Answer: option A, B and D
Explanation:
The telomeres found at the terminal ends of eukaryotic chromosomes are long repetitive sequences that protects the DNA from being identify as a damage molecule to encourage fusion with other chromosomes. Since replication does not extend down to these 3' ends, the cell recruits the telomerase enzyme which is a ribonucleoprotein that helps to add telomeric repeats using its own RNA component as template to extend this end. Thus if mutation like a large deletion occurs in the gene encoding for this enzyme, the telomerase would not be able to associate correctly with the telomere, the catalytic center also encoding for its RNA polymerase would be altered and the enzymes will not be able to synthesize new telomeric repeats sequences
Explanation: we will conclude this by the following characteristics:
1.organims that lack a proper nucleus.
2.they have membrane bounded organelles
3.they are tiny single cell oraganisms which cannot be seen by naked eye.
4.they are the oldest livinh organisms on earth
5.they are present in very harsh conditions like volcanic vents or at the bottom of the sea
Anti-D immunoglobulins or anti-D (RH) immunoglobulins are a variety of immunoglobulins (IgG). These are proteins that play an important role in our immune system.
Anti-D immunoglobulins are obtained from human blood taken from volunteer donors. They are administered in the pregnant woman in case of incompatibility of rhesus between her and the child.
The CPT codes are:
90384 an 90385 for intramuscular use
.
90386 for intravenous use.
The icd-10-cm code is Z29.13.
Answer:
Al introducir una piedra en agua, está se va al fondo del vaso, por que es más pesada que el agua
Al introducir un bolígrafo, este flota, por que es más liviano que el agua
Si se introduce en agua un tajalapiz se evidenciará un proceso de corrosión del metal
Debido a la reacción con el agua, sin embargo el efecto será más evidente si se agrega sal a la mezcla
