An aquarium with a glass lid is an example of an isolated system.
true
false
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.

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.
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 distribution pattern in species can be considered the most easily measurable
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.

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.

How the coin flip relates to the probability of inheriting genetic condition?
Answer:
A coin represents a diploid, heterozygous cell with its heads and tails sides. The act of tossing the coin to land on heads or tails, provides an apt representation of the segregation of alleles during meiosis in the formation of gametes.
or i guess you could just say its all by chance ;P
peace :)
Answer:
It is very similar to the way traits are inherited in nature, as both combinations occur by chance. Though, in the coin toss, there are only 2 possible alleles whereas in nature there may be more complicated combinations of alleles for traits.

When the speed of the bottle is 6 m/s, the KE is
V 5 kg. m²/s2
Answer: 0.5. 1. 2. 3. 5
Explanation:
When the speed of the bottle is 2 m/s, the KE is These are the responses to the speed question: 0.5, 1.125, 2, 3.125 and, 4.5
What does speed mean?Speed is defined as the distance that is allegedly covered in a given amount of time. It is regarded as the speed at which anything is said to move.
In this instance, speed is estimated as 1/2mv2.
As a result, the variables for calculation are:
If the bottle is moving at 2 m/s, then
= ½ (0.250) (2) ^2
= 0.5
If the bottle is moving at 3 m/s,
= ½ (0.250) (3) ^2
=1.125
If the bottle is moving at 4 m/s, then
= ½ (0.250) (4) ^2.
= 2
If the bottle is moving at 5 m/s, then
= ½ (0.250) (5) ^2
= 3.125
= ½ (0.250)(6)^2
=4.5
Therefore, It is regarded as the speed at which anything is said to move.
