Answer:
Because offspring with two parents will share half of each parent's DNA.
Explanation:
Sex cells contain half of the genetic information of an organism's regular cells. This is because a sexually-produced organism will be unique; it will share genetic information with both of its parents, rather than be identical to its bearer (like an asexual organism would be). When a sex cell meets another sex cell, their DNA will meet as well and change/adapt to suit the organism. If a sex cell had all the information needed to create an embyro, instead of half, which requires another cell's information to fill the DNA void.... well, it would just do it.
Answer:
Their answer about the location or function of the cells.
Explanation:
Since there are no options to select as the answer, i will just try my best to list a couple of them.
Langerhans Cells are from the family of cells named "Dendritic Cells" because of their tree like shapes. They can be found on parts of our body that come into contact with foreign environments or particles, such as skin, on the inside of our mouth, nose and stomach etc.
The nursing instructor could evaluate the students' knowledge by asking them where Langerhans Cells are located in our body, on which layer of our skin they can be found or what their primary functions are.
I hope this answer helps.
answer is antibodies.
B cells are a type of lymphocytes and it is responsible for the immune system. B cells help to protect body by producing specific antibodies to fight against each antigen which are strangers to the body specially for viral infections.
Answer:
Some substance in the infectious S strain could change the harmless R strain into the more lethal form.
Explanation:
These first type of experiments where crucial to advance in DNA knowledge.
In one experiment, they treated the material with enzymes that destroy all proteins. This is important because scientist notice that there was something else that was causing the strain to change into a lethal form and was heritable (DNA). Know a days we know that plasmids are responsible for such transformation.
