Answer:
The phenotypic ratio will be 3:1
Explanation:
As per this question there are two phenotypes for seed color, yellow and green. Both the parents are true breeding that means they are homozygous for this trait. Also, all the F1 plants have yellow seed color which clearly indicates that yellow seed color is a dominant trait while green is recessive trait.
The cross of true breeding plants as mentioned above is depicted as under:
Parents YY x yy
/ \ / \
F1 generation Yy Yy Yy Yy
So, as per the law of dominance because of the presence of Y allele, all these progeny will be yellow in color.
Next, when these F1 plants will be crossed, the result will be as under:
F1 generation Yy x Yy
/ \ / \
F2 generation YY Yy Yy yy
The genotypic ratio of F2 generation is 1:2:1
The phenotypic ratio of F2 generation is 3:1
It simply means that in F2 generation, 3 progeny which have allelic combination YY & Yy will be yellow colored while 1 progeny which has allelic combination yy will have green color.
Plants obtain energy through a process called Photosynthesis, in which the plant takes the suns's energy through the Chlorophyll, which is what makes plants green, and uses it to make sugars out of the carbon dioxide from the air and water.
Hope this helps, and have a nice day!
When you do that the fish will die. That is because it will take too much water in it and die from it, or rather, the fish's cells will take too much water in.
Answer:
Volcanic gases. (Ans A)
Explanation:
Ocean water is salty because of the presence of dissolved salt. When water contact with a rock it starts weathering processes and this process starts to dissolve the soluble elements such as sodium out of the rock.
In volcanic gases, lots of chlorine ions are present in the atmosphere, these ions easily dissolve with water and produce the large flux of chloride that splashes into the oceans. So, the most common source of chloride ions in ocean waters comes from the volcanic explosions.
The Kuiper belt is home to three officially recognized dwarf planets: Pluto<span>, </span>Haumea<span>, and Makemake. Some of the Solar System's moons, such as Neptune's Triton and </span>Saturn<span>'s Phoebe, are also thought to have originated in the region.
So the answer is Saturn
Thats what NASA will tell you, but they think the world is round so be careful when they give you "facts"</span>
