Answer:
Scientists learn how climatic changes during the ice age affected life in this region by analyzing specimens found in these tar pits
Explanation:
La Brea Tar Pits are a group of tar pits in Los Angeles. Many preserved remains of ancient organisms (i.e., fossils) were extracted from the tar, including, among others, Western horses, prehistoric camels, three-toed tapirs, rodent bones, insects, mollusks, wood, plants, etc. The oldest fossils have been dated to be approximately 38,000 years ago by radiometric techniques. Moreover, the Last Glacial Period was the most recent glacial period within the Quaternary glaciation, which encompassed the period between 115,000 to 10,000 years ago. This period (LGP) encompassed the Last Glacial Maximum (LGM), which occurred about 20,000 years ago. In consequence, many of the fossils found in La Brea Tar Pits evidence how the ice age affected life in this region. Moreover, many of the fossil species extracted from the tar are still present today, thereby indicating how these species adapted to fluctuating climatic conditions, whereas certain species couldn't adapt fast enough as the environment changed and therefore they went extinct.
A complementary process in nature either adds (options 3, 6, and 7) or removes ( options 4 and 5) carbon dioxide from the atmosphere.
<h3>Complementary processes and it's benefits</h3>
The processes that leads to the addition of carbondioxide back to the atmosphere include the following:
- The eruption of volcanoes.
- Cellular respiration carried out by organisms to release energy from food molecules.
- The use of gasoline to power cars
The processes that leads to the removal of carbondioxide from the atmosphere include:
- The production of energy-rich carbon compounds through photosynthesis.
- The dissolution of carbondioxide in rainwater.

Answer: A. Extirpation
Explanation:
The term extirpation is also known as local extinction. It is situation whereby a particular species ceased to exist in an environment where it was once found, though it's existence is still observed elsewhere.
Extirpation maybe as a result of unfavorable environmental and human factors such as hunting, food scarcity and climate variation.

Answer and Explanation:
The cell division cycle is responsible for increasing and maintaining cell number and size. This cycle is an essential feature of living organisms. There are four phases of cell division mitotic phase (M phase), growth phase 1 (G1), growth phase 2 (G2), and synthesis phase (S). One phase of the cell cycle ends, and the other starts; this is named a phase transition—a unidirectional alteration in the cell cycle phases. During G1, G2, and S phase cell grows and during the M phase cell divides. There are two models of cell reproduction as the clock model and the domino model. The domino model implies that cell division phases must occur in a distinct order and at a definite time. The domino model recommends that the cell cycle events are independent, while the clock model shows that the effectiveness of mitosis entrance was not persuaded by other actions.
