Answer: The basic theme of whale evolution is the development of large animals from much smaller ancestors, and nowhere is this more evident than in the case of multi-ton sperm and gray whales, whose ultimate forebears were small, dog-sized prehistoric mammals that prowled the riverbeds of central Asia 50 million years ago. Perhaps more intriguingly, whales are also a case study in the gradual evolution of mammals from fully terrestrial to fully marine lifestyles, with corresponding adaptations (elongated bodies, webbed feet, blowholes, etc.) at various key intervals along the way.

xxMikexx [17]
The correct answer is letter C.
Bryophytes have biflagellate gametes and cuticle. The cuticle serves as the covering of the soft tissue of the plant which provides protection and prevents damages on the walls of the plants. The biflagellate gametes develop also as a form of protection as well. These plants have an aquatic ancestry because of their dependence on water for reproduction and survival.

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.

In an examination of a sample of muscle tissue, you might notice that the sample consists of striated cells with multiple nuclei
Elis [28]

Answer: SKELETAL MUSCLE

Explanation:

Skeletal muscles is a type of muscle tissue that forms those muscles that move the bones of the skeleton,straited because straitations (strips) can be seen on microscopic examination and involuntary as it is under conscious control.

Although most skeletal muscles move bones,they also accomodate a degree of voluntary control in breathing.

A lot of movements can be finely coordinated.example; writing but may also be controlled subconsciously, maintaining an upright position does not normally require thoughts unless a new locomotor skill is being learned example skating or cycling and the diaphram maintains breathing while asleep.

The fibre (cells) of the skeletal muscle are cylindrical,contain several nuclei and can be up to 35cm long.

Skeletal muscle contraction is stimulated by motor nerve impulses originating in the brain or spinal cord and ending in the neuromuscular junction.

The contraction of a whole skeletal muscle occurs because of coordinated contraction of it's individual fibres.
