Hello! I have a question and I ask if you can make it a bit detailed. I am struggling to understand the Calvin Cycle in the proc
igomit [66]

Absolutely!  The Calvin Cycle is a process that takes place within the stroma of chloroplasts during photosynthesis.  This cycle is a light-independent reaction because it does not need sunlight to fully develop.  The process is, however, dependent on ATP and NADHP from those light reactions.

If you want a really good study guide for the Calvin Cycle, just follow this link; it helps A LOT!

A man travelling in a train threw an empty packet of food on the platfrom. Do you think this is a proper waste disposal method?
Anit [1.1K]

Answer:

No it is not a proper waste disposal method

Explanation:

A man travelling in a train and throwing an empty packet off food on the platform and not inside the waste basket provided is definitely not a proper waste disposal. the best waste disposal method he would have used was throwing the waste in a waste bin

waste water management is the process of managing waste water emanating from homes or industries and controlling the negative impact this waste water would have on the environment. and one way to do that  is the proper treatment of the water which entails removing contaminants from the waste water and converting the waste water into a useful effluent that can be used again ,

What index provides evidence of when different types of life evolved on Earth?
aev [14]

There are all sorts of ways to reconstruct the history of life on Earth. Pinning down when specific events occurred is often tricky, though. For this, biologists depend mainly on dating the rocks in which fossils are found, and by looking at the “molecular clocks” in the DNA of living organisms.

There are problems with each of these methods. The fossil record is like a movie with most of the frames cut out. Because it is so incomplete, it can be difficult to establish exactly when particular evolutionary changes happened.

Modern genetics allows scientists to measure how different species are from each other at a molecular level, and thus to estimate how much time has passed since a single lineage split into different species. Confounding factors rack up for species that are very distantly related, making the earlier dates more uncertain.

These difficulties mean that the dates in the timeline should be taken as approximate. As a general rule, they become more uncertain the further back along the geological timescale we look. Dates that are very uncertain are marked with a question mark.
