If a homozygous short plant (tt) is crossed with a heterozygous tall plant (Tt), the percentage of tall offsprings is 50% and the percentage of short offspring is 50%.
- A heterozygous tall pea plant will have the genotype "Tt" and a homozygous short pea plant will have the genotype "tt" because homozygous means that both alleles are identical.
- Since 'T' is dominant over 't', any plant with at least one "T" allele will be tall (the dominant trait), regardless of what the other allele is.
- The punett square of the following problem will have 2 squares with Tt genotype and 2 squares with tt genotype.
Hence, the genotypic ratio of F1 generation will be
Tt : tt
1 : 1
And phenotypic ratio of F1 generation will be
Tall : Short
1 : 1

Answer:
In the gums
Explanation:
Lidocaine is a compound which can be used as a local anaesthetic. This anaesthesia works by blocking the voltage-gated channels which allows the influx of the sodium ions. As the sodium ions do not enter therefore an action potential is not generated in the axons as a result of which no pain is felt in the area.
In the given since the lidocaine is used by the dentist therefore the dentist in order to treat some dental problem must inject the lidocaine in the gums where the sensory receptors of the teeth are present.
Thus, in the gums is the correct answer.
The SARS-CoV-2 non-structural protein 1 (Nsp1), also referred to as the host shutoff factor, suppresses host innate immune functions. By combining cryo-electron microscopy and biochemistry, we show that SARS-CoV-2 Nsp1 binds to the human 40S subunit in ribosomal complexes, including the 43S pre-initiation complex and the non-translating 80S ribosome. The protein inserts its C-terminal domain into the mRNA channel, where it interferes with mRNA binding. We observe translation inhibition in the presence of Nsp1 in an in vitro translation system and in human cells.
Carbonates. Carbonation is a form a chemical weathering where the dissolution of limestone takes place. This is what forms the giant cave systems.
Answer:
Explanation:
Natural gas is most commonly extracted by drilling vertically from the Earth's surface. .Hydraulic fracturing, horizontal drilling, and acidizing are processes to expand the amount of gas that a well can access, and thus increase its productivity.
