50 percent of the offspring would be expected to have the ability to roll their tongues If a heterozygous male is crossed with a homozygous recessive female.
Explanation:
Information given:
the ability to roll tongue is dominant, the genotype would be RR, Rr
the inability to roll tongue is recessive trait the genotype = rr
Given that heterozygous male is crossed with homozygous recessive female, the genotype is
Rr X rr
Punnet square shows that:
R r
r Rr rr
r Rr rr The genotype ratio is 1:1
phenotype ratio is 1:1
There are chances of 50 % offspring having the ability to roll their tongues as they are heterozygous and have the dominant allele for rolling of tongues.
Answer:
Internally in the female
Explanation:
internally in the female because that's where the sperm meets the egg
I'm not entirely sure on this one... But I think it's 1. cell division helps animals repair old cells..
like please
Your question isn't the most clear, but I think your answer is rocks, or more specifically phosphorous rich rocks because the phosphorous will mix with the sediments on the river's/lake's ground forming phosphorous rich rocks.
That means that It'll become a phosphate mineral and later become phosphorous again when the minerals weather.
Hope it helped,

The answer is : The rock cycle is driven by energy from the Sun as well as from the interior of Earth. The sun provides energy for surface processes such as weathering, erosion, and transport. This is the one of the major source of energy for the rock cycle. Weathering happens when there is a interaction with the air, water and organism which cause the rock to break down, and the pieces of rock are carried away by wind, moving water, etc. through erosion.
