Yes. The gradient determines the direction of movement for particles. Diffusion and osmosis are both examples of passive transport Osmosis is the diffusion of water through semipermeable membranes like the cell membrane
The particles will move from an area of high concentration to an area of low concentration. This direction of movement is described as movement *with* the concentration gradient.
Answer:
An organism would need a 4 chambered heart.
Explanation:
The heart consists of 4 chambers in which blood flows freely. Right atrium, left atrium, left ventricle and right ventricle.
The pulmonary arteries carry de-oxygenated blood to the lungs from where CO2 is released and O2 is picked up during the process of respiration. The pulmonary vein then takes the oxygenated blood to the left atrium of the heart and then to the left ventricle of the heart.
Each body cell contains the same number and kinds of chromosomes for that organism. The chromosomes contain the same number and kinds of genes for that individual.
Antibiotic resistance happens naturally due to genetic mutation through random selection, however, genetic drift occurs on purpose and tests which genes are stronger and should continue to be passed on to future generations. In most cases, genetic drift is needed and antibiotic resistance isn’t.
