First we can look at the taxonomic order:
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
The largest level would be the one closest to the top of the list because it is the least specific and therefore the most inclusive. Out of the choices given, phylum is closest to the top, so that is the answer.
Answer:
Population density is the option I would choose.
<span>The texture of the rock is a great example of the environment for igneous rocks. Many rocks of this type tend to have very jagged or rough textures, and are shown to come from environments that are high in heat, pressure, and also change greatly over short periods of time due to the many eruptions and lava flows that take place.</span>
Answer:
Half-Life is the time for a substance (U-235 in this case) to decay to 1/2 its original mass.
Since the problem is asking for the time for U-235 to decay to 1/2 its original mass (100 grams to 50 grams) then the decay time is 1 half-life, or 700 million years.
hope it helps u kindly mark as brainliest...
The abiotic factors in salt marshes include:
1. High, variable salinity
2. Low oxygen levels
3. Turbidity
4. Varying temperature
5. Sulphide toxicity
Salt marshes occur in zones between low and high tides. Salt marshes are periodically flooded by tides , so the plants living there have had to adapt to being submerged in salt water.
Only a limited number of plant and animal species can tolerate the harsh conditions of salt marshes and therefore salt marshes are generally poor in species.
