relationships aren't everything. people everyday spend there entire life depending on reltionships and for someone to be there for them when this is absurd. why must people depend on someone else to bring them happiness? i'm not saying it wrong to feel happy with someone, but people feel that they need to be in a relationship in order to feel happy, when, this is not true. you can paint, write, read ir slend tume with family ir even spend time working in yourself. this can be an exciting experience to find yourself. it's bot wrong to be in a relationship but if you let it be your only source of happiness, than you will never find true happiness.

so, relationships are not always worth it. if you are so dependent on them, than in the end they arent worth it because you will realize how unhappy you really were. some people even tend to cut ties with family because they think they cabt make them happy, obly realtionships with a lover can. false. in order to find true happiness, one must learn to love themselves if they want to love someone else. it's unhealthy to be always depend on relationships and to alqays be in and out of one.

so live life, get that job you always wanted, buy those new shoes and love yourself. depend on yourself, not others. they arent worth it, you can make yourself more happier than most people can do to you. it's not woth it. take your time and have fun.

Answer from: Quest

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of amino acids , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in genes . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called transcription ), and the mrna is transported to the ribosome . protein synthesis, also called translation , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the nucleotides of mrna three by three, in units called codons , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the amino acid chain goes on to be processed and folded to make the final, functional protein

Answer from: Quest

answer: zinc is the substance which has a volume of 1.38 $cm^{3}$ .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e. $density = \frac{mass}{volume}$

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula $volume = \frac{mass}{density}$ .

hence, the volume of aluminium will be = $\frac{4.60}{2.70} cm^{3}$ which comes out to be 1.703 $cm^{3}$ .

similarly, volume of zinc, chromium, and nickel will be 1.378 $cm^{3}$ , 0.869 $cm^{3}$ , and 0.356 $cm^{3}$ respectively.

On a backpacking trip, kenny hikes all day at a steady pace, covering 30 kilometers and burning 4000 calories. at the school track, janelle runs the 100-meter sprint in 13.5 seconds, burning 10 calories. afterward, janelle’s leg muscles are aching and she is breathing hard, while kenny maintains normal breathing all day, even though he burns 400 times more calories than janelle. which two statements offer the best explanation for this phenomenon? a. if the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt." b. aerobic cellular respiration produces more energy, but its use is limited because of lactic acid buildup in the muscles and the resulting "oxygen debt." c. after about 90 seconds of intense exercise, the muscles become depleted of oxygen, and anaerobic respiration can no longer function to produce atp, resulting in "oxygen debt." d. the rate of energy demand determines how the muscles will obtain energy, either from cellular respiration or from lactic acid fermentation if not enough oxygen is present.
