Carmen conducts tests on a sample of four autotrophic organisms to determine the type of photosynthetic pigment present. Match the pigments to the species in which they are present. phycobilin sea lettuce phycocyanin diatoms chlorophyll b cyanobacteria fucoxanthin red algae

cyanobacteria - phycocyanin, phycobilin

diatoms - fucoxanthin

sea lettuce - chlorophyll b

red algae - phycobilin

Explanation:

- Cyanobacteria, which are also called blue green algae, are autotrophic organisms i.e. they perform photosynthesis by capturing light energy using pigments. They possess most of the blue phycobilin pigment called PHYCOCYANIN.

- Diatoms are algae under the division bacilliarophyta. They are single-celled photosynthetic algae which uses pigments that include FUCOXANTHIN, a type of xanthophyll pigment.

- Sea lettuce, belong to the group Chlorophyta and is autotrophic i.e. undergo photosynthesis. It makes use of CHLOROPHYLL pigments (chlorophyll b) like other plants.

- Red algae uses the red PHYCOBILIN called Phycoerythrin, which is an accessory photosynthetic pigment, to perform photosynthesis.

the answer is b

explanation:

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
