Question
Chapter 20, Problem 1STP
Summary Introduction
Introduction :
Autotrophic protists are like plants, utilize photosynthesis to produce food - they're considered as algae which involve red, brown, and green algae, as well as diatoms, euglena and dinoflagellates. Some algae have complex life-cycles. It is thought that plant life has developed from green algae.
Expert Solution & Answer
Answer to Problem 1STP
Correct answer :
The correct answer is option (A) Algae.
Explanation of Solution
Explanation/justification for the correct answer :
Option (A) Algae. Algae are the largest group of autotrophic protists. Algae have organized specific structures, found in aquatic environment, and photosynthetic in nature. So, the correct answer is option (A).
Explanation for incorrect answer :
Option (B) Protozoans. Protozoa are single-celled eukaryotes without cell wall and heterotrophic in nature. So, this is an incorrect option.
Option (C) Slime molds. Slime molds are a type of protists that form colonies and ingest bacteria, fungal spores, and other protists. So, this is an incorrect answer.
Option (D) Water molds. Water molds are a group of filamentous protists that physically resemble

- Molecular Biology Question Explain why the cell doesn’t need 61 tRNAs (one for each codon). Please help. Thank youarrow_forwardMolecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB.
