All of the answers presented above are correct.
Before Gregor Mendel's research, it was believed that parents' characteristics were passed down to the next generation were not inherited as separate units, but blended together in the next generation.
While he was studying the inheritance of different traits of the pea plant such as the height of the plant, the shape and color of the seed and the variability of the color of the flowers.
During his experiments, he noticed that the simple traits as height were passed down to the filial generation separately, so they were not blending in the next generation as it was previously thought.
He managed to get purebred plants for certain traits by self-pollination of the pea plants and used them for this experiments.
He determined that some of the traits were expressed more often and with a higher ratio and called them dominant, as opposed to recessive traits that were expressed less often when cross-breeding with an individual with a dominant trait.
Answer:
This hierarchy comprises eons, eras, periods, epochs, and ages from the largest to the smallest
Explanation:
This hierarchy comprises eons, eras, periods, epochs, and ages from the largest to the smallest. All of these are shown in the geological time scale page.
Eon Era Period Epoch Age
Phanerozoic Cenozoic Paleogene Oligocene Chattian Rupelian
The Phanerozoic Eon reflects the period that most macroscopic species — bacteria, fungi, plants, and animals — lived through.
Answer: Delirium
A person who suffers delirium experience lack of
awareness of oneself or one’s surroundings. Delirium is a serious disturbance
in mental abilities results in confused thinking and reduced environmental awareness.
This manifestation is transient and usually reversible but it can occur at any
age especially in elderly who have previously compromised mental status.
BioSafety Level (BSL) 3 labs,
perform work with indigenous or exotic agents that may cause serious or
potentially lethal diseases through the inhalation exposure. Biological Safety
Levels (BSL) are a sets of protections assigned to the activities that occur in
specific biological laboratories. BSL protects laboratory workers, the
surrounding environment and also the community.
Answer:
C
Explanation:
The exerpt states that movements in the Earth's crust (unbalance) causes Earthquakes. When it's balanced, there is no plate movement.
