1. The plant life that is characteristic of a biome depends upon:
eimsori [14]

Answer:

D. all of the above​

Explanation:

Biome refers to a large and relatively distinct terrestrial region having similar climatic conditions regardless of where it occurs on Earth. The characteristic climatic conditions (temperature and precipitation being the most important ones) and soil type of each biome type determine the type of plant species found there. Therefore, each biome is characterized by specific flora.  

For example, a desert biome is a temperate or tropical biome characterized by a lack of precipitation, seasonal variations in temperature and poor soil type with low organic matter that limits plant growth. Desert biomes have only the plant species that can survive these harsh conditions.

if the following graph represents the decay of strontium-90 in an igneous rock, what event occurred at 0 years on the horizontal
kodGreya [7K]

Answer:

At 0 years, an event took place which is known as metamorphosis of igneous rock i.e., formation of igneous rocks from melted magma.

Strontium-90 is a radioactive element which undergoes beta decay to form yttrium-90. It has a half life of approximately 28 years and decay energy of 0.546 MeV. This radioactivity is used by geologist to estimate the age of the rock, fossils, meteorites etc. Other radioactive elements used by the geologists are carbon-40, potassium-40 etc.

Radiometric clock is set when the rock was formed in the past i.e., the moment when an ingenious rock was solidified from molten magma.
