This chart shows descriptions of the atoms for four different substances. A 2-column table with 4 row labeled Descriptions of Four Substances. The first row has entries Object 1, Object 2, Object 3, Object 4. The second row has entries slide past each other, are very viscous, form a crystal, spread out to fill their container. Which substance is a solid? Object 1 Object 2 Object 3 Object 4

answer; a male inherits only one allele of the x-linked gene controlling hair color;

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

c. is the correct answer
