Yanka [14]

Growth Hormone and insulin are protein hormones that promotes the growth and regulation of substrate metabolism.

Explanation:

The Growth Hormone performs the metabolic actions in various tissues like liver, muscle, and pancreas through insulin growth factor. Insulin slows down the growth hormone signalling through the growth hormone receptor. It is important for maintaining the responsiveness of liver to growth hormone.

The insulin signalling pathway is very important in metabolic diseases like diabetes and aging. These insulin activates a phosphorylation cascade that branches to form a network affecting multiple biological processes.

balandron [24]

Answer:

the reporter gene can randomly insert near to an enhancer sequence which can induce its expression

Explanation

Enhancers are genetic sequences capable of activating gene expression by binding to specific proteins (e.g., transcription factors). Enhancers can regulate the expression of nearby genes located thousands of nucleotides away, i.e., over several kilobases away. In the human genome, it is well known that enhancers are scattered across the 98% of the genome. In this case, it is expected that the reporter GFP gene construct is randomly inserted near an enhancer sequence (a 10% chance of insertion), thereby being regulated by that enhancer.

Oksanka [162]
Taphonomists would probably conclude that hominins had scavenged meat from an animal carcass, they did not kill if fossil animal bones; did not contain stone cut marks, which are easily distinguishable from tooth marks. 
Some characteristics that have distinguished hominins from other primates, living and extinct are their erect posture, bipedal locomotion, larger brains, and behavioral characteristics such as specialized tool use, and in some cases communication through language.<span />

A cell with a predominance of rough endoplasmic reticulum is most likely ________. a cell with a predominance of rough endoplasm
amid [387]
The answer to this question would be: <span>producing large quantities of proteins for secretion.
</span>
A cell with many rough endoplasmic reticulum has a high protein synthesis capability. This will make the cell able to produce many proteins like enzyme. One example of this type of cell will be pancreas cells. This cell will need many enzymes to digest food that you eat so it will need many ER to produce it.
