It's function is to provide protection / shelter for different species of fish/water wildlife.It is an ecosystem Which is under water.Corals are marine/ocean invertebrates (without a backbone)Name a process in plants that uses oxygen. Compare the raw materials and products of this process with those of photosynthesis
Answer:
Cellular respiration uses oxygen. Comparisons below in explanation.
Explanation:
Plants do both photosynthesis and cellular respiration. They make their own food (photosynthesis) and break it down to make energy (cellular respiration). Cellular respiration uses oxygen, while photosynthesis doesn't (it is a product).
Photosynthesis has this as its general chemical equation:
[tex]6CO_2 +6H_2O[/tex] ⇒ [tex]C_6H_{12} O_6 + 6O_2[/tex]
Cellular respiration has this as its general chemical equation:
[tex]C_6H_{12} O_6 + 6O_2[/tex] ⇒ [tex]6CO_2 + 6H_2O[/tex]
As you can see, the raw materials of cellular respiration (glucose and oxygen) are the products of photosynthesis. The products of cellular respiration (carbon dioxide and water) are the raw materials used in photosynthesis.

Explain in your own words the difference between a leading strand and a lagging strand.
Answer:
So basically the primary distinction between the leading and lagging strands is that the leading strand is the DNA strand that develops continuously during DNA replication, whereas the lagging strand is the DNA strand that grows in small pieces known as Okazaki fragments. A leading strand is one that is produced in the 5'-3' direction, whereas a lagging strand is one that is formed in the 3'-5' direction. The leading strand is constantly produced where the other is not.

what happens when air masses of different temperatures meet?
Answer: When two air masses meet together, the boundary between the two is called a weather front. At a front, the two air masses have different densities, based on temperature, and do not easily mix. ... Winds are common at a front. The greater the temperature difference between the two air masses, the stronger the winds will be.
Explanation:
Which of the following was developed following Griffith's 1928 experiment. A. Some pathogenic bacteria cannot be heat-killed. Bacterial virulence is related to temperature resistance. B. Streptococcus pneumoniae causes disease. C. DNA from dead encapsulated bacteria can transform living un-encapsulated bacteria into living encapsulated bacteria. D. Dead encapsulated bacteria can cause disease.
Answer:
I believe A is the answer, but I'm not positive.
Explanation:
Griffith demonstrated in 1928 that the ability to synthesis a capsule and consequently become virulent can be transferred from heat-inactivated “smooth” strains to surviving but avirulent “rough” strains of S. pneumoniae. Therefore, option (A) is correct.
What was Griffith's experiment?British bacteriologist Frederick Griffith's 1928 bacteria experiment was the first to demonstrate the "transforming principle," which led to the realization that DNA serves as the carrier of genetic information.
Griffith tried injecting mice with heat-killed S bacteria as part of his investigations (that is, S bacteria that had been heated to high temperatures, causing the cells to die). Unsurprisingly, the mice were not harmed by the heat-killed S bacterium.
The first study demonstrating that bacteria are capable of transferring genetic information through a process known as transformation was conducted by Frederick Griffith.

How does wood that is not burning differ from a nonflammable materials?
Wood is flammable, which means that it can burn when it is exposed to heat, oxygen, and an ignition source (such a spark or flame).
Thus, Nonflammable materials are those that do not readily ignite and do not burn even when exposed to high temperatures or flames.
Combustion Behaviour: During a fire, when wood is exposed to heat and oxygen, a combustion process takes place, releasing heat, light, and numerous combustion byproducts like carbon dioxide and water vapour.
The fire is maintained and can spread as a result of this procedure. Even when exposed to high heat or flames, nonflammable materials do not burn and do not support a fire.
Thus, Wood is flammable, which means that it can burn when it is exposed to heat, oxygen, and an ignition source (such a spark or flame).

Explain how Earth's magnetic field is generated.
Answer:
The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.
Answer:
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet

Which statement can be attributed to the discoveries made by Schwann?
A.All cells come from other cells.
B.All animals are made of cells.
C.All plants are made of cells.
D.
The smallest unit of life is the cell
The statement that can be attributed to the discoveries made by Schwann is as follows:
The smallest unit of life is the cell.Thus, the correct option for this question is D.
What is the contribution of T. Schwann?The major contribution of Theodore Schwann is that he proposed the Cell theory in 1839. This theory consists of three parts. They are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of life for all living organisms. A Cell is the basic structural and functional unit of life.Apart from this, Cell theory was further refined by German Biologist Rudolf Virchow in 1855. He states that "all cells are arising from pre-existing cells". Option one is given by R. Virchow.
While all animals and plants are made up of cells is the second point of the cell theory. So, the correct option with respect to the question is that a cell is the smallest unit of life.
Therefore, the correct option for this question is D.

during osmosis, the net movement of water molecules will be from areas of __ free energy to areas of __ free energy, or __ energetically.
Osmosis refers to the net movement (diffusion) of water molecules across a semipermeable membrane. This movement occurs in favor of a concentration gradient.
During osmosis, the net movement of water molecules will be from areas of HIGH free energy to areas of LOW free energy, or DOWNHILL energetically.Osmosis involves the movement of water molecules in favor of a concentration gradient, i.e., from an area of high concentration to an area of low concentration.Osmosis is a type of passive mechanism because it does not require energy to move water across the membrane.Learn more in:
