Nucleotides are monomers composed of sugar and phosphate groups and a nitrogenated base. Several nucleotides compose DNA and RNA.

<h3>What are nucleotids?</h3>

Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.

Monomers are composed of carbon, oxygen, and hydrogen atoms, which establish covalent bonds.

Several monomers comprise a polymer. In this way, several nucleotides joined by their extremes compose the nucleic acids.

Nitrogenated bases are molecules carrying nitrogen and exhibiting the chemical properties of a base. These are purines and pyrimidines.

DNA ⇒ Adenine, Guanine, Thymine, and Cytosine.

RNA ⇒ Adenine, Guanine, Uracyl, and Cytosine

Adenine pairs with thymine or uracil, while guanine pairs with cytosine.

Sugar group: Sugar is always a pentose.

DNA sugar group contains deoxyribose, with hydroxyl modifications.

RNA sugar group contains ribose with no hydroxyl modifications.

Nucleotides have a certain order or sequence in nucleic acids, which is significant since these sequences carry biological information necessary to carry out cellular functions.

Identify the fluid filled space between the cornea and iris

hichkok12 [17]

Answer:

Anterior chamber.

Explanation:

Anterior chamber fluid filled space between the cornea inner most surface called as endothelium and iris inside the eye. Cornea is the transparent, outer, and dome like structure. Its helping in to cover iris, anterior chamber, and pupil. Iris is coloured, flat, and ring shaped membrane present behind the cornea along with pupil in the center of the eye.

Anterior chamber is filled with the fluid which is called as an aqueous humor. It is produced by the capillary body alongside the lens. The fluid first passes between the lenses and iris known as posterior chamber, and then with the help of pupil into the anterior part of the eye.

Dry matters is made up of organic matter and?

Otrada [13]

Dry matter is what remains after all of the water is evaporated out of a feed: grain and fresh or dried forages. Fresh pasture has high water content and will have a lower percentage of dry matter than an equivalent weight of dryer feed, such as hay or grain. Dry matter is an indicator of the amount of nutrients that are available to the animal in a particular feed.

Livestock need to consume a certain amount of dry matter per day (measured in lbs or kg/day) to maintain health and production. The daily amount of dry matter needed depends upon several factors including, weight and stage of production (e.g., lactating, pregnant, weaning, finishing). Dry matter intake (DMI) can be estimated by using published reference tables that provide the percent dry matter in various dry (hay and grain), fresh, and ensiled feeds. There are also methods to measure the actual dry matter in feed.

Under the NOP regulations, ruminants must obtain at least 30% of their dry matter intake (DMI) from grazing on pasture during the grazing season.
