Answer:
Option (B).
Explanation:
The process of cell differentiation in the embryonic stage is important for the cell to differentiate into a specific cell type. The cell differentiation also occurs in the adult stages also.
Various experiments have been done to find the evidence of cell differentiation. The occurrence of the specific mRNAs for the formation of tissue specific proteins provide the evidence that cell differentiation occurs in the embryonic stage.
Thus, the correct answer is option (B).
a. Sugar cane, corn, carbgrass which are identified as C4 Plants allow fixation of carbon dioxide into four carbon compounds. This happens during the hottest time of the day - their so-called stomata gets partially closed. C4 plants have been identified to lose only half of the water that C3 plants lose when they produce the similar amount of carbs.
<span>b.CAM PATHWAY - Plants such as pineapples and cactus have different approach to adapting heat. Carbon is fixed through a cam pathway. They use it to open their stomata at night and close it in the morning.</span>
A group of similar ecosystems with the same general type of physical environment is called a Biome
Answer:
Un terremoto con la misma magnitud y profundidad podría causar daños drásticamente diferentes dependiendo de la vulnerabilidad de la exposición. Por ejemplo, un terremoto M6 en California o Japón podría causar muy poco daño debido a las estrictas disposiciones sísmicas de los códigos de construcción. Mientras se encuentre en un país del tercer mundo, el daño podría ser catastrófico y se podrían perder millones de vidas.

Answer:
-Option (d).
Explanation:
BFB (breakage-fusion-bridge) cycle can be defined as a mechanism associated with chromosomal disabilities. The breakage-fusion-bridge cycles are associated with tumorigenesis as it induces chromosomal abnormalities in cells.
It starts with breakdown of chromosomal end region (telomere). When that chromosome goes for replication, daughter chromatids formed by it lack telomere.
During anaphase, fused chromosomes get separated and each daughter cell gets a chromosome without telomere. These mutated daughter cells replicate again and as this process rerun, it can lead to accumulation of chromosomal instability and tumor formation.
Thus, the correct answer is option (D).
