<span>A cell can only grow so large in size because its
ability to exchange materials is affected by a growing surface-to-volume ratio.
Nature designed cells to be small in size because of the network of membranes
passing through it. If cells grow any bigger, membranes in it will not be able
to pass through its different parts and perform their purpose.
A cell is a network composed of many organelles (e.g. mitochondria, nucleus),
that communicate and work together to provide bodily functions. The cell is
small so that communication between organelles will be faster and much easier. When
cells are small they can be easily repaired when damaged and replicated when
needed.</span>
Answer: C. M. rupestris, M. eastwoodiae, and M. nelsonii; they put more energy into making rooted branches than they put into making nectar and seeds.
Explanation:
In asexual mode of reproduction the plant does not produce gametes. The plant reproduce through vegetative propagation or spore formation. The plant does not produce nectar as no flowers are produced to attract the pollinators.
In sexual mode of reproduction the plant will develop the gametes and flowers will produce the nectar to attract the pollinators.
Thus on the basis of above explaination, C is the correct option. As the plants will invest more energy in making roots which are the organs for vegetative propagation a process of asexual reproduction.
The tissues found within the vein if I must say are xylem and phloem. Glad I can help.
Explanation:
The modern theory of chemical evolution is based on the assumption that on a primitive earth a mixture of simple chemicals assembled into more complex molecular systems, from which, eventually came the first functioning cell(s).
I believe the correct answer is A
