The ability to carry out photosynthesis (using the energy in sunlight to make sugar)... A. would be a good item to add to the list of characteristics of life since there aren't any

non-living things that can do photosynthesis.

B. would be a good item to add to the list of characteristics of life because all life either

directly or indirectly gets its energy from the sun.

C. would not be a good item to add to the list of characteristics of life because not all

living organisms can conduct photosynthesis.

D. would not be a good item to add to the list of characteristics of life because someday in

the future, a non-living thing may be able to conduct photsynthesis.

E. Is currently one of the characteristics of life

Is currently one of the characteristics of life

Explanation:

One major characteristic of life is nutrition. Nutrition refers to the process by which a living organism obtains its food.

Photosynthesis belongs to the kind of nutrition called autotrophic nutrition. Autotrophs are living organisms that produce their own food from simple inorganic chemicals.

Hence, only living organisms can undergo nutrition and it is already one of the characteristics of life.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
