Answer:
Due to absence of predators.
Explanation:
The populations of invasive species grow rapidly because of the absence of predators that can control its population as as result, it disrupt the whole ecosystem. Change of climatic conditions of the area where they live causes them to migrate from its original place to a new region where the invasive species have no predators to control its population but mostly humans are responsible for the introduction of invasive species. In most cases, the introduction of invasive species happen due to human activities.
Answer
Along with decreasing rainfall comes rising temperatures. By 2050 the U.S. could be as much as 5.7°F warmer, and extreme weather events, such as heatwaves and drought, could be more intense and occur more frequently. As temperatures warm, evaporation increases, further decreasing water in lakes, reservoirs, and rivers.
The answers are:
A. DNA replication in the nucleus of a cell
B. From one helix of DNA in a replication process, we get two: The DNA is a double helix and it consists of two strands of specifically connected amino-acids. When the time for replication comes, a set of enzymes unwind the two strands and leave them as a base for additional two strands attaching to them - the green line is an example of that. The free nucleotides - adenine, guanine, thymine and cytosine are left open and the enzyme called DNA-polymerase helps to produce a new strand on the template of the old parental one (one of the blue ones in the picture)
C. By the location on the smaller picture - replication takes place in the nucleus. And the most important hint are the letters A - adenine, G - guanine, T- thymine, and C-cytosine. A connects with T, and G connects with C.
Rooting Reflex is a baby's tendency, when touched on the cheek, to turn toward the touch, open the mouth, and search for the nipple. Other behaviors include; sucking reflex; when an object is placed in the baby's mouth, he will begin to suck on it; grasping reflex; when touched on the palm of the hand, a baby will wrap his fingers tightly around the stimulus; moro reflex; infant startle response; when alarmed the baby will fling his limbs outward, then retract them and hold them close to his body. and also Babinski reflex; when stroked on the bottom of the foot, a baby will spread its toes.
