Teratogens are agents or factors that causes malformation of an embryo they include alcohol,cigar smoke, drugs, maternal stress and paternal age. At the embryonic period the unborn baby is at a very high risk of developing structural defects ddue to the effects of teratogens. Teratogens may lead to abnormal development in muscles, tendons and bones.
True- they should be because the closer to the equator you get going vertical the warmer it is so depending on the location and latitude it should be the same
This can be answered with the help of describing osmosis and diffusion in plants. The motion of molecules through the semi-permeable membrane is osmosis. In diffusion, motion of molecules is direct and does not need a semi-permeable membrane.
Explanation:
- In plants, osmosis help plants to absorb water from soil. Diffusion is the process by which carbon dioxide diffuses to the leaves and then to the cells.
- The genetic modifications in some of the plants can help in survive and adopt the osmosis in a very dry environment. They develop defense methods to handle the water loss. Some plants in a permanent dry environment like desert have special structures like reduced leaves, sunken stomata, and so on to conserve water.
- Osmosis happens only in liquid medium. Diffusion happens in any medium - solid, liquid, and gases.
