Answer:
All Offsprings will have a red flower and tall phenotype with a genotypic ratio of 1 RrTT : 1 RrTt
Explanation:
This is a cross involving two genes; one coding for rose color and the other for height in rose plant. The red allele (R) is dominant over the white allele (r) in the first gene while tallness (T) is dominant over shortness (t) in the second gene.
Based on this, a homozygous red and tall flower will possess a genotype: RRTT while a flower that is white and heterozygous tall will have genotype: rrTt. Hence, each parent's allele will separate into gametes independently of one another according to Mendel's law of independent assortment. The possible gametes combination are:
RRTT- RT, RT, RT, RT
rrTt- rT, rt, rT, rt.
Hence, using a punnet square (see attached image), all offsprings will possess the phenotypic dominant trait i.e. red and tall. The genotypes produced are: RrTT and RrTt in a ratio 1:1

D. HEARING is the sense most closely related to balance.
We maintain our balance through the detection of the movement of the fluid in our inner ear by hair cells.
Our inner ear has three semi-circular canals that are full of movable fluid and sensory hairs that are moved when the fluid moves. <span>These tell you which way your head and body is tilted in relation to gravity and give you information about movements and acceleration. Thy are also incidentally partially responsible for sea-sickness when the brain is fed conflicting information about the world from your ears and your eyes, the reason why you should get off your bed and go on deck to look at the horizon so the information matches.</span>
Answer:
It is due to the temperature of the star
Explanation:
The colour of star depends on the temperature of star.
False.This would cause species to be endangered. When a predator preys on a single prey, it might end up to over-hunting. This will cause a domino effect, if there are no more preys in the area, there is also a big tendency that the predators will die because of the lack of preys in the area, which will eventually lead to extinction of both species.
