Answer:
Gametes that will be produced are:
YST, YSt, YsT, Yst, yST, ySt, ysT, yst
Explanation:
From YySsTt, it is obvious that as there 3 type of genes.
The number of gametes = 
= 8
5 genes = 
= 32 genotypes
10 genes = 
= 1024 genotypes
20 genes = 
= 1048576 genotypes
Theres monocotyledons and dicotyledons. (1 and 2 cots)
the answer should be monocotyledons, we can see that through the leaves and the petals. monocotyledons the petals r usually in the multiples of 3 or 6, and 9 petals is the multiple of 3. also, monocots leaves r usually in parallel leaf veins, so your plant is monocotyledons, which means one.
just in addition, dicots petals r in multiples of 4 or 5, and their leaves r usually in branched veins
A more clear understanding of the world around us.
Answer:
Tundra
Explanation:
Ocean is the most stable biome, provides the majority of earths food and oxygen.
Rainforest provide 20% of earths food production. Also stable.
Grasslands although the don't get much rain it doesn't compare to the harsh weather that Tundra's face.
Tundra's is a very fragile environment. The freezing cold temperatures makes it a very difficult environment to survive in the winter, and plants and animals have a hard time coping with any extra stresses and disturbances. Therefore making it the least stable out of the rest listed.
How does a new hypothesis replace an older explanation of something in the natural world? To understand this let us look at one of the classical example of geocentric theory and heliocentric theory. The geocentric theory states the Earth is at the centre of the solar system and the Sun, Moon, and all the other planets revolve around it. This ancient theory failed to explain the phenomenon like the phases of Moon, solar eclipse and lunar eclipse. The modern heliocentric theory which states that the Sun is at the centre of solar system, and all the planets including the Earth revolve around it. This theory was able to explain all the phenomenons unlike the geocentric theory. Hence the heliocentric theory replaced the geocentric theory.
