Answer:
An infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.
<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:
Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.
Explanation:
Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.
Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.
A
. Leaves were trapped between layers of sediment millions of years ago, causing the imprint
Explanation:
The only true explanation that perfectly describes the rock is that the leaves were trapped between the layers of sediment millions of years ago causing the imprint.
Leaf imprints are often referred to as trace fossils.
- Trace fossils points to the different life activities an organism must have been engaged in.
- When a leaf is trapped in a soft sediment between two layers, the compaction of the sediment can duplicate the form of leaf on beds.
- This gives a physical overview to the nature of leaf.
- Such an imprint did not grow, and cannot be attributed to metamorphic processes(option D).
- Option C is completely wrong
