Ques: Q: If pollination and fertilization occur, a diploid zygote forms within an ovule, located where Read this paragraph and choose the correct option from the provided answers: If pollination and fertilization occur, a diploid zygote forms within an ovule in the ovary. The zygote develops into an embryo inside a seed, which forms from the ovule and also contains food to nourish the embryo. The ovary surrounding the seed may develop into a fruit. Fruits attract animals that may disperse the seeds they contain. If a seed germinates, it may grow into a mature sporophyte plant and repeat the cycle. Choices: - bladder - uterus - testicle - ovary A:
Ans: ovary

Ques: Q: The minimum amount necessary for self-sustained fission of a given nuclide is called what? Read this paragraph and choose the correct option from the provided answers: Not every neutron produced by fission induces fission. Some neutrons escape the fissionable material, while others interact with a nucleus without making it fission. We can enhance the number of fissions produced by neutrons by having a large amount of fissionable material. The minimum amount necessary for self-sustained fission of a given nuclide is called its critical mass. Choices: - its half-life - its molar mass - its activation energy - its critical mass A:
Ans: its critical mass
