An ecosystem becomes unstable when there is an unequal number or ratio of predators and preys. Predators are animals that consume smaller animals and other edible produces found within the environment, while preys are first consumers of the producers (i.e. plants) that are found around a particular area.
When there is a greater number of predator over prey, the result is a decrease in population of primary consumers and the environment will also follow by increasing its plant growth, and other processes. When there is a great number of prey over predator, producers will have a hard time to thrive providing less efficiency in producing supply for animals that are dependent for food, water, and shelter.
The Yellowstone National Park is a very good example of this predator-prey relationship. The re-introduction of the wolves made the ecosystem become balanced once again.
The correct option is B.
The signals which dogs gives when giving in to another dog is called submission signals. Submission actions of dogs include: lowering of the head, partial closure of the eyes, rolling on the back and exposing the belly, holding the tail low or tucking it between its legs. These signals tell the other dog that the dog exhibiting these action is submitting to it.
Answer:
C) 128
Explanation:
In binary fission each bacterial cell will divide into two parts.
1. Since the bacteria divides divides after every 20 min , We have to find the number of division in two hours two hour(2x60=120 min) which will be;
120÷20=6
It will undergo 6 divisions.
2. To calculate the number of bacteria at the end of 2 hours
Bacteria in the beginning x 2∧ Number of division
1× 2∧6= 128 Bacteria
2. Because the gravitational force from anything that small compared to a planet is so minuscule it's nearly impossible to feel or measure.
3. Because do not have life and other processes necessary to create the gasses and substances necessary to create an atmosphere.
4. If the amount of mass lost was large enough it would likely allow the moon to eventually orbit away
Answer:
Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. The enzyme will have been denatured . Enzymes therefore work best at a particular temperature. Proteins are chains of amino acids joined end to end.
