When there is excessive loss of water from extracellular fluid then osmotic pressure in extracellular fluid rises. Extracellular fluid means fluid present outside the cells. Osmotic pressure is defined as the pressure applied to solution to stop movement of solvent molecules through semipermeable membrane. Osmosis is the movement of solvent (water) molecules from high solute […]
Insulin and Glucagon are the hormones that helps to maintain normal range of blood sugar level. The glucagon action is opposite to that of insulin. They both work in a balance to maintain blood sugar to normal. When blood sugar is high, then pancreas secretes insulin and when blood sugar levels is low, then pancreas […]
Photosynthesis process used by plants to convert light energy from sunlight into sugar plant energy. The two phases of photosynthesis are: 1) Light reactions also called as photochemical reactions is the first stage of photosynthesis that converts the light energy into sugar. 2) Calvin Cycle or light-independent reaction or dark reactions or carbon fixation reactions […]
In pea plants, flowers are either white or purple; the purple color is produced by pigments called anthocyanins. The production of anthocyanins is a two-step process: the first is controlled by the C gene and the second by the P gene. Both genes must produce functional proteins for anthocyanin to be expressed. For each gene, the dominant (C and P) alleles produce functional proteins. You cross two pea plants, each with the genotype CcPp. What proportion of their offspring will have white flowers?
Answer: The proportion of their offspring will have white flowers is 7/16 Explanation: The production of anthocyanins is controlled by dominant C and P gene. Thus, absence of one or both dominant C or P results in white flowers. According the cross that is shown in image, the answer is 7/16
Rhizopus, called as bread mould is a saprophytic and parasitic fungi that are found on substances such as fruits, vegetables and bread etc. and on moist or damp places. Rhizopus, a zygomycete is a genus under the phylum Zygomycota. Brief about life Cycle of Rhizopus: 1. Aerial hypha produces a sporangium. 2. Sporangium bursts and […]
Carbohydrates are one of the important food group for healthy diet. The two main forms of carbohydrates are sugars and starch. Sugars such as fructose, glucose, and lactose. Starches such as rice, breads, and cereals. The body breaks down carbohydrates into smallest units called as glucose. Glucose is the main source of energy for our […]
– Lemons contains carbohydrates and water. Carbohydrates composed of fibers and sugars ( glucose, fructose and sucrose). – Lemon contains 70% sugar and strawberry contain 40% sugar. – Lemon tastes sour even it contains more sugar because of the high amount of citric acid that do not dominates the sweet taste and thus lemon is […]
