Answer: Carbon is the most important element in organic compounds, which means that life on earth is possible thanks to this atom and its characteristics. Below you can see some of the ones I consider to be the most relevant

Explanation: Carbon atom has 6 protons and 6 neutrons in its nucleus, and that nucleus is surrounded by 6 electrons. Those electrons are distributed two in their first level (called s) and four in their second level (called p).

It is tetravalent, because it has 4 electrons orbiting its last energy level, which can be combined with other atoms, even with another carbon atom forming covalent bonds. , present in all the organic compounds.

Thanks to these electrons, it can form three hybridizations or types of junctions; single, double or triple. This is important for molecular geometry: the single bond determines the formation of a tetrahedron, with angles of 109.5 ° , the double bond determines the formation of a flat triangular structure, with 120 ° angles and the triple bond determines the formation of a linear structure, with 180.

This are some of the most importan characteristics tha make Carbon a unique element.

The methodology used to discover the pattern of evolution among an assemblage of species is based on the assumption of descent w

Shtirlitz [24]

Answer:

Option-(True): The methodology used to discover the pattern of evolution among an assemblage of species is based on the assumption of descent with modification.

Explanation:

Evolution and patterns of evolution:

The phenomenon of evolution is very interesting as it can any two different species back to a common origin or ancestors. While the process of evolution does not occur in few years or centuries, as it takes millions of years for any specie to evolve from a less developed form of body or any system to a more complex or advance form.

Now, evolution occurs in many forms or patterns. As it species can originate from a single ancestor or descendant, while the evolution can occur inside the organism may occur in different patterns. These patterns are as follows:

Divergent Evolution:The divergent evolution occurs when the species originated from a single ancestor or descendant results in different forms of organisms. As it brings diversity among the species belonging to same ancestors or origin. For example, the humans and apes.
Convergent Evolution: The convergent evolution takes place inside the number of species when they are originated from the different species but they share the same medium or region to live in and share some of the similar resources between them. For example, The whales are mammals but they too live with the fish species inside the water.
Parallel Evolution:When the evolved organisms or species are related to the different ancestors or descendants, as they share they do not share the same niche(way of life), as the species are unrelated to one another.

What is an angiosperm? Provide 2 examples. PLEASEE

kvasek [131]

Answer: Angiosperms represent approximately 80 percent of all known living green plants. Examples range from the common dandelion to ancient flowers such as magnolias. Angiosperms also make up the vast majority of all plant foods we eat. (Ex. grains, vegetables, and fruits.) The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary The ovary itself is usually enclosed in a flower, that part of the angiospermous plant that contains the male or female reproductive organs or both. fruits are derived from the maturing floral organs of the angiospermous plant and are therefore characteristic of angiosperms.
