Always contain Carbon
The majority of organic compounds contain carbon, hydrogen, and occasionally other elements such as nitrogen, sulfur, oxygen, or phosphorus.
<h3>What are Organic compounds ?</h3>
Organic compound, any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
- The few carbon-containing compounds not classified as organic include carbides, carbonates, and cyanides.
- Carbon is the key element because it has four electrons in an outer electron shell that can hold eight electrons

Answer:
macroevolution
Explanation:
Macroevolution occurs due to the genetic differences accumulates in the population of the same species which gets reproductively isolated from the older population and got different environments and resources to live.
Macroevolution leads to the creation of a new species over a long period of time because of the genetic difference that occurs due to mutation in the gene in the population who got reproductively isolated. So the new species evolved from the macroevolution.
Answer:
True each animal relies on one another. If one is affected then the cycle will be broken.
Explanation:
Answer:
This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
The most prominent organelle that contains genetic material and is visible in most eukaryotic cells is the Nucleus.
<h3>What is Nucleus?</h3>
- The nucleus is a double membraned organelle found in all eukaryotic cells.
- It is the largest organelle, which functions as the control center of cellular activities and is the storehouse of the cell's DNA.
- The nucleus is dark, round, and surrounded by a nuclear membrane.
- Within the nucleus, there are tiny spherical bodies called the nucleolus. It also carries an essential structure called chromosomes.
- So the nucleus is the organelle that is visible and present in all eukaryotic cells.
