Answer:
Forms of fossil records can inlude the carcasses of animals and the structure of plants. These records can compare the advancements of creatures over a long period of time.
Explanation:
The further an animal or plant is burried underneath the soil, it is most likely that it lived much longer ago than a layer above it. The theory of evolution suggests that animals are always changing and adapting to their surroundings. For instance, millions of years ago, a dog like mamal existed but over time they grew accustomed to the water, developing fins flippers and eventually developed features similar to what we expect in whales today.
Plants, on the other hand, may have been much larger than the size they are today due to the excess of oxygen present in the atmosphere. Therefore, when they are fossilized scientists can realize that plants have come a long way in the tree of evolution.
Answer:
The statement that best represents a function of lipids within an organism is that they are components of cell membranes.
Explanation:
Lipids are biomolecules formed by the binding of fatty acids, important for structure, compound synthesis and energy reserve.
In living beings, one of the most important functions of lipids is to be the main component of cell membranes.
Specifically, phospholipids associate to form a double layer, called lipid bilayer, capable of acting as a semi-permeable membrane, due to its non-polar or hydrophobic character. In this way, <u>membrane lipids fulfill a structural and protective function of the cell and its contents</u>.
Regarding the other options:
- <em>Proteins are made up of amino acids, not lipids.
</em>
- <em>Lipids are not constituents of the DNA structure.</em>
Answer:
cardiac, smooth, and skeletal.
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
