Answer:
It depends what kind of water.
Explanation:
Salt water:
You would need a negative buoyancy.
Fresh water:
You would need a neutral buoyancy.
Please let me know if I am wrong!
Buoyancy is the tendency of an object to float at the upper surface of the fluid due to upwards force. If the diver wants to stay below the water surface then they will need negative buoyancy.
What is buoyancy?Buoyancy has been defined by the upthrust experienced by an object in a fluid or liquid medium. It is a force that opposes or counters the weight of the object. Buoyancy can be positive, neutral, or negative. Positive buoyancy makes object float.
A negative buoyancy occurs when the object has more mass and density than the fluid so that the applied force makes them sink. So, if a person wants to stay 20 feet below the surface of the water then negative buoyancy has to take place.
Therefore, negative buoyancy will make a person stay at the bottom of the water.

True or False Water moves from an area of low water concentration to an area of high water concentration.
Answer:
False
Explanation:
It is true that water moves from an area of higher water concentration to an area of lower concentration.
Based on osmotic pressure, water always moves from an area of higher concentration to that of lower concentration.
Osmosis of water and liquids is made possible across a concentration gradient. Water is driven from one place to another via concentration gradient.Whch lists correctly orders the outer planets from least to greatest from the sun
Answer:
The order of planets from closest to farthest from the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The largest planet is Jupiter, followed by Saturn, Uranus, Neptune, Earth, Venus, Mars and, the smallest planet, Mercury.
Explanation:

What are planets?A planet is a celestial body that orbits the Sun, has enough mass to overcome rigid body forces and assumes a hydrostatic equilibrium shape, and has cleared the neighborhood around its orbit.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are the planets, in order of their distance from the Sun.
Jupiter through Neptune all have ring systems, and all except Mercury and Venus have one or more moons.

If the new growth is matter, where do you think that matter comes from? Restate this question and answer with 3-5 sentences.
Answer: The reframe question is Does new growth is caused by a matter, from where this matter comes from?
Explanation:
The growth can be defined as the increase in the physical size of a body form. The matter here are the number of cells which divide and differentiated at a faster rate. The cells developed into specialized cell types to perform specialized functions some cells are associated for growth. Thus, the matter for the growth comes from dividing and differentiated cells.

A frameshift mutation is a dangerous mutation because it
Answer:
"A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three. "Divisible by three" is important because the cell reads a gene in groups of three bases. Each group of three bases corresponds to one of 20 different amino acids used to build a protein. If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly."

Why do saturated fatty acids have straight structures, while unsaturated fatty acids have bent structures?
Answer:
Saturated fatty acids exhibit a linear structure while unsaturated fatty acids bend, or kink, due to double bonds within the chemical foundation.
Please mark for brainliest.

Based on the data, identify the shrubs and data point where the greatest flow of electrons through chloroplast electron transport chains most likely occurs.
Answer:
Thylakoid membrane and Krebs cycle.
Explanation:
Thylakoid membrane is the region in the chloroplast where electron transport chains occur while the Krebs cycle is the stage in which this electron transport chains occurs and produces large number of ATP. If the electron transport chain does not occur, very low amount of ATP is produce because electron transport chain is responsible for the production of high amount of ATP.
