How can an injury to a peripheral nerve cause loss of both sensory and motor functions?

Answers

Answer 1

Answer: The reason is that peripheral nerves have both sensory and motor fibers.

Through these sensory fibers, peripheral nerves receive signal and send them to the brain. Also, through motor fibers, peripheral nerves send information to the muscles. When a peripheral nerve is damaged, the both functions will be lost.

An eye contains receptors called photoreceptors viz rod and cone cells. Cones are cone-shaped structures and are necessary for daylight vision. Unlike cones, rods are rod-like structures and are necessary for dim-light vision. Rods are far more numerous than cone cells.

In monocots the endosperm is a large portion of the seed, while in dicots this structure is virtually absent. Explain the absence of the endosperm in dicots

Answers

function of endosperm include in dicots like peas and beans food is stored in cotyledons not in endosperm that is why it is absent in dicots

What is endosperm ?

Endosperm developed from the triploid cell (3n) in the embryo sac where the second male gamete fuses with the diploid secondary nucleus to form primary endosperm nucleus (PEN) and a triploid cell which is called as triple fusion

Endospermic cells are mostly triploid but in some plants, they may be diploid (water lily) or polyploid (up to 15n)

In some of the dicots, mature seeds contain food stored in the endosperm, they are called endospermic or albuminous seeds, e.g. castor

In beans, peas, gram seeds, the endosperm is completely absorbed during development and food is stored in two cotyledons. They are called exalbuminous seeds

Endosperm mostly contains starch as a food reserve, but it may contain fats, e.g. castor, Endosperm provide nutrients to seeds during dormancy

Endosperm also contains certain hormones like cytokinins and helps in cell differentiation

What geological theory explains how llamas and camels, close relatives, might be found on different sides of the world?

Answers

The answer is continental drift.
Continental drift is the geological theory that explains how continents move through Earth's surface. All continents were once connected as one supercontinent Pangea. On that supercontinent, many related species, such as llamas and camels, lived together on one location. But after continents spread apart, related species were separated on different continents and adapted to different conditions
