Explanation:
Human health ultimately depends upon ecosystem products and services (such as availability of fresh water, food and fuel sources) which are requisite for good human health and productive livelihoods. Significant direct human health impacts can occur if ecosystem services are no longer adequate to meet social needs.
Answer:
C-14 from fossil had reached itshalf life
Explanation:
For radiactive isotopes (such as Carbon-14), per definition; the semi life or semi disintegration period; is defined as the time for which a certain mass isotope mass disintegrates to half of the atoms that make it up
For Carbon-14, this semi life period is 5730 years , and for the above example, as it is mentioned that we originally had 254 grams of C-14 but we currently have 127 grams (this is, exaclt half of the original mass of 254 grams), this leads us that 5730 years have passed since the original mass and the final mass (that is, one semi life period of C-14)
As you get closer to the equator the warmer it gets... I would say dry climate... because it seems like the closest thing to a warmer climate
Gymnosperms lack fruits so angiosperms are more advanced than them.
Compared to gymnosperms, flowering plants may thrive in a wider range of settings. Compared to gymnosperms, flowering plants mature more quickly and generate more seeds. Additionally, angiosperms have more complex and specialized woody tissues. Gymnosperms lack flowers and fruits and have unenclosed or coverless seeds on the surface of scales or leaves, in contrast to angiosperms, generally known as flowering plants, which have seeds that are contained within an ovary (typically a fruit).
