Answer:
The correct answer is - Trains can have inconvenient schedules, but produce less pollution than cars do.
Explanation:
Trains are expensive to build and also required land for making routes and stations and platforms for passengers but that can be reimbursed by fare in a longer time period.
Trains also produce pollution but in comparison to cars these are way less contribute to the pollution, However, these are not convenient as they start and reach at a specific time and also sometimes not comfortable like cars.
Last option sorry if it’s wrong bae
Answer:
The correct answer is -
Parent 1: RW, Parent 2: RR
Explanation:
In the given punnet square there are four offspring and it is a monohybrid cross between parent 1 and parent 2. The four offspring produced in this cross have RR, RR, RW, and RW alleles. By the genotype of the offsprings, it is clear that there are 50 percent pure or true-bred and 50 percent are heterozygous.
Each parent contribute two alleles and these alleles are independently assort in the zygote to form offspring so there must be R, R, R and W allele present in the parent
Parent 2 → R R
Parent 1 ↓ R RR RR (one allele (R) come from each parent in zygote)
W RW RW (one allele (R and W) come from each parent)
