1. Platypus, Brown Bear, Lion, and House Cat.
2. Brown Bear.
3. House Cat.
In this graph you are basically going down the line (or up towards the house cat) looking at the qualities each animal has. So whatever is on the bottom (hair and mammary glands) all animals above it has it. If the quality passes the animal, the animal doesn’t have that quality.
Hopefully this explanation is clearer with the answers.
Answer:
Genetic drift
Explanation:
Based on the information given here, the observed genetic variation is most likely an example of Genetic drift .
Genetic drift is the variation in the relative frequency of different genotypes in a small population, owing to the change disappearance of particular group of genes as individuals die out do not reproduce.
The above mentioned information indicate a typical example of Genetic drift
Answer:
Embedded in the lipid bilayer are large proteins, many of which transport ions and water-soluble molecules across the membrane. Some proteins in the plasma membrane form open pores, called membrane channels, which allow the free diffusion of ions into and out of the cell.
Answer:
B tissue level
Explanation:
B tissue because whatever substance that got into the lungs will cause the tissue to swell up causing an asthma attack
Answer:
These are the following answers to the items:
Pinocytosis -cell engulfs molecules in cell "drinking"
Facilitated diffusion- molecules helped by protein; move insoluble molecules
across plasma membrane
Passive diffusion- molecules move in and out freely from high to low concentration
Phagocytosis- cell engulfs microorganisms in cell "eating"
Active transport- molecules "pumped" in or out from low to high concentration
Passive diffusion- oxygen, carbon dioxide
Active transport- transports sodium, potassium
Pinocytosis- transports glucose, amino acids
