1) What evidence is there that the human species has been successful so far? Explain.
Successful evolutionarily means "surviving and spreading geographically". Since we are far from extinction and we've spread all over the world, we are successful as a species.
2) What environmental pressures in the past do you think were most important in shaping the human species as it exists today?Answer: I believe that the environmental pressures that exist now and that may be shaping the human species are the use of land, the extraction of resources, greenhouse emissions and water use. This are being used by use more and more as we start overpopulating the earth.
Answer:
Humanity is far from extinction we've spread to every corner of the earth. We have also learned to reproduce and make things to help us survive longer. We have also found ways to try and extinct ourselves but, that might be far from happening.
2: The environments, climate, and predators helped shape humans, they learned how to make weapons and create a shelter to survive harsh conditions in the wild.
3: Some of the environmental pressures we face now are man-made for example, pollution, a lack of land, and overpopulation. Some however are natural, like our limited supply of minerals.
4: I think most of the environmental pressure will come from pollution and a lack of space. With so many people around, there's going to be a lot of vehicle use, and things such as littering. We're going to have to change and start cleaning up after ourselves and limit the use of gas.
Answer:
Option (2).
Explanation:
Enzymes are made of proteins that have the specific amino acid sequences. Enzymes have well determined 3D shape and work in their specific shape and at specific physical and chemical condition.
Enzymes may acts as catalyst that can increase the rate of the bio chemical reaction. Each enzyme is specific for one reaction and lowers the activation energy of the reaction. Enzymes increases the effective collision between the substrate molecule and increases reaction rate.
Thus, the correct answer is option (2).

Answer:
El entrecruzamiento cromosómico es un proceso biológico que ocurre durante la meiosis, cuando las parejas de cromosomas homólogos, o del mismo tipo, están alineadas. Durante la meiosis los cromosomas emparejados están alineados en las llamadas placas meióticas, y tienen un mecanismo biológico que los mantiene unidos.
