I
Explanation:
Phosphorus, organic nitrogen and some metals ( iron or aluminium) usually attached to sediment and are carried by runoff to wet land. By holding water, a wetland allows sediment and large particles ti settle on the wetland bottom. The root systems of wetland plants then absorb nutrients from the sediment.
Neurological and perceptual speeds are generally higher in individuals with _________ intelligence.
A. general
B. lower
C. higher
D. inherited
Answer: C. higher
Neurological and perceptual speeds are generally higher in individuals with higher intelligence.
Neurological and perceptual speeds are generally found to be higher in individuals with higher intelligence. Thus, the correct option will be C.
What is Neurological and perceptual speed?Neurological speed can be defined as the speed or how fast the neurons react in the body, how fast a person acquires and processes the information. Neurological speed can be calculated through aptitude tests. These are the tests which are designed to predict a person's future performance and aptitude is the capacity of a person to learn.
Perceptual speed is the speed which indicates the automaticity as well as the efficiency of processing novel visual information and speed of decision-making of a person. Perceptual speed is typically assessed with the speeded tests that require the quick identification of specific targets from a set of stimuli in the body.
Neurological and perceptual speeds are generally higher in the individuals with higher intelligence.
Therefore, the correct option will be C.

Explain the differences between the three ways of heat transfer, conduction, convection, and radiation.
Answer:
The differences between these three ways of heat transfer are that conduction is the transfer of thermal energy through direct contact, convention is the transfer of thermal energy through the movement of liquid or gas, and radiation is the transfer of thermal energy through thermal emission. As you can see, each way of heat transfer has a different way of moving through objects.

Hi, so i was wondering How long does Mars have to travel around Earth to make it's complete rotation?
Answer:
24 hours and 37 minutes
Explanation:
At Mars' orbital speed of 24 km per second, it takes the planet 24 hours and 37 minutes to complete one rotation. That is just a little more than a day on Earth.
Answer:
The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.
4. You are running a race and you speed up from 3 m/s to 5 m/s in 4 seconds.
a. What is your change in speed?
b. What is your acceleration?
The initial speed is 3 m/s and final speed is 5 m/s. Change in speed is 2 m/s.
What is speed?The initial speed is 3 m/s and final seed is 5 m/s. The change in speed is final speed minus initial speed.
The rate at which distance changes over time is known as average speed. The pace at which displacement changes over time is known as average velocity.
Change in speed= 5 m/s − 3 m/s
= 2 m/s.
Velocity = speed/ time
= 2/ 4
= 0.5 m/s
acceleration = velocity/ time
= 0.5/ 4
= 0.125 m/s2
Therefore, The initial speed is 3 m/s and final speed is 5 m/s. Change in speed is 2 m/s.

Which process is part of the carbon cycle?
A. Photosynthesis
B. Transpiration
C. Evaporation
D. Fixation
Hey there!
Photosynthesis is part of the carbon cycle.
Plants absorb carbon dioxide & sunlight in the middle of the photosynthesis process and create glucose (a type of sugar).
I hope this helps,
have a wonderful day. :)
Photosynthesis is part of the carbon cycle. Therefore option A is correct.
Photosynthesis is a vital process in the carbon cycle, which is the biogeochemical cycle that describes how carbon is exchanged and recycled between the atmosphere, living organisms, oceans, and the Earth's crust.
During photosynthesis, green plants, algae, and some bacteria convert carbon dioxide (CO2) from the atmosphere into organic compounds, such as glucose, using sunlight as an energy source.
This process removes CO2 from the atmosphere, reducing greenhouse gas levels and helping to regulate the Earth's climate.
It is an essential step in maintaining the balance of carbon in the biosphere and plays a significant role in sustaining life on our planet.
Therefore option A Photosynthesis is correct.

B + 6 H2O + energy
What molecules does letter B represent in the reaction above?
02
O CO2
ОАТР
O H2O
The reaction of cellular respiration involves the use of the glucose molecule in presence of oxygen to produce energy and carbon dioxide. Thus, option B is correct, as molecule B is carbon dioxide.
What is cellular respiration?Cellular respiration is a chemical method that involves the inhaled oxygen and use of the food molecules to release energy along with the water and carbon dioxide molecules.
Cellular respiration can be depicted by the reaction:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
Therefore, molecule B is carbon dioxide.
