<span>The RNA world is the hypothesized format of chemical life that existed prior to our current DNA and RNA world. In the RNA world, RNA molecules formed in the primordial soup and began to evolve by self-replication and mutation. This led to increased complexity, natural selection of "better" RNA and diversification of RNA based life.</span>

Answer is A. B-hemoglobin mRNA is translated more efficiently than is a-hemoglobin mRNA.
Explanation:
The introduction of electric charge into a gel or fluid, causing or resulting in the movement of the charged particles in the gel or fluid, is referred to as the electrophoresis. It can also be explained as a separation method or technique which is based on the movement of particles or ions in an electric field.
The electrophoresis is used in separating DNA fragments , RNA or protein, based on their size and charge.
I think the answer is a sorry if I get it wrong
Answer:
B) If two non functional copies are inherited, the pea will be wrinkeld.
Explanation:
The gene for starch debranching is one of the genes that regulate more than one genetic trait. The starch debranching gene also regulates the seed shape in peas. The gene has two alleles. The allele B is completely dominant over allele "b" with respect to seed shape. Both homozygous and heterozygous dominant genotypes (BB and Bb) produce smooth seeds while homozygous recessive genotype (bb) imparts wrinkled shape to the seeds.
Secondary immunodeficiency is a deficiency or defect in body's immune system.
10 common diseases that can cause a secondary immunodeficiency are:
leukemia
diabetes
skin cell diseases
burns
virus infection
lymphoid malignancy
nephrotic syndrome
neutropenia
human immunodeficiency virus
protein-calorie malnutrition
There is no known way to prevent inherited immunodeficiency disorders. but there is some ways to prevent infection like get enough sleep, keep clean, manage stress, eat right etc.
