They young populations are challenging and expensive for a country to care for because they require more healthcare, immunization, and checks-up , Especially for children. Not only that, they also still haven't be able to contribute to the country's economic growth
Answer:
The true statement is option D. The two major factors determining the Earth's temperature are the Earth-Sun distance and the concentration of oxygen in the atmosphere.
Explanation:
The distance between the sun and the Earth is one of the factors that determines the temperature of the planet. The energy from the sun travels to the Earth, increasing the temperature.
The other fact that has a role in the Earth's temperature is the concentration of oxygen in the atmosphere. It can increase or decrease the temperature according to the amount of this. Oxigen contributes to the greenhouse effect, which helps to keep the temperature in a range that allows life to happen.
Explanation:
Animal indicator list is a barometer to check how a particular ecosystem is affecting the lives of particular animals. The indicator measures stress or behavior in the ecosystem to know whether to protect the specie or allow them undisturbed
This is to avoid or reduce to barest minimum incidences of extinction of such specie in the ecosystem.
The grizzly sudden reduction in number from well over 100,000 in California to less than nothing in 1942 triggered the need to protect the grizzlies from human destruction and possible extinction. Grizzlies was a national specie and appeared in the flag of California. The population gradually reduced in most of the states of Idaho, Utah, Alaska and many more.
The grizzlies in 1975 were declared protected species to avoid being hunted or trapped by humans and to repopulate them in the areas where they once lived. Their future will depend largely on humans ability to allow them to coexist with them, by setting out a large area for them to live and regroup.
This will go to balance the ecosystem which has been tampered or disturbed by development.
Answer:
strong, long duration winds in a large fetch weak
Explanation:
A fetch is an area of the ocean or sea where wind blows in a fixed direction, this consistent wind leads to waves.
Fetch length is the distance reached by the wave generating winds when measured in from a horizontal direction. The wind creates wave by forming a drag and a frictional drag, the wind the flow over the wave making it grow. Therefore, a strong, long duration winds in a moderate fetch or weak fetch will produce largest waves.
Answer:
Marble is a metamorphic rock. Marble is a metamorphic rock, that forms when limestone (another rock) reaches a certain pressure and heat
