Answers
Answer:
C
Explanation:
You make two agar plates: one is a nutrient agar plate (plate A) that contains histidine and penicillin. The other is a glucose salts agar (plate B) that also contains penicillin. You inoculate a sample onto both plates using replica plating technique, incubate the plates, and compare the growth after 48 hours. There are 12 colonies on the nutrient agar plate and 11 colonies on the glucose salts medium. Which of the following statements is INCORRECT?
a. The colony that is missing from plate B is an auxotroph that cannot synthesize histidine.
b. The prototrophs are resistant to penicillin but the auxotrophs are sensitive to this antibiotic.
c. Prototrophs and auxotrophs in this experimeſit are resistant to penicillin.

6. What regulatory processes would your body use if you were trapped by a blizzard in an unheated, uninsulated cabin in the woods (or in a heat wave with no air conditioning)
Answers
Answer:
Shivering and sweating.
Explanation:
A prolonged exposure to extreme cold environment would activate the brain's heat-gain center. Your brain's heat-gain center causes shivering in order to increase our muscle contraction which leads to warming of our body. Increase sweating is the regulatory processes our body use if it experience very high temperature. In order to regulate internal temperature of body, our body remove water which takes up heat with itself to lower th internal temperature.
3. The human body has devised an excellent method to keep the body pH under control. a. What principle underlies the constant pH of human blood, and how does the blood achieve this
Answers
The normal blood pH for adult humans is 7.40, and this pH value is vigorously defended at normal body temperature
Acid base Homeostasis is the method by which body keeps a constant ph
pH is kept under check via different systems
1. Chemical system :bicarbonate buffer system(explained below )
Respiratory component :
2. Respiratory Component: The second line of dense is rapid consisting of the control the carbonic acid concentration in the ECF by changing the rate and depth of breathing by hyperventilation or hypoventilation. This blows off or retains carbon dioxide (and thus carbonic acid) in the blood plasma as required
3.Metabolic component : third line of defense is slow, best measured by the base excess,eand mostly depends on the renal system which can add or remove bicarbonate ions to or from the ECF.Bicarbonate ions are derived from metabolic carbon dioxide which is enzymatically converted to carbonic acid in the renal tubular cells.There, carbonic acid spontaneously dissociates into hydrogen ions and bicarbonate ions.When the pH in the ECF falls, hydrogen ions are excreted into urine, while bicarbonate ions are secreted into blood plasma, causing the plasma pH to rise.The converse happens if the pH in the ECF tends to rise: bicarbonate ions are then excreted into the urine and hydrogen ions into the blood plasma.
Buffers usually consist of a weak acid and its conjugate base; this enables them to readily absorb excess H+ or OH–, keeping the system’s pH within a narrow range.
Maintaining a constant blood pH is critical to a person’s well-being. The buffer that maintains the pH of human blood involves carbonic acid (H2CO3), bicarbonate ion (HCO3–), and carbon dioxide (CO2). When bicarbonate ions combine with free hydrogen ions and become carbonic acid, hydrogen ions are removed, moderating pH changes. Similarly, excess carbonic acid can be converted into carbon dioxide gas and exhaled through the lungs; this prevents too many free hydrogen ions from building up in the blood and dangerously reducing its pH; likewise, if too much OH– is introduced into the system, carbonic acid will combine with it to create bicarbonate, lowering the pH.
Example: Antacids, which combat excess stomach acid, are another example of buffers.

30% of the total carbohydrates for a person on a 2,000 calorie diet will provide if drinking 16 oz of this beverage.
How is 30% 15% in the given table?The table is based on 2000 calories, and one serving is 8 oz.
Thus the question is for two servings.
Which equals 30% carb of a 2k calorie diet.
What are carbohydrates?Carbohydrates are macronutrients that provide energy to our bodies in three ways.Carbohydrate-containing foods are converted into glucose or blood sugar by the digestive system during the digestion process.Thus, we can conclude that option D is the correct option, 30% of the total carbohydrates for a person on a 2,000 calorie diet.

What is tRNA?A form of RNA molecule called transfer ribonucleic acid (tRNA) aids in the translation of a messenger RNA (mRNA) sequence into a protein.
Translation, which creates a protein from an mRNA molecule, uses tRNAs at particular locations on the ribosome. A protein's amino acid composition is determined by codons, which are three-nucleotide mRNA sequences.
Every codon corresponds to a distinct amino acid, and every codon is accepted by a particular tRNA. The three hairpin loops that make up the tRNA molecule's characteristic folded structure give it the appearance of a three-leafed clover.

Answers
Constants never change.
Controls typically don't change or they are done by standard means
(like in an experiment where you water plants with sodas, the plant you use water with is the control)
Dependent variables are the outcome of the experiment. This is the result of changing something.
Independent variables are what you are testing. A independent variable is something that is intentionally altered.
easy way to remember it is that dependent variables depend on what other variables are. so you cant change a dependent variable, but you can change the other variables.

Is it a good idea for humans colonize mars pls real answers :)
Answers
Answer:
I believe yes and no at the same time
Explanation:
If we do end up colonizing Mars, Earth could slowly get better as time goes on, but when we do colonize Mars, wont we just do the same thing we did to Earth?
Answer:
Yes it could be, here are the pros.. Colonizing Mars is one of the most promising backup plans for humanity . Mars is relatively close to our Earth . Colonizing Mars may become possible in just a few decades . Many celebrities support those plans . Many scientists advocate for this kind of backup plan . Extraction of additional natural resources . May help with the search for other life forms . We could learn as global human species . Humanity needs challenges to progress . Knowledge is power . May help to mitigate the overpopulation problem on Earth . Colonizing Mars is an image project . Future generations would be able to adapt quite quickly on Mars . May be a good long-term investment for institutional investors
But there are also some cons.. Colonizing Mars is extremely expensive . It takes a while to travel to Mars ; Lack of water may become a serious problem . Plenty of insecurity involved in this plan . Completely different living conditions . Humans need protective equipment before going outside . It’s freezing cold on Mars . Some people have to make the beginning . May not be justifiable from an ethical standpoint . Colonizing Mars may conflict with religion . Money can be better used to solve our problems on planet Earth . Some scientists believe that efficient live on Mars will not be possible . Quality of life on Mars would be much lower . Rather insecure food supply . Radiation may become a problem . Still unclear if living on Mars is sustainable . We would alter the balance in our universe . Colonizing Mars can be dangerous . Space exploration implies significant pollution . Other life forms may not be welcoming towards us humans . Short-term costs vs. long-term gains
In conclusion, no it would not be a good idea.
