Answer:
genes for flower color and edge shape are linked. They do not assort independently.
Explanation:
<u>Available data:</u>
- test cross between a purple-flowered pea plant having serrated leaves and a white-flowered pea plant having smooth edges.
- serrated leaves → dominant trait
- smooth edges → recessive trait
- purple color → dominant trait
- white color → recessive trait
- F1: 4 purple-serrated:1 purple-smooth:1 white-serrated:4 white-smooth.
There are two genes involved in the cross. The expected ratios are 1:1:1:1 because we assume genes assort independently. However, we see a different phenotypic distribution. When phenotypic ratios differ from the expected ones, it means that genes are linked.
To know if two genes are linked in the same chromosome, we must observe the progeny distribution. If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. But if instead of this distribution, we observe a different one, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent

the sentence does not make sense, it is an example of deletion mutation
The thyroid is an endocrine gland that regulates metabolic function through the production of all of the following hormones except: Thyroliberin.
Thyrotropin is a peptide secreted by the anterior pituitary gland that prompts the thyroid gland to release thyroxine. It is also known as thyroliberin and thyroid-stimulating hormone (TSH) Thyrotropin-releasing factor, a peptide located in the hypothalamus of the brain and affecting glandula thyroidea secretion, acts to cause the release of TSH.
In vivo, thyrotropin controls thyroid development favourably. The gland becomes hypoplastic in its absence, either as a result of a pituitary disorder or as a side effect of thyroid hormone therapy, with a reduction in the quantity and size of thyrocytes.

Well there would no longer need plants to make air or take Carbon Dioxide, and the Carbon Dioxide would me our main meal
