Before the marble starts rolling, it is potential energy. Once it is rolling, it is kinetic energy. You know it stays the same because the marble probably would not be rolling if it weren't. All that's happening is that the ball is rolling faster because of gravity.
<span>Gravity assists the marble, leading to conservation of energy. The
stored energy is release as momentum, the output of energy is constant.</span>
I think the correct answer from the choices listed above is option A. The statement that describe the structure of each type of macromolecule would be that the <span>building blocks of carbohydrates are sugars that are made of carbon, hydrogen, and oxygen. Hope this answers the question. Have a nice day.</span>
Answer:
The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called <em>phylogenetic tree</em>
Explanation:
The phylogenetic tree is composed of,
• Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches.
• Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.
• Root → This is the older common ancestor that all lineages share. The first one in the tree.
Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
There are also different phylogenetic relationships between lineages.
• Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.
• Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.
• Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.
<span>In one sample, the potatoes that have more sugar will also have more water that will diffuse into them. Potatoes are hypertonic in relation to pure water,simply put, they will gain extra water weight as well as displace more water than potatoes that are lower in sugar. In a separate sample, potatoes that have a higher concentration of sugar will also lose far less water due to their lack of hypotonic nature. Those with lower sugar will easily loose more water.</span>
The answer is Porifera. This is supported by the evidences such as the lack of true tissue in sponges and the close similarity between choanocytes and choanoflagellates. Phylum porifera majorly comprises of sponges which are simple invertebrates animals that live in aquatic habitats. Most of the sponges are marine, however, Some species may live in freshwater lakes and streams.
