PIT_PIT [208]

The answer is C.

Transgenic means that one or more DNA sequences from another species has been introduced by artificial means. For example, animals usually are made transgenic by having a small sequence of DNA injected into a fertilized egg or developing  embryo. Transgenic plants can be made by introducing foreign DNA into a variety of different tissues.

Most transgenic organisms are generated in the laboratory for research purposes. Others have been developed for commercial purposes  such as golden rice that has been modified to produce beta-carotene, the precursor to vitamin A.

You are examining a rigid plant tissue; it does not flex or bend. Tests show that it is not consuming oxygen gas, as would be ex
siniylev [52]

Answer & Explanation:

The examined tissue could be cortex, due to the fact that it's rigid and does not require oxygen, so metabolic processes, like respiration, are not happening.

If a swimmer cuts his foot on a seashell while wading in the ocean and bleeds into the seawater, his erythrocytes will shrink. W
Tom [10]

Answer:A) The ocean is hypertonic to the erythrocytes.

Explanation:cells shrink when placed in an hypertonic solution.

This shrinkage occurs does to the movement of water out of the cell and through the cell membrane.this phenomenon is called plasmolysis.

The movement of water out of this cell occurs through osmosis.osmosis is the movement of water from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.

In this case,sea water has a higher concentration of solute (hypertonic) and the blood cells has a lower concentration(hypotonic) .the cell membrane serves as the semi-permeable membrane and and a result water moves out of the cell
