describe how you would test a sample of powdered milk to see if it contained reducing sugar​

Answers

Answer 1

Answer:

The correct answer is -  Benedict's test.

Explanation:

To test the presence of the reducing sugar in the milk the best test would be Benedict's test with the help of Benedict's reagent or solution which is a mixture of sodium carbonate, copper(II) sulfate pentahydrate, and sodium citrate. It reacts with the reducing sugars and gives a precipitate of cuprous(I) oxide.

R.CHO + Cu(II)(OH)2 ------> R.COOH + Cu(I)2 O + 2H2O

The presence of reducing sugars results in the oxidation of them by copper iron. This forms carboxylic acid and a reddish ppt. of copper oxide turning the color of solution orange, red or brown

Suppose virus A has a viral genome of 19,000 bp, and 10,000,000,000 viruses are replicated in an infected individual in a single day. Assume that a single mutation at a particular location in the virus A genome is needed for virus A to develop antiviral drug resistance to ledipasvir. The mutation can be a transition or transversion mutation. If RNA polymerase introduces an error in 1 of every 10,000 bases synthesized, how long will it take for virus A to overcome ledipasvir therapy and develop resistance? Round your answer up to a whole number of days.

Answers

Answer:

1 day.

Explanation:

From the given information:

The rate of mutation induced by RNA polymerase is:

[tex]\implies \dfrac{1}{10000}= 0.0001[/tex]

Since the genome comprise of 19000 bp;

To complete a single replication, the viral cycle induce: [tex]= \dfrac{19000}{1000}[/tex]

[tex]= 1.9 \ mutation \\ \\ \simeq 2 \ mutation[/tex]

However, in a single day; 10,000,000,000 viruses are reported to be replicated.

Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:

[tex]= \dfrac{10,000,000,000}{2} \\ \\ = \text{5000000000 \ mutations \ in \ a \ half \ day which is half} \\ \\ \text{ the given no of the replicated virus}[/tex]

SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.

The articulating bones that form the joint(s) How the joint participates in mastication (chewing food)

Answers

Answer:

TEMPOROMANDIBULAR JOINTS

Explanation:

The breaking up of food into smaller particles through the combined action of the teeth, muscles and joints is called MASTICATION. This helps to increase the surface area of food to make the enzyme activity easier during digestion.

A joint is a place where two or more bones meet or articulate.The joint involved in mastication( chewing) is called the TEMPOROMANDIBULAR JOINTS (TMJ). This joint is formed by the articulation of the mandible and the temporal bone of the skull.

Structurally TMJ is classified a s a synovial joint because it possesses articular cartilage on the bone surfaces, and a joint capsule that encloses synovial fluid. While functionally TMJ is classified as diarthrosis joint because it can move freely in different planes.

It's synovial classification it is known as a condyloid joint because it consist of an oval-shaped end of one bone fitting into a similarly oval-shaped hollow of another bone to allow angular movement along two axes. This enables it to have the following different movement:

--> mandibular depression,

--> elevation,

--> lateral deviation (which occurs to both the right and left sides),

-->retrusion and protrusion.

The articulating bones that forms the joint include the mandible and the temporal bone

The TMJ participates in mastication by allowing the movement of the mandible while the temporal bone remains in place

Bacteria are sensitive to certain antibiotics like chloramphenicol and streptomycin, which kill the bacteria by interfering with translation through mechanisms that affect the ribosome's ability to function. If a researcher were to culture populations of Archaea and then treat them with either of the previously mentioned antibiotics, what would be the predicted results

Answers

Answer:

Explanation:

Neither antibiotic will have an effect on Archaeon populations because their ribosomes are different from bacterial ribosomes.

The predicted result of this experiment is that Archaea do not show any response towards specific antibiotics.

What are Antibiotics?

Antibiotics may be defined as a type of medication that inhibits the growth of microorganisms and fight against bacterial infections in humans or animals.

Due to the alterations in the structural and functional unit of ribosomes, none of the antibiotics causes any significant effect on the body of Archaea.

What weakens hurricanes when they reach the Atlantic Ocean

Answers

colder water churned up from beneath the sea surface by the hurricane can cause the hurricane to weaken.

These storms diminish and disintegrate once they cross over land or across cold water, losing contact with the hot water that gives them strength.

What are hurricanes?

A spiral arrangement of thunderstorms that produce torrential rain and squalls, a low-pressure center, and powerful winds are the characteristics of a tropical cyclone, a fast revolving storm system.

A tropical storm that has sustained winds of 74 mph or greater is referred regarded as a hurricane.

A storm's eye typically measures 20 to 30 miles in width and can reach distances of 400 miles.

Storms can be dangerous because of their torrential downpours, strong gusts, and storm surges.

Because they are no longer being fueled by the energy from the warm ocean waters, hurricanes typically lose strength when they make landfall.

Thus, these are the factors that weakens hurricanes when they reach the Atlantic Ocean.

Explanation:

In genetics, phenotype refers to the observable characteristics/ traits in a particular organism. An individual phenotype results from the interaction of genes and the environment. Moreover, in diploid (2n) species, an organism is heterozygous for a given trait when it carries two different gene variants or 'alleles' of the same gene. These two alleles are received from both parents, i.e., one allele from one parent and another one from the other parent. Finally, an organism is homo-zygous for a given trait when it carries two identical alleles of the same gene.
