Because air pressure decreases at the rate of 0.91 inches per 1,000 feet of ascent, rising air expands and cools. The flat bottom of cumulus clouds defines the exact height at which a critical combination of temperature and air pressure causes water vapor within the rising current to condense into a visible cloud
The function of mitochondria and chloroplasts is related to energy. In what way does their function differ? Mitochondria produce energy in prokaryotic cells, while chloroplasts produce energy in eukaryotic cells. ... While the chloroplast get there food from the suns energy through the process of photosynthesis.
Answer:
The correct answer is C. paracrine signaling.
Explanation:
Intercellular signaling involves the transmission of the sending cell to the receptor cells. There are some basic chemical signals mechanisms between cells: Synaptic, Paracrine, Aotucrine, Endocrine, and by direct contact between cells.
In <u>paracrine signaling</u>, cells that are close to each other communicate by the release of chemical substances that can diffuse in the intercellular space. They produce changes in the target cells by altering their behavior or their differentiation. These are short distances communications that allow cells to coordinate their activities and function in a local area with their neighbors. These paracrine signals are very important in many aspects but especially during development, when a group of cells "tells" or "indicate" to another group of cells in their vecinity which identity to adopt.
I believe the 3 main parts that make a virus would be its Nucleic content - DNA and or RNA, A protein coat surrounding the nucleic acid called a capsid, and the tail used for injecting viral genome into the host cell.
Cytoplasm is basically a gel that holds everything in to cell in place, so i would say your answer is number 3.
