The right answer for the question that is being asked and shown above is that: (1) removing metabolic wastes from the body; (2) urea is not soluble in water; (3) simple diffusion across the skin; (4) They both actively pump salt across their gills; (5) <span>They both produce lots of diluted urine."</span>
Remember the definition of Osmosis; Water travels through a semipermeable membrane to an area of higher to lower concentration. Since the concentration of a solute is higher outside, we can make the assumption that water concentration is lower, and so the cell is going to release water to balance out and equalize the solution and it's surroundings.
Answer:
effector
Explanation:If the value is not at the set point or is outside the normal range, the control center sends a signal to the effector. The effector is an organ, gland, muscle, or other structure that acts on the signal from the control center to move the variable back toward the set point.
Answer:
Due to different pigments.
Explanation:
The multicellular algae are red, green and brown because of the presence of pigments. The red algae are red in colour because of the presence of the phycoerythrin which is a type of pigment. This pigment reflects red light due to already presence in its body and absorbs blue light that is necessary for photosynthesis process. The brown algae contain fucoxanthin pigment and green algae contain xanthophylls pigments that are responsible for its colour so we can conclude that these different types of pigments are responsible for the different colour of algae.
