Answer:
1- substitution.
2- neutral.
Explanation:
The change in the genetic sequence of the organisms known as mutation. Mutations might be sudden and heritable in nature. spontaneous mutation and induced mutation are types of mutation.
A change that causes a change in single base pair of a gene sequence is called substitution mutation. The original leucine sequence is GTT and the mutated sequence is GTG. Thus T has been substituted by G.
Mutation can be beneficial, detrimental or neutral. The neutral mutation is that does not affect the physical change. Both GTT and GTG code for the same amino acid so it would be neutral.
The Gerobatrachus hottoni is most likely to be a phylogenic fossil.
Answer:
B.
Theories unify a broad range of observations and hypotheses.
Answer: Lysosomes synthesize proteins from the recycled amino acids.
Explanation:
This is a cell organelle with a spherical sac shape, bounded by a single membrane.( Unlike chloroplast and mitochondrial which double membranes.) It contain digestive enzymes which is hydrolytic in nature, this splits molecules by addition of water molecules. The digestive enzymes are separated from other cell organelles because of autolysis/autophagic which is automatic discharge of digestive enzymes in a contained cell which destroy the whole cell.
T<u>hey release vesicles containing the enzymes towards the target structure,and the vesicle fused with the membrane of the target cell to discharged the hydrolytic enzymes for digestion</u>
They breakdown old and worn out cells organelles, or the whole cell (for example the breakdown of mammary glands after lactation. Lysosomes are also used to digest bacterial in white blood cells by ENDOCYTOSIS.
Note: RIBOSOMES play a role in protein Synthesis not LYSOSOMES.
Their average size is 0.1-0.5µm in diameter
