What is the biochemical process occurring in a plant cell the produces oxygen

Plz fast biotechnology is a growing field of applied biology. many crops such as corn have been engineered to be resistant to herbicides. therefore farmers can spray these chemicals to kill weeds growing near the crop without worries of killing the crop itself how does this type of biotechnology work? a. by changing the genetic make up of the crops. b. by causing the crops to kill the weeds. c. by changing the type of crops used. d. by changing the location of the crops.

Alternation of generations in angiosperms the diagram below illustrates the alternation of generations that is characteristic of the angiosperm life cycle. label structures and processes (using white labels), indicate whether different structures are haploid or diploid (using pink labels), and indicate the types of cell division that occur at different points in the life cycle (using blue labels). drag the labels to their appropriate locations on the diagram of the angiosperm life cycle. labels can be used once or more than once. use only white labels for white targets, pink labels for pink targets, and blue labels for blue targets. a. meiosisb. haploidc. mitosisd. ametophytee. pollinationf. meiosisg. haploidh. mitosisi. ametophytej. fertilizationk. zygotel. diploidm. sporophyte

Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. they identify the gene responsible for toxin production. the dominant allele (t) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. heterozygotes produce an intermediate amount of toxin. the genotypes of all individuals in the population are determined (see chart) and used to determine the actual allele frequencies in the population.is this population in hardy-weinberg equilibrium? a) yes.b) no; there are more homozygotes than expected.c) no; there are more heterozygotes than expected.d) more information is needed to answer this question.
