Write a note on blood plasma.

1.Plasma, constituting the straw-colored, slightly alkaline, and viscous component of blood, comprises 90-92% water and 8-10% soluble proteins. Among these proteins, such as serum albumin, serum globulin, heparin, fibrinogen, and prothrombin, collectively make up 7% of the plasma, contributing to its crucial physiological functions. 2.Furthermore, plasma serves as a carrier for essential nutrients like glucose, … Read more

Given below are the characteristics of some modified respiratory movement. Identify them. a. Spasmodic contraction of muscles of expiration and forceful expulsion of air through nose and mouth. b. An inspiration followed by many short convulsive expiration accompanied by facial expression.

Sneezing involves the involuntary contraction of expiratory muscles, leading to a forceful release of air through the nose and mouth.

Identify the incorrect statement and correct it, a. A respiratory surface area should have a large surface area. b. A respiratory surface area should be kept dry. c. A respiratory surface area should be thin, may be 1mm or less.

B. A respiratory surface area should be kept dry Correct statement: It is essential to maintain moisture on a respiratory surface.

What is vernalization? Give its significance.

1. Vernalization is the artificial exposure of plants to low temperatures to boost seed production or induce flowering. 2. This process involves subjecting a fully hydrated seed to a cold treatment, curtailing the plant’s vegetative phase and promoting early flowering. 3. The vernalization sites vary among plants and can include the germinating seed, apical meristem … Read more

What is short day plant? Give any teo example.

1. Short day plants bloom with a prolonged period of darkness and a brief period of light, typically flowering in spring. 2. Long day plants, on the other hand, flower in response to a short period of darkness and an extended period of light, usually during summer. 3. Day-neutral plants flower independently of the duration … Read more

Enlist the role and deficiency symptoms of potassium.

Function: Regulating anion-cation balance within cells, essential for protein synthesis, contributing to cell membrane formation, modulating stomatal activity, activating enzymes, and sustaining cellular turgidity. Deficiency Indicators: Manifested as yellowing leaf edges and premature cell death.

Difference between Arithmetic and Geometric growth.

Arithmetic Growth: 1. Only one daughter cell continues division, while the other undergoes differentiation and maturation. 2. Rate of growth is constant, resulting in a linear curve described by Lt = Lo + rt. Geometric Growth: 1. Both daughter cells continue to divide and redivide. 2. Rate of growth is initially slow but becomes rapid, … Read more
