Answer;

-Carbon

Explanation;

-Fossils are formed in a number of different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. They formed from organic remains of plants and animals that were converted into coal, oil or natural gas by exposure to heat and the pressure of the Earth’s crust over millions of years.

-Fossil fuels are hydrocarbons comprised primarily of the following elements: carbon and hydrogen and some sulfur, nitrogen, oxygen, and mineral matter. For example, Natural Gas and coal are made up of carbon, hydrogen, nitrogen, sulfur and oxygen. Oil, or petroleum, also consists of carbon, hydrogen, sulfur, oxygen and nitrogen, but it is in liquid form.

What cycles through an ecosystem, but energy doesn’t. Explain why this is true
Alexxx [7]

Answer:

Energy does not cycle the way nutrients and atoms do. Energy enters the ecosystem from the Sun and exits after the organisms have taken as much as they need. Organisms release energy back into the biosphere as heat.

Chromosome 21 figure D is the result of a process known as________
Softa [21]

Answer:

Chromosome 21 in figure D is the result of a process known as non-disjunction

Explanation:

Meiosis is the process of cell division that serves to obtain gametes, cells with exactly half the chromosome load of the species. This process involves the equal distribution of chromosomes in each daughter cell.

Non-disjunction is an alteration in the separation of the sister chromatids during meiosis, resulting in a gamete with non-separated sister chromatids, which when joined to a normal gamete can produce an organism with an extra chromosome.

In the karyotype shown in the photo, the non-disjunction in chromosome 21 produces a trisomy, a type of aneuploidy seen in Down syndrome.

Help! Will give brainliest to the best answer.
ohaa [14]
A nonnative species may not have any natural predators when being introduced subsequently it won’t have any competition with the other organisms living in the same ecosystem. This will make the other organisms struggle for food and other resources and could potentially make them go extinct. They can also have drastic effects to the local biodiversity (for the previous reason). Also, due to the competition or newly introduced predator (assuming they’re a predator) the preexisting organisms of the ecosystem may start to relocate and start a new ecosystem or if there are neighbouring towns/cities may have to forage for food there - which would obviously be dangerous for both them and us. Hope these few examples help.
