Answer:
It is possible to determine their functions and to identify the mechanism involved in their mode of inheritance
Explanation:
Matrilineal inheritance refers to the inheritance of genes directly from the mother, it either through the inheritance of mitochondrial DNA or by the epigenetic mechanism of genomic imprinting (in the case above indicated, maternal imprinting). By mutating genes which are inherited from the mother it is possible to study their functions as well as their mode of inheritance. By using a reverse genetics approach, many maternal imprinted genes have recently been identified to be involved in embryo development, especially in model organisms like <em>Drosophila</em>.
An isotonic solution is when the solute concentration is balanced with the concentration inside the cell , the water movement still moves between the solution, but the rates are the same in both directions, the water is balanced inside and outside the cell .
A hypotonic solution is when the solute concentration is lower than the concentration inside the cell. water moves into the cell and can cause the cell to swell; cells that don’t have a cell wall, such as animal cells, could explode in this type of solution.
A hypertonic solution is when the solute concentration is higher than the concentration inside the cell. In a hypertonic solution, the water moves out of the cell and causes the cell to shrivel.
Answer:
b. a greater chance to survive if environmental conditions suddenly change
Explanation:
When a species of organism has a wide variety of characteristics, it means that that species has many opportunities to adapt and survive different environmental conditions, even if those conditions change suddenly. This is because, this variety of characteristics allows this species to adopt the most variable survival strategies.
Humans evolved 3 billion years ago after the earth was formed.<span />
Answer: Generally, these factors are based on two things: hydrostatic pressure and osmotic pressure. Water will only flow across a membrane firstly if the membrane is permeable to water.
