It looks right I looked over it and it looks good
Answer:
1. nutrient recycler
2. mutualist
4. parasite
Option C
Explanation:
Nutrient recycler: The bacterial decompose the dead plant and release the organic elements back to soil or air. The organic matter present in the dead plant parts is decomposed and the carbon is released into the air. Similarly, other nutrients stored in the dead plant are decomposed by the bacteria and are released into the environment so that they can enter the nutrient cycles.
Mutualist: The bacteria living on the surface of leaf obtains nutrition from it. The plant is benefited by this association since the bacteria prevents the invasion of other pathogens in the plant. An ecological interaction wherein both the species are benefited is called mutualism.
Parasite: Once the bacteria enter the leaf, it causes disease to the plant. Here, the plant is the host while the bacteria is a parasite. The plant is harmed while bacterial obtains nutrition from the plant.
They use their bristle like teeth called baleen. They filter out krill.
Answer:
Nucleus
Explanation:
In eukaryotic cells, the nucleus is a membrane-bound structure that contains the genetic material, which is expressed in response to cell stimuli (i.e., environmental stimuli). This genetic material consists of genes that are expressed in response to cell signaling events. For example, the transcription factors that are found in the cytoplasm are activated after receiving a signal from receptors localized in the cell membrane, when these membrane receptors bind to specific signaling molecules. Subsequently, these transcription factors are translocated into the nucleus to interact with DNA promoter regions in order to activate the expression (transcription) of target genes capable of responding to an environmental stimulus.
