<span>Arrange the following five events in an order that explains the mass flow of materials in the phloem.
1. Water diffuses into the sieve tubes.
2. Leaf cells produce sugar by photosynthesis.
3. Solutes are actively transported into sieve tubes.
4. Sugar is transported from cell to cell in the leaf.
5. Sugar moves down the stem.

C) 2, 4, 3, 1, 5
Answer:
Zika virus and West Nile virus are the two pathogens which causes more diseases due to increase the population of mosquito.
Explanation:
Zika virus belongs to the family of Flaviviridae. Aedes mosquitoes which are active at day time are the carrier of this virus. West Nile virus is also spread through the bite of mosquito. The infected mosquito is the main cause of spreading of this disease. This virus is spreading too fast in the United States of America in the summer season where the population of mosquitoes increases.
<h2>Ecological Footprint - Option C</h2>
An ecological footprint is determined by measuring the rate of water used. The Ecological Footprint is determined by following how much biologically prolific field it needs to consume a population's carbon dioxide radiations and to produce all the means it absorbs.
A country's consumption is measured by summing imports to and deducting exports from its nationwide generation.
Answer:
The correct answer is D) requires phosphorylase activity.
Explanation:
Signals transmitted with the use of phosphorylation requires the presence and activity of an enzyme phosphorylase (also called Kinase) that can add phosphorus groups to proteins or other molecules in order for them to become messengers in the signaling pathway.
One example: The improvement in science and technology over the years has decreased the infant mortality rate. Since more babies live, we have a higher population.
Also, with increases in science and technology, there are many diseases that were once considered fatal that are now easily treated. This has also led to a higher population.
