Explanation: because most animals eat to get the substances they need and breathing is also a big one if they don't breath they will die like the every being on this planet needs oxygen to live if we do not have those we will drop over dead.
Cross of true breeding dominant and recessive tomato plants will have:
Phenotype ratio in F1 generation is 4:0
genotype ratio in F1 generation is 4:0.
Explanation:
Data given:
Tall vine = dominant TT
dwarf vine = recessive tt
red fruit dominant RR
yellow fruit recessive rr
true breeding tall tomato plant bearing red fruit is TTRR
true breeding dwarf tomato plant bearing yellow fruit = ttrr
the cross is shown in punnet square:
TR TR
tr TtRr TtRr
tr TtRr TtRr
the phenotype ratio- 4:0
the genotype ratio - 4:0
The phenotype is tall vine with red fruit
Genotype is all the progeny are heterozygous dominant.
The primary function of the ovipositor in the majority of insects and fish is to release mature eggs from inside of the female body.
