The organism generally must have hard parts such as shell, bone, teeth, or wood tissue; the remains must escape destruction after death; and the remains must be buried rapidly to stop decomposition. This does make the fossil record biased because animals with soft bodies are less likely to form fossils. It also means that particular environments will not help fossils form because the remains must be buried rapidly and escape the detection of scavengers.
4. Describe three different methods of fossilization.
Organisms can be buried and preserved in substances such as frozen soil, volcanic ash, sediment, ice, oil, and amber. This process preserves even the soft parts. Hard parts such as shells, teeth, bones, and wood can also be more easily preserved because they resist weathering. Hard parts can also become altered due to carbonization (leaves only a thin film of carbonaceous material), petrifaction (gets replaced by minerals in water turning it to stone), and replacement (hard parts dissolve and get replaced by calcite, silica, dolomite, and iron compounds)

In a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of the allele a is 0. 3. What i

zavuch27 [327]

Here, given-

homozygous alleles 'a' have a frequency of 0.3.

Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.

The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.

Calculation-

$p + q = 1\\0.3 + q= 1\\q= 1- 0.3\\\\q= 0.7$

Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-

$p^{2} + 2pq + q^{2} =1$

$p^{2} = dominant homozygous frequency\\2pq= heterozygous frequency\\q^{2} = recessive homozygous frequency\\$

Thus, the individuals homozygous for the allele can be calculated by $q^{2} = (0.7)^{2} \\= 0.49$

Fdsci 101 what general trend do you observe relative to the masses of these species? question 3 options: all species basically h

Alexandra [31]

The third and last option is correct.

Species in the past (referring to dinosaurs) were more massive.

$\bf~CO_{2}$ levels where higher in the past, which meant that plants prospered during that time since they had a easy access to food. That contributes to the fact that herbivores could grow bigger because there was more food. Which in turn, increases the size of early carnivores which eat bigger herbivores.
