Answers:

The importance of DNA copying in reproduction is Organisms look similar because their body designs are
similar. If body designs are to be similar, the blueprints for these designs should be similar. Thus, reproduction at its most basic level will involve making copies of the blueprints of body design. The chromosomes in the nucleus of a cell contain information for inheritance
of features from parents to next generation in the form of DNA (Deoxyribo Nucleic Acid) molecules. The DNA in the cell nucleus is the information source for making proteins. If the information is changed, different proteins
will be made. Different proteins will eventually lead to altered body designs.
Therefore, a basic event in reproduction is the creation of a DNA copy. Cells use chemical reactions to build copies of their DNA. Thiscreates two copies of the DNA in a
reproducing cell, and they will need to be separated from each other. However, keeping one copy of DNA in the
original cell and simply pushing the other one out would not work, because the copy pushed out would not have any organized cellular
structure for maintaining life processes. Therefore, DNA copying is accompanied by the creation of an additional
cellular apparatus, and then the DNA copies separate, each with its own cellular apparatus. Effectively, a cell divides to give rise to two cells.

These two cells are of course similar, but are they likely to be absolutely identical? The answer to this question will depend on how accurately the copying reactions involved
occur. No bio-chemical reaction is absolutely reliable. Therefore, it is only to be expected that the process of copying the DNA will have some variations each time. As a result, the DNA copies generated will be similar, but may
not be identical to the original. Some of these variations might be so drastic that the new DNA copy cannot work with the cellular apparatus it inherits. Such a newborn cell
will simply die. On the other hand, there could still be many other variations in the DNA copies that would not lead to such a drastic outcome. Thus, the surviving cells are
similar to, but subtly different from each other.

Answer:

Energy

Explanation:

Energy from the wind transfers to the water as the water moves toward land. Like all waves, water waves only transport energy. They move only through matter, so water waves are mechanical waves.

Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How does f
malfutka [58]

Answer:

By lowering the levels of total cholesterol and low density lipoprotein (LDL)

Explanation:

Dietary fibers are classified into two: the soluble fiber and the insoluble fiber. Studies have show that the soluble fiber play a significant role in lowering blood cholesterol, hence reducing the cardiovascular diseases.

Soluble fiber helps to lower blood cholesterol by its ability to bind to the small intestine which further binds to cholesterol most especially the ad cholesterol (low density lipoprotein). Binding of Fibers to cholesterol prevents them from migrating to the blood stream and to other  parts of the body. Since cholesterol can't get into the bloodstream, it exits the body through feces. Fiber has more effect on lowering LDL (bad cholesterol) than High density lipoprotein (good cholesterol.

What kind of phytoplankton is noctiluca
lesantik [10]
Noctiluca scintillans, commonly known as the sea tinkle and also published as Noctiluca miliaris, is a free-living, nonparasitic, marine-dwelling species of dinoflagellate that exhibits bioluminescence when disturbed (popularly known as mareel). Its bioluminescence is produced throughout the cytoplasm of this single-celled protist, by a luciferin-luciferase reaction in thousands of spherically shaped organelles, called scintillons. Nonluminescent populations within the genus Noctiluca lack these scintillons.
