7. Stress is the force applied to a rock, which may cause deformation of the rock. There are three major types of stress and go along with the three types of plate boundaries; Compression stress is common at convergent boundaries, tension stress at divergent boundaries, and the shear stress at transform boundaries. In this case the rocks have undergone tensional stresses.
8. Horst is a raised fault block bounded by normal faults. A horst is a raised block of the Earth's crust that has lifted, or has remained stationary, while the land on either side (garben) has subsided. Therefore the structure labeled A in the diagram is Horst.
9. A Graben; it is a valley with a distinct escarpment on each side caused by the displacement of a block downward. It often occurs side by side with the horsts. Horst and Graben structures indicate tensional forces and crustal stretching. Therefore, the structure labeled B is Graben.
When cells get too large, they not cannot properly expel waste or bring in enough nutrients, and so they begin to fail. In organisms, especially humans, mitosis divides the cells.
Interphase: cell is growing and going through normal functions
Mitosis: cell's genetic material and nucleus divide
Prophase: chromatin condenses, nucleus breaks down, centrioles move to opposite sides, spindle forms and pulls sister chromatids apart
Metaphase: spindle fibers move to the middle of the cell
Anaphase: sister chromatids separate, spindle shortens, pulling chromatin to opposite sids
Telophase: chromosomes reach opposite sides and uncoil,nuclear membrane forms around genetic material again
Cytokinesis: division of the cytoplasm
End Result: two genetically identical cells
The correct answer is: a. in photosynthesizing cells in dark periods and in other tissues all the time
Cellular respiration is a process, more precisely set of metabolic reactions used to convert biochemical energy from nutrients into energy (ATP). One of the steps in cellular respiration is oxidation of pyruvate that occurs in mitochondria of all cells.
During the dark period only respiration takes place (oxygen is used, carbon dioxide is reeased). But, during daytime when the light is bright, photosynthesis in photosynthesizing cells produces oxygen and glucose faster than respiration consumes it.
Answer:
DNA strands consists of four nitrogenous bases, pentose sugar and a phosphate group. The DNA strands are complimentary with each other as thymine binds with adenine with two hydrogen bonds and guanine binds with cytosine with three hydrogen bonds.
The given DNA strand for cystic fibrosis is 5'......ATAGCAGAGCACCATTCTG.....3'. Its complimentary DNA strand in 3'......TATCGTCTCGTGGTAAGAC......5'. The DNA strands of 5'.....CAGAATGGTGCTCTGCTAT........3′. The dots before and after the given sequence represent that the given strand is a shirt stretch of the DNA made of large number of nucleotides.
