If a plant’s leaves developed so that it’s vascular tissue only contained xylem how would this affect the rest of the plant’s physiological processes?

A) The carbon dioxide required for photosynthesis would not be absorbed and transported to leaf cells and photosynthesis would stop

B) glucose produced during photosynthesis in the leaf cells wouldn’t reach the rest of the plant and the cellular respiration in the plant’s other cells wouldn’t function

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
