The stomata of many cacti lie deep in the plants' tissues. This adaptation helps cacti reduce water loss by keeping the hot, dry wind from blowing directly across the stomata. The leaves and stems of many desert plants have a thick, waxy covering.
C) thick waxy cuticle.
Answer:
cells - tissues - organs - organ systems - organisms
Answer:
Parent 1 : AaBb
Parent 2: aaBb or Aabb
Explanation:
In this cross two genes are involved and they are duplicate genes with cumulative effect i.e. individually they show the same phenotype but when together, they produce a new phenotype. Here,
A_B_ = red
aaB_ = sandy
A_bb = sandy
aabb = white
The progeny in question has a white piglet (aabb) so it must have got a set of "ab" gametes from both parents. Since parent 1 has red phenotype it should also have one A and B allele. Hence its genotype is AaBb.
Parent 2 should also contribute an "ab" pair to white piglet and it has sandy colour which is produced by either an A allele or a B allele so its genotype should be Aabb or aaBb.
Explanation:
Protandry - Male reproduction organ/anthers androecia/ stamens mature earlier than female reproduction organ/ carpels/ stigma/ pistil/ gynoecium in a flower. (ii) Self sterility - pollen grains are sterile to stigma of the same plants or same flowers.

Answer:
Answer of the question is explaine dbelow.
Explanation:
Rho GTPases interact with a variety of effectors to control actin cytoskeleton
reorganization, cell shape, and cell polarity. RhoA regulates cell shape and adhesion by
the assembly of contractile actin microfilaments into stress fibres. Rho GTPases also
regulate proliferation and cell-cycle progression, especially GuS transition.
All the cells are about to enter mitosis means they cross GuS transition, a drug that is a
potent inhibitor of RhoA activity has no affect on the cell because these cells already in
G2 phase. So, all the cells appear to be in telophase.
So, the correct choice is A. all the cells appear to be in telophase.
