Answer:
Evolution
Explanation:
Natural selection is usually defined as a process by which an organism or a specific type of living species adapts to a new environment in order to grow, develop, reproduce and protect themselves from the predators. During this time of migration, evolutionary changes occur in organisms over a specific period of time. It occurs naturally and there are several factors that affect these changes occurring in an organism.
Evolution simply refers to the growth, development, and expansion of an organism that occurs over a definite time period.
Which process is a "build up" process? ___anabolism___
which process is a "break down" process? ___catabolism___
photosynthesis occurs in __the chloroplasts__
cellular respiration occurs in __the mitochondria__
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.
In eukaryotic cells the DNA can be found in the nucleus mainly. so DNA replication takes place in the nucleus during the S phase of the cell cycle.
Also in eukaryotic cells there are mitochondria and chloroplasts (plants) and these have circular DNA and they also get replicated (according to their own mechanism).
Prokaryotic cells don't contain a nucleus. They do not contain DNA in the cytoplasm and thus the DNA replication will take place here.
I really hope this helps!
