what is the most important nutrient for energy?​

Answers

Answer 1
The three main nutrients used for energy are carbohydrates, protein, and fats, with carbohydrates being the most important source. Your body can also use protein and fats for energy when carbs have been depleted. When you eat, your body breaks down nutrients into smaller components and absorbs them to use as fuel.

You use the Gram staining procedure to stain an L-form bacterium (a bacterium that lacks a cell wall). What color will the bacterium be after the staining procedure is finished

Answers

Answer:

Pink

Explanation:

A microbiologist named Christian Gram invented the gram staining technique, which aims at using a colored substance (crystal violet in colour) called GRAM STAIN to identify bacteria cells. Using the gram staining procedure, bacteria cells are classified as either Gram-positive or Gram-negative.

Gram positive bacteria are those bacteria types that retain the crystal violet color of the gram stain due to the peptidoglycan content (high) of their cell wall. Hence, they appear PURPLE after the procedure. They don't get decolorized after the procedure.

On the other hand, Gram-negative bacteria does not retain the crystal violet color of the Gran stain (gets washed off) because they lack a peptidoglycan-containing cell wall. During the gram staining procedure, the gram-negative bacteria gets bleached using an alcohol, hence, is recolorized by another dye called SAFRANIN, which makes the gram-negative bacteria appear PINK.

The bacterium will attain pink color after staining is finished.

Gram stain

A test, which checks for bacteria at the location of a suspected infection like the lungs, throat, genitals, or in the wounds of the skin.

In the sample, when the stain combines with bacteria it will either turn pink or red or stay purple.

If the bacteria remains purple, they are considered as Gram positive.

In the L-form of bacteria, as they lack cell wall, they attain pink color, that is, they attain safranin dye.

In the L-form of bacteria, as they are devoid of cell wall, the decolorization of crystal violet takes place with ethanol, and then it attains pink color of safranin.

Thus, the L-form of bacteria will attain pink color.

Theories develop through repeated experimentation.

Answers

Answer:

Theories develop through repeated experimentation.

Explanation:

The correct answer would be that theories develop through repeated experimentation.

A theory is internally consistent and is only arrived at after several independent experimentation based on the same phenomenon. That is, when a scientist reports a findings, the reports must have been widely tested by different researchers using the same experiment and arrive at similar findings before they can become a theory.

Hence, the information on the theory explaining the movement of sand beaches is valid because the experiment must have been repeated by several independent researchers and similar results must have been obtained before the theory is arrived at.

How long does it take for half of the carbon-14 to convert back to nitrogen? Radioactive decay will cause carbon-14 to eventually become what? Why is carbon dating only useful for formerly living organisms?

Answers

Answer:

The correct answer is -

- 5,730 Approximately

- carbon-12 isotopes

- carbon-14 decays at this steady rate

Explanation:

Half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years so the Carbon-14 has a half-life of 5,730 Approximately .

As Carbon-14 unstable it is considered a radioactive isotope of carbon, carbon-14 will inevitably decay back to carbon-12 isotopes.  

Radiocarbon dating is a method utilized by researchers to learn the ages of organic examples. It very well may be utilized on objects as old as around 62,000 years.  

Radiocarbon decays gradually in a living being, and the amount lost is ceaselessly renewed as long as the living being takes in air or food. Since carbon-14 decays at this steady rate, an estimate of the date at which an organism died can be made by estimating the measure of its residual radiocarbon.

A medical company has developed a product that contains an enzyme that helps lactose intolerant individuals digest the sugar lactose, which is found in many dairy products. The medication should be stored at a temperature that has a lower rate of reaction than in the body. The company would like to know the ideal temperature at which to store this new medication. During a controlled experiment, the following data is collected: Based on the data, at which temperature would you suggest the pharmaceutical company store the medication and why? A.The medication should be stored at room temperature because the enzyme has most effectively catalyzed the reaction at this temperature. B.The medication should be stored at a cold temperature because the data shows that the enzyme action slows down at colder temperatures. C.The medication should be stored in hot water because the enzyme denatures at higher temperatures. D.The medication should be stored in warm water because the heat from the water sped up the rate of the reaction to its optimal level.

Answers

Answer:

B.The medication should be stored at a cold temperature because the data shows that the enzyme action slows down at colder temperatures.

Explanation:

The most suitable temperature to store a medication is the cold temperature because the activity of enzyme is slower at lower temperature. Higher temperature cause denaturation of enzymes while at 37 degree Celsius temperature, the enzyme activity is maximum so both high temperature and room temperature is not good for the medication whereas temperature less than 5 degree Celsius is the best to store medication.

how and why earth material seperated into layers.​

Answers

Answer:

After several million years, the Earth separated into several layers. Iron, nickel and other heavy metals mostly settled to the core; lighter elements remained in the mantle around the core. The lightest elements, such as oxygen and silicon, floated to the top and cooled, forming a solid crust. Because the Earth was not completely liquid, the layering process was uneven; pockets of heavy elements remained in the crust.

