The opening of the stomata is thought to have or involve
with an increase in regards with the osmotic concentration in terms of the
guard cells. The guard cells are the ones surrounding the stomata in which when
they are pressured, they are likely to grow small or big.
Answer:
Genetic or DNA tests on the offspring.
Explanation:
The DNA test performed on the offspring, revealed that there was only genetic material from the mother. Then we are at the presence of asexual reproduction, which is extremely rare in such a complex organism. This form of reproduction is called parthenogenesis, where there is no fertilization by the male.
Answer:
The correct answer will be option-A
Explanation:
Desert biomes are characterised by the presence of the arid conditions or with few or less amount of rainfall.
The plant groups called the bryophytes and pteridophytes are dependent on the water for their fertilization which allows completing their life cycle.
In the desert conditions provided in the question, the mosses and ferns survived for many generations as these plant groups produced sperms with flagella which helped the sperms to swim in the water provided by the 10-inch rainfall per year and reach the female gamete and fertilize the egg cell.
Thus, option-A is the correct answer.

Answer:
The bright color of butterflies is a discouraging factor for its prey
Explanation:
Butterflies and caterpillars are easily visible to its prey but still they do not eat any of them. This can be because of two factors –
a) The bright color of these organisms might be a factor that makes them uninteresting (intending to be tasteless etc.) for their prey
b) The bright color might be a signal to the bird indicating in advance of any harm associated with the butterflies/caterpillar feeding.
Hence , instead the Monarch butterflies have brightly colored orange wings with black patterns on them, making them easily visible to birds, the birds rarely eat the monarchs
