Ill say B poor soil Because how would you grown vegetation with out good soil
<h2>Postulates of natural selection</h2>
Explanation:
- Early in development, all vertebrate embryos are remarkably similar. The similarities among the embryos imply that the development of all vertebrates (having a backbone) evolved as new genetic instructions were placed on Top of older ones.
- The chick embryo is on the right. It is easier to compare a newly hatched chick and a newborn baby. After birth, a backbone or vertebrae are clearly visible, as are legs, a mouth, a pair of eyes, etc. The chick’s Skeletal system, in general, has multiple similarities to ours, including having one bone in the upper leg and upper wing and two bones in the lower leg and lower wing. This mimics our arm and leg skeletal structures.
- Mammals, birds, reptiles, and fish, look very similar at the earliest stages of growth inside the womb of the mother animal.Vertebrate embryos begin developing similar features due to related ancestors. As the embryo grows, it may drop some of these ancestral traits as the genetic code becomes more specific for that species.
Anatomical terminology. Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
Answer:
Genetic drift
Explanation:
Genetic drift is an evolutionary mechanism that in a population it changes allelic frequencies over generations just by chance. For this reason, small populations are more susceptible to be affected by genetic drift than bigger populations.
In this example, Indiana Jones visited a small village of 50 people and over generations allele A probably was lost just by chance, or by genetic drift.
Answer:
Baking soda in vinegar
Explanation:
Cause soda is a base and vinegar an acid which will neutralise each other
