The majority of water molecules moving across plasma membranes by osmosis do so via a process that is most similar to simple diffusion. The process of osmosis involves the moment of water molecules across a semipermeable membrane like the cell membrane from a region of high water concentration to a region of low water concentration. This process is similar to the process of simple diffusion where the solute particles move across in a similar fashion.
Answer:
Recessive phenotype plant
Explanation:
If the plant has recessive genotype then it will be easy to identify because it will have the recessive phenotype. However if the plant has dominant phenotype it can either have homozygous genotype or heterozygous genotype. To confirm if the plant is homozygous or heterozygous, a test cross can be done with plant having recessive phenotype.
If our test plant is homozygous dominant, it will pass one dominant allele to the next generation and all the offspring would have dominant phenotype. If our test plant is heterozygous dominant it will pass one dominant allele to half of the offspring and one recessive allele to another half so 50% of next generation will have dominant phenotype and other 50% will have recessive phenotype.
Hence by test cross (cross with recessive phenotype plant) it is possible to determine the genotype of the uncharacterized pea plant.
Answer:
The correct answer is B. clavicle articulates with the manubrium of the sternum.
Explanation:
The clavicle is an anterior bone whose sternal end articulates with the manubrium of the sternum at the sternoclavicular joint. The sternal end is also anchored to the first rib by the costoclavicular ligament. The medial end, also known as the sternal end of the clavicle, has a triangular shape and articulates with the manubrium portion of the sternum. This forms the sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton.
The answer you are looking for is C.
During the day, due to the presence of sunlight, the process of photosynthesis peaks over that of respiration. Photosynthesis uses carbon dioxide to make carbohydrates releasing oxygen as a byproduct. During the night, because there is no sunlight, the rate of photosynthesis drops. This, therefore, causes the rate of respiration to surpasses the rate of photosynthesis. In respiration, oxygen is consumed and carbon dioxide is released.
