Answer:
The offsprings could inherit damaged DNA from the parents.
Explanation:
The hazardous chemicals may cause mutations to the DNA.
Answer:
1. The correct answer would be A) allow you to view living cells, while electron microscopes do not.
There are many advantages of light microscope over electron microscope such as:
- It is easy to use as compared to the electron microscope.
- It enables us to view both alive as well as dead specimen whereas electron microscope can be used to view dead specimen only.
- Light microscopes are much cheaper and have much lower maintenance cost as compared to the electron microscope.
2. The correct answer would be C) scanning electron microscope
Scanning electron microscope or SEM is a type of electron microscope which is used to observe surface topography and composition of the specimen. It can achieve resolution of up to 1 nanometer.
3. The correct answer would be 400x
The total magnification of the microscope can be calculated by multiplying the powers of the objective lens and that of the eye lens.
Thus, the magnification of the specimen would be 40*10 = 400x.
Answer:
Explain how heat in the atmosphere and water affect weather?
Amount of water in the atmosphere determines the amount of rainfall which depicts how cool the environment would look like.
Water has a great effect on the weather as evaporation helps to determine whether there would be heat or not, when there is high rise of evaporation it shows that the environment or weather is hot vice versa
Explanation:
Answer:
Dogs smell a lot better than humans, because they have more complex nose structures that allow them to follow any scent
An 1815 volcanic eruption in Indonesia was followed by a three-year famine around the world. This was due to:
a.The eruption's ash and gas significantly dimmed the sun.
The volcanic ash and gases like the sulphur dioxde remained suspended in the atmosphere for years. This reduced the availability of sunlight and hindered the process of photosynthesis that the crops perform for their growth. This lead to the death of farm crops causing a global shortage of food production (famines).
e.The eruption contributed to global warming.
The volcanic gases like CO, CO2 and CH4 caused the warming up of earth in the later years. This changed the weather patterns in various parts of the planet leading to drought, floods and cyclones. Such drastic climatic changes harm the crops and lead to their shortage.
