Arrange the steps of the chemical response of a cell to epinephrine in the correct order. 1. production of GTP from GDP 2. conversion of cyclic AMP to ATP 3. activation of a G protein in the cell membrane 4. release of glucose into the bloodstream 5. activation of adenylate cyclase 6. conversion of ATP to cyclic AMP
Answer:
3, 1, 5, 6, 4, 2.
Explanation:
Epinephrine (i.e., adrenaline) is a hormone secreted by the adrenal glands and some neurons. This hormone binds to a type of G protein-coupled receptor called beta-adrenergic receptors. This binding results in the activation of adenylate cyclase and the intracellular production of a second messenger known as cyclic adenosine monophosphate (cAMP), which is synthesized from adenosine triphosphate (ATP). cAMP activates different kinases that phosphorylate specific protein substrates, thereby activating and inhibiting different enzymatic reactions. Finally, this process activates an enzyme called glycogen phosphorylase that breaks down glycogen into glucose which is released in the blood.

Plantae organism that can make its own food and is composed of many cells that each contain a nucleus belongs to which kingdom.
What is Plantae?Apart than some of the earliest cousins of algae, the class Plantae comprises multicellular creatures. They are eukaryotes, which means they have membrane-bound cellular organelles and a nucleus. Around the cell, there is a cellulose-containing cell wall.
Typically, a mature plant has a single, big central vacuole that is bound by a tonoplast (membrane). The reserve food for plants is starch and lipids (oil/fat).
All plants have cells, which contain plastids, double membrane-covered cell organelles. Photosynthetic pigments are present in several plastids (chlorophylls).
Therefore, Plantae organism that can make its own food and is composed of many cells that each contain a nucleus belongs to which kingdom.

Animals, like other life-forms, evolved in the ocean. What made water a better nursery than land for the evolution of animals?
Answer:
The new study is the first to distinguish between bodies of water with low and high levels of oxygen. It shows that poorly oxygenated waters did not support the complex life that evolved immediately prior to the Cambrian period, suggesting the presence of oxygen was a key factor in the appearance of these animals.

Why does the control of blood sugar by insulin show negative feedback?
Select one:
The release of insulin causes sugar levels to increase even more.
Sugar lowers the levels of insulin back to the normal levels.
The release of insulin brings the sugar levels back to normal.
Insulin mixes with the sugar to prevent it from damaging the cells.
Answer:
The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels.

how many molecules are there in 4.00 moles of glucose n2o3
Answer:
2.41 × 10^24 molecules
Explanation:
To calculate the number of molecules of a substance (nA), we multiply the number of moles of such substance (n) by Avagadro's number or constant, which is 6.02 × 10^23.
That is; nA = n × 6.02 × 10^23.
In this question, 4 moles of glucose were given. The number of molecules in 4 moles of glucose is as follows:
nA = 4 × 6.02 × 10^23
nA = 24.08 × 10^23
nA = 2.41 × 10^24 molecules.
explain how the hydrosphere and atmosphere are related.
Answer:
Water circulates in a cycle across the hydrosphere. Clouds gather water, which then falls to Earth as rain or snow. Rivers, lakes, and seas store this water. Then it evaporates back into the atmosphere, restarting the loop.
Explanation:
Answer:
The hydrosphere is the part of Earth were all the water is contained.
The atmosphere is the part of Earth were all the gases are contained.
These two are related because the hydrosphere is inside the atmosphere.
The hydrosphere goes down below sea level, because of several trenches and other holes like the Mariana trench. The hydrosphere also goes around 20 kilometres in the air because of clouds.
write a summary on how super bugs develop resistance to antibodies
Superbugs are strains of bacteria that are resistant to several types of antibiotics. Each year these drug-resistant bacteria infect more than 2 million people nationwide and kill at least 23,000.
When used properly, antibiotics can help destroy disease-causing bacteria. But if you take an antibiotic when you have a viral infection like the flu, the drug won’t affect the viruses making you sick. Instead, it’ll destroy a wide variety of bacteria in your body, including some of the “good” bacteria that help you digest food, fight infection, and stay healthy. Bacteria that are tough enough to survive the drug will have a chance to grow and quickly multiply. These drug-resistant strains may even spread to other people.
Over time, if more and more people take antibiotics when not necessary, drug-resistant bacteria can continue to thrive and spread. They may even share their drug-resistant traits with other bacteria. Drugs may become less effective or not work at all against certain disease-causing bacteria.

Which correctly describes a difference between the male and female
reproductive systems?
O A. Males store gametes in the ovary.
B. Females produce fewer gametes.
C. Females produce gametes every day.
D. Males receive gametes from females.
Answer:
B . Females produce fewer gametes.
Explanation:
The option that correctly describes a difference between the male and female reproductive systems is B. Females produce fewer gametes.
What is a reproductive system?The reproductive system is a collection of organs and tissues that work together to produce, transport, and fertilize gametes (sperm in males and eggs in females) to facilitate reproduction. In males, the reproductive system includes the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and urethra.
Sperm are produced in the testes, mature and are stored in the epididymis, and then transported through the vas deferens and mixed with seminal fluid produced by the seminal vesicles and prostate gland before being ejaculated through the urethra during sexual intercourse. In females, the reproductive system includes the ovaries, fallopian tubes, uterus, cervix, and vagina.
Eggs are produced in the ovaries and are transported through the fallopian tubes, where fertilization can occur. The fertilized egg then implants in the uterus, where it can develop into a fetus. Hormones, such as estrogen and testosterone, play important roles in regulating the reproductive system and maintaining sexual characteristics.

The periodic shedding of the uterine lining usually takes place --
O after menopause
O during pregnancy
O if fertilization does not occur
O before puberty begins
Answer:
before puberty begins
Explanation:
because on your menstrual cycle the blood clots are actually pieces of uterus and that's actually your uterine shedding and it usually starts doing that even before your period begins so it definitely be before puberty begins hope I didn't make the answer to awkward but that's the truth LOL
The periodic shedding of the uterine lining usually takes place before puberty begins. The correct option is D.
Thus, An egg is released from the ovary into the fallopian tube during ovulation, which happens roughly halfway through a woman's menstrual cycle. The uterine lining that was developed to support a potential pregnancy is no longer required if fertilization of the egg by a sperm does not take place.
The uterine lining sheds as a result, causing menstruation, often known as the monthly menstrual cycle. In a typical 28-day menstrual cycle, this shedding typically takes place around 14 days following ovulation.
In females of reproductive age, menstruation is a normal process that lasts until menopause, at which point it ceases. Menstruation is a component of the menstrual cycle.
Thus, The periodic shedding of the uterine lining usually takes place before puberty begins. The correct option is D.
