Answer:
Las ciencias naturales, ciencias de la naturaleza, ciencias físico-naturales o ciencias experimentales son aquellas ciencias que tienen por objeto el estudio de la naturaleza, siguiendo la modalidad del método científico conocida como método empírico-analítico. Son a veces referidas con el término de historia natural. Estudian los aspectos físicos e intentando no incluir aspectos relativos a las acciones humanas. Así, como grupo, las ciencias naturales se distinguen de las ciencias sociales o ciencias humanas (cuya identificación o diferenciación de las humanidades y artes y de otro tipo de saberes es un problema epistemológico diferente).
i am sorry if the answer is wrong i tried my best will u mark me as brainliest
Explanation:
Answer:
D
Explanation:
Normally if a scientist isn't present, more mistakes tend to occur and if there is a scientist, they can make more accurate claims and such.
Answer:
The invention of active drug loading method improves the encapsulation efficiency of some ionizable hydrophilic drugs (weak acid or weak base). The specific method is to construct pH gradient inside and outside the liposome, and then use the solubility difference of ionizable drugs under different pH conditions to realize the drug loading. With this method, the drug encapsulation rate can reach more than 95% and the drug loading can reach about 10%.

Im not so sure about this answer
Answer:
Option (3)
Explanation:
Unconformity is defined as the gaps in the sequence of geological rocks. It is a geological contact that marks the boundary between the different types of rocks. In simple words, they are also known as the time of non-deposition. These unconformities have great significance in the field of geology. They are of 4 types, namely-
(1) Angular unconformity- The sedimentary rocks are initially formed and deposited in an area, after that the area is tilted and erosion takes place. Now, the new sediments are deposited forming an angle, which is commonly known as an angular unconformity.
(2) Non-conformity- When the sedimentary rocks are deposited over the igneous or metamorphic rocks, then it is known as the non-conformity.
(3) Para conformity- When the sedimentary rocks are deposited parallel to the ground surface, and absence of erosion activity, then these surface appears to be a normal (simple) bedding plane. This is known as the para conformity.
(4) Disconformity- When the sedimentary rocks are formed and undergoes erosion, then new sedimentary rocks are deposited over this and diminishes the unconformity. This forms a discontinuity.
Thus, the unconformity arises due to both erosion and lack of rock deposition.
Hence, the correct answer is option (3).
