Answer:
Experimental or interventional studies compare the effect of treatments or interventions with control in humans. Placebo or different treatment(s) or intervention(s) may be used as control. Experimental studies have to be transparent and evidence-based. Two examples include clinical studies as well as observational drug studies.
Answer:
the genotype is responsible for a particular trait or all of the traits
Explanation:
The answer is; A
In pteridophytes, the sporophytes (of the haploid stage) produce spores. The diploid stage in pteridophytes may occur when tow spores fuse and develop into a prothallus (diploid stage of the pteridophytes).
Fungo too produces spores by the sporangiophores (haploid stage). Occasionally, two horizontal hyphae between two species of fungi, may fuse at the tips and form a zygote through karyogamy and plasmogamy.
Answer:
Endocrine disruptors are the synthetic or natural chemicals that may interfere with the functioning of the endocrine system in the human body. These chemicals mimic the naturally occurring hormones produced in the body like estrogen (a female sex hormone) and androgen (a male sex hormone) also these interfere with the production of the thyroid hormone. They bind to the receptors present in a cell and prevents the endogenous hormone from binding. The normal signaling process fails to respond properly.
Chemicals that functions as endocrine disruptors include dioxine, polychlorinated biphenyls (PCBs), pesticides and DDT.
