Archea and Bacteria have prokaryotic cells, meaning their cells do not contain a membrane enclosed nucleus or other membrane enclosed organelles. The Eukarya ribosomal RNA (rRNA) sequence is unique and different from either the Archea or the Bacteria.
Sorry if this doesn't help :/
Answer:
The main purpose Ramsar Convention is to protect and preserve the wetlands.
Explanation:
- Ramsar in a location in Iran.
- In 1971, an international treaty was signed for the protection, conservation, and use of wetlands in a sustainable manner.
- Wetlands are water filled area having diverse population of plants and animal species.
- They in rich in both the aquatic and terrestrial plant and animal species.
- In order to protect these biological hotspots the Ramsar Convention Treaty was signed.
Te answer would be <span>C. "Some mutations can be contagious, like infections.</span>" Mutations happen regularly and are often so subtle that we do not notice them on a daily basis. Some of them, however, can indeed cause harm.
Answer:
The flow chart for the cortisol steroid hormone is as follows:
1. Cortisol passes through the plasma membrane into the cytoplasm.
2. Cortisol receptor complex form in the cytoplasm.
3. Cortisol receptor complex enter the nucleus where it binds to gene.
4. Cortisol receptor complex acts as transcription factor.
5. The tranacribed mRNA is translated into specific protein.
Explanation:
Cortisol is small which is hydrophobic steroid hormone which has the ability to move through the plasma membrane of the cells. In the target cells the cortisol binds with the intracellular receptor protein of the cytoplasm which further forms a hormone receptor complex. The hormone receptor complex further moves into the nucleus ad hence acts as a transcription factor which gets bind to the specific gene and thus, activates the transcription into mRNA. The mRNA which is generated subsequently translated into some specific proteins. Proteins which has been produced with response to the cortisol signal function to the stress response.
The answer is cross-pollination.
