If these are your choices:
A. Warm water increases the speed of sound.
B. Cold water increases the speed of sound.
C. High water pressure decreases the speed of sound.
D. Low water pressure increases the speed of sound.
The answer is B. because warmer particles rises which is less dense than the cooler particles. Sound waves travels faster in a denser medium making statement B as the correct answer.
Another pair of organisms are in the same genus
<span>1. List the adaptation that ALL vertebrates have in common.
The vertebrate is a subphylum of kingdom Animalia. The member of subphylum should have a spine or vertebrae. Therefore, all vertebrates should have vertebrae. All the member should have all the classification above the subphylum like cranium from craniate and notochord from chordate.
2. List all the adaptations that your chordate has (as shown on the cladogram).
The frog is part of Amphibian that shown on green lines. It should have all the organ above its classification such as jaws and paired appendages, lungs(frog can live in the land), four limbs. It also has all the trait of vertebrates that was described above.
3. To which type of chordate is your chordate most closely related?
If your chosen chordates are the frog, then salamander and caecilian would be the most closely related chordates. The reason is that salamanders and caecilians are also amphibians like the frog, which means they have all the trait from amphibians.
4. Why do you think endothermy appears at two points on the cladogram?
Endothermy member is the chordates that have warm blood. There are two chordates that have warm blood in the cladogram, the apes(mammals) and the bird. Since the bird is classified as reptile the but the ape classified as mammals, the cladogram needs to put two </span>endothermy.<span>
5. Amniotic eggs have a waterproof membrane. What type of animals evolved from animals that lay amniotic eggs?
</span>The amniotic eggs will be found on the reptile. The eggs have a waterproof membrane to prevent water comes out of the egg. Water is an important resource and if a high amount of water leak from the egg, the egg will be dried out and die. <span>
6. In what type of habitat do you think the evolution of amniotic eggs helped animals survive? Hint: In what habitat do all animals without amniotic eggs live?
The amniotic eggs help an animal that lives on the dry land to make offspring. All of the animals before reptiles are living in the water and spawn their eggs there so there is no concern about losing water, thus waterproof membrane is not needed. Reptile spawns their eggs on land, so it needs a method to contain the water.</span>
Answer:" AI'll practice these now and try to start them as soon as I can after my surgery."
Explanation:
→Leg exercise should commence immediately after surgery to avoid blood clot..
→Blood circulation to the legs can be aided by pumping the ankle or drawing a circle with the ankle
→Range of motion practise should be intensified;the injured parts should be flex slowly, and toes should be used to draw alphabets, with each leg lifted individually, not in prone position.
→Hip abduction should be carried out, so that the body is away moved from the center of the body
