Phage When Gets Incorporated With The Bacterial Chromosome Is Called Prophage

The Bacterium Continues To Live And Reproduce Normally

Lysogenic Bacteria May Get Infected By The Related Phage

The Cycle May Convert Into Lytic Type Resulting From Environmental Exposure

Nucleus

Ribosomes

Mitochondria

Chromosomes

Pilobolus

Rhizopus

Penicillium

Neurospora

All Of These

A Cardiac Muscle Cell.

A Smooth Muscle Cell.

A Skeletal Muscle Cell.

They Contain Ancestors For Fungi Plants & Animals

They Only Include Unicellular Aquatic Eukaryotic Organisms

Their Members Have Characteristics Which Separate Them From Other Kingdoms

They Do Not Develop From Blastula Or Embryo

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

All Are Correct

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

There Is A Definite Control System That Regulates The Homeostatic Activities

They Show Circinate Vernation.

They Are Seedless And Their Leaves Are Called Fronds

They Live In Shady And Moist Areas.

They Belong To Sphenopsida

All Of These

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

Ionic Imbalance May Also Cause It.

The Major Event In It Is Accumulation Of Lactic Acid.

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.

Contain Mainly Unicellular Organisms.

Their Contractile Vacoule Is Respobsible For Water Regulation.

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

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

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.

Like All The Other Types Of Exoskeleton, They Lack Sensation

It Permits Gaseous Exchange

It Provides Muscle Attachment

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

It Involves Alternation Of Morphologically Different Generations

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

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

Can Be Prevented.

Results In Enlargement Of Lymph Nodes

An Infected Mother Cannot Pass The Virus To Her Baby.

Is A Host Specific Disease

Ganglia

None Of These

Muscles

Both ‘A & ‘B

None Of These

Increases Transpiration By Increasing The Surface Area Of The Leave.

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

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