The correct answer is the first statement.
In intraspecies competition, there is a competition for recourses among the individuals from the same species. This is due to the limited availability of the recourses in the habitat. Only the fittest individuals will be able to gather enough recourses and survive.

The major difference between starch, glycogen, and cellulose and their adjacent glucose subunits is the ________.
sveta [45]

Answer:

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

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

<u>Glycogen</u> 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.

Stells [14]

Answer:

A. The number of cells that are dying is balanced by the number of new cells that are being formed.

C. Harmful waste products may be accumulating.

D. The cells are likely running out of nutrients.

Explanation:

During the stationary phase, the number of viable cells remains constant. This may be due to a balance between cell division and cell death wherein the total number of newly formed cells and the cells undergoing death are equal.

Nutrient limitation is one of the several factors that make the microbial cells to enter the stationary phase. Depletion of nutrients slows down the population growth.

Accumulation of toxic waste products as it occurs during the growth of anaerobic bacteria also adversely affects the population growth.

For example, the accumulation of lactic acid and other organic acids (by-products of anaerobic respiration) inhibits the growth of the population by making the medium acidic.
