Answer:
In this case, the question asked is "To what lengths must we go to protect plants and animals?", which is not specific and cannot be used for scientific research.
The ecological researches for the safety of the environment involves the protection of the plants and the animals on the basis of their number and vulnerability to extinction. Almost all the length of the plants are ecologically important and can decrease in number due to the changes in the environment, the length is not a parameter to determine the protection boundary.
The cell membrane is semi permeable in nature, that is, it allows the passage of some substances while it disallows some substances. Small and non polar molecules pass quite easily through the cell membrane but large and polar molecules can not do this.
The substances which can easily pass through the cell membranes make use of passive transports such as diffusion and facilitated diffusion to enter the cells while substances which can not pass through the cell membranes on their own make use of active transport. Examples of active transport are endocytosis and ectocytosis,
Answer: fossils can be formed only when a living thing is buried soon after it dies. If it is not buried soon enough, it decays. For this reason, most fossils are found in sedimentary rocks that were once under water.
