Answer:
Force = 15.4N
Explanation:
Force=Mass x Acceleration
Force = 20Kg x Acceleration
20Kg x 0.77m/s = 15.4N
<em>Answer is entirely dependent on what the acceleration is.</em>
1. Natural selection is the best of the organisms to live past hardships and survive, leaving the weakest to die. Survival of the fittest.
2. Adaptation is an organism changing to better themselves in a certain environment.
3. These moths were adapted to blend into their surroundings, so as to not be seen by predators.
4. Because of the pollution from the city, the tree’s bark turned from a lighter shade brown to a darker shade brown.
5. A majority of the moths were a lighter gray. With the changing color bark they were seen more by predators.
6. Adaption caused the first darker moths to appear because they learned they needed to blend into the new tree bark color.
7. The change from light to dark gray was very needed for moths. It explains natural selection for those moths who did not adapt to different color gray. Adapting the new tree bark color helped moths been less seen by predators therefor keeping their species more alive.
Answer:
The correct answer is - Basophils
Explanation:
Basophils are one of the granulocytes of WBC. The basophils move to site of damaged tissue. They cross the capillary endothelium and gathred in the damaged tissues. They discharge their granules into the interstitial fluids.
The granules which is secreted by basophils includes histamine, heparin, and serotonin.The histamine dilates blood vessels, the heparin prevents blood clotting.
These chemicals into the interstitial fluids enhances the inflammation initiated by mast cells.
Answer:
Let's pick six liquids randomly, i.e. honey, corn syrup, whole milk, water, vegetable oil, rubbing alcohol, and put them in a beaker. The higher density liquid will take the bottom position whereas lower density liquids will be on above of high density liquids.
We know that honey has density (g/cm3) of 1.42, dish soap has 1.06, corn syrup has 1.33, milk has 1.03, water has 1.00 (standard), and vegetable oil and 0.92. Therefore, honey will be at the bottom most position (rank #1). Above which would be corn syrup (rank #2), dish soap (rank #3), milk (rank #4), water (rank #5) and vegetable oil (rank #6).
The results might be surprising for some students who think that water has highest density.
