Answer:
Mitotic phase
Explanation:
Cell cycle is composed of interphase and mitotic phase. Interphase is aphase of cell preparation. It is subdivided into:
- G1 (gap 1 phase)-the cell grows and becomes larger
- S phase- replication of DNA, duplication of centrosomes
- G2 (gap 2 phase)-proteins and oranelles are made
Mitotic phase is phase of cell division, chromosomes are separated, daughter cell get identical sets of chromosomes. It is followed by cytokinesis-separation of cytoplasm. Stages of mitosis are:
- prophase-condensation of chromatin into chromosomes, the nuclear envelope breaks down, mitotic spindle formation
- metaphase-the chromosmes line up (metaphase plate)
- anaphase-the siste chromatides move toward opposite cell poles
- telophase-the nuclear envelope forms again, cell division is almost complete
It turns into a solid and if you melt it it becomes a liquid and if you boil it it becomes a vapor
Answer:
The correct answer will be option-C
Explanation:
The plant absorbs the sunlight to perform photosynthesis which helps produce the sugar molecule used by the plants.
The plants absorb maximum sunlight at two wavelengths that are red and blue wavelength by chlorophyll and other pigments. The efficiency of photosynthesis is also measured maximum at these two active wavelengths called action spectrum.
In the given question, since the efficiency of photosynthesis has been discussed which could be measured with the production of oxygen and consumption of carbon dioxide. The experiment performed by the Engelmann showed that aerobic bacteria got concentrated in the blue and red wavelengths as the output of the photosynthesis were observed maximum.
Thus, the selected option is the correct answer.
