Answer:
to describe how proteins are produced
Explanation:
The main function of DNA is to carry information contained in its sequences, called genes. Genes are excerpts from the DNA present in chromosomes that initiate protein manufacturing processes with various functions in the body. For proteins to be formed, DNA has to "work". That is, DNA has to start the replication process in order for RNA transcription to be done, so that protein manufacture can finally be done. For this reason, we can conclude that if an author writes "Your DNA at Work", he probably wants to describe how proteins are produced.
Answer:
mutualism is the relationship they have
Of the annual global total of fixed nitrogen, human activities account for roughly 45%.
Nitrogen fixation is the global amount of nitrogen that gets assimilated by any living organism into another organic compound. The organic compound can be ammonia or nitrogen ions.
Of the total global annual nitrogen fixation, humans account for a great amount. The current estimation is that humans cause 45% of the nitrogen fixation annually. The leading causes of this high rate are the burning of fossil fuels and increased agricultural fertilizer use.

<h2>Water;NADP is the correct option</h2>
Explanation:
Z scheme also known as non cyclic electron flow which starts with the absorption of light by photosystem II
- Z scheme involves both photosystem(PS) I and photosystem(PS) II
- Water becomes oxidized and oxygen gas is released/evolved as a result NADP+ gets reduced and produces NADPH
- Oxidation of water and release of protons in lumen is done by PSII whereas reduction of NADP+ to NADPH is done by PSI
- Oxidation of water molecule establish gradient of proton and this gradient drives synthesis of ATP
Answer:
d. Actively transported into the phloem
Explanation: Source is the place where sugar are been produced and are active transported to actively growing part of plants that requires it. The actively growing plants part that requires sugar are called sink.
Photosynthate the end products of photosynthesis is what is been loaded into the phloem through active transport and then moved to sink i.e plant part that requires the sugar through a process called translocation. The sink in plant includes the fruits, leaves for some vegetables,flowers for ornamental crop,too or tuber, rhizomes.
When the phloem cell is damage there is reduction in transport of photosynthate or accumulation in a particular part of plant.
Actively growing parts of plant have a high demand for sugar or sucrose than the old and weak parts of plants.
