Question 1

Explain the features necessary for both brown algae and dinoflagellates to be classified in the supergroup SAR.

Accepted Answer

Brown algae will have chlorophyll a and c as well as an accessory pigment that gives them their brown color.They will also store their food in the form of laminarin.Sizes can range from small forms to large multicellular ones.
Dinoflagellates are unicellular,photoautotrophic algae that are encased by a shell of cellulose and silicate plates.They also contain chlorophyll a and c and an accessory pigment that gives them their brown color.

Question 2

The human body generally forms antibodies ("immune chemicals")to foreign substances detected in the blood plasma or in interstitial spaces within a short time.Explain why the malaria organism,unlike "short-lived" influenza and other infections,can survive in the human host to cause recurrent chills and fevers for years.

Accepted Answer

The malarial parasite has two hosts,both the mosquito and humans.In humans,the parasite spends most of its time inside liver and red blood cells,hiding from the immune system.Some species may remain dormant in liver cells for extended periods of time.
