ab is the answer please give me brainleist answer
Explanation:
Primary succession occurs when a habitat that has completely destroyed reheals from complete scratch
On the other hand, secondary succession occurs when only a portion of the original ecosystem survives and is rebuilt from that
The area residing in the center explains the bilatial tibulti, which precedents the bratuluti tubilitu. As for the rack itself, it has a half-moon (in laymens terms) axial, which appendages smoothly in all transition. The answer would certainty relate less to moving and a part itself, and more towards coordination or other terms (for which there are many), as this question is quite subjective.
In short, it has nearly free half-moon movement, though blocked in transition by its own quartsor axial.
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.
