Answer:
The answer is false!
Explanation:
I took the K12 science quiz. I hope this helps! Have a blessed day! :)
The statement "An aquarium with a glass lid is an example of an isolated system" is false as light, air, and heat can transfer through the glass lid.
What is an aquarium?An aquarium is an artificial place that is made for putting fish and other water animals in houses buildings and other places. Aquariums are made up of glass so can we, so we can see the fish's aquarium also have oxygen pumps the water also changed in the aquarium from time to time and. The aquarium is kind of decorative.
Aquariums are made up of glass, and they are open from the top so that fish can get air.
An aquarium is not an isolated system as light year and heat can transfer through the top and fishes are living organisms that need an open system to breathe and live.
Therefore, the statement is false.

Light behaves in specific ways. It can be reflected, refracted, or absorbed, and under certain conditions, run into different kinds of interference. Which explanation best describes why light is refracted as it enters water?
A. The light bends when it enters water due to its reflection.
B. The speed of light remains the same as it moves from air to water, causing the light to reflect.
C. The speed of light increases when it enters a different medium, but it doesn't bend.
D. The speed of light changes as it moves from air to water, causing the light to bend.
Answer:
D
Explanation:
Refraction is generally defined as the change in the direction of a wave as it travels from one medium to another. Light is a form of wave and light refraction is caused by a change in the speed of light as it moves from air to water, causing the light to bend in the process. The medium of travelling has to be transparent.
The change in the speed and direction is due to the variability in the refractive index of media. Light travels faster as it moves from a medium of higher refractive index to a medium of lower refractive index and vice versa.
The correct option is D.
Water has a variety of unique properties, including a low melting point, ability to dissolve other substances, and strong adhesion and cohesion. Which statement is MOST useful for explaining the unique properties of water? A. Water molecules are nonpolar, so a very minimal electrical force attracts them to one another. B. Water molecules may sometimes gain or lose an oxygen atom to become ions, which are held together by ionic bonds. C. Water molecules are held together by hydrogen bonds, which are attractive forces stronger than ionic bonds. D. Water molecules are held together by hydrogen bonds, which are attractive forces weaker than covalent bonds.
Answer:
D. Water molecules are held together by hydrogen bonds, which are attractive forces weaker than covalent bonds
Explanation:
Water is a chemical molecule with unique properties such as a low melting point, ability to dissolve other substances, and strong adhesion and cohesion, as stated in this question. This unique properties can be attributed to the HYDROGEN BONDING that holds the molecules of water together.
However, the hydrogen bonding of water molecules is an attractive force that is quite WEAKER than ionic or covalent bonds but it holds water molecules tightly to one another.

Which statement describes competition within a population?
Several killer whales migrate to a new location.
Two male sea horses fight to win over a female.
Several elk travel together to find and share water.
Different kinds of garden plants take in water from the soil.
Answer:
I think its B if I'm wrong I'm sorry
Two male sea horses fight to win over a female describes the competition within a population. So, the correct option is B.
What is Competition?Competition is defined as an interaction between organisms or species in which both require a resource in limited supply that reduces the fitness of both organisms because the presence of one of the organisms always consumes the available resource which reduces the quantity.
Competition is defined as the fight between different organisms by limited resources. Some examples of interspecific competition between lions and leopards that vie for the same prey and interspecific competition between rice fields with weeds growing in the field, two male seahorses fighting to win over a female.
Thus, the correct option is B.

In the Colorado mountains, three species of bumble bees live in the same habitat. Each species has a different proboscis length: short, medium, or long. Each visits nectar-producing plants that match its proboscis length. This situation suggests that natural selection in the three bumble bee species has resulted in
Answer:
resource partitioning
Explanation:
Resource partitioning can be defined as the division of limited resources that enables species to avoid competition when they live in the same habitat. Moreover, interspecific competition is defined as the competition for limited resources among individuals of different species. In a given environment, species can be competing for essentially the same limiting resources. In the case of the bumblebees, the competence is reflected by differences based on the length of the proboscis (competence for the food), thereby resource partitioning enables species to coexist with one another.

Answer:
local endemics
Explanation:
The most common distribution pattern in species can be considered by their geographical distribution, as different species get distributed as per their climate and the different regions that suit them the most.
What is the significance of the geographical distribution?It is significant because they differ in different parts of the world and provide suitable climatic and other environmental conditions for various animals, plants, and microorganisms to live and evolve. Its significance can be seen in the difference between the life forms in the temperate area and those in the Antarctic area.
Hence, the most common distribution pattern in species can be considered by their geographical distribution, as different species get distributed as per their climate and the different regions that suit them the most.

Describe the net movement of water when a dialysis bag containing a 0.2 M sucrose solution is placed into distilled water, which contains no solutes.
a. There will be no movement of water.
b. Water will move into the bag.
c. Water will move into the beaker.
d. There will be no net movement of water.
Answer:
b
Explanation:
The correct answer would be that water will move into the bag.
The 0.2 M sucrose solution in the dialysis bad has a lesser water potential when compared to the distilled water that has no solutes. By law, water moves from the region of higher water potential to the region of lower water potential. The dialysis bag will, hence, act as a semi-permeable membrane and allow water into the bad from the surrounding distilled water.
