Answer:
Ocean water moves in predictable ways along the ocean surface. Surface currents can flow for thousands of kilometers and can reach depths of hundreds of meters. These surface currents do not depend on weather; they remain unchanged even in large storms because they depend on factors that do not change.
Surface currents are created by three things:
global wind patterns
the rotation of the Earth
the shape of the ocean basins
Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.
Answer:
Genetic engineering is deliberate modification of genome to gain desired traits.
The main steps of genetic engineering:
Restriction enzymes are used to isolate the required gene leaving it with sticky ends. Sticky ends are a short section of unpaired bases A vector, which is usually a bacterial plasmid or a virus, is cut by the same restriction enzyme leaving it with corresponding sticky ends. The vector and the isolated gene are joined together by ligase enzyme. The vector inserts the gene into required cells. The genes are transferred to animal, plant or microorganism cells, during early development, which allows them to develop with the desired characteristics.
Answer:
No, the amoeba does not die, it simply transforms into the daughter cells.
Explanation:
The parent cell copies its genetic material and divides. This process is not going to kill the amoeba who went through it.
None of the bove. Soil erosion occurs due to deforestation, water, wind and tillage of the land farms. It is the removal of the top layer of the soil, and leads to poorer quality of soil, called a soil disruption. This can be avoided by using proper farming techniques and afforestation.
The surviving species evolve more rapidly
