Answer:

The best answer to the question: Why is it that two full siblings can be equally related to a given grandparent, even though both of them have received equal amounts of DNA from their mother and father? Would be: Genetic recombination.

Explanation:

When an offspring receives chromosomes from the father´s sperm and the mother´s egg, a process takes place to ensure that these chromosomes appropriately combine and the balance is maintained on the total number of chromosomes and also on which gene will be phenotypically expressed on one offspring, and which in another. This process is called genetic recombination and basically it is a shuffling of genes. This means that the parents of the two full siblings each received a copy of chromosomes from both their own parents, one of which would be the grandparent of the full siblings. But as meiosis takes place and the chromosomes fuse, shuffling, or recombination takes place, and while one offspring will receive a given set of genes, the other may receive the same, or another set. This means that as generations are born, genetic material from the grandparent will further recombine with those of others present and the percentage of genetic material directly linked to that grandparent will diminish, but will not completely disappear. Thus, genetically, we will be linked to the progenitor line, but the percentage of genes directly received will lessen.

How much work is done on a 100-N boulder when you lift it 2m straight up?
zzz [600]

200J

Explanation:

Given parameters:

Force on boulder = 100N

Distance moved = 2m

Unknown:

Work done = ?

Solution:

Work done on a body is the force applied to move such body in the direction of the force.

           Work done = force x distance

Input the parameters in the equation:

       Work done = 100 x 2 = 200Nm or 200J

The work done in lifting the boulder is 200J

Describe one way osmosis and osmotic pressure is important to medicine.
OleMash [197]

Answer:

Since the beginning of life of the first multicellular organisms, the preservation of a physiologic milieu for every cell in the organism has been a critical requirement. A particular range of osmolality of the body fluids is essential for the maintenance of cell volume. In humans the stability of electrolyte concentrations and their resulting osmolality in the body fluids is the consequence of complex interactions between cell membrane functions, hormonal control, thirst, and controlled kidney excretion of fluid and solutes. Knowledge of these mechanisms, of the biochemical principles of osmolality, and of the relevant situations occurring in disease is of importance to every physician. This comprehensive review summarizes the major facts on osmolality, its relation to electrolytes and other solutes, and its relevance in physiology and in disease states with a focus on dialysis-related considerations.
