Answer:
Water is denser as a liquid than as a solid.
Explanation:
The property of water that makes icebergs float on is due to the fact that water as a liquid is denser than as a solid.
According to the rules of floatation, a less dense substance will always float on a denser liquid because a body will always displace its own weight when placed in a liquid. At room temperature, water as a liquid has a density of 1 g/cm3 but if the same water forms ice, the density would be 0.92 g/cm3. Hence, when ice is placed on water, it will float on it.

Ten fish have lived in a 10-gallon fish tank for 6 months. However, within 2 weeks of adding 6 new fish, the population of fish drops to 7
fish. Which most likely accounts for this drop in the fish population?
A. The additional fish increased the water level.
B. The additional fish reduced the space per fish.
C. The additional fish increased the water temperature.
D. The additional fish reduced the carbon dioxide levels.
Answer:
I think it's D
Explanation:
Although space per fish is important, and may even be correct, I found D to be the most logical answer as each fish would need the same amount of carbon dioxide or the unbalance would cause a decrease in population.

Nitrogen in the atmosphere exists in the form of _____.
NO2
NO3-
NH4+
N2
NH3
Answer:
N2
Explanation:
Although the atmosphere is mostly made up of nitrogen, it is in the form of a gas known as dinitrogen N2. Plants cannot use this form. Dinitrogen, or atmospheric nitrogen, can also be found in the soil. In addition to dinitrogen, other inorganic and organic forms exist in the soil as well.
in cattle, white coat is co-dominant to red coat with a third coat being roan ( red and white). what are the expected phenotypes from a cross between two roan cattle?
Answer:
50/50
Explanation:
Since white and red are co-dominant, they are both just as likely to appear in cattle.

Nemo, a marine fish (adapted for life in the sea salt water ) is placed inside a freshwater aquarium. The next day, the owner finds that he has perished(died) in the tank! Why?
Answer:
The freshwater is hypotonic to the fish
Explanation:
A marine fish is adapted to living in water that is salty.
The fish will not survive because the freshwater would be hypotonic to the body of the fish and as such, excess water would enter its body which will lead to its death. The cells that make up the body of the fish will take-in excess water and lyse, leading to the death of the fish itself.

Why are proteins NOT a primary source of energy in living organisms (carbohydrates are
primary, lipids are energy storage...)?
Answer: Energy Production
The primary role of carbohydrates is to supply energy to all cells in the body. Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Some cells, such as red blood cells, are only able to produce cellular energy from glucose.
Explanation:
what happens during glycosis in cellular respiration
Answer:
In glycolysis, glucose (C6) is split into two 3-carbon (C3) pyruvate molecules. This releases energy, which is transferred to ATP.

A macrophage is a white blood cell that engulfs and digests pathogenic or foreign particles in the body.
An example of this type of cell is shown below. This type of bulk transport that requires ATP is called-
A. Active Transport by Endocytosis
B. Passive Transport by Exocytosis
C. Active Transport by Exocytosis
D. Passive Transport by Osmosis
Answer:
c
Explanation:the transporting is happening outside of the cell
An example of white blood cells such as macrophage, type of cell is shown below. This type of bulk transport that requires ATP is called- A. Active Transport by Endocytosis
Phagocytosis takes place in specialized cells called phagocytes, such as macrophages, neutrophils, and other white blood cells.
Phagocytosis involves the engulfing of large particles.In this cells engulf and digest pathogenic or foreign particles in the body.Phagocytosis is a type of endocytosis.It requires energy that comes from the active transport of a large body of substance inside cells.Thus, An example of white blood cells such as macrophage, type of cell is shown below.

In a healthy ecosystem, which trophic level should
have the most energy? Why? *WILL MARK BRAINLIEST*
Answer:
Producer(plants)
Explanation:
They can produce there own energy and they help all of the other animals stay alive.
in a healthy ecosystem, the trophic level that should have the most energy is the producer.
WHAT IS TROPHIC LEVEL:Trophic level of an organism refers to the position of the organism in the flow of energy in an ecosystem.Organisms feed on one another in an ecosystem to obtain energy needed for their metabolic activities.More energy is contained in lower trophic levels than that of higher trophic levels. This means that, according to this question, more energy will be in the producers as the lowest trophic level.Therefore, in an healthy ecosystem, the trophic level that should have the most energy is the producer.
