<h2>Tropomyosin</h2>
Explanation:
This protein is most likely: Tropomyosin.
Sacromere is the structural unit of myofibrils i.e. the fibres of the muscles.
Tropomyosin is the muscle protein that function in contraction of muscle filaments.They are arranged laterally along the myofilament. When the researcher is observing the sacromere, she is observing the muscle fibre. So, the protein that lines the periphery along the thin filament is more likely to be tropomysin.
The immigration of extra rabbits into a forest ecosystem can affect the population of herbivores living in the forest.
<h3>What is immigration?</h3>
Immigration is the movement of people or animals from external locations into a population.
With new individuals moving into a population, the population size increases with other factors being constant.
With the increase in the population size, competition for resources increases accordingly.
Thus if extra rabbits move into a forest ecosystem, the population of herbivores existing in the ecosystem would be affected because competition for food would increase.

Answer:Conservation biologists, philosophers, environmental ethicists, and others offer several key reasons to conserve biodiversity. One argument is that organisms have direct economic value for humans. We use plants and animals for medicines, food, clothes, building materials, recreation, and other luxuries and necessities. But what if an organism that is of no use to us for food or hides is screened for useful medicinal compounds and found to have none? Do we sanction its extermination? Why must a plant or animal be of direct economic benefit to humans to have worth? Economic value alone is not the only reason to preserve biodiversity.
Another reason often given…to conserve biodiversity is that organisms, as components of ecosystems, provide services, and their interactions with other organisms contribute to the overall healthy functioning of ecosystems… On a practical level, biologists want to know just how much the loss of a few species will reduce the quality of services within a specific ecosystem. Two schools of thought prevail.
Answer:
Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. ... Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light.
This is a law because it is based on observations (Newton's Third Law)
