The correct answer is D. Just noticeable difference.
Explanation
In psychophysics, a barely noticeable difference, usually abbreviated with lowercase letters JND, is the smallest detectable difference between an initial and a secondary level of a particular sensory stimulus. Also known as limen difference, differential threshold, or less noticeable difference. According to the above, the correct answer is D. Just noticeable difference.
Answer:
Option E, resemble fungi in their pattern of growth AND produce a number of antibiotics.
Explanation:
Streptomyces are form of bacteria's whose growth pattern resembles with fungi as they have the same filamentous form as that of a fungi. A Streptomyces can form layer of hyphae that can further differentiate to form spores. Spore formation is also a characteristics of fungi.
Almost all important antibiotics used in any medical institute are derived from Streptomyces bacteria. They produce secondary metabolites that are capable of inhibiting the rival microbes.
Hence, option E is correct.
In medusae, mesoglea comprises the bulk of the animal and forms a resilient skeleton. In polyps, the water-filled coelenteron acts as a hydrostatic skeleton, which, in concert with the mesoglea, maintains the form of these animals. Muscles in cnidarians are extensions of the bases of ectodermal and endodermal cells.
At the end of cytokinesis there no longer exists chromatids, they are just individual chromosomes.
If you're talking about Meiosis, there are 4 (HAPLOID) daughter cells produced at the end of meiosis. So each daughter cell will have HALF the number of chromosomes as the mother cell.
Whereas at the end of Mitosis there are 2 identical DIPLOID sister cells.
