I believe that the contraction of skeletal muscles is based on myosin cross bridges binding to actin the n flexing. Skeletal muscles consists of a repeating structure of myosin and actin fibers. Each myosin thick filament is surrounded by actin filaments, and each thin filament is surrounded by thick filaments. Several of these filaments bundles makes up the functional portion of a muscle cell.
Answer:
One similarity between the sunflower plant and paddy plant is that both of them have a non-woody stem. The three differences are; sunflower plant is a dicot, and has branching veins and taproots while paddy plant is a monocot, and has parallel veins and fibrous roots.
Explanation:
The paddy plant is a monocot (monocotyledon), where only one embryonic leaf (cotyledon) is present inside the seed coat. The monocots have a fibrous root system and their leaf veins are parallel. The sunflower plant is a dicot or dicotyledon, which contains two embryonic leaves inside the seed coat. The leaf veins of dicots are branched. They have taproots. Both the sunflower plant and paddy plant can be used as food. Both have a non-woody stem.
Answer:
ATP provides the cell with a way to handle energy in an efficient manner. The molecule can be charged, stored, and used as needed. Moreover, the energy from hydrolyzing ATP is delivered as a consistent amount.
The correct answer is this: IT DOES NOT DEPEND ON INSECT POLLINATION.
In gymnosperms, pollination involves the transfer of pollen from the male cones to the female cones. Gymnosperms mainly depend on non insect method of pollination. Pollination in gymnosperms is often carried out by wind, birds, bats, etc.<span />
<span>This is most likely caused by horizontal gene transfer, which is the process of transmission of genetic material between organisms caused by any process different than parent to offspring transmission (which would be vertical transmission). This has heavily influenced evolution</span>
