Answer:
primary succession
Explanation:
you would start to see bacteria, fungi and lichens grow as the pioneer species.
Answer:
a mature haploid male or female germ cell which is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
Explanation:
Answer:
a. two plant species flowering at different times.
Explanation:
<em>The only option that is not a post-zygotic reproductive isolation mechanism would be option a, when two plant species flower at different times.</em>
Post-zygotic reproductive isolation mechanisms are those mechanisms that act to ensure that the product of fertilization remains invalid. This is as opposed to pre-zygotic isolation mechanisms that act to prevent fertilization and hence, formation of zygotes.
In option b, c, d and e; the zygote has been formed already and all the forces are just acting to ensure that it remains invalid. whereas in option a, there is no fertilization yet.
<u>Two plant species flowering at different times will ensure that there is no cross pollination between the two species. Without pollination, there cannot be a zygote formation.</u>
Hence, the correct option is a.
Answer: See explanation
Explanation:
1. The factors that should be considered when evaluating the costs and benefits of a new innovative process include the cost to build, the effort and time to implement and the maintenance and recurring costs. Therefore, the correct options is D. I, II and III.
2. The factors that will contribute to a measurement of environmental quality is the Salinity levels. Therefore, the correct option is C.
3. If all the other costs and benefits are equal, then the product that will be recommended will be option A "Product 1 because it requires less monitoring, reducing the overall cost"
Since Product 1 requires monitoring once in three months while Product 2 requires monitoring once every week, then we can deduce that product 2 will increase the overall cost.
4. The option that describes the relationship between human population size and resource use is option A "Countries with high populations are likely to use more resources".
When there's an increase in population, the people will make use of more resources when compared to an area with lesser population. Therefore, the correct option is A
Answer:
temperature
Explanation:
color doesn't affect the substance
light may have little affect but not much
shape doesn't affect the how quickly it changes
therefore temperature
