How many times farther from the Sun is Uranus (distance = 19.20 AU) than Saturn (distance = 9.58 AU)?
Answer:
Water is a polar molecule because one area is ________________ and another area is ______________________.
Explanation:
Uranus is approximately 2 times farther from the Sun than Saturn.
What is Uranus?Uranus is a planet in our solar system, orbiting the Sun at an average distance of about 1.8 billion miles (2.9 billion kilometers) or 19.2 astronomical units (AU). It is the seventh planet from the Sun and the third-largest planet in our solar system, with a diameter of about 31,518 miles (50,724 kilometers).
The distance from the Sun to Uranus is 19.20 astronomical units (AU), and the distance from the Sun to Saturn is 9.58 AU. To find how many times farther Uranus is from the Sun than Saturn, we can divide the distance to Uranus by the distance to Saturn:
distance to Uranus / distance to Saturn = 19.20 AU / 9.58 AU = 2.00
Therefore, Uranus is approximately 2 times farther from the Sun than Saturn.

Why does ice have the lowest density?
Answer:
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

Selectively permeable membranes are important in cell function. What makes a membrane selectively permeable?
A.The ability to remove bacteria from the cell
B.The ability to use energy to make proteins used in the cell
C.The ability to modify, sort and package proteins and lipids for storage or transport out of the cell
D.The ability to allow needed materials to enter and wastes to exit as well as the ability to block unneeded materials from entering the cell
The statement that makes a membrane selectively permeable is as follows:
The ability to allow needed materials to enter and wastes to exit as well as the ability to block unneeded materials from entering the cell.Thus, the correct option for this question is D.
What is a Selectively permeable membrane?A Selectively permeable membrane may be defined as a type of membrane that permits the entry of specific substances and the exit of a few substances but significantly prevents the transport of other substances through it.
This action of a selectively permeable membrane protects the cell from any unwanted impurities and damage. It also regulates the balance in the internal environment of the cell by the passage of toxic or unwanted substances outside the cell.
Therefore, the correct option for this question is D.

Gorge and Hattie want to perform a set of experiments to test the optimal water and sunlight levels of a certain species of pea plant.
Gorge decides to test the amount of water that the species needs to thrive. He takes 24 pea plants and separates them into four equal groups and gives each group a different daily amount of water. He keeps all other environmental conditions the same for each group. He measures the initial height of all the pea plants and then measures their growth after one month.
Gorge averages the data from the individual pea plants and comes up with an average for each group, which he reports in the table below.
After Gorge's experiment is complete, Hattie decides to test the optimal sunlight exposure for this species. She takes 24 pea plants and separates them into four equal groups and exposes each group to a differing daily amount of sunlight. She keeps all other environmental conditions the same for each group, including giving each group 15 mL of water daily. She measures the initial height of all the pea plants and then measures their growth after one month.
Hattie averages the data from the individual pea plants and comes up with an average for each group, which she reports in the table below.
Which of the following conclusions can be made based on the results of these investigations?

For any natural ecosystem, which of the following statements applies to the energy pyramid, the biomass pyramid, and the pyramid of numbers? *
1 consumes are at the bottom of the energy pyramid only
2 consumers form the bottom levels and producers are at the top
3 producers at the bottom of the biomass and energy pyramids only
4 producers are at the bottom of all three pyramids as they are the basis of all food chains and webs
Answer:
4
Explanation:
Producers are at the bottom of the energy pyramid because they prove the most energy, they make up most of the population, which is biomass. And the producers have the largest population, which is why they are at the bottom of the pyramid of numbers. Finally they are at the bottom of food chains and webs because they store the most energy inside of them.
