D genes are present on chromosomes and control traits in an individual
Survivorship curve = so, first of all, it's a curve, as in a graph.
It describes "survivorship" - the rate of survival, in other words: out of 100 organisms that are born, how many survive. This rate is different among species, for example, most humans live out to most of their life span, and almost all can survive well beyond a reproductive age.
However, in frogs for example, many many individuals are born, but only few can survive to adulthood: most die very young, before reproductive age.
So if you hear about a new species: let's say dogs, and you want to know how long they would live, you would look at their sirvivorship curve (and in some breeds of dogs, those that are likely not to be in shelters, but in homes, the survivorship curve would be similar as in humans: almost all individuals born can live long.
Answer:
a) the molecules can be found in the picture below
b) (i) isocitrate lyase ( isocitrate to glyoxylate)
(ii) malate synthase (glyoxylate to malate)
c) Glyoxylate cycle do no exist in animals
Explanation:
b) in the glyoxylate cycle isocitrate lyase helps in conversion of isocitrate to glyoxylate. Also, helps in conversion of glyoxylate to malate by using malate synthase.
c) Glyoxylate cycle do no exist in animals, it only exist in plants and bacteria. This is because they can produce glucose from acetyl-CoA in required amounts.They have the ability to change acetyl-CoA from fat into glucose. But in animals, this mechanism is not possible.
