Answer:
What are specialized cells
The first answer is the correct one. Osmosis is only water and diffusion is everything else across a semi-permeable membrane.

In the energy pyramid for any given ecosystem, the most energy available is at the bottom and the least energy available is at the top.
At the bottom of the energy pyramid are the producers (plants and other photosynthetic organisms). The first group of organisms that consume the producers are called the primary consumers (herbivores). The next group of consumers are the secondary consumers, and then the tertiary consumers and quaternary consumers.
Correct Answer: B
Answer:
<u>Peroxisome</u> is not the part of endomembrane system
(<u>Mitochondria</u> and <u>Chloroplasts</u> are also not included in the endomembrane system)
Explanation:.
The endomembrane system is composed of the different membranes which are suspended in the cytoplasm within a eukaryotic cell. They include :
1) Nuclear membrane
2) Endoplasmic reticulum
3)Golgi apparatus
4) Lysosomes
5) Vesicles
6) Endosomes
These membranes divide the cell into functional and structural components.
<u>Peroxisomes</u> are also covered with membranes but they are not considered as the part of endomembrane system as <u>they don't recieve vesicles from Golgi apparatus.</u>
Similarly the membranes of mitochondira and the chloroplasts also are not included in the endomembrane system because their functions are not coordinated with the organelles involved in the endomembrane system.
General transcription factors, along with TAFs, recruit RNA polymerase and position it at the start of the protein-coding sequence. <span>TAF is part of the transcription initiation protein complex or the Pre-initiation complex which has a role in starting the transcription. This complex mediates transcription of DNA to RNA by RNA polymerase II.</span>
