Explanation:
Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases.
hope this helps!!
<span>The Antarctic Circle has 24 hours of daylight around the summer solstice. In the southern hemisphere this would be around December 21.
When energy is transferred to air the particles of air move faster. Adding energy to molecules makes them move faster and air is no exception.</span>
Answer:
The correct answer is - mitochondria lack ribosomes like prokaryotes.
Explanation:
The Endosymbiotic Theory says that mitochondria and chloroplast in eukaryotic cells are developed by the once aerobic bacteria that were engulfed by a large anaerobic bacteria.
This theory suggests the origin of eukaryotic cells. Various evidence exists such as mitochondria and chloroplasts contain their own circular DNA like prokaryotic cells and mitochondria and chloroplasts have 70S ribosomes like prokaryotes have.
Secondary active transport protein link the transport of an ion downward its gradient with the transport of another particle against its gradient, whereas primary active carrier proteins move both components in the opposite direction of their respective gradients.
<h3>Which proteins are essential for active transport?</h3>
Instead of channel proteins, carrier proteins are used in active transport. Since these carrier proteins require ATP to change shape, they differ from those seen in facilitated diffusion.
<h3>Why do proteins play a part in active transport?</h3>
- Specialized carrier proteins are needed for active transport, and cellular energy must be used.
- When a chemical's phospholipid bilayer is impermeable to it or when there is a concentration gradient, carrier proteins allow chemicals to pass through the membrane.
<h3>What kinds of proteins are carriers?</h3>
The carrier proteins can be categorized as being driven by ATP, electrochemical potential, or light, depending on the source of energy.
