Mutualism is the symbiosis when both are benefited !!
Cross over is the first way genes are shuffled to give rise to genetic diversity. Cross over takes place in sexual reproduction. The normal way that cross over occurs is chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.
If they break the pieces at the same locus in the sequence of base pairs, the result is an exchange of genes called genetic recombination and it ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity occurs.
Answer:
A)selective permeability
Explanation:
it allows for it to choose ,small particles easily enter and leave the cell unlike large particles
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. That means that they will never be a copy of their parents because of their different genetic material. Characteristics, such as eye color, hair type and color, the shapes of facial features, and height and build, and attribute the combinations of these to the portions of DNA inherited from each parent which makes them different but still carry the DNA of their parents.
I think this is actually a physics question-
gravitational potential energy = mass*g*height. We know mass and g is constant, so all we need to know is the height of the basketball.
Hope this helps :)
