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:
This new food is a carbohydrate
Explanation:
<em>Carbohydrates (also known as saccharide) general formula is CH2On, this means they are molecules that only contain carbon (C), hydrogen (H) and oxygen (O). </em>In the basic form, these sugars are known as monosaccharides, they can combine no form more complex sugars like disaccharide (2), oligosaccharides (2-10) or polysaccharides (>10).
Therefore we can conclude that this new food is a carbohydrate.
I hope you find this information useful and interesting! Good luck!
Answer:
My guess would be H₂O/ water, since osmosis is a form of passive transport and I can't see the model the question references. Gases like O₂/ oxygen, CO₂/ carbon dioxide, and simple sugars like glucose can also pass through a cell membrane with passive transport though.
