Answer:
1. Fossil record
2. Comparative anatomy
3. Embryology
4. Biogeography
Explanation:
Evolution is descent with modification. The organic evolution theory states that present complex life forms have evolved from the earlier (simpler) forms of life over time. Some of the most important pieces of evidence in support of the theory of organic evolution are:
1. Fossil record: fossils are dead remains of past living organisms preserved in the rocks of the remote past. These fossils demonstrate the existence of past living organisms that are related to present-day organisms.
2. Comparative anatomy refers to the study of similarities in the anatomy of different species, which provides direct evidence for identifying common ancestry between related species.
3. Embryology: the more recent the ancestor is that two species share, the greatest similarities in embryo structures and the more closely related the species are. In this regard, it is important to highlight that often homologous organs/structures (i.e., organs/structures descended from a common ancestor) can be observed only in embryos.
4. Biogeography refers to the spatial distribution of organisms and species. Species distribution reflects the evolutionary process when it is combined with geological change. For example, taxa that had already appeared before the separation of the continents are often distributed worldwide.
Answer:
C. There will be the same number of
protons and electrons.
Explanation:
Protons, represented by (+), have a positive charge.
Electrons, represented by (-), have a negative charge.
Neutrons, represented by (0), have no charge.
Any number of neutrons you have, they don't affect the charge.
If you have more protons than electrons, the charge will be positive.
If you have more electrons than protons, the charge will be negative.
When you have an equal number of the two, the charge is neutral.
Answer:
needs are something that you have to have in order to survive
wants are something you wish you could have, but it is not necessary
-needs are limited, but wants are unlimited
-needs may remain constant over time, but wants will vary over the time period of your life
-needs may actually result in death or illness if not fulfilled, but the want side of it will only result in disappointment
-needs are essential to your survival, but wants are not.

Answer:
Antoinette was diagnosed with hypertension, a noncommunicable disease in which her blood pressure is higher than normal. What is the most likely explanation for why she is hypertensive?
Antoinette condition which is hypertension could be as result of excessive stress and deep thought which makes the heart beat the work excessively by pumping more blood and over work the normal working rate.
Anxiety might also contribute to such as well, life burden could enable Anoinette to have such condition.
