Answer:
During the creation of oocyte, 3 additional haploid cells are created that will not be fertilized these cells are called Polar bodies.
Explanation:
The process of formation of oocyte is known as the Oogenesis. The oogenesis is the formation of oocyte which is capable of being fertilized, and the process begins even before the birth of the child. The oogonia is a diploid cell which undergoes mitosis to form the primary oocyte.
The primary oocyte then undergoes first meiotic division forming the secondary oocyte. this secondary oocyte is haploid in nature and this would again undergo another meiotic division to produce 4 haploid daughter cells. One of these is haploid ovum with additional 3 cells which do not get fertilized. these additional haploid daughter oocyte cells are Polar bodies.
The sympathetic ganglia spreads the stimulus to all postganglionic sympathetic neurons.
The labelled diagram is attached below & the correct sequence is shown below:
4. Sun Heat - The heat of sun causes water to evaporate.
2. Evaporation- vaporization of water
6. Condensation - The conversion of water vapours from gaseous to liquid state.
1. Precipitation - water falls from clouds in the form of rain, snow or sleet.
5. Run off - The surface water is a major part of the collected water, flows from top of any surface (form rain, snow etc)
3. Collection of water - The rain water is collected.
Given the following choices
A. position of the carbon-carbon double bonds
B. presence of enclosed carbon atom rings
C. branching of the carbon chain
D. length of the carbon chain
The answers are; B, C & D. Carbon is a versatile atom (with a valence of +4) and is able to bond with other elements and other carbon atoms in different ways. It can form linear and branching chains of varying lengths. It can form double and single bonds with elements and form rings such as the deoxyribose sugars.
