Which of the following most accurately describes what affects Earth's ocean tides?
The Sun and Moon, but the Sun impacts Earth's tides more because it is closer in distance to the Earth.
The Sun and Moon, but the Moon impacts Earth's tides more because it is closer in distance to the Earth.
The Sun and Moon, but the Sun impacts Earth's tides more because it much more massive than the Earth.
The Moon is the only celestial object that influences Earth's ocean tides because it so close in distance to the Earth.
The answer option that most accurately describes what affects Earth's ocean tides is: B. The Sun and Moon, but the Moon impacts Earth's tides more because it is closer in distance to the Earth.
A tide can be defined as the rise and fall of water level in water bodies such as lakes and oceans, especially due to the combined effects of the gravitational force of attraction exerted by the Moon and Sun on planet Earth.
Hence, an ocean tide describes the episodic changes in the height of the surface of an ocean as a result of the gravitational force of attraction exerted by the Moon and Sun on planet Earth.
In conclusion, the Earth's ocean tides is largely affected by the gravitational force of attraction exerted by the Moon than that of the Sun because the Moon is closer in distance to the Earth (approximately 400,000 kilometers).

Is the cholesterol molecule mostly polar or mostly nonpolar?
Answer:
Most of the cholesterol molecule in non-polar and therefore associations with the non-polar fatty acid tails of the phospholipids. However, the hydroxyl group (-OH) on cholesterol carries a negative charge and therefore associates with the polar environment of water either inside the cell or outside.
Explanation:
Mark me brainly please
Answer:
Cholesterol is very non-polar, except for the hydroxyl group attached to the first ring.

Describe why enzymes are important in all living organisms?
Answer:
Enzymes are important because they make the chemical reactions in cells happen quickly.
Enzymes, by speeding up biological reactions, ensure that all necessary activities in a cell can take place simultaneously and prevent one particular activity from overtaking the entire cell or organism. This is possible because enzymes allow chemicals to react more specifically with only certain substances rather than reacting indiscriminately with any number of different substances within cells.
The most famous example of this enzyme effect is when stomach acid reacts with pepsin that turns food into a liquid. The body then uses this liquid for absorption through the intestines where nutrients are then used throughout the body. It's important for people to have enough enzymes in order to digest their food fully however if

Can sunlight change the distribution of traits in a population?(1 point)
No, because the environment can only change behaviors.
Yes, because the environment is the only factor that can change traits.
Yes, because the environment can factor into the distribution of traits.
No, because the environment can only change traits in individual organisms.
A number of factors including environmental factors (for example sunlight) can also play a role in how the traits in a particular population is distributed.
Sunlight can change the distribution of traits in a population because the environment can factor into the distribution of traits.
The distribution of traits is changed when factors in the environment change/evolve and influence natural selection. These environmental factors including sunlight alter the selection of traits passed to generations and can have an effect on the distribution of the traits on Earth.Learn more about environmental factors: https://brainly.com/question/3638961
The sunlight can be a factor for the distribution of traits in a population. Option C is correct.
Natural selection:
It is phenomenon in the evolution in which a population of species in distributed in the habitat or evolve by the certain traits that fits in the nature.
For example-
A population of a species have two types of traits,
1. Individuals that can bear the intense light.
2. Individuals that can not bear the intense light, prefer low light.
After several generation the whole population will divide in the groups according to their ability to bear the intensity of light.
It can also result in the new species that only wake up at night to avoid the sun.
Therefore, the sunlight can be a factor for the distribution of traits in a population.

How do lenses correct vision?
A.) They bend the cornea.
B.) They reflect light away from the retina.
C.) They reflect light towards the retina.
D.) They bend light so that it focuses on the retina.
Answer: D
Explanation:
Glasses correct vision by allowing your eyes to focus light on the correct spot of your retina. The curved frames bend light, and with the right prescription, these frames manipulate the light to reach the correct spot on your retina.
Glasses improve vision by focusing light on the retina. With the right prescription, curved frames bend light to reach the retina.Therefore, option (D) is correct.
What is the function of lenses?Your eyes will be able to focus light on the appropriate portion of your retina when you wear glasses. This will result in improved vision. Light is bent by the curved frames, and when combined with the appropriate prescription, these frames may modify light such that it falls on the retina in the correct location.
Myopia, often known as the inability to see things that are far away, can be rectified with a lens that has a diverging power, which lowers its overall strength. The condition known as hyperopia, in which a person has difficulty seeing things that are up close, can be treated with a lens that converges light in order to boost its power.
