The question is incomplete as it does not have the options which are:

A) chordate.

B) echinoderm.

C) nematode.

D) mollusc.

Answer:

A) chordate.

Explanation:

The animals can be distinguished based on embryonic development and are categorized into two types: Deutrostomes and the protostomes.

The deuterostomes are the organism in which the small opening in the embryo called the blastopore develops into the anus. The deuterostomes organism belongs to two groups of the animal: the echinoderms and the chordates.

The chordates are the animals which possess the bilateral symmetry that is can be divided into left and right sides and posses true cavity or coelom.

Thus, Option-A is correct.

4. Cornea.

5. Iris.

6. Optic nerve.

7. Photoreceptor.

8. Retina.

9. Rod.

Explanation:

A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.

Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes.

An eye can be defined as a specialized organ of sight with the capability to receive visual images that are subsequently transduced into neural signals and relayed to the brain for processing and interpretation. Some of the components of the human eye matched with their description are;

1. Aqueous humor: a transparent liquid which is located between the cornea and iris.

2. Ciliary muscles: muscles attached to the lens to change its shape.

3. Cone: a photoreceptor cell which functions best in bright light. It detects color.

4. Cornea: the transparent portion of the sclera at the front of the eye.

5. Iris: a special part of the choroid layer composed of colorful tissue.

6. Optic nerve: the nerve connecting the eye to the brain.

7. Photoreceptor: specialized cells located in the retina that receive light images.

8. Retina: a delicate light-sensitive membrane covering the inside of the eyeball.

9. Rod: a photoreceptor cell which is sensitive to dim light, but detects no color.

10. Sclera: a fibrous material surrounding the eye to give it shape.

11. Vitreous humor: a transparent jellylike substance filling the eyeball.

  • Insulin enters the rough endoplasmic reticulumn in its inactive form (proinsulin).
  • The rough endoplasmic reticulumn converts it to active form (insulin).
  • The rough endoplasmic reticulumn transfer the insulin to glogi comlpex
