Proteins are the only macronutrients that contain <u>nitrogen</u>, but carbohydrates, lipids, and proteins all contain the elements carbon, hydrogen, and oxygen.
- Nitrogen is a naturally occurring element that is necessary for both plant and animal growth and reproduction.
- It is present in many different chemical and inorganic compounds, including the amino acids that make up proteins, the nucleic acids that make up the genetic material and the blueprint for all organisms' viability.
- High-protein, high-purine foods like beef, shellfish, and organ meat are among the foods that contain a lot of nitrogen.
- For life to be nourished, renewed, and sustained, proteins are essential. Proteins contain the atoms carbon, hydrogen, and oxygen, much like carbohydrates and lipids do.

Answer:
a) introns
Explanation:
In molecular terms, a <em>gene</em><em> can be defined as a segment of DNA that is expressed to give a functional product, which can be an RNA or a polypeptide</em>. Large amounts of non-coding DNA can be found within the majority of eukaryotic genes. These genes have a divided structure in which the <u>segments of coding sequence (called </u><u>exons</u><u>)</u> are separated by <u>non-coding sequences (called </u><u>introns</u><u>)</u>. The complete gene is transcribed to produce a long molecule of RNA (called pre-RNAm) which will suffer a series of changes before leaving the nucleus. One of these modifications is called splicing, <u>in which the introns are removed</u>. Therefore, only exons are included in the RNAm.
The biochemical analysis of nuclear extracts has revealed that splicing occurs in big complexes, called spliceosomes, formed by small nuclear ribonucleoproteins (snRNPs) and 5 types of small size nuclear RNA (RNAsn).
Answer:
You are being asked to combine the sentences. (I am showing you an example using a conjunction.) You could write something like: "Back then, computers didn't use a mouse, <u>so</u> you had to type to open files"
Explanation:
There are quite a few differences that could count for this between plants and fungi. The first one would be the best characteristic:
1. Plants can make their own food via photosynthesis; fungi are obligated to get their food elsewhere so they can either be parasites and live off another living thing or they decompose matter to gain their energy.
2. So..fungi don't have chlorophyll...but plants do!
3. Plants reproduce through pollen and seeds - fungi make spores
4. Plant cell walls have cellulose whereas fungal cell walls have chitin.
5. Plants have roots, stems and leaves; fungi produce filaments which attach to a host (think of fungi you see growing on trees in the forest!)
