The correct answer is: Events that occur early in the fossil record are represented by branching events nearer to the root of a phylogenetic tree.

Fossil records explain the history and evolution of life based on fossils. Fossils are remains of organisms preserved in sedimentary rock. In fossil records they are analyzed and arranged chronologically and in taxonomic order, so that can represent the evolution.

Phylogenies describes the relationships between organisms (species): from which organisms it is evolved, to which species it is most closely related etc. and it is represented as a diagram or phylogenetic tree. It is used to organize living organisms into specific categories. Characteristics of fossils are used to generate a phylogenetic tree, more precisely their roots that represent common ancestors.

Answer: Increased concentration of glucose in leaf cells

Explanation:

Based off the flowchart, the process that it's describing is photosynthesis because during this process sunlight and CO2 are taken in by a plant to produce glucose. If we are exposed to sunlight and are increasing the use of CO2, then there must be a higher concentration of glucose in the leaf cells. Glucose is a product of photosynthesis.

Brut [27]

Answer:

Q: Which skeletal system disorder might she be suffering from?

A: Osteoporosis

Q: What techniques could be used to diagnose her condition?

A: Bone mineral density (BMD) test or dual energy X-ray absorptiometry (DXA) scan

Q: What treatments are available?

A: Medication, healthy food.

Explanation:

The vertebral discs between vertebrae could shrink with age. Therefore, a height loss up to 1-inch is normal. However, if the height loss is more then it is possibly due to osteoporosis.

A bone mineral density test, also known as dual energy X-ray absorptiometry scan, is a well-adapted test to measure the amount of calcium and other minerals in the bones. It uses X-rays to measure the content of calcium and thus strength of bones.

A person who is already suffering from osteoporosis should be treated with medicine right away so that it stops further deterioration of the bones and avoid any future bone fractures. Further, it can be handled by eating a healthy diet and supplements such as vitamins D. In case some of the bones/vertebrae are already fractured, surgical approaches might be necessary.
