Answer:
None of the above
Explanation:
There exist some protists which are autotrophs such as green algae others are heterotrophs such as amoebas and paramecia but known of protists are eukaryotes, they are all prokaryotes. Don't forget concepts, eukaryotes have a true nucleus and other memebrane bound organelles such as mitochondria and since protists lack such structures, they cannot be considered as eukaryotes.
I just took the test and it said the correct answer is true
Answer:
Due to suitable conditions.
Explanation:
Large population of bacteria can be maintained in the light organ to produce light by providing suitable conditions for growth and development in the organ. The luminescent genes are off when the organ has low cell density while on the other hand, when the density of cell is high in the light organ the luminescent genes automatically turned on and light up the organ. These Vibrio fischeri needs habitat and food for their growth and survival which is provided by the squid. If there is sufficient food for the squid, the population of Vibrio fischeri increases in the light organ.
Answer:
genes from the nucleus of a eukaryotic algal endosymbiont
Explanation:
Given: Chlorarachniophyte and cryptophyte algae contain three sets of genetic material: the nuclear genome, the chloroplast genome, and a set of genes found in the nucleomorph.
Here, nucleomorph genes represent genes from the nucleus of a eukaryotic algal endosymbiont
Secondary endosymbiotic acquisition of photosynthesis results in the transitional forms - Cryptophyte and chlorarachniophyte algae.
