Firstly, start by doing Punnett squares for each of the characteristics. Attached are the three Punnet squares, made by me, as they should look in end.
For each of the Punnet squares, one characteristic each, we find that half of the offspring will be heterozygous for that characteristic.
Therefore, according to the product rule, you should now multiply the quantity of heterozygous for each characteristic and then obtain the total part of the offspring that's fully heterozygous.

Ss×

Ll×

Rr=

SsLlRr
Total offspring×

=10
There is 10 plants in the total offspring that are heterozygous for all the considered three genes.
Answer:
age-graded
Explanation:
Age-graded influences are biological and environmental events that influence the dynamic interaction between an individual and their environment at certain ages of the individual’s course of life. They are events that are expected to occur in a particular setting based on chronological age. For example, depending on the cultural settings of an individual, an individual is expected to graduate high school at a certain age, or get married at a certain age. Another example is puberty and menopause which are biological influences that are age-graded.
Answer:
The correct answer is- Resistance
Explanation:
The ability of any organism in a population to tolerate a chemical like insecticide, pesticide or antibiotic which is designed to kill it or slow its reproduction is called resistance.
For example, the antibiotic resistance is seen in some bacteria like MRSA(Methicillin-resistant staphylococcus aureus). They gain this resistance because they have some variant traits in their genome which provide them resistance against these chemicals.
These individual are selected through natural selection when the environmental condition changes and become adverse. So the correct answer is resistance.
