Organs because many tissues group and work together to form organs
Answer:
True
Explanation:
For example, NaCl - sodium chloride, when dissolved in water forms Na+ and Cl- ions.
Answer: Bacterial cells can be genetically modified so that they have the gene for producing human insulin. As these modified bacteria grow, they produce human insulin.
Explanation:
Answer:
Objective Lens Magnification = ×100
Explanation:
In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.
In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.
Total Magnification = (eyepiece lens magnification) × (objective lens magnification)
1000 = 10 × obejcetive lens magnification
Dividing both sides by 10
Objective lens magnification = 1000 ÷ 10 = 10
∴ Objective lens magnification = ×100
Simulations generally involve a simple design. In contrast, the world is a very complex system. Many events, such as how we farm, can disrupt the world's delicate balance. Simulations do not take into account the varied interactions that affect events in the real world.
