Answer:

Glucose

Explanation:

Every cell of the body needs glucose for carrying out the metabolic processes taking place inside it. As the cell is inside blood collection tube,there will be no synthesis of erythrocytes in the tube.

The components like iron, calcium and vitamin B 12 is required for the synthesis of erythrocytes so there is no need of such components.

The cell will only require glucose to stay alive in the blood collection tube.

2. Ciliary muscles.

3. Cone.

4. Cornea.

5. Iris.

6. Optic nerve.

7. Photoreceptor.

8. Retina.

9. Rod.

10. Sclera.

11. Vitreous humor.

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.

Which of the following best describes the mechanism by which steroid hormones control gene expression? View Available Hint(s) Wh
Veseljchak [2.6K]

Answer:

Steroid hormones that enter the cell activate receptors. These hormone-receptor complexes then bind HREs and influence gene expression.

Explanation:

Mechanism of action of steroid hormones is as follows:

  • Steroid hormone enters cell and bind to the receptor.
  • Translocation of activated receptor- ligand complex into nucleus.
  • This complex then bind to another receptor on the chromatin.
  • Steroid receptors form dimers.
  • Act on DNA
  • These hormone-receptor complexes then bind HREs and influence gene expression.
  • Augmentation or Suppression of transcription.

Tom [10]

Answer:

  • There is a diversity among beings some are very large, while others are microscopic in nature. However, we are always very curious about the classification of the insecticides in the ecological pyramid because there are termed to be the invertebrates having a proper body with all the segments i.e head, thorax, and abdomen well placed to form the structure of the living being.
  • As they are mostly characterized for there small size and very complicated form of morphology, while the insects are found to be living inside the soil and on the plant structures.

Explanation:

  • Insects are the one who plays the pivotal role in the decomposition of the living beings i.e both plants and animals inside a specific region. While, the insects have the basic feature to cover them selves with a protective layer of proteins,so, they can shield themselves from any degree of harm while living inside the environment.
