The correct answer is "megaloblastic anemia".
In the event of deficiency of folic acid and/or vitamin B12, there will be inhibition of DNA synthesis in red blood cell precursors as well as other cells in the myeloid lineage. This results to continuous cell growth without cell division leading to large, immature red blood cells (hence the term megaloblastic) with low hemoglobin levels. Vitamin B12 deficiency particularly causes neuropathic symptoms such as neuropathic pain and numbness.
If megaloblastic anemia is caused by the resection of the portion of stomach that produces the intrinsic factor (important in the absorption of vitamin B12), then the condition is called pernicious anemia.
The answers are
B. large grain sizes C. more precipitation D. warmer temperatures
More than 150 years ago, inventors began working on a bright idea that would have a dramatic impact on how we use energy in our homes and offices. This invention changed the way we design buildings, increased the length of the average workday and jumpstarted new businesses. It also led to new energy breakthroughs -- from power plants and electric transmission lines to home appliances and electric motors.
Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today.
Answer:
esta es una expresión de admiración ante la belleza de los mecanismos evolutivos
Explanation:
El concepto de evolución como mecanismos naturales que está actualmente en boga fue originalmente planteado por Charles Darwin en su celebre publicación "El origen de las especies" (1859). La teoría de la evolución de Darwin está basada en la idea que las especies cambian constantemente con el tiempo a través del proceso de selección natural. Este mecanismo es responsable de la inmensa biodiversidad biológica observada en la naturaleza, la cual incluye la evolución de las especies, poblaciones y organismos individuales. Desde una perspectiva biológica, es imposible no quedar fascinado ante la naturaleza y contemplación de los procesos evolutivos.
