A researcher observing an ecosystem describes the amount of sunlight, precipitation, and type of soil present. The researcher is most likely describing abiotic factors in a prairie.
A and B are incorrect because the factors described are abiotic, not biotic.
Di is incorrect because abiotic factors listed include soil, which is not likely to be described in an ocean environment.
Answer:
c = Enzymatic activity
e = Attachment to ECM and cytoskeleton
f = Signal reception and relay
g = Transport
h = Intercellular junctions
i = Cell-cell recognition
a = Phospholipid bilayer
b = Fibers of extracellular matrix (ECM)
d = Microfilaments of cytoskeletons
Explanation:
c) Enzymatic activity is an indication of the amount of active enzymes present to increase a reaction rate
e) Attachment to ECM and cytoskeleton is enabled by integrins that take signals from the ECM and control signaling pathways of the cell
f) Signal reception and relay is the transduction of signal
g) Transport is the movement of matter in and out of the cell through the cell membrane
h) Intercellular junctions are the contact regions between adjacent cells and plasma membrane
i) Cell-cell recognition is power of the cell to decipher the different neighboring cells in the cell's environment
a) Phospholipid bilayer consists of a hydrophobic interior and a hydrophilic exterior
b) Fibers of extracellular matrix (ECM) are ECM associated the cell
d) Microfilaments of cytoskeletons consist of actin and aid in cellular movement.
Answer:
D - the production of a specific mRNA will increase as a result of the binding of the hormone receptor complex to the DNA
Explanation:
We are told that the hormone binds a receptor and then enters the cell, binding to the DNA and promoting transcription of a specific gene.
Transcription is the process whereby mRNA molecules are synthesised from a DNA sequence, which are then translated into specific process. D is correct, as the gene the hormone binds to will increase in transcription, producing a specific mRNA.
A, B and C are much more general processes, not linked to the actions of a hormone on a specific gene.
It would be hotter. But what are your options for an answer <span />
