Phage When Gets Incorporated With The Bacterial Chromosome Is Called Prophage

Lysogenic Bacteria May Get Infected By The Related Phage

The Cycle May Convert Into Lytic Type Resulting From Environmental Exposure

The Bacterium Continues To Live And Reproduce Normally

Chromosomes

Nucleus

Ribosomes

Mitochondria

Rhizopus

Neurospora

Penicillium

Pilobolus

All Of These

A Skeletal Muscle Cell.

A Cardiac Muscle Cell.

A Smooth Muscle Cell.

Their Members Have Characteristics Which Separate Them From Other Kingdoms

They Contain Ancestors For Fungi Plants & Animals

They Only Include Unicellular Aquatic Eukaryotic Organisms

They Do Not Develop From Blastula Or Embryo

Because Of This The Fluctuations Of Internal Environment Are Of Extremely Narrow Range As Compared To That Of External Environment

Homeostatic Mechanisms Keep The Internal Environment Fixed Despite Of Wide Changes In External Environment

There Is A Definite Control System That Regulates The Homeostatic Activities

All Are Correct

They Belong To Sphenopsida

They Live In Shady And Moist Areas.

They Show Circinate Vernation.

They Are Seedless And Their Leaves Are Called Fronds

Ionic Imbalance May Also Cause It.

The Major Event In It Is Accumulation Of Lactic Acid.

Lactic Acid Accumulation Turns Ph In Acidic Range Leading To Muscle Ache.

All Of These

Contain Mainly Unicellular Organisms.

Their Contractile Vacoule Is Respobsible For Water Regulation.

They Are Even Capable Of Sexual Reproduction.

Diploid Nucleus Being Smaller Is Responsible For Cells Metabolism And Growth While Polyploidy Nucleus Functions In Sexual Process.

They Are Both Herbaceous And Woody

They Have 4 Or 5 Sepals And Petals Or Their Multiple.

Vascular Bundles Are Ring Shaped In Their Stems.

They Have Parallel Vein Pattern On Their Leaves

Accumulate Waste In Leaves, Which Fall In Autumn.

Stored Excretory Products In Vacuoles, At A Concentration That Leads To Crystal Formation.

Production Of Black Wood In The Center.

Excrete Some Of The Waste Materials Directly Into Soil, Occasionally Using Them As A Chemical Weapon Against Other Competing Plants.

It Permits Gaseous Exchange

It Provides Muscle Attachment

It Contains Joints, For The Same Purpose As Present In Human Skeletal System

Like All The Other Types Of Exoskeleton, They Lack Sensation

Both The Gametophyte And Sporophytes Are Haploid Generations Thus Can Produce Haploids Gametes To Continue The Diploid Number On Fertilization

Spore Formation Occurs Through Meiosis

It Involves Alternation Of Morphologically Different Generations

Their Gametophyte Is Independent While Sporophyte Depends Upon Gametophyte For Nutrition.

An Infected Mother Cannot Pass The Virus To Her Baby.

Is A Host Specific Disease

Can Be Prevented.

Both ‘A & ‘B

Stomata Closing In Sufficient Supply, And Opening In Restricted Supply Of Water.

Small And Thick Leaves To Decrease The Surface Area Proportional To The Volume Of The Leave.

None Of These

Increases Transpiration By Increasing The Surface Area Of The Leave.
