Answer:
The correct answer is D. levator scapulae.
Explanation:
The levator scapulae is the muscle involved in the scapula lifting, as it's located on the sides and back of the neck. As the person's head is protruding forward it's highly possible that the muscle involved is the <em>levator scapulae. </em>
C. natural selection.
This is because in smaller populations the more that two separate groups of animals don’t interbreeding the father they become until speciation occurs where they cannot interbreed between the two groups.
The correct answer is option A, that is, saturated.
The mentioned lipid is not a phospholipid, as it does not comprise a phosphate group at the terminal of the chain, and is not a triglyceride due to the absence of glycerol moiety.
Each carbon combined with the hydrogens forms the maximum number of possible C-H bonds, thus, there are no multiple bonds between the carbons. Hence, it can be concluded that the lipid is saturated.
Answer:
Option A: True
Explanation:
Insectivorous birds such as bluebirds, dippers and flycatchers prefer to eat medium-sized insects. This is because like most birds, they love easy and satisfying meals. To the birds, a medium-sized insect is a good compromise because it is quite easy to chew and digest and at the same time, easy to find.
As a result, most insectivorous birds prefer to get their daily ration of proteins from the medium-sized birds.
Answer: b. Acetyl Co-A
Explanation:
Acetyl CoA produced through pyruvate, amino acids, and fatty acids are oxidized in the Krebs cycle in CO2, obtaining as products NADH, FADH2 and GTP (ATP). Parallel to this oxidation, the Krebs cycle produces compounds used as precursors for biosynthesis. As it is a cycle, an oxaloacetate molecule could, in principle, oxidize an amount indefinite of acetyl CoA. Acetyl-CoA is formed from the oxidative decarboxylation of pyruvate, sequentially performed by pyruvate dehydrogenase -PDH (complex multi enzymatic of 3 enzymes), in the mitochondrial matrix.
