Answer:
<em>A line graph</em>
Explanation:
A line graph would be the best type of graph to show changes over time. A line graph constitutes of a y-axis and an X- axis. The presence of the axis will make is easier to look at the height changes which occur over time. The y-axis of such a graph could show the height, the X axis of such a graph could show the time. Hence, a line graph could be the best one to represent such a change.
Answer:
Think of decomposers as an ecosystem's maintenance crew. Without decomposers, dead animal carcasses would pile up, and the soil would lack nutrients plants need to grow– the entire ecosystem would break down without this vital component of the food chain.
if you need help on the other answer don't hesitate to ask!
Upwelling is a process in which cold water from depths arise to the surface,
it's important because :
- It bring a lot of nutrients to the surface of the ocean
- It maintain the temperature of the ocean
hope this helps
Answer: Winds are primary energy source for currents that flow horizontally in the ocean surface layers (less than 100 to 200 m deep). Hence surface currents often called “wind driven currents” or “wind drift currents”.
Currents that flow deep in the oceans below the level affected by winds are generated by convection caused by variations in water density. Higher-density waters sink and displace (push aside or up) less –dense water. Because density is determined by temperature and salinity, deep-water circulation is called “thermohaline circulation”.
The winds are the primary source for both ‘wind driven circulation’ and ‘thermohaline circulation’ is the sun. Winds are generated by the density variations in the earth’s atmosphere caused by solar heating and radiative and evaporative cooling.
Thermohaline circulation is driven by density difference between ocean water masses caused by temperature and salinity variations.
Explanation:
This is the main cause to form a wave over the sea surface.
Answer:
C) Non-protein-coding DNA that is transcribed into several kinds of small RNAs with biological function.
Explanation:
The genome of humans consists of a variety of protein-coding and non-protein coding sequences. The protein-coding sequences are the sequences which can get translated into the protein sequences.
When the genome was sequenced, it was expected that the size of these coding sequences will be larger but the sequences came to be smaller. This shows that the rest of the genome is made of the non-coding sequences.
The importance of these non-coding sequences is that they do not form the proteins but they can undergo transcription and form the variety of RNA molecules like the regulatory RNA, the ribosomal RNA and others.
Thus, Option-C is the correct answer.
