Which of the following is a source of energy made from plant and animal remains?

Answers

Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.

In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.

These are sometimes known instead as mineral fuels.

The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.

Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.

The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.

A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.

How are traits inherited by offsring?

Answers

answer:
a trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. If a gene pair contains a dominant allele, then the offspring will show this dominant trait.

step by step:

Answer:

Traits are passed to offspring by the offspring parents.

Explanation:

the genes that control a trait come in pairs, one from each parent. If a gene pair contains a dominant allele (a variation of genes that will produce phenotype,) than the offspring gains that trait from the dominant parent.

How many chromosomes are there in
gametes?
HALF the amount of normal cells
The same amount as all other cells
DOUBLE the amount of normal cells

Answers

Half the amount of normal cells. These are called haploid cells, or gametes. Gametes include sperm and egg. When the egg (23) gets fertilized by a sperm (23), you create your first diploid cell (46) called a zygote. This zygote then undergoes mitosis to become an embryo, and then eventually a baby child. That child continues to undergo mitosis until it has developed into an adult.

Answer:

HALF (23) the number of normal cells (46).

Camptosaurus

Triceratops

Theodont

Tyrannosaurus

Answers

Answer:

camptosaurus

Explanation:

I think it's correct

The Dinosaur that most likely evolved from Coelophysis is known as Camptosaurus. Thus, the correct option for this question is A.

What is Evolution?

Evolution may be characterized as the complete methodology of gradual change that takes place over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.

Coelophysis lived during the late Triassic period some 216.5 to 203.6 million years ago. Researchers believe that this small theropod lived on river floodplains where it walked alongside crocodilian-like Camptosaurus. They were small theropod dinosaurs that lived in what is now North America and Southern Africa during the late Triassic.

Therefore, the Dinosaur that most likely evolved from Coelophysis is known as Camptosaurus. Thus, the correct option for this question is A.

Answers

Answer:

―CHO

Explanation:

Organic compounds are compounds that contain carbon-hydrogen bonding in their structural formula, hence, virtually all organic compounds are referred to as HYDROCARBONS. Organic compounds consists of a wide variety of groups, which are individually identified by their FUNCTIONAL GROUP.

The functional group of an organic compound is responsible for its chemical behavior irrespective of other atoms in its structure. According to this question, ALDEHYDE GROUP is an organic compound also called ALKANAL. It has the functional group as follows:

R - C - H - O

Where R is a side chain

- The second member of the aldehyde group is called ACETALDEHYDE with the chemical formula; CH3CHO. Since it is a member of the aldehyde group, its functional group is -CHO.
