Answer:
B. Proteins are tethered to the extracellular matrix
Explanation:
The assembly of nascent focal adhesions is strongly dependent on the process of actin flow, happening in migrating cells when the actin filament polymerize at the edge and flow back towards the same cell's body.
That is what causes the traction needed for migration, when the focal adhesion works a support when it tethers to the extracellular matrix and impedes the backward move of actin, generating the traction force needed at the point of contact to move the cell forward.
The hottest layer, has very stable air
Answer:
To maintain this balance, the Hardy-Weinberg Equilibrium Principle states that a population should meet five main assumptions. There should be random mating, large population size, no mutation, no selection on the gene in question, and no gene flow in or out of the population.
Explanation:
Answer: body systems that can directly impact fluid balance includes:
b)urinary system
c)respiratory system
f)sweat glands.
The correct option is B, C and F.
Explanation:
Homeostasis is the mechanism by which the body maintains a steady ( constant) internal physical and chemical conditions. The following variables needs to be kept in equilibrium for optimal functioning of the body system. They includes: the body temperature, fluid balance, blood sugar levels. These variables are in turn controlled by one or more regulatory systems which includes;
- urinary system:when blood volume gets too low or blood electrolytes get too concentrated, the kidneys can retain water thereby decreasing urine output. When blood volume or pressure is too high, the kidneys can excrete more water thereby increasing urine output.
- sweat glands: this regulates both fluid and temperature.
I hope this helps. Thanks
