Answer:
If the rock was found near a lava zone, it was igneous.
If he found it deep down where a lot of pressure is, it is metamorphic.
If he found it in riverbeds or where sand is, it is sedimentary.
Explanation:
Answer:
Gene flow would decrease as a result of the alteration of migration patterns. Therefore, the variability of this species would decrease.
Explanation:
Gene flow refers to the<u> transfer or introduction of genes from one population to another</u>. Gene flow enables the introduction of new alleles, therefore increasing biodiversity.
The rate of gene flow between groups of species depends on different factors. For instance, gene flow increases with the ability of a species to move from one place to another and, at the same time, on the possibility of migrating species mating with resident species. This occurs not only with birds but even with humans, when they migrate from one country to another, which increases diversity and variability.
Therefore, <u>if the migration patterns of birds that pollinate a plant species from South America is altered, then there would be less variability within this plant and also with this bird species.</u>
Answer:
Food prevention is to stop or slow down the spoilage of food,
loss of quality and edibility of food for longer time.
METHODS OF FOOD PRESERVATION
- CANNING: this involves cooking the food in special oil or paste and packing it in air tight cans under strict hygiene.
- REFRIGERATION: this involves storing the food at a temperature below 0°c. This renders bacteria and other decay causing agents inactive

when the fetus is exposed to a teratogen during the embryonic period is delay in growth
<h3>
What are some teratogens that affect the fetus?</h3>
Teratogens are any agents that cause an abnormality in a foetus after exposure during pregnancy. Teratogens are typically discovered following an increase in the prevalence of a specific birth defect. In the early 1960s, for example, thalidomide was used to treat morning sickness. The early exposure of the foetus resulted in cases of phocomelia, a congenital malformation in which the hands and feet are attached to abbreviated arms and legs.
Teratogens can also be found in the home or at work. The effect is dependent on the type of agent, dose, duration, and time of exposure. The first half of a pregnancy is the most hazardous. Infectious agents (rubella, cytomegalovirus, varicella, herpes simplex, toxoplasma, syphilis, and others) .
