A. RbOH is a base because its pH is greater than 7.
This statement is correct and points at the compound being a base because an Alkali always has a pH between 7 and 14. Starting from 7 which is a neutral compound neither acidic nor alkaline, the higher the pH value, the stronger the compound is an alkali or a base. The strongest pH compounds are those that have the pH value of 14 and the weakest alkalis are those the pH value of which is closer to 7.
None of the other options fit this criteria.
Answer:
A plant’s ability to photosynthesize depends on a variety of factors, including the amount of available sunlight. Plants also go into a protective mode after an environmental crisis, which helps protect the plants’ chloroplasts from damage. During this period, photosynthesis is low. The technique used in this research improved the plants’ ability to recover after a crisis, boosting plant growth and crop yield. This research could ultimately lead to growing crops successfully in different types of environments and in a shorter period of time.
Negative ways humans can spoil the environment is 1.using too much carbon like in cars,power plants, and green house. 2. littering and dumping trash or oil in the waters or land. 3. over fishing or some times over hunting and even poching. positive effect is 1. they have try to clean the waters and land.2. there are patrols to watch people from over fishing or hunting 3. they are trying to reduce the amount of carbon used in the air.
