Answer:
The correct answer would be d. mitochondria.
A mitochondrion is a membrane-bound cell organelle involved in the production of energy (ATP) for the cell.
The cardiac muscle or heart muscle is responsible for pumping blood throughout the body and thus, it works throughout life without rest.
The continuous contractions of cardiac muscle need more supply of ATP or energy as compared to any other cell of the body.
Thus, it has a high number of mitochondria so that its high energy demand can be fulfilled.
A defect in the aquaporin molecule would dramatically reduce the rate of diffusion of water across cell membranes.
Aquaporins are a type of protein that form channels in the cell membrane, allowing for the rapid diffusion of water across the membrane. These proteins are essential for the movement of water in and out of cells, and play a crucial role in regulating the balance of fluids in the body. If there is a defect in the aquaporin molecule, the rate of diffusion of water across cell membranes would be significantly reduced, leading to potential problems with fluid balance and cell function.
In summary, a defect in the aquaporin molecule would dramatically reduce the rate of diffusion of water across cell membranes, potentially leading to problems with fluid balance and cell function.

Answer:
Utilize the wall space and have the shop class design & build cubbies to size for the space.
Explanation:
To save on costs, the school could enlist the assistance of one of the technical classes to build the cubbies needs. The best place to build the cubbies would be against the empty wall in the gymnasium.
If the intent of the question is to find a way to build all 50 cubbies, then it may be necessary to try and locate a local supplier that will donate the supplies needed beyond what the budget of $500 can afford to purchase. One way to help offset the cost of the cubbies to incentivize the location by allowing the supplier to place their brand logo on the cubbies somewhere to show local support. Oftentimes, companies will help local schools when they are able to receive a benefit such as advertisement space for the donations.
The school can use a tape measure to determine the dimensions of the storage space and consult with a contractor or carpenter to get an estimate within their budget. Involving the students in the design process can also be beneficial.
The school can find the best solution for designing the storage space by considering the number of cubby holes needed and the budget available. To determine the dimensions of the storage space, they can use the tape measure to measure the size of a cubby hole and multiply it by 50. This will give them the total area required for the cubby holes. The school can then use the masking tape to mark out the dimensions on the empty wall and visualize the layout.
Once they have the dimensions, they can consult with a contractor or carpenter to get an estimate for the cost of materials and labor. They should ensure that the estimate falls within their budget of $500. If the estimate is too high, they can consider alternative materials or designs to lower the cost.
Additionally, the school can involve the students in the design process by organizing a competition or survey to gather ideas for the design. This will not only engage the students but also ensure that the storage space meets their needs and preferences.