The electrons in a bond with electrons held tightly by oxygen:
a. are completely transferred from one atom to the other.
b. are loosely held between the two atoms forming the bond.
c. give rise to positive and negative partial charges.
d. are equally attracted by both atoms forming the bond.
e. give rise to full electrical charges.

Answers

Answer:

C). Give rise to positive and negative partial charges.

Explanation:

As we know, electronegativity is characterized as the ability of an atom or molecules to attract electrons and form bonds, and Oxygen is one of the electronegative elements in the periodic table. The other electronegative elements are Fluorine and Nitrogen. Thus, the oxygen would be able to 'attract electrons towards it' and this will lead to having a partial negative -ve charge on oxygen itself and partial positive +ve charge on the other atom. Thus, option C is the correct answer.

A. It is carried out by temperate phage.
B. It is restricted to those genes on either side of an integrated prophage.
C. The phage genome retains the full complement of phage genes.
D. All of the choices are correct.

Answers

Answer:

C. The phage genome retains the full complement of phage genes.

Explanation:

Transduction refers to the mechanism where a bacteriophage (i.e., a virus capable of infecting bacteria) transfers exogenous DNA from one bacterium to another. During transduction, the bacteriophage coopts the host (bacterial) cellular machinery in order to replicate their own genetic material, for which the virus needs to integrate its own genetic material into the bacterial genome. Specialized transduction refers to the genetic mechanism where a particular set of bacterial genes (donor genes) is passed to another bacterium. This process occurs when a bacteriophage genome that is inserted into the bacterial genome (also known as prophage) excises imprecisely and then adjacent donor genes are included in the excised genetic material.

An atom of a certain element has 36 protons, 36 electrons, and a mass number of 84, At
room temperature this element is a very stable gas. How many neutrons are in this atom?

Answers

Answer:

48

Explanation:

Atomic number is equal to how much electrons there is (the number of protons is equal to the number of electrons)

To find the number of neutrons, one have to subtract the atomic number from the atomic mass.

i.e: 84-36=48

The atom of the element contains 48 neutrons.

SUBATOMIC PARTICLES:

In an atom, there are three subatomic particles namely: neutron, proton and electron. The proton is the positively charged part of the atom, the electron is the negatively charged part while the neutron is the neutral part.

HOW TO CALCULATE MASS NUMBER:

The mass number of an element can be calculated by adding the number of neutrons and the protons, which is the atomic number.

This means that the number of neutrons can be calculated by subtracting the number of protons from the mass number of the element. That is;

No. of neutrons = mass no. - no. of protons

No. of neutrons = 84 - 36

No. of neutrons = 48

Therefore, the atom of the element contains 48 neutrons.

The Australian wildfire are by far the worst wild fire seen in decades, with the large swaths of the country devastated since the fire season began in late July. At least 28 people have died nationwide and around 3,000 homes have been destroyed or damaged. The effect of the wildfire are devastating because some of their water has and might be contaminated due to the debris. The effects of the fires on the forests and ecosystems are uncanny, there was about 8.9 million acres are scorched. Then the estimated period of time is about 4,000 years before the forest are to be recovered due to the recovering the native and rare species that are unique to the original forest. The effect are brutal and we should just imagine the cost of rebuilding the houses an land is about 100 Billion. The cause of the deadly fires were fueled by a combination of extreme heat, prolonged drought and strong winds. The record breaking temperatures lasted over 3 months and the wind speeds were recorded at about 60 miles per hour. There have been downpours in the states of Victoria, New South Wales and Queensland, which have all been badly hit by the bush fire crisis. Since then all wildfires in Australia have been extinguished though there hasn’t been much change in the scorched forest.

Skates and rays exchange gases across their skin and thus require a high surface-area-to-volume ratio, while sharks use gills to respire.d. Sharks are streamlined for active swimming at mid-depths, while skates move about mostly on the ocean bed.

Answers

Answer:

D.Sharks are streamlined for active swimming at mid-depths, while skates move about mostly on the ocean bed.

Explanation:

Sharks are known to be active off the bottom of oceans and in mid depth which has a high salinity and the streamlined body helps it to move in this kind of saline conditions.

The Skates however don’t move much and are always at the ocean bed.

This is why Sharks are streamlined for active swimming off the bottom, while skates have flat bodies move about mostly on the ocean bed is the right choice.

temperatures. Which of the following would best help the researcher determine
how well the enzyme is working? (D.O.K 2)

Answers

Answer:

This question lacks options, but the answer is TEMPERATURE

Explanation:

In an experiment, two common variables are used: independent and dependent variable. The independent variable is the variable that is changed or manipulated by the experimenter in order to effect a response in the dependent variable.

The dependent variable, on the other hand, is the responding variable or the variable that is measured by the experimenter. Note that, It is dependent on the independent variable.

In this question, the independent variable is DIFFERENT TEMPERATURE that the enzymes were exposed to because it is what is being changed by the researcher. The dependent variable is the EFFECTIVENESS OF THE ENZYME, which is dependent on the temperature it is exposed to.

Hence, how well an enzyme works (effectiveness) is determined by the TEMPERATURE
