I am not sure what the answer choices are for your question but I hope my answer helps.

Proteins are formed as chains of amino acids. Bonds within protein molecules will assist stabilize the structure. To add, the ending folded-forms of proteins can also be well adapted for the functions they consist of.

Compare actions of cocaine amphetamines and nicotine
Nookie1986 [14]
Nicotine on direct application in humans causes irritation and burning sensation in the mouth and throat, increased salivation, nausea, abdominal pain, vomiting and diarrhea. Predominant immediate effects consist of increase in pulse rate and blood pressure. Nicotine also causes an increase in plasma free fatty acids, hyperglycemia, and an increase in the level of catecholamines in the blood. There is reduced coronary blood flow but an increased skeletal muscle blood flow. The increased rate of respiration causes hypothermia, a hypercoagulable state, decreases skin temperature, and increases the blood viscosity.

For amphetamine the immediate effects are quicker reaction times, feelings of energy/wakefulness, excitement, increased attentiveness and concentration, feelings of euphoria. Side effects of amphetamines can include heart palpitations, dry mouth, headache, hostility, nausea, cognitive impairment, severe anxiety, lack of appetite, teeth grinding, dizziness, increased heart rate, heart palpitations, rapid breathing rate, hypertension (high blood pressure), increased body temperature, erectile dysfunction, irregular heartbeat.

Cocaine causes a short-lived, intense high that is immediately followed by the opposite intense depression, edginess and a craving for more of the drug the side effects are Loss of appetite increased heart rate, blood pressure, body temperature, contracted blood vessels increased rate of breathing, dilated pupils, disturbed sleep patterns, nausea, hyperstimulation, bizarre, erratic, sometimes violent behavior hallucinations, hyperexcitability, irritability, tactile hallucination that creates the illusion of bugs burrowing under the skin, intense euphoria, anxiety and paranoia, depression, intense drug craving, panic and psychosis, convulsions, seizures and sudden death from high doses (even one time)

11. Why<br> are<br> organisms with more similar amino acid sequences more closely related?
jok3333 [9.3K]

Answer and Explanation:

Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.

During primary succession it is the competition of resources that leads to changes/replacement of species in area over time
VMariaS [17]

Answer: False

Explanation:

During Primary Succession, an area that has just been newly exposed or is rock that has just formed newly, gets colonized for the first time by organisms.

This is not driven by competition for resources because only certain organisms can even survive in the area in the first place such as lichens or plants which then convert the area to a more habitable form for other organisms over a period of centuries.
