You can tell the age of a yeast cell by (a) counting scars.
Yeast is a unicellular eukaryotic organism. It belongs to the kingdom Fungi. It is primarily used in baking, cooking and in alcohol industries as well. There are various strains of yeast and the most widely used one is <em>Saccharomyces cerevisiae</em>, also called the baker's or the brewer's yeast.
Scars on the yeast are actually the bud scars formed due to budding. Budding is the process by which the yeast reproduces and gives rise to its offspring. Hence every time a daughter bud pinches off from the yeast cell, a scar is formed.

Answer:
D. Mass extinction events separate the three eras from each other
Explanation:
The Phanerozoic represents an eon, and it is the most recent one. It is further divided into three eras, Paleozoic, Mesozoic, and Cenozoic. The division between the tree eras is because of mass extinction events. The Paleozoic and Mesozoic era are divided by the Permian-Triassic mass extinctions. The Mesozoic and Cenozoic are divided by the Cretaceous-Paleogene extinction. The Cenozoic era is still in existence, as there hasn't been a mass extinction of a magnitude big enough so far.

This question is incomplete. Here´s the complete question.
A 70-year-old client with a diagnosis of left-sided stroke is admitted to the facility. To prevent the development of disuse osteoporosis, which objective is most appropriate?
a) Promoting range-of-motion (ROM) exercises
b) Promoting weight-bearing exercises
c) Maintaining protein levels
d) Maintaining vitamin levels
Answer: b) Promoting weight-bearing exercises
Explanation:
The bone is a living tissue that becomes stronger with exercise. Weightlessness and immobility can lead to bone loss.
Weight-bearing exercises are those that force us to work with gravity, like walking, hiking, jogging, climbing stairs, playing tennis, and dancing. They can help prevent disuse osteoporosis.
On the other hand, swimming and bicycling would be examples of non-weight-bearing exercises.
