Answer:
Bed bugs belong to the Cimicidae family (that's Latin for bloodsucking wingless bugs). They come in the order of Hemiptera.
Answer:
Transcriptional regulators function to regulate the expression of different genes and also to affect the expression of other transcriptional regulators, thereby the combination of a few transcriptional regulators is sufficient to modulate gene expression patterns
Explanation:
Transcriptional regulators are able to control gene expression by binding to cis-regulatory elements on the genome. For example, in plants, MADS-box proteins are transcriptional regulators that contain an evolutionary conserved DNA-binding domain (i.e., MADS-box domain) which regulate simultaneously the expression of many different genes by binding to a conserved DNA motif called CArG box [CC(A/T)6GG] located in the promoter region of many genes expressed at specific stages of plant development. Within the cell, transcription regulators function not only by controlling the expression of different genes but also by affecting each other's activity, thereby creating different combinations where the expression of a limited number of transcription regulators is sufficient enough to regulate gene expression patterns.
Many cacti have roots that spread out widely, but only penetrate a short distance into the soil. In one case, a young saguaro only 12 cm (4.7 in) tall had a root system with a diameter of 2 m (7 ft), but no more than 10 cm (4 in) deep.
In other words they can't penetrate that deep.
yes that is correct, what's your point?
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when organisms from one trophic level are consumed by organisms of the next level. More specifically, 90% of metabolic energy is used, so only 10% will be passed down to the next level.
