Answer:
1. Phenotype ratio = 3:1
Genotype ratio = 1:2:1
2. Phenotype ratio = 4:0
Genotype ratio = 4:0
3. Phenotype ratio = 1:1
Genotype ratio = 1:1
Explanation:
According to this question, a gene coding for tallness is involved. The allele for tallness (T) is dominant over the allele for shortness (t). The phenotype and genotype ratio of each parental combinations is given in the attached punnet square.
1. Tt × Tt
In this cross, both parents (Tt) will produce T and t gametes. Using this in a punnet square, the offsprings will be as follows: TT, Tt, Tt, and tt. Hence, The phenotype ratio is 3 tall: 1 short while genotype ratio is 1(TT): 2(Tt) : 1(tt).
2. TT × tt
In this cross, TT will produce T gametes while tt will produce t gametes. Using this in a punnet square, all offsprings will be heterozygous "Tt". Hence, The phenotype ratio is 4 tall: 0 short while genotype ratio is 4 (Tt) : 0 (tt).
3. tt × Tt
In this cross, tt will produce t gametes while Tt will produce T and t gametes. Using this in a punnet square, the following offsprings will result: Tt, Tt, tt and tt. Hence, The phenotype ratio is 1 tall: 1 short while genotype ratio is 1(Tt) : 1(tt).
Answer:
The first type is the primary consumer, an organism that ONLY eats producers.
Explanation:
The first type is the primary consumer, an organism that ONLY eats producers. That means that primary consumers ONLY eat plants or algae. Examples include cows (who eat grass and hay) and many types of insects (who collect and use pollen or eat leaves on trees).
Answer:
This condition might have arised due to recent round of antibiotics that had killed the bacteria which live in his gut and had allowed a yeast species to grow.
Explanation:
Here, it is given:
- Man when showed up at a medical facility felt drunk but he had not ingested any alcohol.
- His blood alcohol has measured 0.37 which is many times a legal limit.
- Also he claimed that he is home brewer and that intoxication showed is without any consumption of alcohol.
So, this condition can be hypothysed as the man may be on dosage of antibiotics. Whwn human body intakes an amount of antibiotics it kills the bacteria which is present in oue gut and allows an yeast formation to grow there.
So, this might be hypothysed from the given situation.
This condition of his can be changed by putting him on probiotics and by keeping him on a low carbohydrate diet for a week and then recheck for this alcohol consumption test.
Surely, this condition will improve.
The major organ that you would find in the lymphatic system would be the spleen.
Answer: Hypotonic
Explanation: If a plant is placed in an isotonic environment the plant will be limp, and if placed in a hypertonic environment, the plant will lose water.
