What happens when starch, a polymer of glucose, is dissolved into solution?

Answers

Answer 1

Answer:

Answer:The starch polymer remains unchanged after dissolving in water, but some of the starch polymers dissolve while others hydrolyze into glucose monomers, influenced by temperature and pH.

Explanation:

Answer 2

Answer:

Final answer:

When starch is dissolved in a solution, it undergoes hydrolysis facilitated by the enzyme amylase to break down into maltose units. The solute concentration of the solution increases and the presence of starch can be tested for with an iodine solution.

Explanation:

When starch, which is a polymer of glucose, is dissolved in a solution, it breaks down into smaller units called maltose due to the hydrolysis reaction. The process is usually facilitated by an enzyme, such as amylase, which facilitates the reaction by providing an alternative reaction pathway with lower activation energy. The liberation of glucose molecules in the solution increases the solute concentration of the solution and can be easily tested for with iodine solution, which would turn from yellow-brown to blue-black upon detection of starch.

Introducing the gene for bovine growth hormone into the eggs of pigs is an example of a process called

Answers

The answer is germline gene therapy.

The gene therapy is the process which aim is to introduce the gene for the desired protein into cells in order to make desired protein or to compensate for abnormal genes. If the gene for the desired protein is introduced into the gamete cells (eggs or sperms), then the gene therapy is called germline. The example is introducing the gene for bovine growth hormone into the eggs of pigs. This way the change is heritable and can be passed down to the next generation.

Imagine that a brown horse and a whitehorse cross to produce an offspring whosecoat is made up of some brown hairs and somewhite hairs. Which pattern of dominance is thisan example of?

Answers

Codominance.

Because in the codominance, both the traits of the brown hair and white hair is expressed. So it carries both the traits, regardless of whether it is recessive or dominant.

Bugs effecting unimmunized children: respiratory

Answers

Unimmunized children are susceptible to respiratory infections caused by various bugs, including viruses and bacteria, due to a lack of vaccination protection.

Unimmunized children are more vulnerable to respiratory infections caused by a variety of pathogens such as viruses and bacteria. Vaccinations play a critical role in providing immunity against certain respiratory illnesses, including influenza, pertussis (whooping cough), measles, and others.

When children are not immunized, they lack the specific protection conferred by vaccines, making them more susceptible to infections that can affect the respiratory system. Respiratory infections can lead to complications, compromise overall health, and contribute to the spread of infectious diseases within communities. Immunization programs are essential for preventing the occurrence and transmission of respiratory bugs among unimmunized children, promoting individual and public health.

How would the contractile vacuole of a freshwater amoeba respond if the organism was placed in seawater?with more contractions
with fewer contractions
the contractions would suddenly cease
with the same frequency of contractions

Answers

Correct answer: B). With fewer contractions

The main function of a contractile vacuole is to maintain the sufficient amount of water in the protoplasm of the cell. For the freshwater amoeba contractile vacuole is needed to pump water and maintain a osmoregulation.

But when it is kept in sea water, more contraction is required to expel the water out of the cell in order to make the environment inside amoeba same as of sea water.
