Answer:
A. COAGULATION
Explanation:
Hemostasis is stopping bleeding. To prevent or keep blood in the blood vessels due to damage of the vessels.
Three steps are important in hemostasis;
1. Vasoconstriction : which is the contraction of the smooth muscles of the blood vessels reducing the amount of blood flow to the area of damage and thereby blood loss.
2. Platelet Plug Formation: this is the function of platelet in the blood. It attaches to the damaged endothelium and form a plug.
3. Coagulation/ Clotting : this is the release of clotting factors to the surface of the damaged vessel.
Fibrin is a major component of the clotting factor.
So therefore, coagulation is a process in hemostasis. Formation of platelet plug is a stage also and not the formation of platelet in the blood.
It is rare for soft tissue to become a fossil because the soft parts can be eaten by other animals. Hope this helps!
What you need to do is take one of the 3 Investigation samples and list it next to "My topic."
Then you need to find a source for your selected topic and follow the list in the first note card.
Usually the more information a source has about the author, and the publication, makes it more reliable.
Once you have that down, you need to provide the 2-3 sentences explaining why you think your selected source is valid and reliable enough to be used in a scientific research paper. You might google sources used in scientific research papers to get an idea.
If you can find sources with authors that have well known names or people who know a lot over your specific topic, then its more trustworthy.
For the next note card, do the same thing, but find another source. All your note cards will be over your one selected investigation sample.
So for instance, if you selected Electromagnet, then each note card will have different sources that mention anything having to do with your topic Electromagnet.
Hope this helps :)
Answer:
wow false that is all i can give u
Explanation:
Answer:
A. gas molecules having three or more atoms
Explanation:
A greenhouse gas has the property to absorb infrared radiation and radiating it back to the earth surface.
A greenhouse gas must have three atoms or more, that will help the gas to absorb infrared radiation and restricts its way out of the atmosphere. some example of greenhouse gases are methane (CH4), carbon-dioxide (CO2) and nitrogen oxide (NO2).
Hence, the correct answer is "A".
