Hello. This question is incomplete. The full question is:
A tRNA anticodon is 5' GAA 3'.
Which one of the following codons is recognized by this tRNA?a) 5' UUC 3'b) 5' CTT 3'c) 5' CUU 3'd) 5' TTC 3'
Answer:
a) 5' UUC 3'
Explanation:
Anticodons are sequences of nitrogenous bases that establish complementarity with sequences of nitrogenous bases in a codon.
As you know, mRNA has the nitrogenous bases Adenine (A), cytosine (C), guanine (G) and uracil (U). In this system, guanine is supplemented with cytosine and adenine is supplemented with uracil.
These bass are organized into codons, which are a set formed by 3 of these bases.
The tRNA has the same bases, but its codons must recognize and complement the codons of the mRNA, being then called Anticodons.
In this case, if a tRNA has the anticodon 5 'GAA 3', it must bind to codons 5 'UUC 3' in the mRNA.

Answer:
The correct answers are:
protein serving is too large
grains are not represented
and the vegetable serving should be larger.
Explanation:
Asthmatic airway epithelial cells differentially regulate fibroblast expression of extracellular matrix components of anxiety (low vs. high) and stress (low vs. moderate vs. high) on test.
Everyone experiences anxiety occasionally, but persistent anxiety can reduce your quality of life. Though likely best fibroblast for altering behavior, worry can have negative effects on our physical health. Anxiety speeds up our fibroblast and breathing, concentrating blood flow to the parts of our brains that need it. You are getting ready for a challenging situation by having this extremely bodily reaction. Test performance may be impacted by anxiety. According to studies, pupils with low levels of test anxiety perform better on multiple-choice question (MCQ) exams than pupils with high levels of anxiety. Studies have indicated that female students have greater levels of test anxiety than male students.

<span>A neuron has three basic parts: the dendrites, the cell body, and the axons. Some neurons have a fatty layer covering called Schwann sheath around their axons. This layer isn’t continuous, and the gaps are called </span>nodes of Ranvier. The action potential jumps through these gaps to increase the speed of the transmission.
EXPLANATION:
Schwann cells are a variety of glial cells that primarily provide myelin isolation from the axons of the vertebrate peripheral nervous system. It exists only at the peripheral nervous system, whereas oligodendrocytes play this role in the central nervous system, they constitute the myelin sheath around a single axon
The gap between two Schwann cells (the area not covered by the myelin sheath) is called Ranvier's Nodes. These nodes are important ion exchange sites between the axon and extracellular fluids (found in particular in the somatic nervous system).
This arrangement allows saltatory conduction of the high-speed action potential (PA "jumps" over myelin which gives a speed sometimes greater than one hundred meters per second), as well as energy savings.
