Answer:

Sea turtles are now facing much greater challenges as a result of climate change. Coastal ecosystems will be eroded and damaged as sea levels rise and storms become more strong. Warming ocean currents could expose sea turtles to new predators while also damaging the coral reefs that some of them depend on to survive.

You live in a city in Florida on the Gulf of Mexico and are trying to figure out why the water at the beaches turned bright gree
Anestetic [448]

Blue-green algae affect freshwater, and it has a direct correlation to agricultural and urban runoff.

The heavy rains last spring most likely caused Lake Okeechobee to discharge water containing blue-green algae into rivers and canals. The bright green sludge oozed onto docks, dams and rivers and through tributaries into the ocean.

Blue-green algae (cyanobacteria) are a group of prokaryotic, autotrophic microorganisms that contain the photosynthetic pigments (chlorophyll and phycocyanin), Therefore, the DNA shows bacteria

Bacteria is the correct answer

How does the escape velocity of venus compare to that of mars?
Olenka [21]
In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy. 
This relates to the speed at which an object should travel to "break" free of any gravitational pull.
Venus: 10.46 km/s
Mars: 5.027 km/s

Starch, cellulose, dextran, and glycogen are polysaccharides. How are they similar? To what are their different properties due?
daser333 [38]

Answer:

similarity

Starch, cellulose,dextran and glycogen are all polymers of glucose

differences

                monomer/glucose     glycosidic bond    branching

1.starch              α glucose          1-4 and 1-6               branch and unbranced

  amylose                                       1-4                          unbranched

  amylopectin                               1-4 and 1-6              branched

2. dextran          α glucose          1-6                           branched

3. cellulose        β glucose           1-4                          unbranched, linear        

4. glycogen       α glucose           1-4 and 1-6              branched (shorter

                                                                                     branches than starch)

Enzyme: amlase acts on starch and cellulase acts on cellulose as they are specific for their substrates.

Explanation:

Starch: Consists of both branched amylopectin and unbranched amylose

Enzymes: Enzymes are specific as the gulcose molecule in starch is α and in cellulose is β which differ in their position of hydroxyl groups at anomeric carbon, their structures differ so they form different bonds. Active sites of enzymes can act only on specific bonds a sthey can fit to their specific substrates.
