Answer:
About 61% / over 60%
Explanation:
In 2021, about 4,116 billion kilowatthours (kWh) (or about 4.12 trillion kWh) of electricity were generated at utility-scale electricity generation facilities in the United States.1 About 61% of this electricity generation was from fossil fuels—coal, natural gas, petroleum, and other gases.
Answer: The cellular process that enables the cells to grow and develop into tissue is called MITOSIS.
Explanation:
The skin is the largest organ of the body that contains various cells which includes: the epidermal and dermal cells. With the various activities of man, the skin is susceptible to injury through burns.
The healing of the skin, especially injury sustained from burns involves the interaction between the different cell types. Recently, scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries which are grown from living cells.
MITOSIS is the cellular process that enables the cells to grow and develop into tissue. It is also defined as the process by which a cell duplicates into two genetically identical daughter cells.
The process of mitosis occurs in 4 stages; the prophase, metaphase, anaphase, and telophase. The various activities that occurs on these stages brings about the growth and the development of the cells into tissue.
Eukaryotic cells have been confronted throughout their evolution with potentially lethal plasma membrane injuries, including those caused by osmotic stress, by infection from bacterial toxins and parasites, and by mechanical and ischemic stress. The wounded cell can survive if a rapid repair response is mounted that restores boundary integrity. Calcium has been identified as the key trigger to activate an effective membrane repair response that utilizes exocytosis and endocytosis to repair a membrane tear, or remove a membrane pore. We here review what is known about the cellular and molecular mechanisms of membrane repair, with particular emphasis on the relevance of repair as it relates to disease pathologies. Collective evidence reveals membrane repair employs primitive yet robust molecular machinery, such as vesicle fusion and contractile rings, processes evolutionarily honed for simplicity and success. Yet to be fully understood is whether core membrane repair machinery exists in all cells, or whether evolutionary adaptation has resulted in multiple compensatory repair pathways that specialize in different tissues and cells within our body.
desert, open ocean, lake, tropical rain forest
Explanation:
The net primary productivity tells us about how productive an ecosystem is. It is usually derived by the difference between the amount of carbon dioxide that producers used to the amount they release during their cellular respiration.
- The rainforest is the biome with the highest amount of net productivity.
- The amount of sunlight and organic matter used up during photosynthesis is very large.
- The tropical rain forest receives the highest amount of sunlight because the sun is overhead here.
- This provides energy to drive photosynthetic process in the presence of other available resources.
- Deserts are bare and lacks plants due to the extreme conditions here not favorable to life.
- The open ocean productivity is restricted to the photic zone where light is only able to reach
- Lakes are highly productive ecosystems.
