Answer:

up-regulation

Explanation:

Upregulation is where a increases the quantity of a cellular component like protein or RNA in response to an external stimulus.By controlling the number of its receptors, cells may increase and decrease their cell sensitivity.... Hormones can also trigger cells to control themselves by upregulation.( Estrogen is the primary sex hormone for females).

Plants were grown in two different conditions. The plants on the left were grown with all essential nutrients required for plant
beks73 [17]

Answer:

The plants growing on the left will be able to synthesize more required molecules in a better way as compared to the plants on the right.

As plants, on the left, will be receiving all the essential nutrients that is required for functioning properly hence, the will be bale to synthesize all the complex molecules required for growth and surviving.

On the other hand, plants on the right side, will not be able to grow properly as they will not have the required amount of nutrition.

A woman has been trying to conceive for several years, unsuccessfully. at a fertility clinic, they discover that she has blocked
pentagon [3]
The women was a carrier of the color blind trait, its recessive so she passed the trait down on his only X chromosome, men are more likely to be color blind because they only have to have one faulty X chromosome. females have to have both X's wrong.
and O is also a recessive trait so they had AO and BO blood types and the OO matched up for there baby

At the molecular level, gene duplication often produces novelty in a lineage. This process provides another evolutionary pathway
alukav5142 [94]

Answer:

Bridgham et al. (2006) showed that the interaction between a steroid hormone (aldosterone-M) and its receptor (mineralocorticoid) evolved by Darwinian gradualism. In this work, the authors demonstrated  a primitive affinity between the hormone and its receptor that was initially present in chemically similar but more ancient ligands. This result has implications in understanding the association between gene duplication and the evolution of hormone signaling pathways. For example, in invertebrates, this work reinforces the importance of gene duplication in the existing interaction between paralogous glucocorticoid receptors and their receptor mineralocorticoid genes that were derived from duplication (Thornton 2001).

The publications above cited are the following:
