Progressive age-changes in metabolism and physicochemical properties of cells, leading to impaired self-regulation, regeneration, and to structural changes and functional tissues and organs.
The heat generated in response to food ingestion is called thermogenesis (the production of thermal energy). <span>During the ingestion, the chemical energy stored in the food can be converted to thermal energy because our body produces heat when digesting our food.</span>
Answer:
Brassinosteroids are synthesized from phytosterols and they promote plant growth and development by modulating cellular processes (e.g, cell division, elongation, photomorphogenesis, responses to environmental stimuli, etc).
Explanation:
Brassinosteroids are phytohormones similar to steroid hormones. Phytosterols include sitosterol, campesterol, and stigmasterol, i.e., lipid (cholesterol) molecules that form the cell membranes. These polyhydroxylated steroidal phytohormones play a wide range of cellular roles during plant growth, development and immunity. Examples of brassinosteroid functions include plant development, xylem differentiation, responses to biotic/abiotic stresses, reproduction, etc. For example, campesterol, which is a precursor of brassinosteroid hormones, is an integral membrane component that functions during plant embryogenesis by regulating the permeability of cell membranes and by altering membrane-associated proteins, as well as signal transduction pathways.
Part A
- Yes because when it comes to whales and humans we have a lot in common. They have different behaviors and languages within their own culture as humans do.They come in a lot of sizes and have different behaviors. Just like us and they are also mammals. While other sea creatures have gills.
Part B
I hope this help's a tiny bit!
- Humpback whales are very big ocean animals, they have bumps all over their body and have a white stomach while the rest are almost black.
- Humpback whales are very similar to other whales because of their size and features.
- I do think some other existing species share an evolutionary lineage with humans or humpback whales. The blue whale as almost the same pattern and size of the Humpback whale. And share some of the same DNA.
