Answer:
True
Explanation:
Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
25% chance because when you do a Punnett square for your genes you find that only 1 of 4 are tt and 2 are TT and one is Tt so the percentage for the plant to be short would be 25%
what are you asking just to be clear
Although earthquakes often occur before a volcanic eruption, they are not the cause. The earthquakes are the result of magma (molten rock) moving underground leading up to an eruption. A few volcanic eruptions are thought to have been triggered or initiated by earthquakes, but this is not the typical case.
Answer: calcium is released from the sarcoplasmic reticulum
Explanation:
Muscle contraction is the stimulation of sites that produce stress within muscle fibres.
Calcium ions bind to tropomyosin in inducing muscle fibre contraction, exposing active site for Crossbridge formation on actin. Then ATP binds to myosin, transferring the myosin to its high-energy state, freeing the myosin head from the active actin site. Triggering tension-generating sites within muscle fibres.
Hence, the contraction process is initiated with teh relaease of calcium from sarcoplasmic reticulum.
