It would be Interphase, Prophase, Metaphase, and Anaphase
hello there
the answer is
If all the decomposers in an ecosystem were destroyed then the ecosystem would all apart.
This is because they give the nutrientsback to the soil in order for new organisms to grow.
thank you
A gardener accidentally trims the leaves of a green plant too short the leaves are now much smaller. He notices that the plant grows more slowly than it used to the plant has less chlorophyll to produce energy.
<h3>What about
chlorophyll in plant?</h3>
- Light is essential for any plant so as chlorophyll.
- They allow plants to convert light energy into sugars.
- It appears that a correlation links productivity and chlorophyll under special conditions.
- The more chlorophyll there is, the more electron transfer is ensured, the more photosynthesis is amplified and the more oxygen and glucose are produced.
- The amount of Chlorophyll contained in the leaves provides information on the health of the plant, its vigor and ensures that its Nitrogen requirements are met.
- The trace elements necessary for the plant are drawn by the roots in the soil.
- Chlorophyll plays a crucial part in photosynthesis.
- Chlorophyll, a green pigment found in plants' chloroplasts, is required for plants to use sunlight to transform carbon dioxide and water into oxygen and glucose.

Answer:
An effective vaccine was developed
Explanation:
(I actually learnt about this is history!)
Smallpox was around 75-100 years before 1977, and people continued to die from it especially when there were severe outbreaks (thousands of people lost their lives). The main technique for vaccination was to make a small cut in the patients arm or wrist, and then to rub a smallpox scab into the open wound (inoculation). However this was not as effective as it sometimes, brought infections into the wound, but the success rate was still pretty high.
Edward Jenner was convinced that there could be a more effective way of vaccinating people against the smallpox. Jenner discovered (from a milk maid!), that those that have been infected with cowpox won't catch small pox, as they are from the same family. Instead of small pox being the vaccine, Jenner used weakened cowpox pus instead. This was much effective as the side effect of having cowpox mild, and the patient made a full recovery.
Jenner put this cowpox vaccine in injections so that an open wound is not needed.
By the 1850's the vaccine was made compulsory, but many were against it: still believing that miasma (foul air) was the cause of the small pox. It was made compulsory or face a fine in the mid 1950's, hence small pox was eradicated by 1977
Hope this helps!
