Because smoking can cause many different bad things to happen to you some examples would be lung cancer or if you smoke while you are pregnant you cold cause premature or birth defects to the baby, alcohol can just be bad a lot of the time because people can become addicted and loose a lot of money on buying alcohol and/or smoking materials.
Answer:
Exoskeletons provide less mechanical leverage.
Explanation:
There are two types of skeleton in living beings: the endoskeleton (which vertebrates possess, is lined with epithelial tissue and has bones and cartilage) and the exoskeleton, a skeletal structure that is located outside the body of the living being. , is an external skeleton. They are common in invertebrate animals, which have no internal bone structure.
The exoskeleton is a tough but flexible outer layer, not formed by bones, unlike the vertebrate endoskeleton. Its function is mechanical, chemical and biological protection, avoid excessive water loss, muscle support and serves as a connecting point for legs, wings and other appendages. However, this type of skeleton provides less mechanical leverage.
On the other hand, the endoskeleton is the name given to the internal skeleton, which is inside the body. This body structure is mainly seen in vertebrate animals and has the function of supporting and moving the body, as well as protecting some internal organs. Unlike exoskeleton, the endoskeleton provides more mechanical leverage.
Answer:
a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape,2 (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.
Summary. Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water
Initiation:
In the cytoplasm, protein synthesis is actually initiated by the AUG codon on mRNA. The AUG codon signals both the interaction of the ribosome with m-RNA and also the tRNA with the anticodons (UAC). The tRNA which initiates the protein synthesis has N-formyl-methionine attached. The formyl group is really formic acid converted to an amide using the -NH2 group on methionine (left most graphic)
The next step is for a second tRNA to approach the mRNA (codon - CCG). This is the code for proline. The anticodon of the proline tRNA which reads this is GGC. The final process is to start growing peptide chain by having amine of proline to bond to the carboxyl acid group of methinone (met) in order to elongate the peptide.
