'Which food did dinosaurs compete for?' would be impossible to test through observation. The last option.

<h3>What are observations?</h3>

Observation is a process of obtaining information about phenomena using any of the five senses. In other words, observations are a way of obtaining data for scientific purposes.

Why is the question about dinosaurs' food unanswerable by observations? This is basically because dinosaurs can no longer be observed in this our present world.

Dinosaurs are believed to have gone into extinction about 65 million years ago during the Cretaceous period. Thus, unless one can go back in time, there is no way to answer the question of which foods did dinosaurs compete for through observations.

A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-ge
Sophie [7]

Answer:

a. purple allele (C) = 0.609, pink allele (c) = 0.391

b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476

Explanation:

Given -

Purple flowers - 847

Pink flowers - 153

The frequency of recessive genotype i.e

q^ 2 = \frac{153}{1000} \\q^ 2 = 0.153\\

Frequency of recessive allele i.e q is equal to

q = \sqrt{0.153} \\q = 0.391

As per hardy Weinberg's first equilibrium equation -

p + q = 1\\p = 1-q\\p = 1-0.391\\p = 0.609

Frequency of purple homozygous species

= p^2\\= 0.609^2\\= 0.371

Number of purple homozygous species = 0.371 * 1000= 371

Number of pink homozygous species = 0.153 * 1000= 153

Heterozygous species is equal to

(1-0.371-0.153)* 1000\\= 0.476 * 1000\\= 476
