Answer:
Indeed, both monogamy and polygamy are reproductive strategies adopted by the different species of the animal world.
Explanation:
Polygamy implies the adoption of a unique and stable partner by an individual, with which in principle it will reproduce. Different species, including humans or penguins, in addition to maintaining the same pair for reproductive purposes, generate bonds of coexistence.
Other species (in fact, most animal species) are not guided by this type of relationship, but fulfill their reproductive functions in a random way, that is, with several individuals of the same species in a random way, which is called polygamy. In this case, there is a constant change in the reproductive couple, which responds to multiple factors such as for example a gender disproportion within the species (for example, many females and few males would make those few males have to comply reproductive functions with several females during the mating period), or due to the non-sedentary nature of life of these species.
Answer:
elliptical (nearly circular)
Explanation:
According to Kepler's laws of planetary motion, the planets do not revolve around the Sun in exact circular orbits. The path of the planet or any other body in the solar system is elliptical, with the Sun at one of the foci. Though, the eccentricity is not large, so one can say, the path of the planets and the asteroids around the Sun is nearly circular.
Answer:
Yes, I think the benefits of using water resources to generate electricity outweigh the costs and drawbacks
<u>Explanation:</u>
The electricity produced using water is called hydropower has benefits like it does not pollute the air. If water is used to produce electricity than every state can produce its own electricity without relying on other states for fuel.
With these benefits, hydropower is very costly and it has several other drawbacks also like it pollutes water and reduces the oxygen level in the water. So it is a threat to wildlife. It reduces recreational activities like swimming, boating, and fishing, etc.
Answer:
The solution with the higher concentration of solutes (a.k.a liquids/water)
Answer:
It is difficult to tell if fluoride causes this cancer.
Explanation:
The U.S. public health service has diverse team with more than 6500 employees. Their mission is to promote health and safety of the people of United States. The fluoride is added to drinking water since 1940s and this process is called water fluoridation. It is difficult to tell if the fluoride causes cancer but there has not been any relationship found between fluoridated water and cancer. Fluoridated water can reduce and reverse the tooth decay.
