Answer:
24 hours and 37 minutes
Explanation:
At Mars' orbital speed of 24 km per second, it takes the planet 24 hours and 37 minutes to complete one rotation. That is just a little more than a day on Earth.
Answer:
The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.
An egg is protected by its outer shell. However, the shell also allows moisture and air to pass through. Which cell structure performs a similar function? A. cell membrane B. cytoplasm C. nucleus D. vacuole
Answer:
A. Cell membrane
Explanation:
The cell is the basic unit of the living organisms. The cell consists of the various cell organelles like nucleus, mitochondria and Golgi. The cell membrane covers the cell boundary.
The outer shell protects the egg and allows the exchange of moisture. The plasma membrane performs the similar functions ad allows the transport of some selected particles only.
Thus, the correct answer is option (A).
Answer:
A. cell membrane

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.

How are rainbows made?
Answer:
Explanation:
The sun makes rainbows when white sunlight passes through rain drops. The raindrops act like tiny prisms. They bend the different colors in white light, so the light spreads out into a band of colors that can be reflected back to you as a rainbow.

The glaciers are visible because Ice floats when it freezes .This particularly helpful to life as it insulates the water below and is home to a variety of animals. Which is property of water is the reason that we can see icebergs float
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.
On what day did the Paramecium aurelia population reach the carrying capacity of the environment? How do you know?
Cells sometimes use passive transport to move molecules across their membranes. The rate at which a cell engages in passive transport is determined by —
the amount of energy that the cell generates.
the composition of the cell membrane.
the size of the cell's chloroplasts.
the number of vacuoles that the cell contains.

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!

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.

Explanation:
Jonathan designed an experiment to plant lima bean seeds. His variable was to change what kind of light each plant received. He
used a different kind of light with each plant. He hypothesized that the plant grown under the plant light would have the greatest
amount of growth. Did the data support the hypothesis? Explain.
Answer:
Yes, it was.
Explanation:
The data did support the hypothesis because the data given was generalized on the change of light each plant received. The hypothesis was that the plant light would have the greatest amount of growth. The data was the different light types and the hypothesis was which one he inferred would work best.
Answer:
- The type of plants used in the study
- The number of plants in each experimental group
- A complete citation of the source

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.
