Answer: When a blood cells is place in Hypertonic solution, water will rush out of the cell, the cell will shrinks or crenates. This is because the solute concentration outside the cell is greater than solute concentration inside the cell.
Explanation:
Hypertonic solution is a solution that have greater or higher solute concentration outside the cell compare to the solute concentration inside the cell.
DNA stores information in a sequence of adenine, cytosine, guanine and thymine on a backbone of two deoxyribose molecules, which intertwine in a double helix. In nature, this information is read by RNA molecules and turned into proteins.
No. Not really. Genetic testing is based on things people do. And not what they are said to be.
Answer:
A) mollusc.
Explanation:
Molluscs are soft-bodied animals often covered by a 8-plated shell.
During embryonic development blastopore becomes mouth in protostomes and mollusks are protostomes.
In mollusks such as snail, sepia radula are present. Radula have row of teeth consists of marginal teeth, lateral teeth and a median tooth and are used to peel off plant parts during feeding. They also used to scrape rocks to make depression in rocks for their habitats.
Answer: C: The total mass of glucose and oxygen formed from photosynthesis is equal to the total mass of carbon dioxide and water used up during the reaction.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.
