Answer:
C. Sprout every year, year after year
Explanation:
The perennial plants are the plants that live for more then two years, thous some may argue that they are plants that live more then three years. Whichever the case, they are not short-lived plants, but are capable of surviving for numerous years, unlike the annuals and biennials. Theoretically, the shrubs and trees would fall into this category, but they are classified separately, and this term is not used for them, but for smaller plants that do not have or have very little woody parts. These plants tend to sprout every year, and even though they seemingly die in the autumn, their roots are alive, and they emerge and grow again in the spring, sprouting again. That process repeats itself for numerous years.
Interspecific competition can occur between two different species competing for the same resource in an ecosystem. So for this particular bug population, there may be another insect species that competes for the same food source or another resource, such as material or space for breeding habitat. This can lead to selective pressure, and may result in the different species evolving a more specific diet or inhabiting a niche environment.
The answer is A. You are welcome have a nice day
Answer:
There are more thick filaments than thin filaments. (Ans. D)
Explanation:
Smooth muscle doesn't contain the calcium binding protein troponin. In smooth muscle, contraction is initiated by a calcium regulated phosphorylation of myosin, rather than a calcium activated troponin system.
The intermediate filaments are connected to each other with the help of dense bodies, which are attached to adherens junction in the cell membrane of the smooth muscle cells which are known as sarcolemma.
Smooth muscle cell lack sarcomeres because their filaments occur as a spiral and actin, myosin filaments are not regularly arrayed along the length of the cell.
In smooth muscle thin filaments occurs more than thick filaments.
So, the answer is D.
