Systematic error affects the measurement in a constant way and represents stable factors that affect the observed score in the same way each time the measurement is made. Systematic error is a steady, repeatable error joined with faulty measuring equipment or an imperfect experiment design.

20 overall, around ___________ teenagers contract an sti sexually transmitted infection) each year.
Sauron [17]
<span>overall, around twenty million teenagers contract an STI (sexually transmitted infection) each year. </span>(The half of them are from U.S.)<span>

A sexually transmitted infection (STI) is an infection that is transmitted between partners during different forms of sexual intercourse. This infection can lead to an infectious disease, formerly called venereal disease (the name comes from Venus, goddess of love)All sexual practices that involve mutual genital or oro-genital contact with another person, or genital fluids, are considered to carry a risk of transmitting an STI. Each STI has a different risk and severity.

I need help with these
snow_tiger [21]

Answer No 1:

The trait which is being studied in the cross is the height of the pea plant.

Answer No 2:

The two alleles for this trait are tall height allele which we can write as T and the allele for short height which we can write as t.

Answer No 3:

The allele for tall height is the dominant allele. We can say this because when a cross between a dominant homozyous and a recessive plant were made the offsprings resulted in the tall plants which is the F1 generation in the figure. As a dominant trait masks the recessive trait, hence we can say that the tall height allele is dominant over the short height allele.

Answer No 4:

The allele for short height t is recessive because as we can see the short height trait is being masked by the tall height trait in the F1 progeny. In F2 progeny, there are more number of tall height plants produced which further prove that short height is the recessive trait.

Answer No 5:

The F1 offsprings will have a dominant tall height allele, T, and a recessive short height allele, t. The dominant allele was inherited from the tall parent and the short height allele, t, was inherited from the recessive parent.

We can say that because the F2 progeny shows some plants to have short heights which is only possible if the F1 generation has heterozygous dominant (Tt) alleles.

Musya8 [376]

Note about the question:

Probably there are options for this question, but I failed in finding them. However, in the explanation box I will explain the reason for the lack of white flowers in the F1.

Answer:

The purple phenotype is dominant over the white phenotype. The allele that expresses the purple color is dominant and, in a heterozygous state, hides the expression of the recessive allele that expresses the white color. Principle of dominance.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.
