The picture above shows CO2 molecules and how they interact with heat coming from the Earth. What usually happens when heat (red lines) hits a CO2 molecule
(red/black particles)?
Most heat bounces off the CO2 molecules and goes to outer space
Most heat bounces off the CO2 molecules and returns to Earth
Most heat passes right through the CO2 particles and goes into outer space
Most heat passes right through the CO2 molecules but runs out of energy,
returning to Earth

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.

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.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
