D. Fertilization, diploid
During fertilization, the egg and sperm (haploid gametes) fuse and form a diploid zygote. The zygote has 2 complete sets of chromosomes, one from each parent.
Hope this helps!
Answer: pH 5 Acidic environment.
Explanation:
The fungi grows best in the acidic environment, this is because the fungi grows in a moist, warm and darker environment.
The fungus grows at lower pH. When the fungal species was grown in the laboratory conditions then under low pH, the fungal species grow more properly.
Hence, the best environment for the growth of fungus is pH 5.
Answer:
C
Explanation:
The production of ATP is greatest at 50o C as indicates by the production of CO2 in the Krebs Cycle
1) Interphase is the longest phase and most of the cells are present in that very stage !!
2) Interphase is the longest phase and Anaphase is the shortest phase !! Interphase is the longest phase as in this phase the cells prepare themselves for dividing and it takes most of the time for gathering energy for division ; in this phase DNA also replicate !!
3)
Interphase: DNA replicates;
Prophase: Nuclear membrane starts disappearing and Centrioles go on opposite poles !! DNA condense to form Chromosome.
Metaphase: Chromosome attach to spindle fibre and starts to move to equitorial plate.
Anaphase: Centromere divide and half the chromatid goes on either pole
Telophase: Nuclear membrane starts to reassemble; Chrmosome goes to normal uncoiled state ; Other organelles starts appearing
Cytokinesis: Cell furrow forms and cell divides into two half.
4) In dividing cell nucleus membrane is absent while in non dividing cell the membrane is intact
5) Tip of the onion root is meristamatic cell which divides but if it is permanent cell ; there would be no division !!
