Answer:
D. Tt with Tt
Explanation:
In the given question, the student wants to study the stem length in the plants which are controlled by the T (dominant) and t (recessive) alleles.
To study the monohybrid cross for the stem length, the student must cross the heterozygous forms of the gene for the trait as it will produce the mixture of variables of height.
cross- Tt x Tt
T t
T TT Tt
t Tt tt
1. Genotype TT - tall height
2. Genotype Tt- tall height
3. Genotype tt- small height
Thus, Option-D is correct answer.
CO2 is a compound.
Carbon is an element
Oxigen is an element, and together they make a compound: Carbon Dioxide
An antibiotic is a medicine, which is used to treat the infections caused by the bacteria. The antibiotics kill the bacteria generally by rupturing heir cell membrane or destroying their genetic materials, so that they cannot reproduce.
