Answer: 100N
Explanation: Given parameters:
Mass of the bowling ball = 20kg
Acceleration = 5m/s²
Unknown:
Amount of force applied = ?
Solution:
To solve this problem, we apply newton's second law of motion.
Force = mass x acceleration
Now insert the parameters and solve;
Force = 20 x 5 = 100N
The advantage of growing genetically engineered BT crops are increased crop yields, reduced pesticide use, less environmental damage, less fungal contamination and reduced labor.
Explanation:
Bt is a soil bacterium whose genome contains genes for several proteins toxic to insects. When it is sprayed on the surface of crops, Bt toxins breakdown quickly when exposed to ultraviolet light, and also wash them in a strong rain.
They offers environmental and economic benefits to farmers with increased crop yields, reduced pesticide use, less environmental damage, less fundamental contamination, and reduced labor.
Thus the advantages of growing genetically engineered Bt crops over spraying Bt on the crops include lower production cost,less pest problems, and better yields.
<span>Pollen Grains is also known as male gametophytes of a flowering plant. They represent the male portion in the reproductive process. Pollen grains are tiny bodies which get transported through wind, insect or other natural agents, joins with the female parts of the flower through the process of fertilisation, resulting in the formation of seeds.</span>
The answer is sponges.
Animals with the radial symmetry of the body have<span> body parts that seem to extend from a central point, just like spokes in a bicycle wheel.
Through the process of elimination:
Sponges have radial symmetry.
Flatworms have bilateral symmetry.
Crayfish have bilateral symmetry.
Therefore, among all choices, only sponges have </span>body parts that seem to extend from a central point, just like spokes in a bicycle wheel. <span>
