Answer:
Actually, roots, leaves, and stems are all vegetative structures. Flowers, seeds, and fruits make up reproductive structures. The roots support the plant and supply it with water and nutrients. Stems connect the roots and leaves. Plants that move water from the roots to the stems and leaves with tube-like structures are called vascular plants. ... Leaves, stems, and roots work together as a system to help the plant perform its life functions. Leaves capture sunlight and perform photosynthesis to make food for the plant.
Explanation:
Answer:The uterus has receptors for oxytocin, but not for cholecystokinin.
Explanation:
Both of the hormones are released and travel via same pathway towards the uterus. The uterus responds to oxytocin but does not responds to cholecystokinin because the uterus has no receptor for this hormone.
Cholesystokinin is secreted from gastrointestinal system and is responsible for stimulating the digestion of protein and fat.
Whereas oxytocin plays a major role in the childbirth, sexual reproduction and social bonding.

The periodic theory explains that elements would repeat their properties repeatedly. The theory also made a hypothesis that certain elements would be discovered.
The correct answer is option (A) Variation in the strawberry plants.
When the effect of fertilizer on the growth of two strawberry plants is tested, unavoidable source of experimental error is the variation in the strawberry plants. Variation refers to the deviation or differences from the normal plant which can be due to genetic variation. It is due to change in the DNA sequence. If any one of the two plants being tested show variation, the rate of metabolism differs and changes the growth pattern of the plant. The rate of absorption of water and nutrients is effected which brings change in the growth of the plant and causes an error in the experiment and the result.
