Answer:
A (Genotype)
Explanation:
All organisms possess genetic material which contains information required for certain functions/traits. This genetic material is stored as DNA and contains certain segment that encodes functional products (proteins) called GENE. The make-up of the genes responsible for a particular characteristics in an organism is called the GENOTYPE. Genes occur in variant forms called ALLELES, which are inherited from each parent.
These alleles are responsible for the varying expression of a particular trait e.g. allele T can be responsible for Tallness while the variant form, allele t can be responsible for shortness. In this example, we can see that height is the trait here but the different alleles encode varying expression of it. The combination of the alleles received by both parents, which collectively determines the trait to be expressed is the GENOTYPE.
N.B: The genotype refers to the physically invisible genes not the expressed trait itself, which is the phenotype.
In this case, an allele (gene variant) is responsible for the resistance of Red Blood cells and regulates oxygen carried by them. The phenotype is the resistance that the RBC's possess and its reduced ability to carry oxygen but the combination of alleles responsible for that trait is the GENOTYPE.
Cations are positive so they have less electrons than protons, while anions are negative so they have more electrons.
<span>In analyzing the role of proteins in the cells of living organisms, it is clear that they have a broad array of functions. This ranges from controlling reaction rates that occur within the cell, to transporting important information and carrying out crucial processes.</span>
Two methods of producing transgenic mice are widely used: transforming embryonic stem cells<span> (ES cells) growing in tissue culture with the desired DNA; injecting the desired gene into the pronucleus of a fertilized </span>mouse<span> egg.</span>
Definition : "Cellular respiration<span> is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products."
Simplified : </span>Cellular respiration is used to take in food, then is used to create ATP. ATP is a chemical the cell uses for energy. This process is called aerobic respiration. The process uses oxygen, and has four stages known as Link reaction, glycolysis, the Krebs cycle, and the electron transport chain.
You might want to re-word the simple version a little, I worded it the best I could but I used information from wiki.
