Answer:
All adult sponges are sessile, meaning they are attached to some surface. Since they cannot move, sponges cannot pursue their food. Instead, they are filter feeders, meaning they obtain their food by straining the water for small bits of food like bacteria, algae, or protozoans.
Explanation:
O Cell membranes with ester-linked fatty acids are found in both Archaea and Eukaryota but not in Bacteria.
The composition of cell walls is similar in Archaea and Eukaryota but not in Bacteria.
The single-celled prokaryotic cells of Archaea and Eukaryota are visually similar, but Bacteria is not.
B. A late-night comedian using a photo as part of a political joke
C. A sports fan using player photos to sell souvenirs at games
D. A teacher using a photograph in a presentation to his class
Answer:
C. A sports fan using player photos to sell souvenirs at games
Explanation:
The situation least likely to be fair use is a sports fan using player photos to sell souvenirs at games.
The situation that is least likely to be fair use is option C, where a sports fan is using player photos to sell souvenirs at games. Fair use allows for limited use of copyrighted material without permission from the rights holder, but in this case, the sports fan is using the photos for commercial purposes, which is less likely to be considered fair use.
On the other hand, options A, B, and D are more likely to be fair use. In option A, a journalist is using a video clip in a report on a government meeting, which could be considered fair use as it is for educational or informational purposes. Option B, where a late-night comedian uses a photo as part of a political joke, could fall under fair use as it is for commentary or criticism. Option D, where a teacher is using a photograph in a presentation to his class, could also be considered fair use as it is part of an educational setting.

B( KIll infected cells
C( Send signals to increase immune cell formation
D( kill the pathogen
a prokaryotic cell that can make its own food
an aerobic bacterium
an anaerobic bacterium
Endosymbiotic theory or symbiogenesis is the evolutionary theory. A eukaryotic cell that can make its food will arise from a cyanobacterium. Thus, option a is correct.
Endosymbiotic theory is the evolutionary theory of the origin of the eukaryotic organism from a prokaryote cell. It was formulated based on the mitochondrial DNA and the chloroplast organelle in the plant.
According to the symbiogenesis theory chloroplast and mitochondria were once free-living that got phagocytized by another cell. So, if a cyanobacterium is engulfed then the eukaryotic cell will have the power to produce its own food.
Therefore, the eukaryotic autotroph will be produced from the cyanobacterium.

Answer:
A
Explanation: a eukaryotic cell that can make its own food
Answer:
More and more of the medium ground finch population would develop the characteristic of having a thick beak for breaking larger seeds. It would be a small amount of them having the characteristic at first, but then gradually the amount would increase until all of them keep this characteristic.
This is an example of natural selection and adaptation. The two words are related, in a way. Natural selection is when a species change over time with a characteristic that helps them adapt better to their environment. The medium ground finch population has to adapt in the change of environment through natural selection of getting the characteristic of thicker beaks for bigger seeds. Developing this characteristic will help more survive and reproduce, allowing the natural selection process to take place easier and quicker.
