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.

(1) During the Spanish-American War, U.S. soldiers were supplied with tin cans containing decayed meat. (2) Due to a lack of food safety standards, vendors in the 1800s often sold food that would not today be considered fit for people to eat. (3) Store-bought butter was often stale and mixed with gelatin, fat, and even mashed potatoes. (4) To improve the color of milk from diseased cattle, dairymen sometimes added molasses, chalk, or plaster of Paris. Which sentence is the point of the argument?
Answers
Answer:
It will be 2.
Explanation:
It is the start and introduction to the Arguement.
The point of the argument is the lack of food safety standards in the past, as highlighted by sentence (2) which directly mentions the sale of unfit food. It underscores issues from the Spanish-American War to the broader historical context of food processing.
The point of the argument in the given sentences is that food safety standards in the past were inadequate, leading to the consumption of contaminated and adulterated foods. Sentence (2) articulates this point directly by stating that vendors sold food not considered fit to eat by today's standards. Historical context shows that during times of war and industrialization, there was often a compromise on the quality of food, which was processed in unsanitary conditions or adulterated to make it seem more appealing. Troops during the Spanish-American War faced similar issues with contaminated supplies, which sometimes had dire health consequences. At the same time, the mass production of food using industrial methods and the necessities of war sometimes led to improved access to various foodstuffs, even if the quality was compromised.
Hence, the correct answer is (2) Due to a lack of food safety standards, vendors in the 1800s often sold food that would not today be considered fit for people to eat.

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.
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.

The Langerhans cells in the pancreas secrete the polypeptide hormone insulin, which has a hypoglycemic impact. The function of the pancreatic hormone glucagon is to promote the conversion of glycogen to glucose.
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.
Therefore, the Langerhans cells in the pancreas secrete the polypeptide hormone insulin, which has a hypoglycemic impact. The function of the pancreatic hormone glucagon is to promote the conversion of glycogen to glucose.
