Nictitating membrane

Mimicry

They belong to class Amphibia

Mast cells.

Stomach.

Six segments.

Proximal convoluted tubule.

Muscles of the ducts of glands.

Muscular tissue consists of muscle fibers, it is not a connective tissue. Bone and cartilage are specialized connective tissue and blood is fluid connective tissue.

Connective tissue.

Anal styles in male.

All of the above.

The exchange of respiratory gases.

Inelastic white fibrous tissue.

A complex network of nerve cells or neurons forms the nervous system.
This system is responsible for transmitting electrical impulses throughout the body.

Respiratory pigment.

Malpighian tubules.

Muscle cells aid in the movement of body parts in humans.
These cells have the ability to contract and relax, which causes the movement of body parts.
Nerve cells send and receive signals from the brain.
Glandular cells secrete sweat, saliva, breast milk, digestive enzymes and hormones, among other substances.
Skin cell functions in protection, secretion, sensation, etc.

Anal

Deposition of bony matter by osteoblasts only.

Hyaline cartilage.

Epithelial tissue.

Frogs have nictitating membrane which protect their eyes in water.

Lymphocyte.

Frogs have nictitating membrane which protect their eyes in water.

Group of variety of cells formed to carry out similar functional.

Synthesis of prothrombin.

Earthworm does not have a true heart as it is an invertebrate, but they have five pairs of aortic arches that are referred to as the heart.
These arches are present in the anterior region of the body and they connect ventral and dorsal vessels and pump blood throughout the body.

Ostia.

Bone to muscle.

Digestion begins first at the mouth where the parts like mandibles and maxillae help to chew the food.
The mandibles cut off pieces of food and crush them before they are swallowed.
The other mouthparts help select the food and manipulate it between the jaws.

Squamous epithelium.

Iron.

Aves.

No cell at all, but is a product of epithelial cells.

Sarcomere.

Neutrophils.

All of the above

On cell surface.

Anal styles are absent in females.

Heart.

Areolar connective tissue.

Columnar.

Chondrin.

Cemented directly to one another to form a single layer.

Connective tissues are the tissues that connect the different parts of the body.
Bone and cartilage are the specialized supporting connective tissues.
They give shape and size to the external and internal structure of the body.
Muscles, nerves and epithelium are separate types of tissues with distinct functions.

Metamorphosis.

Trehalose is the sugar circulating in the blood or haemolymph of most insects.
It is the major blood sugar in insects playing a crucial role as an instant source of energy and in dealing with abiotic stresses.

Humerus.

Hyaline cartilage.

Myelin sheath is discontinuous.

Excretion is performed by Malpighian tubules.
Each tubule is lined by glandular and ciliated cells.
They absorb nitrogenous waste products and convert them into uric acid which is excreted out through the hindgut.
Therefore, this insect is called uricotelic.
The fat body nephrocytes and urecose glands also help in excretion.

Actin

The earthworm has no skeleton but during burrowing, the anterior end becomes turgid and acts as a hydraulic skeleton.
It is due to coelomic fluid.
The coelom is filled with alkaline, milky coelomic fluid.

The blood in cockroaches is called hemolymph.
Hemolymph is colourless because there is no respiratory pigment.
The cockroaches lack respiratory pigment.

Dense regular connective tissue.

Nerve cells.

Adipose tissue is of mesodermal origin and hence is an example of connective tissue.

The integumentary nephridia open directly to the exterior and so they are called as the exonephric nephridia.
As the septal and pharyngeal nephridia discharge their waste products into the alimentary canal, they are called as the enteronephric nephridia.

Lymphocytes.

Chondroitin.

Simple squamous epithelium lines the inner walls of blood vessels. It is composed of largeflat cells which rest on a thin basement membrane.

Red bone marrow

The cockroach has an open vascular system consisting of sinuses filled with blood.
The blood of cockroach is without haemoglobin or any other respiratory pigment.
This type of blood devoid of any respiratory pigment is called haemolymph.

Areolar connective tissue.

One pair of wings.

Epithelial tissue.

Lymphocyte.

Collecting ducts.

Involuntary and striated.

Beneath the skin Set.

Ureotelic.

Respiratory tract.

Calcium phosphate.

Trachea

Prevent clotting.

Myelin sheath.

Turn flexible.

Ciliated epithelium.

Both white and red muscle fibres.

Bone

Chitin.

Mast cells.

Bile duct.

Connective tissue.

Nephridia in Pheretima are of the micronephridic type.
Micronephridia is smaller in size, sometimes microscopic and are numerous in each segment.
They are networks of fine tubes lying on the body wall and septa in each segment.

Three and six.

They are single – layered in thickness.

Cutaneous respiration.

Earthworms eat decaying plant and animal matter in the soil.
They are classic examples of detritivores because they consume organic material from the soil.
Leech feeds on blood. Fowls feed on seeds and insects and caterpillar larva on leaves.
As earthworm is detritivorous, it is used in the preparation of compost.

Ciliated epithelium is present in inner surface of hollow organs like bronchioles ando fallopian tubes.

More sodium ions enter the axon as compared to potassium ions leaving it.

Haversian canals are a series of microscopic tubes in the outermost region of bone called cortical bone that allows blood vessels and nerves to travel through them.
They are absent in muscles,nerves and cartilage.

Fibrous protein.

Ribosomes.

Phallic gland

Heparin and histamine.

Myofibril.

The earthworm is an invertebrate animal which belongs to the phylum Annelida.
They are made up of many segments.
Each segment of earthworm contains two nephridia.
Each nephridia open into the body cavity of an earthworm.
The nephridia is composed of two parts, namely, nephridiostome and nephridiopore.
In earthworm, the urea, salts and water are excreted out through the nephridiopore of nephridia.

No antibody.

Ribosomes.

Cardiac muscles.

Sodium.

"Myo" refers to "Muscles".
Myology is the study of the muscular system, including the study of the structure, function, and diseases of muscle.

Ciliated epithelial cells.

Inner lining of cheek.

Ommatidium.

Modified white fibrous tissue.

Cockroach.

Setae helps in locomotion of earthworms.

Sublingual

Lining of blood vessels.

Copulatory pads are absent in female frog. These are present on the first digit of the fore limbs.

Brain and spinal cord.

Frogs are beneficial to man because they protect crops and eat insects. They maintain ecological balance. They link food chain and food web. Muscular leg of frog is used as food by man.

Areolar tissue.

Development through nymph stage.

Nymph.

Increase in number.

Adipose tissue.

In Cockroach, The claws and the arolium help in locomotion on rough surfaces whereas planulae are useful on smooth surfaces.

When both the sexes are present on the same individual, it is called hermaphrodite. When young ones resemble adult, the development is called direct development. Chemoreceptor is composed of two terms, viz. chemical and receptor. Blood gland in earthworm produce blood cells and haemoglobin.
