-The F1 generation has all yellow seeds.
-The F2 generation has yellow and green seeds.
Explanation;
Yellow seed color (dominant)
Green seed color (recessive)
P generation: In Mendel's experiments the parental generation.
Yellow seed color
F1 generation: In Mendel's experiments the offspring of the P generation
Yellow seed color and

b. All adults should engage in moderate-intensity aerobic physical activity for at least 150 minutes per week, vigorous-intensity aerobic activity for 75 minutes per week, or an equivalent combination of the two.
Explanation:
The Physical Activity Guidelines for Americans guidelines for older adults states that:
Older adults are more susceptible to cardiac and nervous disorders along with poor musculoskeletal strength.
To maintain good cardiac and nervous health; musculoskeletal fitness and strength; reduce depression, cognitive decline; older adults are directed to engage in moderate-intensity/vigorous or combination of both aerobic physical activities and muscle-strengthening exercises.
They should include physical activities combining one or more of; occupational (work-based) activities; transportation (walking, cycling); household chores (cleaning); leisure time activities (gardening, dancing); sports activities (hiking, biking, swimming, games, running) and planned daily routine exercise activities; all of them as part of their daily routines performed as an individual, family or community-based activities
.
Older adults with mobility issues should perform exercises to improve their balance and prevent falls

When comparing the birth patterns of humans and non-human primate, Rosenberg and Trevathan discovered some very clear differences:
1. The human period of labour and child birth is exceptionally long and painful compared to other non-human primates.
E.g. a human labour can last anywhere from 10-20 hours while that of a chimpanzee lasts only 2 hours.
2. Humans have the ability to walk straight, the trade off however is that it is extremely difficult and painful to give birth to a big brained human baby.
The answer on this scenario would be that most of the people would rely on external brains these days in order to connect to people.Hope this would be the answer on this question and would surely be of help then.
