D is the answer your looking for
Chemicals can make mutations by a number of mechanisms. Base
analogs are incorporated into DNA and mostly pair with the wrong base.
Alkylating agents, deaminating chemicals, hydroxylamine, and oxidative radicals
change the structure of DNA bases, thus altering their pairing properties.
Introducing agents wedge between the bases and cause single-base insertions and
deletions in replication.
What type of answer are you looking for? DNA? Or inheritance? Genes?
Answer:
Stamen/Pistil
Explanation:
Flowering plants also called Angiosperms are a group of plants characterized by the possession of flowers used for sexual reproduction. The flowers contains the male part and female part. The male part of a flower is collectively called STAMEN while the female part is collectively called PISTIL or STYLE.
The STAMEN is responsible for the production of the male reproductive structure called POLLEN while the PISTIL is responsible for the production of female reproductive structure called OVARY. During reproduction, pollen (containing male gametes, sperm) from the STAMEN are transferred to the stigma (receptive part) of the STYLE in a process called POLLINATION.
The incorrect among the choices is "<span>direct signaling involves the activation of g proteins"
This is incorrect because direct signaling does not involve the activation of g proteins rather it involves the activation of ion channels resulting to either an excitation reaction (depolarization of the membrane) or an inhibition reaction (hyperpolarization of the membrane); and this will ultimately affect the action of the organ the nerve is innervating.</span>
