Answer: On Gizmo the answer is Yellow.

Explanation:

Answer 2
Final answer:

The color of the water in tube A after 24 hours will be yellow.

Explanation:

The color of the water in tube A after 24 hours would be yellow.

Bromothymol blue is an indicator that changes color based on the pH of a solution. In the presence of carbon dioxide, it turns yellow. Since the two snails and two Elodea sprigs undergo respiration, they release carbon dioxide into the water, causing the color change from blue to yellow.

Therefore, the correct answer is Option B. Yellow.

Which of the following would cause only a chemical change with a sugar cube

Answers

Answer:

Which would cause only a chemical change in a sugar cube is heating the sugar cube with acid.

Explanation:

The complete question is:

Jolene wants to experiment with sugar cubes. Which of the following would cause only a chemical change with a sugar cube

Burning the sugar cube with a matchstick .Crushing the sugar cube and dissolving it in water .Heating the sugar cube with acid.

The addition of acid to sugar (sucrose) is a known reaction that produces the chemical change of this carbohydrate into carbon, by a process of dehydration.

In the reaction of dehydration of sucrose with sulphuric acid - which is exothermic - the acid extracts water from the sugar molecule, producing gases, such as CO₂ and SO₂, which consumes the acid and converts the sucrose into carbon. The chemical reaction is:

C₁₂H₂₂O₁₁   +    H₂SO₄    +   1/2 O₂  ----------→ 11C + CO₂ + 12H₂O + SO₂

Sucrose + Sulfuric Ac. + Oxygen → Carbon + Carbon dioxide + water + sulfur dioxide.

This reaction involves only a chemical change of the sucrose, when converted into carbon.

Viruses are sometimes triggered into an active state by overexposure to sun, sickness or stress

Answers

Answer:

True

Explanation:

True because bacteria multiplies in the heat more rapidly

Final answer:

Viruses can remain dormant or become activated by stress, leading to a range of diseases, including cancer. They are treated with antiviral drugs and vaccines but can sometimes resist treatment by mutating or evading the immune system.

Explanation:

Viruses are known to cause a wide range of effects in host organisms, and certain environmental factors like overexposure to sun, sickness, or stress can trigger them into an active state. This active state can lead to abnormal growth of the cell or cell death, and sometimes, viruses lay dormant for extended periods without causing noticeable symptoms. When activated, some viruses are associated with serious diseases, ranging from the common cold to more serious ailments like meningitis and cancer. In the latter, viruses such as oncoviruses contribute to cancer by inactivating tumor suppressor proteins, leading to uncontrollable cell growth. Treatment for viral diseases includes antiviral drugs and vaccines, although some viruses can evade immune responses or develop drug resistance.

So how do we get chickens with white and black spots? Shouldn’t they be only white or black?

Answers

Answer:

Codominance

Explanation:

This is an example of codominance.

Basically with this type of genetics, both alleles for that trait, in this case feather color, are dominant. This means that both will appear in the phenotype, instead of a dominant phenotype overshadowing a recessive phenotype.

Here, the two dominant alleles are the one that governs white pigment and the one that governs black pigment. Since codominance is occurring, we see a speckled chicken instead of just an entirely white one or an entirely black one.

C. They are ectotherms.
D. They time their reproduction so that eggs hatch during the winter.
E. They are able to fly when disturbed.

Answers

A. They live in the polar regions of the Northern and Southern Hemispheres.

Final answer:

Penguins can be found as far north as the Equator, with the Galapagos penguin living near that region (option B). They are not ectotherms but endotherms, and they do not fly as they are flightless birds who are adapted for swimming and diving.

Explanation:

Of the options provided about penguins, B. They can be found as far north as the Equator is true. Penguins primarily live in the Southern Hemisphere, particularly in Antarctica, though not exclusively so. One species, the Galapagos penguin, lives near the Equator. Penguins are endotherms (warm-blooded), which allows them to maintain a stable body temperature despite environmental fluctuations. Therefore, it is incorrect to say they are ectotherms. Regarding their breeding habits, many penguin species time their reproduction so that the chicks are hatched and reared during the warmer months when food is more abundant, not in the winter. Finally, penguins are flightless birds, so they cannot fly when disturbed or under any circumstance. They are well-adapted to swimming and diving instead.

What is an Insulin Hormone?

Insulin primarily a peptide hormone that is secreted by the islets of the pancreas of Langerhans cells. It regulates carbohydrate, lipid, and protein metabolism, facilitates cellular glucose uptake, and promotes cell division and proliferation via its mitogenic effects.

Following a meal, carbohydrates decompose to produce glucose, a sugar that serves as the body's main source of energy. After then, glucose enters the bloodstream. In response, the pancreas produces insulin, allowing glucose to get into the body's cells and fuel them with energy.
