Soil is important because it distributes plant species and provides a habitat for a vast range of organisms.
And, we protect it because it provides food, water, filters air and decomposes biological waste into nutrients for a new plant life.
Soil erosion is wears off a field's topsoil by natural physics of water.
I'm guessing but it seems that splitting would use the most energy. Don't take this as a correct answer!
Answer: Male red-winkled black birds defending limited nesting sites from other males.
Explanation: Intraspecific competition is defined as a competition between two individuals from the same species. There are two types of intraspecific competition which are interference intraspecific competition and exploitation intraspecific competition. For the purpose of the answer provided above, interference intraspecific competition is discussed.
In interference intraspecific competition, the species establish hierarchies through aggressive behavior in which one or more individuals within the population holds a dominant status over the others. These individuals limit or prevent access of more subordinate individuals to a resources through direct interactions.
Here, only those individuals who are dominant or holds territories will increase their production success. Example of this is in when two winkled black birds establishes a territory of nesting sites, thus limits the access of this nesting sites thereby defending the nesting sites from other males.
Answer:
Codominance
Explanation:
So this would either be codominance or incomplete dominance. With incomplete dominance, you tend to get a whole other colour- for example crossing black and white chickens and getting a blue chicken. If you cross brown and white, and get a mix, it must be codominance because both traits are shown.
Answer:
Explanation:
In this article, the author wanted to explain about yellow fever, putting some data about this disease, alerts and how to identify it, its reactions. Yellow fever is an acute febrile infectious disease, caused by a virus transmitted by mosquito vectors. This disease has two sort of cycles: wild (when there is transmission in rural or forest) and urban.
The virus is transmitted by the bite of infected transmitting mosquitoes and there is no direct transmission from person to person.
Yellow fever has epidemiological importance because of its clinical severity and potential for spread in urban areas infested with the Aedes aegypti mosquito. The yellow fever mosquito can live in forests as well as in the urban environment, where the greatest proliferation of yellow fever occurs, as this mosquito can infect a larger number of people.
The main symptoms are: The initial symptoms of yellow fever are:
1. sudden onset of fever;
2. chills;
3. severe headache;
4. back pains;
5. body aches in general;
6. nausea and vomiting;
7. fatigue and weakness.
