Xylem transports and stores water and water-soluble nutrients.
Phloem transports sugars, proteins, and other organic molecules.
The probability that an F1 plant will be tall when it is cross with a heterozygous tall pea plant when crossed with a short plant is 50%. This is because there is only one tall and one short. Therefore, the likelihood is kin to a coin flip.
Answer:
Fossils plays an important role in the field of biological study. It is because it acts as key evidence for the evolution that has been occurring on earth since the time of origin of earth.
These fossils are valuable as they are found to be embedded in the sedimentary rocks of about millions and billions of years old. The study of these fossils enabled scientists to understand how life evolved from single-celled organisms to the present day complex organisms. The initially occurring organism was comparatively small and soft-bodied, and so are rarely found. But in today's world, the organisms existing are much different and structured in a well-defined pattern, and this helped in the understanding of the evolutionary pattern of life on earth and also explains the key factors that are responsible for the occurrence of evolution.
Thus, these fossils are considered to be very much essential for studying biological evolution.
The answer is true. Adaptation allows for a better chance of survival.
Hope this helps!
