Answer:
Cells are the simplest structure to fit all of the characteristics necessary to be considered alive.
Explanation:
The cell (from the Latin cellula, diminutive of cella, ‘hollow’) 1 is the morphological and functional unit of every living being. In fact, the cell is the smallest element that can be considered alive.2 In this way, living organisms can be classified according to the number of cells they possess: if they only have one, they are called unicellular (such as protozoa or bacteria, microscopic organisms); If they have more, they are called multicellular. In the latter the number of cells is variable: from a few hundred, as in some nematodes, to hundreds of billions (1014), as in the case of the human being. The cells usually have a size of 10 µm and a mass of 1 ng, although there are much larger cells.
Answer: The statement is correct in scientific sense.
Explanation:
Adaptation refers to the traits or characteristics posses by living organisms which enable the organisms to be better fitted to survive, and reproduce in it's environment.
Adaptation is an evolutionary process I.e. features are evolved by the organisms to be better suited in it's environment.
From the statement, an individual crab develop characteristics that enable it to change its position which enable it upright stance to further adapt to life in land.
Answer:
"Folded sedimentary layers were originally laid down flat and later deformed." describes the law of original horizontality.
Explanation:
In terms of structural geology, the folds happens when the one over the another are piled up on a flat as well as planar structure i.e. sedimentary strata. Which sometimes are bent or may be curved because of the permanent deformation. Both upward as well as downward folds occurs in the sedimentary fold. Which is known as the anticline or the syncline. There are three major folds in case of the sedimentary layers they are monocline, anticline and syncline. Simple bend layers are called as the monoclines.
