c. Birth rates are high
Explanation:
A wide base in the population pyramid shows that there is a large population of young people with high fertility rate or birth rate and high death rate.
From the graph, it can also be concluded that narrow tip at the top shows that lesser older people are in the population.
This pyramid shown in the diagram is a triangular age pyramid. In this type of pyramid the pre-reproductive individuals are high reproductive individual are moderate and non-reproducing individual is less. In such pyramid we find population grows.
Suppose in a family of ten 6 are pre-reproductive, 2 moderate reproductive and 2 post-reproductive. We will see the in the course of moderate and post-reproductive will die and those six of pre-reproducing age will increase the population.
Answer:
The modern view of electric charge is that it is a basic property of atoms, the fundamental particles of which all matter is made. Atoms themselves are composed of three different types of particles—protons, neutrons, and electrons.
Explanation:
The answer is 3 phenotypes. These are the homozygous
dominant, homozygous recessive and heterozygous. In incomplete dominance, the
dominant traits do not fully mask the recessive
gene (note this is different from co-dominance). Example of incomplete dominance
in humans is the alleles for straight and curly hair. Heterozygous for this trait is wavy hair due to incomplete dominance.
<span>Chromosomes are visible at any time but are most easily seen through a simple microscope when they meet at the plate during the metaphase stage of mitosis because the chromosomes are jumbled together and then form the traditional X-shape.
They are easy to see because a single strand of DNA from H. sapiens is about 6 feet long!
Good luck on that test of your and i hope you past the test</span><span />
