Answer: One red blood cell will be able to carry one billion molecules of oxygen.
Explanation:
If each red blood cell carries 250,000,000 hemoglobin and every molecule of hemoglobin binds four oxygen molecules, the number of oxygen molecules carried by one red blood cell is 250,000,000 x 4 = 1,000,000,000. That is 1billion oxygen molecules is been carried by one red blood cell. Hemoglobin is a protein present in the red blood cell which binds and transports oxygen to the cells throughout the body. Hemoglobin has four binding sites for oxygen. The binding of one oxygen to its binding site on hemoglobin increases the binding affinity of subsequent oxygen molecules to the other binding sites on the hemoglobin. This phenomenon is known as cooperativity.
Answer:
it demostrate thatcellulose starch and carbohydrate are essential for plants
Explanation:
Rust is the term we use to describe red iron oxides produced when ferrous metals corrode. Rust is the common name for the chemicals that result when iron reacts with oxygen and water. “Rust” is poorly defined in chemistry, however—lots of chemicals can be formed when iron is left exposed.
I think the correct answer from the choices listed above is option A. The first type of cell to differentiate is a neuron. The neurons are cells that process and transmits information through electrical and chemical signals. Hope this answers the question.
The answer is: insert the gene responsible for larger sized kernels into the genome of the corn with smaller sized kernels and a high yield.<span>
The techniques of genetic engineering are used to introduce hybrid genes for some desired substance or trait into the genome of other organisms. Here, the desired trait is larger sized kernels. So, the gene responsible for this trait will be inserted into the genome of the corn </span><span>with smaller sized kernels and a high yield.
It should be taken into consideration why two other choices are not correct:
1. there are no genes for less or more of something in the genome.
2. genes are part of a genome, so the genome for a trait cannot be inserted into a gene of an organism.</span>
