Answer: Option A.
All of these.
Explanation:
Competitive exclusion state that or show that two organisms who compete for the same resource in the same habitat cannot occupy the same niche and cannot coexist because the stronger organism or superior one tend to outcompete the weaker organism thereby leading to the exclusion of the the weaker organisms. It is a principle in ecology also called Gause's law.
Answer:
The answer is letter D, The storms cause wind and waves that move the sand from one place to another.
Explanation:
Along the coastline of Florida are their <em>beaches and barrier islands. </em><u>These islands are very important for the survival of plants and animals. </u>However, whenever a hurricane or a storm hits the area, it causes a dramatic change in the shape of the place. This is, primarily, because the storm causes the forces of wind and waves to move the sand from one place to another.
The movement of these can be towards or away from the mainland. <em>The fast movement</em> <u>causes the sand in the area to be deposited away from the shore,</u> thus creating sandbars. <em>The slow movement</em> <u>causes the sand from the sandbars to return back to the shore.</u>
Diploid meaning 2. Is a cell/ organism that has paired chromosomes, one from each parent. Humans have 23 of these.
Answer:
If all the bacteria are removed from the earth, all the organisms are negatively affected.
Explanation: There are also some beneficial bacteria which helps in the nitrogen fixation called Nitrogen fixing bacteria such as Cyanobacteria and Azotobactor. These bacteria fixes atmospheric nitrogen into ammonium and nitrates form because plants are unable to use the atmospheric nitrogen, it only use nitrogen in ammonia and nitrates form. Plants absorb nitrates and form amino acid.
Answer:
This is due to the event of Speciation that happened for the rodents in Island B but not for the rodents in Island C.
Explanation:
- Due to splitting of the population,
- The sub-population of rodents formed in Island B are B1 and B2.
- The sub-population of rodents formed in Island C are C1 and C2.
- In case of Island B, each of the B1 and B2 sub-populations that got split from each other developed certain mutations that were necessary for them to adapt to the particular diverse environment each of them were exposed to, through the period of 50,000 years. These mutations were so varied that reproductive isolation was generated between them that resulted in each of them to develop into different species.Hence, speciation happens here and B1 and B2 are incapable of inter-breeding.
- In case of Island C, each of the C1 and C2 sub-populations that got split might have got exposed to similar environmental change or no environmental change or the environmental change might have been too small to cause drastic change in each of the sub-populations. As a result of this the two sub-populations might have acquired certain mutations to adapt to the environment each of them were exposed to, through a period of 100,000 years. These mutations might not have been too variable or contrasting to cause reproductive isolation between C1 and C2. Hence, no new speciation happens here and C1 and C2 are capable of inter-breeding.
