Explain the bone structure​

Biology

Answer:

Bones are organs composed of hard living tissue providing structural support to the body – it's scaffolding. It is a hard matrix of calcium salts deposited around protein fibers. Minerals make bone rigid and proteins (collagen) provide strength and elasticity. ... The outer layer of bone is called Cortical bone.

<u>The adult human skeleton is made up of 206 bones. These include the bones of the skull, spine (vertebrae), ribs, arms and legs. Bones are made of connective tissue reinforced with calcium and specialised bone cells. Most bones also contain bone marrow, where blood cells are made.</u>

While studying the function of a G protein-coupled receptor you develop a modified GTP molecule that has the same binding capabi
laila [671]

<u>Answer:</u>

Effects Include:

Activates secondary messengers such as cAMP which further activates number of hormones like

  • ADH: production of this hormone causes kidneys to retain more water inside body.
  • GHRH: release growth factors and stimulates growth of organism.
  • ACTH: produces fight or flight responses i.e rise in heart beat, rise in Blood pressure etc
  • TSH: Stimulate the synthesis of Thyroid hormone and enhances the metabolism of body. In rare cases causes Goiter without the deficiency of Iodine.
  • LH: Stimulate follicle maturation and formation of ovules in women.
  • Calcitonin: Decreases blood calcium level by deposition calcium in bones. This effect weakens the muscles.
  • Glucagon: Stimulates glycogen breakdown from liver and muscles and many more effects.

<u>Explanation:</u>

Background Knowledge:

GPCR (G Protien coupled receptors) are present inside plasma membrane in huge amount. As name suggest that these receptors are coupled with G proteins during their inactive state present inside of the cell. During their Inactive state these G proteins are bounded with GDP molecule.

Upon receiving signal molecules from outside of cell alters the shape of GPCR. These receptors also triggers change in G Protein, as a result of this GTP get attached with them. This protein further activates reaction cascades inside of the cell.

What happen if GTP cannot be hydrolyzed to GDP + Pi?

If GTP cannot hydrolyzed in to GDP + Pi than, it cannot be able to dissociate from G proteins. Cascade system doesn't stop and produces many effects on body.

Effects Include:

Activates secondary messengers such as cAMP which further activates number of hormones like

  • ADH: production of this hormone causes kidneys to retain more water inside body.
  • GHRH: release growth factors and stimulates growth of organism.
  • ACTH: produces fight or flight responses i.e rise in heart beat, rise in Blood pressure etc
  • TSH: Stimulate the synthesis of Thyroid hormone and enhances the metabolism of body. In rare cases causes Goiter without the deficiency of Iodine.
  • LH: Stimulate follicle maturation and formation of ovules in women.

  • Glucagon: Stimulates glycogen breakdown from liver and muscles and many more effects.

Goryan [66]

Answer:

All animals share a common ancestor.

Explanation:

All living organisms including animals have evolved from common ancestral organism. It is evident from various researches in relation evolutionary diversification of species.  The process by which numerous variety of species are formed from a common ancestor is known as speciation. The attached diagram showing the phylogeny tree of life is a solid evidence of common ancestral origin of life.
