Answer:

Delta

Explanation:

Delta is a land-form that is formed when areas of sediment deposit at the mouth of the river. It happens when fast-moving water enters a slow-moving body such as sea, lake or ocean. There occurs a sudden decrease in stream velocity which results in the deposition of sediment load.

Deltas usually look triangular in shape as the term comes from Greek’s fourth alphabet Δ.

An increase in the permeability of the cells of the collecting tubule to water is due to a(n) ________.
OLga [1]
An increase in the permeability of the cells of the collecting tubule to water is due to an increase in production of ADH. Hormone ADH also called vasopressin is responsible for regulating the amount of water in the blood and is released from the pituitary gland based on signals from the hypothalamus, which detects the water levels of the blood. When too much water is in the blood, the hormone release is decreased and more water is excreted in the kidneys and thus increasing urine output.

Answer:

Coal.

Explanation:

Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.

What major organelle are prokaryotes missing that eukaryotes have?
djyliett [7]

Answer:

Nucleus

Explanation:

Prokaryotes are the organism that came earlier than eukaryotes on this earth. These prokaryotes do not have a nucleus and other membrane-bound organelles like chloroplast, mitochondria, Golgi apparatus, endoplasmic reticulum, etc.  

So as prokaryotes lack membrane-bound organelle their genetic material is not enclosed in the nucleus therefore their genetic material remains in the cytoplasm of the cell while eukaryotes have membrane-bound nucleus in which their genetic material are present.  

So the nucleus is the major organelle that prokaryotes are missing that eukaryotes have.
