Answer:
The correct answer is - a. The Porifera are asymmetrical, while the Cnidaria are radially symmetrical.
Explanation:
In biology, symmetry f the body is meant the presence of a pair of organs in an orderly manner that if divide the body each part is a mirror of the other. In the phylum Porifera have asymmetric body plane.
Some animals develop into adults with radial symmetry. Cnidaria adults have radial symmetry type of body plans that eans if they are cut from the middle they divide in the two equal organs into both sides.
Environmental conservation protects wildlife and promotes biodiversity. Maintaining a healthy and functional ecosystem helps prevent the extinction of certain animal species. If the environment is destroyed, some animals are forced out of their habitat, making it hard for them to survive elsewhere.
Answer:
Collagen fibers provides high tensile strength.
Explanation:
The extracellular matrix of connective tissue has three types of fibers: collagen, elastin and reticular fibers. Collagen fibers are sometimes called white fibers and are strong and resist stretching. These fibers are present in parallel bundles which in turn impart great tensile strength to the connective tissue.
Elastin fibers make a fibrous network in the matrix. Elastin fibers can be stretched up to 1.5 times their original length without breaking and resume the original shape after stretching. This ability of elastin fibers impart elasticity to the connective tissue. Reticular fibers also form the branched network in the extracellular matrix of the connective tissue.
The central element for all living things is carbon, which is why you might often hear the phrase "carbon-based" lifeforms. Another term is often "organic matter"
The answer to this is C because when the sun shines on the water it tends to heat up because water is like a mirror it reflects the light of it but in doing so it is heating up the water making the water really hot.
