1) Your research team has discovered a new single-celled organism in the San Francisco Bay. By microscopy, you find that the organism contains mitochondria. Based on what you know so far, this organism could be:
Select one:
a. an animal, but not a plant, fungus or bacterium
b. a bacterium, but not a plant, animal or fungus
c. a plant, a fungus or an animal, but not a bacterium
d. an animal, plant, fungus or bacterium
e. a plant or animal, but not a fungus or bacterium

Your research team has discovered a new single-celled organism in the San Francisco Bay. By microscopy, you find that the organism has a cell wall (although you don't know yet what the cell wall is made of). Based on what you know so far, this organism could be:
Select one:
a. a plant, a fungus, or a bacterium
b. a plant or a fungus, but not a bacterium
c. a plant or a bacterium, but not a fungus
d. a bacterium, but not a plant or a fungus
e. a plant, but not a fungus or bacterium
3)
Which of the following components are common to ALL living cells? Check all that apply.
Select one or more:
a. plasma membrane
b. ribosomes
c. endoplasmic reticulum
d. cell wall
e. nucleus
f. mitochondria
g. RNA
h. DNA
Question-1,e is correct answer because mitochondria are present in plant and animal but not in fungus and bacteria.
Question-2,cell wall is outer protective covering which may be flexible or rigid . Cell wall is found in plants ,bacteria and plant so a is correct answer .
Question-3,DNA ,RNA, plasma membrane and ribosome are common to all.
Endoplasmic reticulum is found in eukaryotes like plants and animals.
Cell wall is not found in animals.
Nucleus is only found in eukaryotes not in prokaryotes.
Mitochondria is not found in prokaryotes

reviously unknown single-celled organism that lacks a nuclear envelope and cochondria has just been discovered. Which of the following cell components would this organism most likely possess? a) lysosomes b) actin filaments c) ribosomes d) endoplasmic reticulum e) all of these components are equally possible 6) Autophagy is a process by which: a) Human macrophages find and consume foreign invaders such as infecting bacteria in the human body b) Peroxisomes break down long chain fatty acids into shorter lengths that...
You are the shipboard biologist for an expedition bringing up samples from new sites discovered on the ocean floor. Which of the following novel organisms would you characterize as a likely protist? Select all that apply. Organism A. Within each single cell is a nucleus, plus several membrane-bound structures, some of which are green. Organism B. This organism is an extremophile found in deep sea hydrothermal vents. DNA is localized to a nucleoid region of the cell. Organism C. This...
