extra calcium
Explanation:
it binds to the vesicles in the terminal axon and induces exocytosis. If there is more calcium, more neurotransmitter will be released
III only (floods and drought) is an example of density-independent factor affecting population growth.
<h3>WHAT IS DENSITY-INDEPENDENT FACTOR?</h3>
Certain factors affect the growth and multiplication of living organisms in populations. These factors can either be;
- Density-dependent
- Density-independent
Density-independent factors are those factors that are not dependent on the density of the population to affect them. These factors are usually physical factors of the environment like;
- Disasters
- Flood and drought
- Earthquake etc.
Therefore, III only (floods and drought) is an example of density-independent factor affecting population growth.

Mitosis is only 1 division whereas meiosis is 2 divisions.
Answer:
naked seed, Conifers, pollen grains (male gametophyte)
Explanation:
Gymnosperms are known as seed producing plants. the term gymnosperm means is naked seed that means that the seed in gymnosperm plants are non-encased while in angiosperms seed are covered within an ovary.
Conifers is an example of gymnosperms plants. Other example of gymnosperms are cycads, gnetophytes and ginkgoes.
Gymnosperms are fertilised when pollen grains (male gametophyte) are carried by the wind to the open end of an ovule, which contains the eggs, or female gametophyte. The ovule formed is converted into naked seed.
Hene, the correct answer for blanks are naked seed, Conifers, pollen grains (male gametophyte).
It would be a pain to write all out all the details, so this might help. There isn't that much reading involved. http://lsa.colorado.edu/essence/texts/lungs.html
