Use the following information for this question: Phenylketonuria is considered to be an inborn error of metabolism. It is a rece

ssive genetic condition in which the enzyme that breaks down the amino acid phenylalanine is defective or missing. Testing of all newborns allows this condition to be detected at birth. A special diet that severely minimizes phenylalanine (e.g., by avoiding diet sodas and most usual sources of protein) can treat the condition. In this scenario, two carriers of both cystic fibrosis and phenylketonuria have a child. What is the probability that the child will have cystic fibrosis and be a carrier for phenylketonuria

How did Mary Montagu discover a vaccine for smallpox
insens350 [35]

Answer:

Lady Mary Wortley Montagu adapted "variolation" instead of "vaccination" to prevent smallpox in her children. She learned about it when she was in Constantinople (Turkey) with her husband. There, prisoners were intentionally inoculated with smallpox virus under their skin. When she saw that they didn't develop the disease and were among survivors, she inoculated smallpox virus to her children (son and daughter) as well using a needle. Later on, efforts of Edward Jenner towards vaccination were also recognized and it became a fashion to inoculate smallpox as a preventive measure.

gayaneshka [121]

Answer:

multidimensional

Explanation:

Development is multidimensional

By multidimensionality, we mean a complex and dynamic interaction of factors that control development all through the lifespan, it as to do it biological, cognitive, and socioemotional changes.

Let's take for instance, in adolescence, puberty comprises of physiological and physical variations with variations in hormone levels, the formation of primary and secondary sex characteristics, changes in height and weight, and varying other bodily alterations. The cognitive changes (increment in thinking- abstractly), emotional and social changes (controlling emotions and relationships with equals, falling in love).

Puberty deals with a wide range of domains that exemplifies the multidimensionality component of development.

You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype? Conduct a
Archy [21]
The answer is <span>Conduct a test cross with a purebred recessive plant. 

</span>

Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.

<span>Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant. </span>

If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.

<span>According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).</span>
