1.It is a diluting fluid used for WBC count. Turk's solution contains glacial acetic acid and Gentian violet.
2. The glacial acetic acid lyses the red blood cells and the Gentian violet stains the nuclei of the leucocytes.

1. Myoglobin is a red- coloured respiratory pigment of the muscle fibre.
2. It is similar to haemoglobin and contains iron group that has affinity towards oxygen and serves as the reservoir of oxygen.

1. While fasting, these cells maintain our life by producing and supplying energy as fuel.
2. Adipose tissues are also found in subcutaneous tissue, surrounding the kidneys, eyeball, heart, et., Adipose tissue is called white fat or white adipose tissue

Species is the basic unit of classification III the taxonomic hierarchial system. It is a group of animals having similar morphological features (traits) and is reproductively isolated to produce fertile offspring.

Calcium and sulphur.

The Amount of energy got from Anaerobic respiration is very less. One glucose molecule yields only 2 ATP I molecules. But this energy is sufficient for microbes since they are unicellular.

The photoperiod required to induce flowering is called critical day length

Significance of imbibition:
1. During germination of seeds, imbibition increases the volume of seed enormously and leads to bursting of the seed coat.
2. It helps in the absorption of water by roots at the initial level.

Fusiform initials and ray initials.

Starch is a storage polysaccharide made up of repeated units of amylose and amylopectin.

Chloroplast, Mitochondrion

The composition of plasma is not always constant. Immediately after a meal, the blood in the hepatic portal vein has a very high concentration of glucose as it is transporting glucose from the intestine to the liver where it is stored. The concentration of the glucose in the blood gradually falls after sometime as most of the glucose is absorbed.

Aubiquitine ligase is activated called as the anaphase-promoting complex cyclosome (APC/C) leads to degradation of the key regulatory proteins at the transition of metaphase to anaphase. APC is a cluster of proteins that induces the breaking down of cohesion proteins which leads to the separation of chromatids during mitosis.

Rotational movement of the head - Ampulla of the semicircular canal in the inner ear.

Drilosphere is the part of the soil influenced by earthworm secretions, burrowing and castings.

(i) Some of the inhaled air never reaches the areas of gaseous exchange but respiratory passages are filled by it.
(ii) Such lodged sites of respiratory tract do not undergo gaseous exchange such sites constitute a dead space.
(iii) It amounts to approximately 150 mL.

Earthworms are ureoteles in the soil and when in water they are ammonoteles

Development is said to be direct if no larva is formed in the life cycle of an organism. Eg: Earthworm.

Major functions of connective tissues are binding and support, protection, insulation and transportation of substances.

(i) In the gastrula stage of embryo on the root of gastrocoel an archenteron is formed.
(ii) Archenteron develops chordodorsatis or notochord dorsally.
(iii) Its anterior end forms brain and posterior axis form spinal cord.
Eg: Hemichordates and chordates.

(i) Root climbers: Plants climbing with the help of adventitious roots (arising from node). Eg: Piper betel,Piper nigrum, Pothos.
(ii) Stem climbers: These climbers lack specialised structure for climbing and the stem itself coils around the Support. Eg: Ipomoea, Clitoria, Quisqualis.

(i) A beam of electron passes through the specimen to form an image. It provides two dimensional image.
(ii) The magnification is 1-3 lakhs times and resolving power is 2 - 10 Å.

(i) Presence of well organised plant body which is differentiated into roots, stem and leaves.
(ii) Presence of eustele.
