Answer:
The correct answer is -
The genotype of offspring - 1:2:1 (YY:Yy:yy)
The phenotype of offspring - 3:1 (dominant trait: recessive trait)
Explanation:
In this question, it is stated that there is a cross between Yy and Yy. By the genotype of the parents, we can say that Y is dominant for a particular trait and y is recessive and the parents are in the heterozygous condition in this cross. The gametes these parents will produce are - Y and y and Y and y
then the cross of Yy and Yy would be -
Y y
Y YY Yy
y Yy yy
Offspring from this cross are YY, Yy, Yy, and yy which means the genotypic ratio is - 1:2:1 and the phenotypic ratio is - 3:1 as three out of four are dominant.
True
Explanation:
The water molecules move from areas of high concentration to areas of low concentration to make an equivalent between the two.
I hope this helps at least a little :D
Diffusion is the movement of particles across a semi-permeable membrane from a lower concentration to a higher concentration
Answer:
C. The concentrations of products and reactants are equal.
Explanation:
A reaction has reached equilibrium when the concentrations of products and reactants are equal.
The answer is D) Both produce oxygen
Hope this Helps!!!
