Answer:
Pesticides are selected based on the target species, growth stage, and enviromental conditions prevalent in a region.
Explanation:
Knowing environmental conditions in a region when using a pesticide could prevent health risks to every type of living beings that abide there. Occupational exposure and pesticide residues in food and drinking water could be risky due to pesticide toxicity, the weather conditions, the adsorption on soil, among others.
Answer:
Explanation
In medicine, genetic engineering has been used to mass-produce insulin, human growth hormones, follistim (for treating infertility), human albumin, monoclonal antibodies, antihemophilic factors, vaccines, and many other drugs. In research, organisms are genetically engineered to discover the functions of certain genes.
Explanation:
The common cold, also called viral rhinitis, is one of the most common infectious diseases in humans.
Answer:
CLOSED.
Explanation:
Stomata are found in epidermal layers in green aerial parts of plants, especially leaves. They occur mainly on the lower surface of dicotyledonous leaves, although on monocotyledonous, they are found on both surfaces. Intercellular air spaces found throughout the leaf are linked to stomata.
Stomata permits plant uptake of carbon dioxide, which is a necessity for photosynthetic processes. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.
Therefore, it can be said that Stomata adjust temperature, staying closed when temperatures are hot and dry.
