When a cardboard is slowly pulled let's say for example there was a coin which is placed on the top of the cardboard and then the cardboard is pulled slowly the coin which is on top moves with it.
There is a friction force which is being applied between the coin and the cardboard which makes the coin to continue moving with the cardboard.
If it is flicked, the coin will not move will remain and cardboard will move.
The coin did not move because of its tendency to remain at inertia.
The process is called peer review. Scientists are obligated to publish their research in scientific journals. The number of publications a scientist has will impact his or her career path and advancement. When a scientist finishes a study, he/she and his/her collaborators will write a manuscript outlining and discussing the results of the study. This manuscript will be sent to a journal for publishing. There are usually several journals publishing within each field, with some more prestigious than others, as indicated by an impact factor. Journals such as Science and Nature have the highest impact factor as they have the greatest readership. The editor of the journal will send the manuscript off to other scientists working in the same field, and will ask them to 'peer review' the manuscript to determine whether the paper deserves publication, whether it requires corrections, or whether is should be rejected outright. Ideally, papers should be rejected because of bad science, and not because the results contradict previous studies or current scientific theory.
Answer:
This question is asking to formulate a hypothesis for the experiment in the question. A hypothesis is:
IF natural compost is used instead of artificial fertilizer, THEN the tomato plants will grow faster and taller than when artificial fertilizer was used.
Explanation:
In an experiment, a hypothesis is formulated to provide a possible explanation or solution to an observed problem or question. The hypothesis must be testable or falsifiable via an experimentation.
In this experiment involving a biology student who is trying to find out if using natural compost will cause his tomato plants to grow faster and taller than his previously used artificial fertilizer. A possible hypothesis for this experiment goes thus:
IF natural compost is used instead of artificial fertilizer, THEN the tomato plants will grow faster and taller than when artificial fertilizer was used.
The dam acts as a barrier between upstream and
downstream. Dams are also built for
irrigation, but it is also deliberately destroyed in favor of irrigated
farming. Though it provides freshwater, and makes people be protected by
droughts, but it can also damage the agricultural resources by limiting the
water in some areas.
<u>Answer:</u>
<em>The steps in making packaging and exporting a protein from a cell are listed below in the following points:</em>
- <em>Protein is made from the Ribosomes.</em>
- <em>These proteins are gathered in the endoplasmic reticulum. </em>
- <em>From ER the proteins are exported to the Golgi bodies. These Golgi apparatus is found in the vesicles.</em>
- <em>The Golgi bodies modify the protein to suitable forms that can be absorbed.</em>
- <em>Finally it is transported to all part of cells in our body.</em>
