Describe the chemical components of DNA.
Slav-nsk [51]

DNA is composed of nucleotides, which are composed of three parts:

1. A five carbon carbohydrate (pentose)

Pentose is classified as a monosaccharide (simple carbohydrate), and its molecular formula is represented by (CH_{2} O)n. They are water soluble molecules with sweet taste. Monosaccharides may have from three carbon atoms (trioses) to six (hexoses). In DNA is present pentose (5 carbon atoms)

2. A nitrogenous base

Nitrogenous bases are ring-shaped compounds that contain nitrogen in their molecular structure. They are classified into two groups: purines and pyrimidines

The purine bases are adenine (A) and guanine (G). They are larger and contain more than one ring in their structure,.

The pyrimidines, cytosine (C), uracil (U) and thymine (T), are smaller and composed of a single ring.

3. One or more phosphate groups

A phosphate consists of a trivalent anion that contains one phosphorus atom and four oxygen atoms. Its molecular formula is expressed by (PO_{4} ^{-3}).

Zepler [3.9K]

Answer:

a shared derived trait.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, weight, handedness, freckles, curly hair, hair color, blindness, complexion, height, etc.

All humans and baboons are created having noses with nostrils underneath i.e facing downwards but other primates such as platyrrhines have their nostrils facing sideways (face out to the side). Also, humans and baboons shared close similarities with each other when compared than they share with the primates having a outward-facing nostrils.

This ultimately implies that, both humans and baboons sharing the downward-facing nostril orientation is an example of a shared derived trait.

A shared derived trait can be defined as a trait or characteristic that is shared between two lineages and subsequently evolves leading up to a clade, which is a distinguishing feature from other species.

Anton [14]

Answer:

Put the cut portion in vertical upward position and cover it with clean tissue or cloth.

Explanation:

At first to minimize the bleeding from wrist we need to raise the wrist up and then apply pressure by clean tissue or cloth. Wrap the tissue/clothe around the wrist. If blood is soaking through the material wrapped, don't remove the wrap but pot more tissues/cloths around the wrap and continue to apply the pressure. The hand should be kept raised at a level more than the level of heart of that injured person. Due to continuous pressure of the wrapping material the bleeding will stop in around 5-8 minutes.
