Answer:
A good answer should contain the following:
viscoelastic
Isostatic equilibrium
asthenosphere
This theory explains how the tectonic plates in the lithosphere can move freely on the asthenosphere. The lithosphere is less dense than the asthenosphere. There's an equilibrium of the buoyancy between the lithosphere and asthenosphere.
Explanation:
Answer:
The correct answer would be D.Alveolar sacs are surrounded by thin capillaries where gases can be exchanged.
Alveoli are tiny sacs which form the site of gas exchange in the lungs.
The features of alveoli which help in gas exchange are:
- They increase the surface area in the lungs thus, more space is available for gas exchange.
- They have very thin walls, as thin as the thickness of a single cell only.
- They are surrounded by a bunch of thin capillaries which exchange gases with alveoli.
Answer:
GACCTG (the fourth option)
Explanation:
To find the correct complementary strand, we need to know this simple rule:
T always pairs with A and C always pairs with G.
So whatever letter you have in the DNA strand, the complementary strand will have the complement to it. In this case, we have CTGGAC. The complement of C is G, for T it is A, and so on. Therefore, the correct complementary strand is GACCTG (the fourth option).

Ecosystems can be large and are made of biomes. Some examples of ecosystems are deserts and forests.
