Answer:
The correct answer is: option D. all of the above.
Explanation:
In sexual reproduction, two opposite gender gametes are fused together to form a zygote by the process called fertilization which forms the new organism that is genetically unique.
In diatoms, sexual reproduction caused various types of advantages such as higher or enhanced genetic variability as recombination occurs. It also helps the ability to responding to environmental change Increasing the population or species size and other.
Thus, the correct answer is: option D. all of the above.
Answer:
6 CO2 + 6H20 + light – C6H1206+6 02
Explanation:
The conservation law states that the number of atoms stay the same before and after a reaction. Consider the following reaction:
6 CO2 + 6H20 + light – C6H1206+6 02
There are 6 atoms of carbon before the reaction, after the reaction also the number of carbon remains 6.
There are 18 atoms of oxygen before the reaction. The number of oxygen remains 18 after the reaction.
There are 12 atoms of hydrogen before the reaction. The number of hydrogen remains 12 after the reaction.
Hence, this reaction is the proper evidence of the conservation law.
Answer:
Transcription begins after replication and after transcription translation begins.
Explanation:
during Replication process in nucleus , the DNA is copied and replicated. the DNA will then be transcribed in to single stranded mRNA which will leave the nucleus and will go to ribosomes outside in the cytoplasm. here, the translation will take place in which the mRNA containing codons for genetic code will be translated in to proteins with the help of other types of RNA i.e tRNA, ribosomal RNA
The above answer is correct!
Answer: the research study lacked a control group, It was difficult to know individuals who are not taking Vitamin C and exposed to cold
Explanation:
Normally in a research study there should be a control group of the same age group like the study group in the same environment, <u>who will not Vit, C but </u><u>a placebo. T</u><u>o determine if Vitamin. C is the actual effective drug for prevention of cold in the study group or other factors.</u>
Therefore, in this study It was difficult to know individuals who were not taking Vitamin C and exposed to cold(control group) Because, it is the comparison of the data from the control group and the study groups that is needed to determine the efficacy of Vitamin C
