6. Explain the relationship between high and low permeability and porosity.

7. What is the relationship between an observation and an analysis in an experiment or study.

Answers

Answer 1

Answer:

Question 1. Polarity. A water molecule is slightly charged on both ends. ...

Cohesion. Hydrogen bonds hold water molecules together, as seen in the picture above. ...

Adhesion. And

High Specific Heat. Question 2. The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. ... The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.Question 3. Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy. Question 4. Hurricanes often bring with them a storm surge, which is a broad dome of higher sea level, lifted up by the low pressure in the storm center. ... So, in summary, tsunamis are caused by earthquakes shifting the ocean floor, and hurricanes are big storms that form in the atmosphere over warm ocean waters Question 5 - . Water is generally classified into two groups: surface water and groundwater. In general: Groundwater is located underground in large aquifers and must be pumped out of the ground after drilling a deep well. Surface water is found in lakes, rivers and streams and is drawn into the public water supply by an intake. Question 6: If the material has high permeability than pore spaces are connected to one another allowing water to flow from one to another, however, if there is low permeability then the pore spaces are isolated and water is trapped within them. Question 7 : What's the difference between observational and experimental studies? ... a observational study is where nothing changes and just record what you see, but an experimental study is where you have a control group and a testable group.

Two guard cells make up the stomata. The walls of these cells are thicker on the inside than they are on the outside. Stomata open when they take in water and close when they lose water due to the unequal thickness of the paired guard cells.When stomata open, they release water vapor and other gases into the atmosphere, including oxygen.A.

What role have nitrates and phosphates played in damaging Muddy Creek?

Answers

Answer:

Nitrates and phosphates lead to eutrophication and anoxia in the creek which caused aquatic animals to die and damaged the creek.

Explanation:

Nitrates (NO3-) are chemical compounds that contain nitrogen and oxygen molecules. They are salts that are commonly found in fertilizers and are soluble in water. Phosphates are also compounds that are used in agricultural processes.

Nitrates and phosphate found in water are usually from plants that  have been washed off by rain water and also from vehicles' exhaust.

When there are abnormally high levels of nitrates and phosphates in water, it becomes difficult for aquatic animals to survive. In bodies of water, the nitrates and phosphates become sources of food to algae and other plants, this causes them to become over stimulated, and lead to Eutrophication (a high concentration of nutrients) and Anoxia (lack of oxygen).

This causes the fishes to run out of oxygen and die. Then the water begins to change color (milky white or green), give off an offensive odor and gradually turns into a  swamp and eventually a meadow

The scenario which describes a relationship of parasitism is a tick feeds on the blood of a dog. Therefore, the correct option is D.

What is parasitism?

In parasitism, one organism (the parasite) benefits at the expense of another organism (the host). In this scenario, the tick benefits by feeding on the dog's blood, while the dog is harmed by the loss of blood and potential transmission of diseases by the tick.

Option A describes a mutualistic relationship, where the ox pecker birds benefit by feeding on the ticks, and the zebras benefit from having the ticks removed.

Option B describes a predator-prey relationship, where the polar bear benefits by catching and eating the seal, while the seal is harmed by being eaten. Option C and D describe commensalism. They both are same. Therefore, the correct option is D.

If purple flowers are dominant in a plant and white flowers are recessive in that plant, then when purple-flowered

B

с

D
100% purple flowers

Answers

im pretty sure it would be c

If purple-flowered  plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first  generation of offspring should have 100% purple flowers.

Genes are defined as units of inheritance that occur in the chromosomes. Usually, genes occur in pairs called alleles and these alleles control the expressed traits (phenotype) of an organism.

In this case, we have a flowering plant having a dominant gene for purple flowers (R) and a recessive gene for white flowers (r). Using a punnet square, we can see that the first generation will have all purple flowers since it is the dominant gene as shown.

Answers

This answer is TRUE !! Hope this helps you out a little :)

Ocean salinity varies from place to place due to differing conditions in the environment is a true statement.

How ocean salinity varies?

It is not evenly distributed, but it does change temporarily and spatially with the oceans and seas.

This variation is both horizontally and vertically distributed; horizontal distribution refers to salinity changes at the ocean's surface level and vertical distribution, to salinity changes as the ocean's depth.

Several variables influence ocean salinity. They are global warming, evaporation, rainfall, river water input, ocean currents, atmospheric pressure, and wind direction. Oceans and seas have a 35 average salinity.

Therefore, It is not evenly distributed, although it does change momentarily and spatially with the oceans and seas.
