Name the type of connective tissue that anchors the ribs onto the sternum.
Kazeer [188]

Hyaline cartilage makes up the costal cartilage that holds the ribs to the sternum. The most prevalent form of cartilage in the body is hyaline cartilage.

<h3>What is hyaline cartilage?</h3>

On the articulating surfaces of bones, in the larynx, trachea, and bronchi, as well as on the sternal ends of the ribs, hyaline cartilage is present. It imparts a rigid yet malleable form to the constructions.

Hyaline structures are connective tissues that anchor the ribs onto the sternum. Such structures and joints are robust because collagen fibers are present, but their mobility and flexibility are constrained. To reduce friction and provide cushioning at the joint surface, articular cartilage, also known as hyaline cartilage, covers the ends of bones.

What kinds of traits do not evolve through natural selection?
Harrizon [31]

Natural selection doesn't favor traits that are somehow inherently superior. Instead, it favors traits that are beneficial (that is, help an organism survive and reproduce more effectively than its peers) in a specific environment. Traits that are helpful in one environment might actually be harmful in another.

(one again, I hope this helps ^^)

In 3–5 sentences, compare and contrast the flow of matter and energy in each trophic level for land-based ecosystems and marine
Mnenie [13.5K]

Answer:

Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.

Explanation:

Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.

Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.

Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
