For Plato users...
A. It is a special kind of elliptical orbit.
5. Adenine and thymine base pair
6. Chargaff's base ratios
10. Hydrogen bonds exist between base pairs (A/T and G/C) allowing DNA to maintain the helical structure. Adenines and thymines have two hydrogen bonds, guanines and cytosines have three. When these hydrogen bonds are broken, this allows for "unzipping" of the DNA - which can then be replicated, transcribed/translated to RNA, etc.

Answer:
b) Forming zygots
Explanation:
A zygote can be defined as a eukaryotic cell formed by the fusion of gametes during sexual reproduction. In general, a zygote is a diploid (2n) cell produced by the fusion of two haploid (n) gametic cells (eg., in mammals, sperm and egg cells). In multicellular organisms, the zygote is the first stage of development, which will give rise to an adult organism as it divides and grows. A zygote cell can be considered as a pluripotent stem cell because it differentiates into all cell types.
Answer:
Light-dependent reaction of the photosynthesis takes place in the thyllakoid membrane of the chloroplast. It converts solar energy into the chemical energy (ATP and NADPH) which is then utilized in the light-independent reaction to fix carbon into glucose or food.
The correct order of events that take place during light-dependent reaction would be:
Energy from the Sun ejects electrons from chlorophyll and splits water molecules to yield hydrogen ions.
↓
Electrons move down the electron transport chain, releasing energy that pumps hydrogen ions into the thylakoid space.
↓
The concentration of hydrogen ions in the thylakoid space increases.
↓
Hydrogen ions diffuse across the thylakoid membrane into the stroma through ATP synthase.
↓
ATP synthase uses the energy released as hydrogen ions move from regions of high concentration to regions of low concentration to make ATP.
