Answer:
True-breeding plants.
Explanation:
The self pollination in plants that produces progeny with similar characteristics or traits is called True-breeding plant. The parent and progeny both are identical genetically in true-breeding plants. The alleles shared between both offspring and parental plant is also same. The homozygous alleles are present in such organisms. The presence of homozygous alleles mean both alleles are same thus resulting in similar characters. Thus, plants that if left to self pollinate produce offspring identical to themselves are called True-breeding plants.
Answer: The answer is option C

Beta carotene is an organic, red-colored pigment that is found to be abundant in plants and fruits. it is a member of the Carotenes. Beta carotene is an inactive form (precursor) to vitamin A.
Ans.
Steroids are defined as active organic bio-molecules, having four rings with a specific molecular configuration. Steroids play role in two major functions: as hormones or signaling molecules and as structural components of plasma membrane.
Examples of steroid hormones are estrogen, progesterone, and cortisol. Thus, the correct answer is 'option b). they serve as chemical messengers.'
