Binding Sites Of Actin Get Attached To The Myosin Head.

Troponin Uncovers The Actin Binding Sites.

Tropomyosin Gets Removed From The Binding Sites Of Actin Filaments.

Ca2+ Goes Back Inside Sarcoplasmic Reticulum.

They Are Multinucleated.

They Are 10 – 100 ?M In Diameter & Surrounded By Sarcolemma

They Contain O2 Storing Molecules Called Hemoglobin.

Their Cytoplasm Contains High Concentration Of Carbohydrates

Occur As A Result Of Bone Being Thin And Weak.

Due To Good Blood Supply It Results In Quick Healing.

They Are More Common Than In Adult Age.

It Involves Osteoblasts And Osteocytes.

Move With The Help Of Flagellum, Attached To The Anterior Pole Of The Body.

None Of These

Flagellum Whipping Backwards Moving The Organism Forward, And When Moves Forward The Organism Moves Backward.

Myonemes Can Change The Direction Of The Body By Making It To Shorten From Anterior To The Posterior Pole.

A Specific Organism Can Always Be Found In Association With A Given Disease

The Pure Culture Cannot Produce The Disease When Inoculated Into Susceptible Animal However The Causative Organism Isolated From Pure Culture Can Do So.

The Organism Can Be Isolated And Grown In Pure Culture In The Laboratories

It Is Possible To Recover The Organism In Pure Culture From The Experimentally Infected Animals

It Contains Adenine Guanine Thymine And Cytosine

The Pentose Sugar In It Is Ribose.

It Is Present In The Nucleoli

It May Be Folded Back On Itself To Give Double Helical Characteristics.

They Have Hydrostatic Skeleton.

They Move By Tube Feet

Their Shell Grows As The Animal Grows.

They Are Surrounded By Single Or Double Pieces Of Hard Skeleton.

They Are Present Through Out Life Of A Plant And Provide Them Whth Energy Through Glyoxylate Cycle.

They Are Signle Membranous Organelles

They Contain Enzymes Which Help In Conversion Of Fatty Acids Into Carbohydrate

They Are Abundant In Soyabeans But Absent In Pea.

Most Of Them Have Different Morphological Forms In-Different Stages Of Their Life Cycle

Their Classification Is Based On Pigment Composition

Almost All Of Them Are Aquatic

Their Zygote Unlike Plants Is Protected By Parental Tissue

They Are Lighter Than Water

They Contain Double Bond

They Are Usually Solid At Room Temperature

Their Specific Gravity Is Less Than 1

It Is Hydrophobic

It Is Flat, Square And Light Absorbing

It Is A Porphyrin Ring Or Tetrapyrrole Ring Structure

Composed Of Carbon And Nitrogen Atoms With Magnesium As Central Metal Ion, Which Is Coordinated With Nitrogen.

All Are Eukaryotes

They Are Multicellular.

They Are Heterotrophes

Non-Motile Organisms

It Results From Estrogen Deficiency.

There Is Reduction Of Bone Mass And Change In Chemical Composition Of The Matrix

Bone Eating Process Takes Over Bone Formation Process.

It Is Common In Old Age.

They May Show Limited Regenerative Capabilities

They Not Only Conduct Impulses But Also Generate Them

Like All The Living Cell, When They Mature And Divide To Form Similar Cells

They Are Not The Only Cellular Component Of Nervous System
