Question : The given graph shows length-tension curve for a typical vertebrate sarcomere. By analysing the graph, what can you deduce regarding the muscle contraction? (i) Neither the myosin filaments nor the actin thin filaments change in length when a sarcomere shortens or is stretched. Instead, it is the extent of ocerlap between actin and myosin filaments that changes. (ii) The total tension produced by a sarcomere is proportional to the total number of cross-bridges that can interact with actin filaments, and this number in turn is proportional to the amount of of overlap between thick and thin filaments. (iii) The tension produced by the muscle is maximal when the overlap between thick and thin filamentss allows the largest number of myosin cross-bridges to bind to actin. (iv) Tension dropsoff with increased lenght, because the thick and thin filaments overlap less and fewer cross-bridges can bind. Tension drops off with decreased length, because thin filaments at the two ends of the secromere begin to collide with each other, preventing further shortening.

Question : The given figure shows growth of two leaves over the period of one day. If AG = absolute growth and RGR= relative growth rate, then select the correct option.

Answer»

`{:(AG "for leaf" A,RGR "for leaf" A,AG "for leaf" B, RGr "for leaf" B ),(1%, 1, 2%, 2):}`
`{:(AG "for leaf" A,RGR "for leaf" A,AG "for leaf" B, RGr "for leaf" B ),(100%, 5, 10%, 5):}`
`{:(AG "for leaf" A,RGR "for leaf" A,AG "for leaf" B, RGr "for leaf" B ),(5, 100%, 5, 10%):}`
`{:(AG "for leaf" A,RGR "for leaf" A,AG "for leaf" B, RGr "for leaf" B ),(5, 100%, 5, 100%):}`

Solution :Absolu7te growth rate `(AGR)`: increase in total growth of two organs or organisms is measured and comparison of total growth per unit time is called absolute growth. Absolute growth rate is the total growth per unti time.
Relative growth rate `(RGR)`: It is growth per unit time per unit INITIAL growth.
`RGR =("Growth in given time period")/("Measurement at start of time period")`
AG ofleat `A = 10 cm^(2) - 5 cm^(2) = 5 cm^(2)`
RGR for leaf `A = (5)/(5) xx 100 = 100%`
AG for leaf `B = 55 cm^(2) - 50 cm^(2) = 5 cm^(2)`
RGR for leaf `B = (5)/(50) xx 100 = 10%`
Though the absolute growth is same for both the leaves (A and B), relative rate of growth is more in leaf A because of its initial SMALL size.

Answer»

the major target sites and the metabolic actions of the anabolic homone secreted by the beta cells of heterocrine gland
the major target sites and the metabolic action of the hormone secreted by alpha cells of pancreas
the major target sites and the functions of the hormone secreted by the anterior pituitary gland.
the major target sites and the metabolic actions of the hormone secreted by the parafollicular C cells

Solution :Beta cells of pancreas produce INSULIN. It promotes PROTEIN synthesis in tissue from amino acids and reduces catabolism of PROTEINS. It increases the synthesis of fat in the adipose tissue from fatty acids and reduces the BREAKDOWN and oxidation of fat.
Insulin decreases the lvel of glucose in the blood it acts by increasing the rate at whichglucose is transported out of the blood and into cells and by stimulating muscle cells to take up sugar from the blood and convert it to GLYCOGEN.

Question : the given diagram illustrates stomata closing the major mistake in the diagram is that

Answer»

the concentration of the `K_(+)` should be more outside the guard CELLS
the concentration of the `K_(+)` should be equal on both INSIDE and outside
the peripheral walls of the guard cells should be thicker
the water should move inside the guard cells.

Solution :During stomatal CLOSURE, the `H^(+)` ions diffuse out of the guard cell chloroplat. Any malate presents in the cytoplasm combines with `H^(+)` to form malic acid. Undissociated malic acid promotes leakage of ions. As a result `K^(+)` ions dissociate from malate and pass out of the guard cells. LOSS of `K^(+)` ions decreases osmotic concentration fo guard cells as compared to adjacent epidermal cell. this CAUSES exomosis andhence turgidity of the guard cells decreases.

There are plants having DESERT adaptations in this tree. They help them to sustain in unfavourble conditions as well.
Other examples are incorrect because PTERIDOPHYTES are a primary group. There is no tree in it. Nephrolapis is included in pteridophytes. Sperms are different in seed form and adaptation than gymnopems.
