Answer:
Yes, they are living things. How? Well I did my research with my browser and it doesn't have a lot to say but what it does say is That it is living.
Explanation:
Answer:
systematics is the correct answer.
Explanation:
- The modern approach to classification, with the broader goal of reconstructing the evolutionary history, or phylogeny, of organisms is: systematics.
- Systematics plays an important role in the field of biology.
- Carl Linnæus is the father of Systematics.
- Systematics refers to the study of the diversification,nomenclature, and classification of the living organism in the past and also in present.
- Systematics is used to understand the evolutionary relationship and the purpose of systematics is to describe and explain biological variety.
- The main objective of systematics is to identify species and to give scientific names to organisms, it used to determine the arrangement of the living organism and to study the evolutionary history of organisms.
The optic nerve carries impulses to the thalamus and ultimately to the visual cortex of occipital lobes.
The optic nerve is a paired nerve, and part of the central nervous system that transfer visual messages from the retina to the vision areas of the brain through electrical impulses. The optic nerve is situated behind the eye and it is made up of retinal ganglion cell axons, glial cells and over one million nerve fibers.
1. 118
2. It consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po). synthetic elementlivermorium (Lv)
3.same number of valence electrons
4. 8 because it has full valence shell
5. Halogens are the compounds found in group 17 of the periodic table. They are all incredibly electronegative, meaning that they are very willing to take electrons from other atoms. Fluorine, for example, is the only element that can take electrons away from oxygen.
Alkali metals, on the other hand, are just the opposite: Their electronegativity is very low, meaning that they are very willing to give away electrons
Both groups are highly reactive.
6. atomic number is the number of protons
7. a Columb of elements in a periodic table
8. a row of elements in the periodic table
