Answer:
Fossil records help scientists understand about how and when an organism might have evolved. It also helps determine how many evolutionary changes a particular specie might have gone through.
The long-term evolutionary patterns for a specie can be determined by fossils. Fossil record will help us analyze all the evolutionary changes that a species might have gone through to evolve into a particular type.
The gradual evolution of a species can be predicted if the fossil records show small, increment changes in the fossil patterns.
On the other hand, rapid evolution will result when there are no intermediate fossils depicted for a specie. That specie might have aroused due to a sudden change.
Answer:
Part 1. The amount of calcium is independent variable.
Explanation:
An independent variable is a variable in an experiment which is changed to see its effects on dependent variable.
In this experiment, to know about the causes of osteoporosis, the Ca level in blood or calcium intake in changed.
So the concentration of calcium will be independent variable.
Part 2.
The risk of bone fractures is could be changed with calcium.
Explanation:
In this experiment osteoporosis or risk of bone fracture is dependent variable.
Dependent variable are results of experiment which can be changed by independent variable.
As in experiment, Calcium concentration is independent variable.
So the risk of osteoporosis depends can change with calcium.
Answer:
its being called a miracle because mules aren't supposed to give birth haha, they're sterile, they can't make sperm or eggs because their chromosomes don't match up well, and coz of chromosomes number.
Explanation:
for example they have 31 and horses have 32 pairs of chromosomes so they cant match with anythin
Answer:
The correct answer is - all of the above.
Explanation:
If the cold and warm front collide the warmer air rises and colder air moves to the bottom due to the density of warm air is less than cold air which creates a front that is the boundary front of both fronts.
It forms a new front called an occluded front. The occluded front causes heavy precipitation, strong winds. and snow sometimes. In low pressures it also caused tornadoes.
