Biology

xeze [42]3 years ago

Answer:

When occurs in gametes

Explanation:

Mutations are changes in DNA sequence that can create genetic variation within the population and thus are the ultimate source of new alleles . Mutations can occur as a result of mistake during the DNA replication, under the influence of environmental factors (UV radiation, chemical agents). They can be harmful, beneficial, neutral. Based on the location of cell mutation, they can be divided into:

  1. somatic mutation-within the somatic cells, these mutations affect only the parents (not inherited)
  2. germline mutation-within gametes, can be inherited on offspring.

Carley has become operantly conditioned.

Explanation:

Operant conditioning can be described as a method of learning which focuses on the rewards or punishments that will be given in course for an action.

1.what did magnesium and oxygen atoms had to do to bond ?
devlian [24]

Answer:

1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).

2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.

3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

Which cells harvested from adult mice were most likely used as the highly proliferative benchmark?
Ilia_Sergeevich [38]

Gastrointestinal epithelial cells. The epithelial cells that like the gastrointestinal tract are typically HIGHLY PROLIFERATIVE. Cells that line gastrointestinal tract. Cells proliferate and produce plasma cells. The plasma cells bear antibodies with the identical antigen specificity as the antigen receptors of the activated B cells.
