. In mitosis the nuclear membrane breaks down and the centrosome
Answer:
B.
Explanation:
The resistance to sudden temperature changes makes water an excellent habitat, allowing organisms to survive without experiencing wide temperature fluctuation. Furthermore, because many organisms are mainly composed of water, the property of high heat capacity allows highly regulated internal body temperatures.
I'm pretty sure it's B . If I'm not I'm very sorry as I copied this from my textbook .
B. because natural selection is when the environment causes an organism to evolve, the climate becoming colder and wetter would likely overtime cause the rats to have thinner hair and have skin that can handle staying wet more
Answer:
In simple terms, the metric system (which is the same as SI) is important because it's more coherent than the imperial system.
Explanation:
The metric system is far more used worldwide compared to the imperial system, where the imperial system is only officially used in three countries (U.S, Liberia, Myanmar).
There are multiple reasons why the metric system is important, but the most critical reason is that it's very easy to understand pertaining to calculations. The measurement system of SI is <em>designed</em> to make measurements/calculations easy to perform and understand. This is why scientists prefer using the metric system over imperial.
You can make some small comparisons:
--> Metric is consistently based on decimal numbers, while imperial uses different number systems (base 3, 8, 12, 14, 16, etc.,)
--> Metric works well with percentages, while imperial does not
--> Metric units are the same internationally, while some imperial units differ (i.e different pints, gallons, tons, etc.,)
There are fewer, simpler measurements in the metric system as compared to imperial where calculations start to get overcomplicated due to the amount of measurements/units in the system.
In layman's terms... metric is a boat on smooth water with perfect weather, while imperial is a boat on rough waters during a storm.
Answer:
(B) Similarities among Hox genes suggest that they all arose from a single ancestral gene that duplicated many times.
Explanation:
Hox genes are arranged in clusters and their order on the chromosome is the same as the order in which they are expressed along the body during development.
I hope I helped, and I always appreciate Brainliest!!! :)
