Answer: Height

Explanation: IV diverse stickiness levels, DV height CV, same tree type(redwood), time (12 weeks) – tree left external I typical conditions is likewise viewed as a benchmark group as it encounters no mugginess change.

The various variables can be grouped as  :

Independent variable; Humidity levels

Dependent variable; Heights of the trees

Controlled variable ; Green house

The independent variable is the variable that not affected by the change in other variables, it determines the outcome of an independent variable in an experiment. and from our question the independent variable is the different humidity levels inside the Greenhouse

Dependent variable is the measured variable in an experiment which is primarily dependent on the Independent variable, it can be likened to be  effect/result  of an experiment ; height of the trees

A controlled variable is a variable that is held constant during an experiment because it doesn't have a direct importance on the aim of the experiment, but it can affect the outcome if not controlled ; Green house

Hence the independent variable = Humidity levels, Dependent variable = height of trees and the controlled variable = green house

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.

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.

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.

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.

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.

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.

Answer:

Scientists try to figure out how the natural world works. In doing so, they use experiments to search for cause and effect relationships. Cause and effect relationships explain why things happen and allow you to reliably predict what will happen if you do something. In other words, scientists design an experiment so that they can observe or measure if changes to one thing cause something else to vary in a repeatable way.

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.

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.

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.
