Which of these is unique to flowering plants? a. an embryo surrounded by nutritive tissue b. haploid gametophytes c. double fertilization d. pollen production e. a dominant sporophyte generation

:

Double fertilization

Explanation:

In flowering plants, one sperm nucleus fertilizes the egg and other sperm nucleus fuses with two other nuclei found within the ovule—thus forming triploid endosperm.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
