Answer:
Seeds disperse in four main ways, by air, water, animals and self propulsion:
Wind dispersal. Wind can carry seeds away from their parent plant.
Water dispersal. A few species use water to disperse their seeds.
Animal dispersal. Animals find fruits a rich source of food and as a result aid seed dispersal.
Explosion.
Explanation:
Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.
Answer:
Explanation:
Based on the information provided within the question it can be predicted that the population of the brown rabbits will diminish over time or may even go extinct, while the white rabbit population will thrive. This is because the white rabbits fur color allows it to better blend into it's environment and hide from predators, which in term leads to their survival as opposed to the brown rabbits which have nowhere to hide in the snow.
Surface tension is the property of water which allows for some lightweight insects to walk on top of a pond and not fall in. The molecules of water are held together by cohesive forces. The molecules of water present below the surface experience this cohesive force from all the directions, whereas the water molecules present on the surface experience a downward pull, as the force is not balanced. This leads to the concaving of the water surface inside a small tube.
B. Subgroups
<span>When constructing a dichotomous key, the first step is to look at the group of objects or organisms and separate them into two groups based on a single distinguishing characteristic. Then continue to separate each of the groups until each object has its own separate set of characteristics.</span>
