What type of pressure means the air around you is densely packed?.
In the atmosphere, the density of air debris decreases with height, with greater fuel online debris the last close to the floor of Earth. When simplest thinking of humidity, dry air is greater dense than wet air due to the molecular weights of the gases.
Solids have a tendency now no longer to transport very much - they have an exact form and normally live wherein they are put. Liquids and gases then again are lots greater willing to transport - they are fluid. That's why fluid is both a liquid and gas.
What is atmospheric pressure?It is described as the pressure in the atmosphere also called barometric pressure, within the earth's atmosphere.
Hence concludes that the air around you is densely packed due to the fact that The accurate announcement is denser exerts extra strain than much less dense air. Explanation: that is due to the fact with the boom in the density there are extra molecules of air that can be packed inside a selected extent of air.

Explain why scientirsts concluded that the instructions for species characteristics were carried in DNA.
Answer:
Explanation:
Deoxyribonucleic acid is said to contain instruction for species characteristics because it carries the information that characterize an individual.
DNA are made up of Nitrogenous bases that are unique codes specify by an individual and no two person has the same the DNA.
Genes are genetic information or instruction that specify an individual. it is located in the chromosome in the nucleus. DNA contains gene which helps to make molecules called proteins. It is the basis of all inheritance and the expression of the gene is what produces the phenotype that is visible.

Hormones are controlled by a feedback loop; information about a system is sent back to the controller of the system to improve its function.
Hormones are controlled by oxygen levels; the internal environment maintains all systems, including endocrine functions.
Hormones are controlled by muscles; hormones are released when muscles contract and stopped when muscles relax.
Hormones are controlled by the nervous system; the spinal cord sends messages about hormone levels to the brain.

Which two factors will increase the rate of a stream’s flow?
Answer:
Flood Erosion and Deposition: As flood waters rise, the slope of the stream as it flows to its base level (e.g., the ocean or a lake) increases. Also, as stream depth increases, the hydraulic radius increases thereby making the stream more free flowing. Both of these factors lead to an increase in stream velocity.
Explanation:
Flood erosion and deposition, as flood waters rise, the stream's slope rises as it descends to its base level, which may be an ocean or a lake.
What is the stream’s flow?Additionally, when stream depth rises, the hydraulic radius rises as well, increasing the stream's ability to flow freely, these two elements cause the stream velocity to rise.
The volume of water flowing into a stream channel from the watershed directly affects the stream's flow. The weather has an impact on it; it rises during downpours and falls during dry spells.
The force of gravity, which pushes water downhill, is what gives moving river water its energy. A river will flow more quickly and with greater energy at a higher slope.
Therefore, flood erosion and deposition factors will increase the rate of a stream’s flow.

What materials do motor neurons need to survive and how do they get those materials?
Answer:
Neurons are made up of three major parts: a cell body, or soma The part of the neuron that contains the nucleus of the cell and that keeps the cell alive., which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.
A car turns left while maintaining a speed of 20 m/s. Does the car’s velocity change? Explain your reasoning!
Answer:
Yes
Explanation:
Speed is a scalar quantity (only has a magnitude). It signifies the rate of change of an object's movement.
Velocity is a vector quantity that signifies the rate of change of movement but also the direction of an object's movement.
Since the car turns, its direction changes, so the velocity changes.
Х Flag A lake borders a housing subdivision and a golf course. Over time, algae in the lake begin to grow uncontrollably. Which is the most likely cause of the algal bloom? A runoff of topsoil from construction on the golf course B runoff of nitrates from fertilizers applied to the golf course runoff of gasoline from roads through the golf course D runoff of animal waste from pets walked on the golf course
Answer:
B. runoff of nitrates from fertilizers applied to the golf course
Explanation:
Algal bloom is defined as the rapid growth of algae in freshwater or marine water. Algal bloom is green or yellowish in color that cover the top layer of water systems.
Algal bloom in the given case is caused by the excess of nutrients that is nitrates from fertilizers into waters and higher concentrations of nitrates causes uncontrollable growth of algae.
Algal blooms are harmful for environment as they may produce toxins and can block the sunlight from reaching the plants and animals in the water systems.
Hence, the correct answer is "B. runoff of nitrates from fertilizers applied to the golf course".
