Answer:
1 x 10^13 stadiums will be needed in this scenario
Explanation:
We are told that
1 stadium holds = 1 × 10^5 people and
Number of iron atoms = 1 × 10^18 atoms
If the stadium carries an equivalent number of atoms as that of people.
We can infer that 1 stadium will carry 1 × 10^5 atoms.
The calculation to determine the number of stadiums would then be 1 × 10^18 divided by 10^5 atoms/stadium which was gotten by dividing the total number of atoms by the number of atoms per stadium.
Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium
= 1 × 10^13 Stadiums
This means that 1 × 10^18 atoms would occupy 1 × 10^13 stadiums

How did the development of a waxy cuticle help plants adapt to life on land?
O A. The cuticle minimized water loss from leaves.
B. The cuticle absorbed nutrients from the soil.
C. The cuticle increased photosynthesis.
O D. The cuticle protected reproductive structures.
SUBMIT
Answer:
a
Explanation:
The cuticle in the plants minimizes the water loss or transpiration from leaves. The correct option is A.
What is transpiration?Transpiration is the process by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and moisture from the stem and roots moves upwards or is 'pulled' into the leaves.
The evaporation of extra water from stomata in plant leaves is known as transpiration. It is necessary for some upward movement of water in plants. It aids in the regulation of plant temperature.
To transpire, water vapor must diffuse through this motionless layer from the stomata to the atmosphere, where it will be removed by moving air. The cuticle present in the waxy leaves prevent excess transpiration.
Thus, the correct option is A.

An experiment is carried out to determine how different PH values of soil will affect the growth of tomato plants. In this experiment, the dependent variable could be the
A) height of the tomato plants
B) pH of the soil
C) specific variety of tomato plants used
D) pH of enzymes is tomato leaf cells
Answer:
A. Height of tomato plants
Explanation:
The dependent variable in an experiment is the variable that the experimenter measures or the variable that responds to changes made to the independent variable. The dependent variable is dependent on the independent variable.
In this experiment conducted to determine how different PH values of soil will affect the growth of tomato plants, the growth of the plants is measured by their height. Hence, the dependent variable is the HEIGHT OF THE PLANTS.

Which statement best describes the effect on water transport across the cell membrane if the aquaporin in the figure ceases to function?
Answer:
Water molecules will still be able to move across the cell membrane but at a slower rate.
Explanation:
D isn’t a sensible answer because Aquaporin is a protein with a role to regulate water transport. In its absence, of course there will be defects. And A is impossible due to the existence of active transport. (I also looked it up) (:
Answer:
Water molecules will still be able to move across the cell membrane but at a slower rate.
Explanation:
The aquaporin facilitates water passage, but water can still move across the membrane by osmosis. (osmosis requires no channel protein, but aquaporin makes diffusion faster).

Complete the Concept Map to compare the locations and remodeling functions of osteoblasts and osteoclasts, and explain how hormones and physical stress regulate bone remodeling.
Answer:
The correct answer is attached as an image.
Explanation:
Bone remodeling occurs by the remodeling units osteoblast which is bone deposition and osteoclast which is Bone resorption.
Bone deposition is the process that involves the deposition of minerals in bone tissues which takes place due to the process of osteoblast mainly. the bone deposition is possible in three ways when
- there is an increase in blood calcium.
- there is an increase in mechanical stress.
- decrease in parathyroid hormone
Osteoclast cause the degrade of bone tissue by releasing calcium ion from bone tissue which required opposite conditions than osteoblast that are -
- there is a decrease in blood calcium.
- there is a decrease in mechanical stress.
- increase in parathyroid hormone
A decrease in blood Ca++ concentration causes the parathyroid gland to release PTH, PTH results in osteoclasts to degrade bone tissue which releases Ca++ into the blood. A high level of Ca++, calcitonin results in calcium deposition into the bone.

Bone remodeling involves osteoblasts which is enhances bone deposition and osteoclasts which enhance bone resorption.
What is bone remodelling?Bone remodeling involves the processes by which the bone tissue is remodelled by the action of the osteoblasts which is enhances bone deposition and osteoclasts which enhance bone resorption.
Bone deposition is the process by which bone tissues ate mineralized by means of the osteoblast.
Bone deposition occurs through three possible ways:
increase in blood calcium.increase in mechanical stress, and decrease in parathyroid hormoneOsteoclast are involved in the degradation of bone tissue producing opposing effects to that of the osteoblast as follows:
decrease in blood calcium.decrease in mechanical stress, andincrease in parathyroid hormoneThe parathyroid gland releases PTH in response to low bllod calcium.
PTH induces osteoclasts to degrade bone tissue which releases calcium ions into the blood.
The increase in blood level of calcium ions induces calcitonin to increase calcium deposition in the bones.
