 185N

Explanation:

The weight of an object is the force that gravity is having over it, and we measure it in <u>Neutowns (N), which equals Kg x m/s².</u>

To find the weight of an object, we use the formula F= m x g.

F stands for force, m for the object's mass, and g for gravity, which is the force that attracts objects to Earth, and we measure it by the acceleration that an object has during free falling.

<u>The Earth's gravity is 9.8 m/s²</u>

1. We use the formula F=m x g

F= 30kg x 9.8 m/s²

F= 294 N

2. We have to convert the 30000g into kg to use the formula

30000÷1000= 30kg

30000g equals to 30Kg, so the object's mass (m) is 30Kg.

F= m X g

F= 30kg X 9.8 m/s²

F= 294 N

3. F= m X g

F= 2kg X 9.8 m/s²

F= 19.6 N

4.We have to convert the 2000g into Kg.

2000÷1000= 2Kg

The object's mass (m) is 2Kg.

F= m X g

F= 2kg X 9.8 m/s²

F= 19.6 N

5. F= m X g

F= 0.5 kg X 9.8 m/s²

F= 4.9 N

6.We have to convert 500g to Kg.

500g÷1000=0.5Kg

The object's mass (m) is 0.5 kg

F= m X g

F= 0.5 Kg X 9.8 m/s²

F= 4.9 N

7. The gravity on the moon is different from the one on Earth. In the formula, instead of 9.8 m/s² for the gravity (g), we use 1.6 m/s².

F= m X g

F= 50Kg X 1.6m/s²

F= 80N

8. The gravity (g) on Mars is 3.7 m/s², so we have to use it in the formula where it says g to find the object's weight on Mars

F= 50Kg X 3.7m/s²

F= 185 N
