Osmosis help plants to absorb water from soil. Diffusion is the process by which carbon dioxide from the stomata diffuses to the leaves and then to the cells.
Explanation:
- Example one - 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.
- Example two - Some plants in a permanent dry environment like desert have special structures like reduced leaves, sunken stomata, and so on to conserve water and thus achieves diffusion.
- Another example for diffusion - loss of water vapour from leaves to the atmosphere. Another example for osmosis - the roots of the plants have high concentration than the surrounding soil and hence water flows into the roots.
Answer: Polygenic means that most traits are controlled by an additive effect of two or more genes on a single phenotype.
Explanation: Polygenic inheritance or quantitative characters are those that vary in the population along a continuum. For example, height, skin color, etc.
Often, penetrance, pleiotropy, epistasis, expressivity and environmental factors are involved in producing a continuous distribution of phenotypes.
Traits such as height that show a continuous range of variation and do not behave in a single Mendelian fashion are known as quantitative or complex traits.
Answer:
Explanation:
Translation ends in a process that called ( termination) .
Termination happens when a stop codon in the mRNA (UAA , UAG , UGA ) enters the A site.
Stop codons are recognized by proteins called release factors,
which fit neatly into the P site (Though they aren't tRNAs ) .
Some energy sources are wind turbines, generation from air resistance
Answer:
Explanation:
Electromagnetic waves all travel at the speed of light when in vacuum, and essentially this same speed in normal air. Since wave speed is product of frequency and wavelength, c = f λ and λ = c/f = (3.00 x 108 m/s) / (7.5 x 1014 Hz) = 4.00 x 10-7 m = 400 x 10-9 m = 400 nm.
