Answer:
1:2:1
Explanation:
If we cross heterozygous for all three trait with a plant that is homozygous with the greenpods. so:
See attachment:
Conclusion:
The Heterozygous for all three traits will be : 50%
heterozygous for short seed shape: 50%
Food handlers who does different cutting surfaces base on cutting raw vegetables and raw poultry, is trying to prevent contamination as doing this prevents food from being mixed and from being contaminated. It is also a way of having the food to be prepared properly and in a more sanitized way for people to eat.
It could affect a protein a few different ways:
1. If you get a switch of one nucleotide for another, this could (but not always) result in a different amino acid being inserted than was supposed to. So, for example, you were supposed to insert a methionine at AUG of the mRNA, but the mutation resulted in GUG which now codes for valine. This may disrupt the activity in the protein - either in proper folding or if in the active site of an enzyme could disrupt the activity.
2. Other swaps of nucleotides can result in shortened proteins - so if you were supposed to have tyrosine inserted at UAU and that got switched to UAA which is a stop codon, then the protein is too short - and may not fold or function correctly. Depends where the mutation is of course.
3. Of course take that further and perhaps you were supposed to have a stop codon (UAA) and that got switched to UAU...so now instead of stopping the protein synthesis you instead insert a tyrosine and the protein continues to be extended until another stop codon is reached...that could be disastrous for the function of the protein as it probably won't fold properly.
Explanation:
Convection drives the circulation of air in the earth's atmosphere. The sun heats the air near the earth's equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again.
Answer:
The correct answer will be option-B
Explanation:
Stromatolites are the sedimentary deposited mounds made of layers of phototrophic microbes which were usually present in the primordial times. The stromatolites are one of the oldest fossils is known today which were formed in the shallow water.
They are composed of the phototrophic bacteria or cyanobacteria which survived and still survive by using the carbon dioxide and sunlight to make food material.
Since the bacteria are the prokaryotic organism therefore, the Option-B is the correct answer.
