Ans. (B). Genes.
The chemicals that kill the weeds are known as herbicides. Herbicide-resistance is defined as the inherited ability of weeds to survive an application of herbicide, that can kill a normal weed plant of same species.
The resistance develops due to mutations in genes that were sensitive to those chemicals in wild-type forms. As genes are responsible for transfer of characteristics from one to another generation, the herbicide-resistance is also passed down to generations through genes.
Thus, the correct answer is option (B).
Lamarck represented the hypothesis that an organism can pass on acquired characteristics during its lifetime to its offspring. This theory was rejected, but nowadays discoveries in the field of epigenetics and somatic hypermutation confirmed part of it and highlighted the possible inheritance of behavioral traits acquired by the previous generation.
An organisms metabolism doesn't quite invilve sleeping by the idea that metabolism is greatly enhance when one has a stimulus of generated cells (thanks to the assistance of hormonic means). Metabolism can be formulated better, however, metabolism does not really involve sleep.
Alleles or genes m8. Could also go with traits maybe but that’s not as specific
The answer would be: anterior pituitary
Hypothalamus secretes many hormones that will bind to anterior pituitary and makes it secretes many kinds of tropic hormones. Anterior pituitary able to secrete gonadotropic, somatotropic, thyrotropic, lactotropic, or corticotropic hormones. All these hormones will have to travel to their specific endocrine glands.
