Answer:
D) integrins
Explanation:
The extracellular matrix is an intricate network of carbohydrates and proteins in the cells extracellular space. <em>Collagen proteins </em>undergo modification with carbohydrates within the cell to form collagen fibers; they are interwoven with proteoglycan complexes is made up of carbohydrates proteins and polysaccharides. The resulting mesh is capable of providing structural integrity, mechanical strength and support to tissue.
In the ECM, the fibers are joined to integrins by fibrobronectin bridges. Integrin proteins form crucial connections between surrounding cells, are embedded within the cells' plasma membranes and anchors them in the ECM. Also, they facilitate cell communication in the environment- <u>they are capable of detecting mechanical and chemical signals</u> from the ECM and respond by stimulating signal pathways inside the cell.
Answer:
Given merely 40 butterflies were marked, assumed that there were multiple captures of both marked and unmarked butterflies, that the butterflies caught in traps were on the loose to be caught again. There are two mathematical solutions for this, both yielding the same answer which is 100.
• First, to each marked butterfly was taken twice (40 marked X2 = 80 captured) then of the unmarked butterflies the 120 captured must relate to 60 actual butterflies. In which 40 + 60 = 100.
• Secondly, by means of ratios in which 80/200 = 40/X. In this case X also = 100 that will result to the estimated size of the population of wilson park is 100.

Answer:
Yes
Explanation:
Hormone is responsible to mediate change in the cell by binding to the hormonal receptor present on the cell. So hormone only acts on the cells which have the specific receptor for that hormone.
One cell can have many receptors for a single hormone which defines the sensitivity of cell for the hormone which is responsible for generating appropriated cellular response in the cell.
So the number of receptors on the cell can contribute to different responses of cells having the same hormonal receptor. Every cell also have unique transduction pathway which is also responsible for different response of cell.
The adaptation that helped plants survive on land are vascular systems.
This means that when plants became vascular plants, they were able to start living on land because the elements of the vascular system helped them take water and nutrients from the soil, and in return emit oxygen into the atmosphere around them.
