The accurate statements to the signal transduction pathways are as follows:
1. A receptor changes conformation upon attachment, conducting a signal across the cell membrane.
2. A second messenger may carry a signal from the cell membrane to an organelle.
3. Signal transduction cascades, often involving protein kinases, amplify a signal intracellularly.
4. A receptor may pass on a signal by associating with another protein or by functioning as an enzyme.
5. A ligand, like hormone, combines with a specific cell surface receptor on a target cell.
6. Phosphatase eradicate phosphoryl groups from polypeptides, monitoring the response of the cell.
Answer:
things such as termites, slugs, scorpions, worms, and fungi
The answer is A, population growth increases .
—Explanation—
•] The definition of limiting factor; anything that constrains a population's size and slows or stops it from growing.
•]Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.
•] So if the limiting factor is removed then the population begins to expand due to not having a factor that limits each species quantity.
Answer:
The plasma membrane is selectively permeable
Explanation:
hydrophobic molecules and small polar molecules can diffuse through the lipid layer, but ions and large polar molecules cannot. Integral membrane proteins enable ions and large polar molecules to pass through the membrane by passive or active transport.
The ears are involved in balance, but it's more than just them.
Your eyes are also important, as well as your body's sense of where it is in space.
