Answer:
1) They can kill Other Unintended Organisms
2) Some of the Pests might be Resistant to the Pesticide, Meaning the Pesticide no Longer Works on the Pests
3) They can Bioaccumulate in the Food Chain
Explanation:
1) Bugs need for the proper growth of plants are often killed by pesticides, often from wind blowing them onto other plants for the bugs
2) Its the same princincle as super bacteria, some bugs will likely survive the pesticide, often because of a mutation, and pass that on as it is advantageous
3) This is the most talked about issue when it comes to pesticides as it is largely blamed for endangering the eagle population in the US - with DDT in particular being pointed to
Answer:
Explanation:
Herbivores are able to come back easily when they are search for food because their are more than enough food for them to prey on while in lion population, their main feed also take longer period to be produced since they also feed on animal that take time to give birth such as zebras, so they go for other smaller organisms such as waterbucks which take them more time to be completely feeds on to gain required energy.
Answer:
Explanation: Tube 1 doesn't contain an organism so it can't be that one. Both a snail and a plant are considered an organism, and cellular respiration occurs in almost any organism's cells
Answer is at the very end
Explanation:
Given parameters:
Mass of the asteroid = 10 x 10⁹kg
Distance between the asteroid = 850km
Unknown:
Force = ?
Solution:
We can predict the outcome of this reduction in distance between the two masses using the newton's law of universal gravitation.
The law states that "the gravitational force of attraction between two masses is directly proportional to the product of their masses and inversely proportional to the square of the distances between them".
Mathematically, we have;
F =
F is the gravitational force
G is the universal gravitational constant = 6.67 x 10⁻¹¹Nm²kg⁻²
m is the mass of the body
r is the distance between them.
From this, we know that as the separation increases, the force of gravitation will reduce since the mass is constant.
The distance between the two asteroids decreased from 1000km to 850km, this will increase the force of attraction between them and we expect the force to be higher than 6700N.
At 1000Km, force = 6700N,
since as the distance reduces the force increases, we expect the force to be about 9200N.
Let us verify this by plugging the values into the equation:
F =
F = 9200N
This could be because star A is closer to Earth than star B is, making it appear brighter.
