<h3>
<u>Answer and explanation;</u></h3>
<u>Zone of resting cartilage</u> is nearest to the epiphysis and contains randomly arranged chondrocytes that do not divide rapidly.
<u>Zone of Proliferation</u> produce new cartilage through interstitial cartilage growth. Chondrocytes divide and form columns resembling stacks of plates or coins.
<u>Zone of hypertrophy.</u> The chondrocytes produced in the zone of proliferation mature and enlarge, the cells nearest the diaphysis are older and undergoing hypertrophy.
Thus, a maturation gradient exists in each column: The cells nearer the epiphysis are younger and actively proliferating, whereas the cells progressively nearer the diaphysis are older and undergoing hypertrophy.
<u>Zone of Calcification</u> is a very thin zone that contains hypertrophied chondrocytes and calcified cartilage matrix. calcified cartilage is replaced by bone.
The hypertrophied chondrocytes die, and blood vessels from the diaphysis grow into the area.
Answer:
Option 2
Explanation:
The information given by an age distribution about a population is the <u>number of individuals within each age range</u>.
Answer:
melanopsin
Explanation:
this note might help you :
The retinohypothalamic tract (RHT) is a photic neural input pathway involved in the circadian rhythms of mammals. The origin of the retinohypothalamic tract is the intrinsically photosensitive retinal ganglion cells (ipRGC), which contain the photopigment melanopsin. The axons of the ipRGCs belonging to the retinohypothalamic tract project directly, monosynaptically, to the suprachiasmatic nuclei (SCN) via the optic nerve and the optic chiasm. The suprachiasmatic nuclei receive and interpret information on environmental light, dark and day length, important in the entrainment of the "body clock". They can coordinate peripheral "clocks" and direct the pineal gland to secrete the hormone melatonin.
information about melanopsin : Melanopsin is a type of photopigment belonging to a larger family of light-sensitive retinal proteins called opsins and encoded by the gene Opn4.[5] In the mammalian retina, there are two additional categories of opsins, both involved in the formation of visual images: rhodopsin and photopsin (types I, II, and III) in the rod and cone photoreceptor cells, respectively.
biology as a whole scientific study of life, where as zoology is the scientific study of animals(and their lives).
The substance that bind to specific antigens on pathogens causing them to clump together is option A which is antibodies and this is to fight against the pathogens and render them inactive in the human bodies
<h3>What is antibodies?</h3>
Antibodies are proteins or substances that is secreted by organs in the body or hormones which help to fight against foreign substances that invades the body or fight against pathogens that might want to cause diseases or inflammation in the body.
Therefore, The substance that bind to specific antigens on pathogens causing them to clump together is option A which is antibodies and this is to fight against the pathogens and render them inactive in the human bodies
