Answer:
B. In plants, there are no sister chromatids.
Answer:
1/12
Explanation:
Formula for calculating probability:
Probability of an outcome A =
Number of favorable outcomes of A / Number of possible outcomes
P ( A ) = number of favorable outcomes to A / total number of outcomes
⇒ The number of times 5 can appear when you roll the 12 sided cube once is one time = 1
⇒ The total number of possible outcomes is 12 - meaning you can roll any number between 1 - 12 when you roll the dice once. = 12
Therefore the probability of rolling 5 = 1 /12
Probability = 1 / 12
hope this help and brainiest please. thx
The Miller-Urey experiment is important because this was considered as the breakthrough in the study of origin of life, as to where and how exactly life began on earth and that it was possible to form organic molecules from inorganic molecules.

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.
Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.
For example, certain kinds of air pollution increase the rate of weathering. Burning coal, natural gas, and petroleum releases chemicals such as nitrogen oxide and sulfur dioxide into the atmosphere. When these chemicals combine with sunlight and moisture, they change into acids. They then fall back to Earth as acid rain.
