Answer:
In a broad sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.
Explanation:
Answer: Weak.
Explanation:
The complete question is:
Scientists use a substance called Iodine-131 to treat cancer. As Iodine-131 undergoes radioactive decay and emits beta particles, it kill cancer cells. Which fundamental force is being used in this type of treatment?
Well, here we have beta decay.
Beta-decay is when a beta particle (an electron or a positron) is emitted from an atomic nucleus (usually a neutron-rich nucleus). We know that beta decay is a consequence of the weak force or weak interaction (the force responsible for the radioactive decay of atoms)
Then the correct option is the second one, weak.
Cratering, Erosion, Volcanoes and Weathering
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.
