Which best describes the reliability of the information?
LuckyWell [14K]
There is no information attached but you can analyze which point make any piece of information reliable in general. The most important thing is that information was extracted from experiences that approved by scientists from defferent sphere, so that different people are sure about the same thing. As I understood, this article connected with  veterinary studies and this option looks like the most suitable : <span>It is reliable because the article is based on multiple studies done by scientists at multiple veterinary schools.</span>

How are food webs different to food chains? explain why food webs are more useful ​
miss Akunina [59]

The difference between Food Chain and Food Web is that in ecology, a food chain depicts the continuous flow of essential micronutrients from one level of the hierarchy to the next. A food web is a collection of food chains that are linked at various trophic levels. Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.

Does anyone know how to write a lab reportp
malfutka [58]

Hi

The purpose of writing a lab report mainly is to describe the results of your experiment and the learning outcome of your performed experiment as well.

Here are some important parts of a lab report:

Title Page:

It is not mandatory but it is good to add a title page for overall presentable formatting. It will include the title of your experiment, your name and also if there is a partner his name, the name of your lab as well as supervisor's name, along with the date experiment was performed.

Purpose/Introduction:

It is few paragraphs long tat explains the main objectives of your experiment. It may also include the results as well as  the hypothesis and barf conclusion of experiment.

Materials and Methodology:

This includes the protocols you followed for carrying out a certain experiment and also the main items you used to exectute the experiemnt like equipment, chemicals etc.

Data:

The numerical data you obtain from an experiment can look presentable if you write in the form of table.

Results

It is just an representation of your data in forms of sentences that and results are close to predictable findings and how reliable they look.

Analysis  or Discussion

Here you discuss your results that how they are similar or different to the experiments of similar nature that are already conducted. You can give your opinion as per your knowledge and interpret your results so that they make a sense for the reader.

Conclusions

Just conclude the report in one small paragraph that how your experiment accepted or rejected your hypothesis.

Figures or graphs:

You can include some figures and graphs that support your experiment.

References:

Here you will add the links or citations of the work that helped you in carrying out experiment or writing the lab report like journal articles, website articles etc.


Hope it help!

1. What is the force behind mass movements?
Sergeu [11.5K]
The correct options are as follows:
1.GRAVITY.
 Mass movement refers to the movement of surface materials such as soils, mud, rocks, etc down a slope. The force of gravity is responsible for pulling the materials down the slope. Mass movement usually occur along mountain side and hill side as a result of angle of repose of the land form involved.

2. MASS MOVEMENT ALWAYS LEADS TO LANDSLIDE.
This statement is not true, mass movement does not always result into landslides. Mass movement basically leads to bulk movement of earth surface materials from one location to another location. It can happen rapidly or gradually over a long period of time.

 3. THE ANGLE OF THEIR SLOPES IS GREATER THAN 40 DEGREE.
 The principal cause of mass movement is the slope angle of the land form concerned. If the angle is overly steep, that is, above 40 degrees, the force of gravity will pull the surface materials downward causing a mass movement.

4. SLUMP.
 Slump refers to the downward movement of large segments of earth surface, which occur when the base of a land form can no longer support the weight at the top of the land form. The sediments usually break off in one piece and water is usually one of the factors that lead to the break off.

 5. MUD FLOW.
 Mud flow refers to the type of mass movement that involves rapid, surging flow of materials that has been made liquefy by the addition of water. Mud flow usually contains large amount of clay, which makes it fluid in nature and enhances its ability to travel over long distances. Mud flow is usually made up of different materials which have different sizes.

6. EVAPORATED.
 Huge amount of water are usually evaporated from different water bodies on a daily basis as a result of heat from the sun. When the cloud become saturated with the evaporated water, the water is release back to the earth in form of rainfall. Thus, the amount of water evaporated from the earth surface and the amount of rainfall released to the earth are usually of equal amount.

7. VELOCITY.
 The velocity of a river refers to the speed with which the water body moves through its channels. Water velocity is usually highest near the surface and lowest near the bottom. The higher the velocity of a water body, the higher will be its ability to transport materials and the reverse is also true.

 8. GRADIENT.
<span>Gradient refers to the stream grade, which is measured based on the ratio of drop in elevation per horizontal distance. It is usually measured in meter per kilometer or feet per mile. A high gradient implies a steep slope and rapid flow of water while a low gradient translate to slowly moving water.</span>
