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.

Name 2 body systems that interact to maintain
homeostasis in the human body and explain how they do
Answer:
Internal Temperatures
Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin's surface.
OR,
The nervous and endocrine systems exert the ultimate control over homeostasis because they coordinate the functions of the body's systems. Regulation of body temperature, blood pressure, pH, and glucose concentration are four examples of how the body maintains homeostasis.

•Lithosphere:
•Asthenosphere:
•Mesosphere:
Answer:
lithosphere
Explanation:
is up of brittle crust and the top part of upper mantel and also the coolest and most rigid part of the earth
Answer:
Lithosphere:
The lithosphere is the rigid outermost layer of the earth known as the mantle and the crust. And it is defined by its rigid mechanical properties.
Asthenosphere:
This layer is highly viscous and is very mechanically weak and is located below the Lithosphere it is also known as the ductile region of the upper mantle.
Mesosphere:
The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.

All living things need energy to survive. The most common source of energy for organisms is glucose molecules, which are used as food. A plant’s food is no exception. Where do plants get the carbon needed to make glucose molecules during the process of photosynthesis?
from the ground.
from the air.
from the water.
from the sun.
Answer:
the air
Explanation:
Plants get the carbon from the air which are needed to make the glucose molecules during the process of photosynthesis in plants. Thus, the correct option is B.
What is Photosynthesis?Photosynthesis is the process of formation of carbohydrate (sugar) in the green leaves of plants. This process takes place in the presence of light. In this process, the light energy (solar radiation) is trapped in the chlorophyll pigment present in the green leaves of plants, this energy is converted into chemical energy in the form of glucose (carbohydrate) which is used by the plants in various processes.
The reaction includes the reaction between carbon dioxide and water molecules which are present in the air to produce glucose and oxygen gas which are consumed as food and in the process of respiration.
Therefore, the correct option is B.

From which hot spot would you view Polaris at an altitude of 45 degrees?
Answer:
Massena, New York
Explanation:
Polaris is most popularly known as the North star. It is also famous by the name of "Pole Star". It is the closet to the north celestial pole. At present it is the northern pole star currently.
It is found in the constellation of Ursa Minor. It is the one of the brightest star seen in the night sky. It is considered the star of the second magnitude which is situated close to the heaven's north pole.
The altitude of the Pole star or the Polaris when an observer is at the Tropic of Cancer is measured at 23.5 degree. While if the observer sees the Pole star at its zenith, the observer is located at the North Pole. i.e. 90 degree.
And the spot from where the observer views the Polaris at 45 degree altitude is Massena, New York.

What important soil function does soil structure influence ?
Answer:
A good soil structure is important to allow air and water into the soil which are vital for healthy plant growth. It will improve drainage and reduce soil erosion caused by excess surface run-off. Without structure, soils will suffer from anaerobism, waterlogging and nutrient lock-up and, ultimately, plants will die!

In your opinion, what are the three most important molecules needed for the production of ATP? Explain your reasoning.
To produce the energy required to drive ATP synthesis, the human body requires three different types of molecules: lipids, proteins, and carbohydrate.
What molecules are required for the production of ATP?
In the mitochondria of a cell, the process of cellular respiration also results in the formation of ATP.
This can be done through either anaerobic or aerobic respiration, depending on whether oxygen is present.
ATP is produced during aerobic respiration from glucose and oxygen, along with carbon dioxide and water.
ATP hydrolysis provides the energy needed for many essential processes in organisms and cells.
These include intracellular signaling, DNA and RNA synthesis, Adrenergic signaling, synaptic signaling, active transport, and muscle contraction.
Therefore, lipids, proteins, and carbohydrate are important molecules in production of ATP.

Organize the parts of this body system in the CORRECT order (starting with is organism level) according to levels of organization in a multicellular organism
Answer:
neurons - nerve tissue - brain - central nervous system - human being.
Explanation:
Reason: The Levels of Organization is organizing how everything in a human body is put together. Example: Neuron (or cell), tissues (that are made from cells that come together), heart (is created when groups of tissues come together), circulatory system (is made when other groups of organs come together to form a system that work with each other to maintain life), and then the is carries on with other systems that together form the human body
The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.
What do you mean by levels of organization?Biological organization is the hierarchy of complex biological structures and systems that define life using a reductionistic approach. The traditional hierarchy, as detailed below, extends from atoms to biospheres.
The scientific study of the different levels of organization of living beings, helps us gain an insight into the complexities of their structure and functioning. Every organism on Earth, from the smallest to the largest one, follows this establishment.
Using the circulatory system as an example, a cell in this system is a red blood cell, the heart's cardiac muscle is a tissue, an organ is the heart itself, and the organ system is the circulatory system. An organism is made up of four levels of organization: cells, tissues, organs, and organ systems.
