Answer:

The organism closest to the coral snake is organism 3, followed by organism 1 and finally organism 2.

Explanation:

The more similar the DNA composition of the organisms, the closer and more closely related they are. With that we can say that the coral snake is closer to organism 3, since the sequence of nitrogenous bases in its DNA is more similar, in relation to other organisms. After organism 3, it is organism 1 that most resembles a coral snake. Organism 2, however, has a different DNA composition, the organism being less similar and the more distant from the coral snake.

Mazyrski [523]

The right answer is tracheids allow for efficient transport of water over longer distances.

Tracheids are conduits for the transport of raw sap (composed of water and mineral salts) to vascular plants. They are composed of a series of elongated cells. During the formation of tracheids these cells die, are emptied of their contents and are fused vertically to form a hollow conduit. The tracheids are located in the xylem, plant tissue allowing the transport of raw sap. Derived from the primary xylem (protoxylème), they have a role in the overall support of the plant.

In addition to tracheids, angiosperms possess vessel elements for transporting raw sap.

How does light intensity affect oxygen production?

ZanzabumX [31]

Greater light intensity would mean a faster rate of photosynthesis in plants. photosynthesis takes in carbon dioxide and water to produce glucose and oxygen. therefore, a greater light intensity would mean faster oxygen production

Biological augmentation is a process that _________. answer correct uses organisms to detoxify polluted ecosystems use organisms

nikdorinn [45]

Biological augmentation is a process that uses organisms to add essential materials to a degraded ecosystem. It involves the addition of archaea, or bacteria cultures required to speed up the rate of degradation of a contaminant, this is supplementation application of non-toxic, natural, beneficial microbes, enzymes and minerals to enhance the rate of degradation.

The major difference between starch, glycogen, and cellulose and their adjacent glucose subunits is the ________.

sveta [45]

Answer:

Starch is the storage form of glucose (energy) in plants and the glucose molecules are linked by alpha 1,4 glycosidic linkage.

Cellulose is a structural component of the plant cell wall and glucose molecules are linked by beta 1,4 glycosidic linkage.

Glycogen is the storage form of glucose (energy) in animals and glucose molecules are linked by alpha 1,6 glycosidic linkage.

Explanation:

All of these sugars are polysaccaride sugars containing large number of glucose subunits.

Starch is a polysaccharide extracted from agricultural raw materials. It contains amylose and amylopectin. Amylose is an un-branched chain polymer of D-glucose units while amylopectin is a branched chain polymer of D-glucose units.

Glycogen is the storage form of glucose in animals, It is stored in muscles and liver and it is a branched polysaccaride.

Cellulose is the storage form of glucose in plants and leaves.
