The answer is anaphase.
Ron is obviously observing cell division - mitosis. Mitosis consists of four phases - prophase, metaphase, anaphase, telophase and cytokinesis.
1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up
2. Metaphase: Chromosomes line up at the center of the cell. The sister chromatids are joined together.
3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.
4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.
Therefore, sister chromatids being are pulled to the opposite ends of the cell in anaphase.
b. live in trees
c. are harmful to trees
d. none of the above
Answer:
The correct answer is option b, that is, live in trees.
Explanation:
The arboreal animals refer to the animals that devote the majority of their lives in trees. This animal group eat, play, and sleep in the canopy of the tree. Some of the examples of arboreal animals are tree snakes, monkeys, koalas, parrot sloths, possums, and various rodents.
These animals exhibit unique adaptations like long feet and claws, long tails and elongated limbs, and unique movement patterns, which help them to thrive in their arboreal lifestyles.
He determines that it has a nucleus and lysosomes. It also contains a cell membrane, but does not have a cell wall.

Latitude and longitude spatial variation of temperature affects climate and then the distribution of biodiversity.
Biodiversity is defined as the diversity of all living things such as different plants, animals and microorganisms, the genetic information contained in them and the ecosystems they form which are generally explored at three levels - genetic diversity, species diversity and ecosystem diversity.
Biodiversity is essential to the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we could not have the healthy ecosystems we rely on in the air we breathe and the food we eat and the people who value nature. This is affected by latitude and longitude variation of temperature.
Thus, Latitude and longitude spatial variation of temperature affects climate and then the distribution of biodiversity.
