Answer:
The parents must be Tt, Tt
Explanation:
Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:
T t
T TT Tt
t Tt tt
We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).
This means that the parents must be Tt, Tt.
Answer:
Homeostasis
Explanation:
Homeostasis mean to 'keep the conditions of the internal environment of the body relatively constant'. The person drinks a glass of iced water which cools the internal environment that responding in decreased sweat production.
Photosynthesis and Cellular respiration are the processes responsible for keeping the percentage of atmospheric oxygen at relatively constant levels in plants. Without these processes within the plant cells, the plant will not be able to survive. These processes are responsible for nutrient transport and oxygen transport within plants.
