Rotational movements need the most thoracic mobility. This is because a rotational movement (such as twisting) because the movements are more three dimensional, and this is where the most can go wrong. For example, if you were holding a 35lb child and simply bent forward to put him/her down, this is less likely to cause injury than if you were to twist your torso to the right and put the child down. There is a lot more spinal stability and mobility needed for the second motion than the first.
Answer:producing sex gamete
Explanation:
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.
