An investigator wants to study the function of eukaryotic hormone receptors. she has identified the hormone receptors for estrogens and progesterone. she finds that each has a hormone-binding domain, a transcriptional activation domain, and a dna-binding domain. in a cell culture line, she first eliminates the genes for the endogenous estrogen and progesterone hormone receptors. she then introduces a chimeric receptor that contains the progesterone-binding domain fused to the transcriptional activation domain, and dna-binding domain from the estrogen receptor. indicate below whether estrogen and/or progesterone genes are transcribed (induced or not induced) under the given conditions.

ya the other dude is right

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
