Answer:
A. Obligate
Explanation:
An obligate relationship is one where both organisms are interdependent with one another in a way that one cannot survive without the other.
A parasitic relationship is where one organism benefits, and the other is harmed.
A mutualistic relationship is one where both organisms "work together," therefore benefiting one another.
A facultative relationship is where both species benefit off of one another, but are not fully dependent on one another to the point they cannot survive without their symbotic partner.
BMPER serves as a protein which is found in humans and it is been encoded by the BMPER gene.
Yes, the discovery come from basic or applied science because the discovery as a result of observation through research and can be proven with evidence which is what science is based on.
<h3>What is BMPER?</h3>
Bone morphogenetic proteins (BMPs) can be described as one that is found in embryonic and adult blood vessel formation which is been used in health .
BMPER serves as a differentially expressed protein that can be found in the embryonic endothelial precursor cells.
It should be noted that BMPER can carry out some interactions with BMPs, and in the case whereby they were overexpressed , they will antagonizes their function in embryonic axis formation.
Therefore, BMPER serves as a protein which is found in humans and it is been encoded by the BMPER gene.

A) Chargaff discovered two rules that helped to reveal the structure of the double helicon DNA. Chargaff's rules claim that the DNA from any cell and any organism should have a 1: 1 ratio (base pair rule) of pyrimidine and purine bases, and more specifically that the amount of guanine is equal to the amount of cytosine, and the amount of adenine is equal to the amount of thymine. This form was found in both DNA strands.
B) James Watson and Francis Crick in 1953 proposed the first correct model of the double helicon DNA structure. Their model was based on only one X-ray diffraction image recorded by Rosalind Franklin and Raymond Gosling in May 1952, as well as information that the DNA bases ware paired, which came out of private communication with Erwin Chargaff during the previous years. Chargéff's rules played a very important role in determining the configuration of double helices for B-DNA as well as for A-DNA.
From the polymers listed, the ones which are found in natural sources are: protein, cotton and silk.
A polymer is a large molecule composed of many repeated subunits. Many small molecules (monomers) are bound by chemical reactions, called polymerization, and form the polymers. Polymers are widely used in many applications and they can either be synthetic or naturally occurring biopolymers. In the provided list, polypropylene, polyvinyl chloride and nylon are synthetic polymers. Polypropylene and nylon are thermoplastic polymers, and polyvinyl chloride (vinyl) is a plastic polymer. On the other hand, proteins are naturally occurring polymers produced by many amino acids. Cotton is formed by repeating units of cellobiose and it is a naturally occurring cellulose polymer. Finally, silk is a polypeptide and a linear fibroin polymer.
