Answer: Waves are defined as energy transferred from one place to another. The way in which the energy travels is called the medium. These waves can be in the form vibrations through light or matter, such as solid, liquid, or gas (e.g. sound waves or earthquakes). The most important terms in relation to these waves are wavelength, frequency and amplitude.
Wavelength is directly related to frequency because it describes the displacement between the waves, whereas frequency describes how many waves pass within a second. Larger wavelengths are associated with lower frequencies, and smaller wavelengths are associated with higher frequencies.

One structure that can be found is most plant cells is chloroplast. A plant cell may have around 0 to 20 chloroplast, depending on their location in plant or their function.
Chloroplast is the structure that photosynthesis occurs. Photosynthesis is the method that plant make food for themselves. They turn sunlight into food such as starch.
Plants are autotrophs, which means they make food themselves, they don't need food from other sources like animals. Therefore, chloroplast is not found in animal cells because we are heterotrophs, we feed on other food.
The difference between past time focus and present time focus is that present time focus refers to the moment we are living in, the moment we are going to now. The past focus is that we are paying attention to the things that we have experienced in the past. The basic difference is one things is about being focused on the present situation while the other is thinking about past situations or experiences.
Explanation:
Past time focus : David has good marks and he is thinking about that achievement and good grades at that time
Present time focus : David has gotten good grades right now so he is going to put in time to better himself.
