Answer the following question given this paragraph: Algae play significant roles as producers in aquatic ecosystems. Microscopic forms live suspended in the water column. They are the main component of phytoplankton. As such, they contribute to the food base of most marine ecosystems. Q: What is the main component of phytoplankton? Choices: - amoebas - seawater - cells - algae A:
algae
Answer the following question given this paragraph: The life cycle of all plants is complex because it is characterized by alternation of generations. Plants alternate between diploid sporophyte and haploid gametophyte generations, and between sexual and asexual reproduction. The ability to reproduce both sexually and asexually gives plants the flexibility to adapt to changing environments. Their complex life cycle allows for great variation. A general plant life cycle is represented by the diagram in Figure below . From the figure, you can see that the diploid sporophyte has a structure called a sporangium (plural, sporangia) that undergoes meiosis to form haploid spores . A spore develops into a haploid gametophyte . The gametophyte has male or female reproductive organs that undergo mitosis to form haploid gametes (sperm or eggs). Fertilization of gametes produces a diploid zygote . The zygote grows and develops into a mature sporophyte, and the cycle repeats. Q: Plants can reproduce sexually and in which other way? Choices: - spontaneously - genetically - horizontally - asexually A:
asexually
Q: Answer the following question given this paragraph: The rising air cools as it goes higher in the atmosphere. If it is moist, the water vapor may condense.

Answer the following question given this paragraph: Translation is the process of ordering the amino acids in the assembly of a protein. The word ribosome comes from ribo nucleic acid and the Greek soma (meaning body). Two Nobel Prizes have been awarded for work relating to the ribosome. The 1974 Nobel Prize in Physiology or Medicine was awarded to Albert Claude, Christian de Duve and George Emil Palade for the discovery of the ribosome, and the 2009 Nobel Prize in Chemistry was awarded to Venkatraman Ramakrishnan, Thomas A. Steitz and Ada E. Yonath for discovering the detailed structure and mechanism of the ribosome. Q: Translation is the process of ordering the amino acids in the assembly of a? Choices: - carbohydrate - vitamin - lipid - protein A:
**Answer**
protein
