In order to improve the graph and make it more detailed in order to get a better perception why the honey bee populations are decreasing, there's few things that can be added.
- Number of bee keepers over the period
The number of the honey bee colonies is directly connected as to how many bee keepers there are. If there's a trend of a decline in the bee keepers, than there will be a trend in the decline of the honey bees.
- Area of trees suitable for the honey bees
The trees are crucial for the honey bees to be able to produce honey, thus it is very important that they have a certain area of trees on which they can feed upon. If there's a decline in the number of trees for the bees, than the bees will be dying from starvation.
- Pollution
The honey bees are animals that are very sensitive to changes in the environment, especially when it comes to pollution. If the levels of pollution are increasing in areas where there's honey bees, it will certainly affect their numbers in a negative manner.

The chloroplasts had inner membrane
Explanation:
The primitive photoautotrophs utilized hydrogen sulphide as the electron donor to perform photosynthesis for energy production.
Later upon understanding the endosymbiotic relationship of cyanobacteria which resided in the mitochondria of a eukaryotic host cell, the use of chloroplasts for photosynthesis was understood.
Generations after generations led to the development of chloroplasts by the cyanobacteria due to this symbiotic relationships which developed into the chloroplasts.
The unique presence of the inner membrane and its components like the stroma, thyllakoids helped the organism to utilize water as the electron donor for photosynthesis like the present day eukaryotes. This is the main reason why cyanobacteria is considered as the ancestor for eukaryotes.
A constant stream of charged particles flowing away form the sun
Answer:
True
Explanation:
When the resting potential of the membrane is changed, the membrane becomes either more negative inside or less negative. This small deviation from the resting potential is called graded potential. A graded potential occurs when a stimulus triggers opening or closing of the mechanically gated or ligand-gated channels present in the plasma membrane.
For example, the presynaptic neuron releases neurotransmitters in response to a nerve impulse. The neurotransmitter binds to receptors present in the plasma membrane of the postsynaptic neuron and triggers the opening of the ion channels to allow the inflow of particular ions to flow. The flow of ions changes the voltage across the membrane. This change in membrane voltage is a postsynaptic potential and is a type of graded potential.
