Answer:
B. Fossil
Explanation:
According to National Geographic, "Fossils are the preserved remains, or traces of remains, of ancient organisms." When you find the impression of a leaf, the leaf imprint is the preserved remains of the leaf.
Answer:
Option 1.
Explanation:
r-selected species may be defined as the species that has higher growth rate, shows less parental care and the rate of survival of the off spring is low as compared with k selected species.
Black widow spiders have the ability to produce 1000 offspring. Their chances of survival are extremely low and only few species of black widow spiders survive. Hence, black widow spider is r-selected species.
Thus, the correct answer is option (1).
All cells I’m pretty sure
Gout is a complex form of arthritis which is caused by a build up of uric acid. The particular patient population that is always affect is those who have high quantity of uric acid in their blood. The common cause of this medical condition is excess amount of uric acid that is present in the blood. The condition is characterized by severe pain,inflammation, redness and tenderness of joints.
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.
