Half life is the period of time it takes for one-half of the atoms of an original isotope to decay.
In this example we have: where n= the number of half lives.
Thus:
From this equation n=3. The answer to your question is: 3 half lives have passed which gives the meteorite an age of 4.5*3= 13.5 billion years.
The respiratory system brings oxygen to cells in the body. And it removes waste, carbon dioxide. The Excretory system removes wast as well from the digestive system and from blood out of the body.
The answer should be the 3rd one

The population of moose will still be around 850 in 30 years.
<h3>What is carring capacity?</h3>
Carrying capacity is the number of individuals that an environment can support without significant negative impacts to the organism and its environment.
With that being said, the moose population size will be same or still 850 after 30 years. Rate of plant growth on isle Royale supported in equilibrium moose population of 850 moose and if there will more 200 mooses arrived then there will be no sufficient plants available to feed those additional mooses. This is the concept of carrying capacity. Carrying capacity is defined as the species average population size in particular habitat. Species population size is restricted by environmental factor like food, shelter, etc. If number of mooses will be increased in particular habitat and plants are limited ,then there will be strong competition between them, which results in survival of the fittest.
So when population size increases on Isle Royale,may be in beginning, for a while there will be sufficient plants to feed those additional 200 mooses, but after some time plant population will reduce and there will be not enough plants to feed all of the mooses. And if needs are not met, population will decreases which allows plants to grow in normal population to feed 850 mooses. So, after 30 years moose population size would be around 850 mooses.
