Answer:
Skeletal muscles are long and cylindrical in appearance; when viewed under a microscope, skeletal muscle tissue has a striped or striated appearance. The striations are caused by the regular arrangement of contractile proteins (actin and myosin). ... Skeletal muscle also has multiple nuclei present in a single cell.
Explanation: Hope this helps. :)
Answer:
Because the leading strand is synthesized continuously while the lagging strand is discontinuously synthesized.
Explanation:
Two DNA strands have opposite polarity, that is, the 5' end of one strand lies opposite to the 3' end of the other strand. However, DNA replication can occur in 5' to 3' direction only since the formation of phosphodiester bonds require the presence of nucleophile 3' OH to attack the 5' phosphate of an incoming deoxyribonucleotide.
The problem is solved by the synthesis of the leading strand continuously and the synthesis of the lagging strand in a discontinuous manner. Lagging strand synthesis requires the formation of primers and their elongation to form Okazaki fragments that may have few hundreds to few thousands of nucleotides. Removal of primers from Okazaki fragments is followed by joining them together to make the long lagging strand. The discontinuous replication of the lagging strand makes the replication at the leading strand ahead of it.
Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. biomass is the total mass of organisms at a trophic level.
Answer:
D. It produces gametes / sex cells.
Explanation:
Meiosis is a reductions division, so the source of the sex cells will produce the gametes, undergoing meiosis. The gametes will have half the number of chromosomes in a human body (23).
Answer:
una medición debe ser precisa y objetiva ya que sólo de este modo es posible reproducir el diseño experimental en condiciones controladas
Explanation:
Las ciencias experimentales son aquellas que realizan estudios en condiciones controladas (experimentos) con el objetivo de comprender el mundo natural que nos rodea. La medición juega un papel crucial en las ciencias experimentales ya que sólo una medición precisa y objetiva permite reproducir los resultados obtenidos en diferentes experimentos. De este modo, el proceso de cuantificar magnitudes está directamente asociado a la confiabilidad de los datos obtenidos en un experimento y consecuentemente también a la confiabilidad de las conclusiones derivadas de la aplicación del método científico experimental.
