The Golgi Apparatus is responsible for packing and shipping materials throughout the cell.
Answer:
The correct answer is - Western fence lizard
, Xenopus (African clawed frog)
, Fruit Fly
, Turtle
, and Sea urchin.
Explanation:
An ectotherm is an organism that also known as the cold-blooded animal. Such animals experience body temperature regulation based on the external atmosphere or condition like sunlight and other condition.
This group includes a different group of animals such as reptiles, amphibians, fishes, and invertebrates. From the given options the cold-blooded animals or ectotherm are known are - Western fence lizard
, Xenopus (African clawed frog)
, Fruit Fly
, Turtle
, and Sea urchin as their internal physiological conditions does not play a major role in regulation of body temperature and external conditions play a major role.
Thus, the correct answer is - Western fence lizard
, Xenopus (African clawed frog)
, Fruit Fly
, Turtle
, and Sea urchin.
Disruption of axonal transport would be a good target for his drug.
<h3>What is disruption of axonal transport?</h3>
- Axonal transport defects are among the early molecular events leading to neurodegeneration in mouse models of amyotrophic lateral sclerosis (ALS).
- Gene expression profiles indicate that dynactin-1 mRNA is downregulated in degenerating spinal motor neurons of autopsied patients with sporadic ALS.
- Disruption of axonal transport also underlies the pathogenesis of spinal muscular atrophy and hereditary spastic paraplegias.
- The neurotoxin β,β′-iminodipropionitrile (IDPN) selectively disrupts slow axonal transport without affecting fast anterograde or retrograde axonal transport.
- Impairment of slow axonal transport causes a proximal accumulation of neurofilaments.
- Because neurofilaments regulate axonal diameter, this accumulation leads to a marked swelling of the axon.
- Acrylamide causes decreased axonal transport, also causing proximal accumulations of neurofilaments and swelling.

The possible answers are:
A. Variation in length of the amino acid backbone
B. Each protein is encoded by a distinct gene
C. Variations in the type of peptide bond
D. Variations in the glycosidic linkage
E. Variation in tertiary structure
<span>F. Variations in which amino acids are used
The correct answers are A,E and F
There are only 20 amino acids that make all of the proteins in our bodies. However, there are options for protein variation are almost unlimited.
Firstly, you can vary the number of different amino acid that you use to make a protein.
Secondly, you can also vary the length of the amino acid chain.
And thirdly, when an amino acid chain is formed different parts of the chain interact with each other, bonding chemically, forming different 3-dimensional structures of the protein.
All of this contributes to the vast variation in proteins.</span>
