Answer - Mainly RNA Molecule
Reason - Reason is it needs an information is important to the development and synthesis of protein.
Answer:
c. individuals of a single species that live and interact in one area
Explanation:
When some organisms belonging to a single species live together in an area, they make a population. Since members of a population belong to the same species, they are able to interbreed among themselves to produce viable and fertile progeny. They have the same resource requirement and interact with each other. All the plants of <em>Mangifera indica</em> present in an area make a population. Likewise, a group of <em>Panthera tigris</em> living in a forest together makes the tiger population of that area.
Answer:
Double fertilization produces a diploid sporophyte and a triploid endosperm. (Ans. C)
Explanation:
Angiosperm are plants which is known for flowering plant on the earth. The flower is reproductive parts of the angiosperm plant. They are including 4 basic parts of the flower: Carpel, Stamens, Sepals and Petals.
During angiosperm plant reproduction, 2 structure are formed which are known as the Endosperm and a Zygote. Later a Zygote will grow and form a embryo and the endosperm is known for food source of plant embryo. Endosperm and Zygote forming process is known as double fertilization and it is a unique process found in angiosperms.
Steps involved in double fertilization are:
1) The pollen tube processing to release 2 sperm cells into an unfertilized ovule.
2) When one sperm cell fuses with the eggs to the formation of zygote and another sperm fuses with the 2 polar nuclei to the formation of endosperm this process is known as double fertilization.
3) After the completion of double fertilization, a fruit and seed develop.
