Please help! punnet square and shouldn’t be hard! thank you

In the resulting offspring the correct proportions are for the genotype 1:1 and for the phenotype 1:1 (first option).

Explanation:

According to Mendel's Laws, the product of the cross between a heterozygous individual and a homozygous recessive for a character will always be a hybrid or recessive offspring as the Punnett square shows on image.

For the character -tall and short- of the pea plant:

Alleles    t         t

T           Tt        Tt

t             tt         tt

For the genotype: probabilities that in the offspring there are hybrid individuals with genotype Tt is 50% and recessive tt 50% .

For the phenotype: the probabilities of tall plants in the offspring are 50%, and 50% short plants.

A 50:50 ratio, for genotype and phenotype, is equivalent to saying that both phenotypic and genotypic ratio is 1:1.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
