The Cycle May Convert Into Lytic Type Resulting From Environmental Exposure

Phage When Gets Incorporated With The Bacterial Chromosome Is Called Prophage

Lysogenic Bacteria May Get Infected By The Related Phage

The Bacterium Continues To Live And Reproduce Normally

Mitochondria

Chromosomes

Ribosomes

Nucleus

Neurospora

Rhizopus

Penicillium

Pilobolus

A Cardiac Muscle Cell.

All Of These

A Smooth Muscle Cell.

A Skeletal Muscle Cell.

They Contain Ancestors For Fungi Plants & Animals

Their Members Have Characteristics Which Separate Them From Other Kingdoms

They Do Not Develop From Blastula Or Embryo

They Only Include Unicellular Aquatic Eukaryotic Organisms

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

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

All Are Correct

They Are Seedless And Their Leaves Are Called Fronds

They Belong To Sphenopsida

They Live In Shady And Moist Areas.

They Show Circinate Vernation.

Ionic Imbalance May Also Cause It.

All Of These

The Major Event In It Is Accumulation Of Lactic Acid.

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

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 Even Capable Of Sexual Reproduction.

They Are Both Herbaceous And Woody

Vascular Bundles Are Ring Shaped In Their Stems.

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

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 Provides Muscle Attachment

Like All The Other Types Of Exoskeleton, They Lack Sensation

It Permits Gaseous Exchange

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

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

Spore Formation Occurs Through Meiosis

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

It Involves Alternation Of Morphologically Different Generations

An Infected Mother Cannot Pass The Virus To Her Baby.

Results In Enlargement Of Lymph Nodes

Is A Host Specific Disease

Can Be Prevented.

Both ‘A & ‘B

Sensory Organs

Muscles

Glands

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.

None Of These

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