Why did short plants reappear in mendel’s F2 generation?
Fudgin [204]

Answer:

Because the F1 plants all had a lowercase a/short plant allele, there was a 25% chance that two plants would contribute it to their offspring and they both did sometimes to make a aa offpsring.

Explanation:

All the F1 plants were heterozygous, so when they were crossed, the resulting genotypic ratio was 1 AA : 2 Aa : 1 aa.  As you can see, this is the first time since the parent generation that there is a aa genotype and short plant phenotype, so that's why short plants reappeared.

"Genetic power is far more potent than atomic power. And it will be in everyone's hands. It will be in kits for backyard gardene
Aleks04 [339]

Answer:

These facts are true and disturbing

Explanation:

Genetics is a discipline that has advanced incredibly in the last years. For example, by using the versatile CRISPR-Cas9 genome editing system, we are now able to insert literally any sequence into a given genome in vivo. The CRISPR-Cas9 is a technology that can be used in a regular molecular biology laboratory. It is expected this technique will enable in the near future to correct genetic disorders that have plagued mankind since times immemorial. However, genomic technologies like that could be used by malignant persons to hurt innocent people, thereby it is imperative that countries regulate their use.

Potassium has a half-life of 12 hours. What fraction of a 100g sample is left after 48 hours
EastWind [94]

Answer:

After 48 hours amount left = 6.25 g

Explanation:

Given data:

Half life of potassium = 12 hours

Total mass = 100 g

Mass left after 48 hours = ?

Solution:

Number of half lives passed:

Number of half lives = Time elapsed / half life

Number of half lives = 48 hours/ 12 hours

Number of half lives = 4

At time zero = 100 g

At first half life = 100 g/ 2 = 50 g

At 2nd half life = 50 g/2 = 25 g

At 3rd half life = 25 g/2 = 12.5g

At 4th half life = 12.5 g/2 = 6.25 g
