Invasive species cause harm to wildlife in many ways. When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. ... Invasive species can change the food web in an ecosystem by destroying or replacing native food sources.
hope this helps :)
DNA in the nucleus of eukaryotic cells is collected into a chromatin.
A chromatin is a complex of nucleic acids (DNA or RNA) and proteins called histones which condense to form a chromosome during cell division.
In eukaryotic cells, it is found within the cell nucleus while in prokaryotes, it is found inside the nucleoid .
Its functions are;
1. to package DNA into a smaller volume to fit in the cell.
2. strengthen the DNA to allow mitosis and meiosis.
3. acts as a mechanism to control expression
The chromatin is easily recognized through staining. Its name literally means "colored material."
Answer 1) : Change in direction.
Explanation : When an airplane starts to turn from south to west at constant speed gets accelerated due to change in direction. The change in direction of the airplane causes the airplane to accelerate in the direction of west while it was moving in south. Here the acceleration is being affected because of the change in direction of the object moving with a constant speed.
Answer 2) Change in direction and increasing speed.
Explanation : When a biker was riding at the speed of 5 m/s north and then changed the direction to west at an increased speed of 7 m/s this was due to increased speed and change in the direction of the bike.
There was two factors which contributed to change the acceleration in this case. It was because of change in speed of the bike and also because of change in direction. This kept the bike in acceleration by increasing the speed while changing the direction.
Answer 3) Increasing speed.
Explanation : While the shopping cart was observed to speed up on the runaway while it goes down a hill gets accelerated due to change in its speed.
In this case, when the shopping cart is been released from the upside runaway; as it goes down it gains more speed due to the slope of the runaway. This is because the acceleration is increasing because there is increase in the speed of the shopping cart.
The electrolytes present in our body should be in the right concentration. This is said to be electrolyte balance.
Why does an electrolyte imbalance occur?
Electrolyte imbalance is caused when the body fluids are present in large amount. When we sweat or vomit more, it can be due to the lower level of some electrolytes. So, it is necessary that the electrolytes should be in proper proportion.
Electrolytes plays a very important role in our body. It helps in regulation of fluids present in blood and blood plasma, normalizes the pH of blood, allows the contraction of muscles and so on. For all these necessary roles to occur, our electrolytes should be in proper concentration. This is called electrolyte balance.

The largest population that an environment can support is called its carrying capacity.
Determining the carrying capacities for most organisms is fairly straightforward. For humans carrying capacity is much more complicated. The definition is expanded to include not degrading our cultural and social environments and not harming the physical environment in ways that would adversely affect future generations.
For populations which grow exponentially, growth starts out slowly, enters a rapid growth phase and then levels off when the carrying capacity for that species has been reached.
