An organism that contains foreign DNA, which was inserted into its own genetic material, is called transgenic.
Answer:
Going by the definition, pioneer species are hardy species which establish themselves in a disrupted ecosystem and trigger the process of ecological succession. These include species like algae, lichens, and mosses, which grow in poor, nutrient-deficient soil, and put up with extreme conditions with immense ease. Most pioneer plants are annuals, i.e., species with a life-cycle of a year, which eventually give way to the emergence of perennials.

The question is incomplete as it does not have the options which are:
A.) Presence of genitalia.
B.) Shape of genitalia.
C.) Presence of a scrotum.
D.) Composition of accessory fluids.
Answer:
Option-A
Explanation:
The reproductive system which is the system formed by the organ which is involved in the reproduction in an organism. These reproductive organs are known as genitalia. Since reproduction is one of the criteria of the cellular organisms, reproduction is possessed by all the organisms on Earth.
The animals which bear the reproductive structures therefore always show the presence of both internal and external reproduce organs like testes, Vas deferens as internal organs and penis and scrotum as external organs.
Thus, Option-A is correct.
Answer:
Plants exhibit a gametophytic (haploid) cycle, while humans tdo not have an alternation of generations. The plants have a sporophytic (diploid) stage of multicellular development which is similar to somatic development in humans. Finally, this sporophyte produces haploid spores that grow into a gametophyte, thereby repeating the cycles of life.
In regard to the fertilization: the gametophyte (asexual) produces haploid gametes that form a diploid zygote analog to the zygote in animals and humans
Some organisms in a population are better equipped to survive than others.
