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:

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.

Plz Mark me as brainliest

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:

HOW TO CALCULATE MASS NUMBER:

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

No. of neutrons = 84 - 36

No. of neutrons = 48

Matter is anything that has mass or takes up space (Volume). Matter is made of elements. Elements such as carbon dioxide or gold. An atom is the smallest unit of matter. Elements are made of atoms. Atoms are what chemically makes an element. :) Hope she gets her phone!

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

d I wouldn't say dropping out is the best answer, but I do know that come colleges/universitys offer major changes. I would see if yours offers that option. I'm also terrible at time management and movitivation. I know it doesn't sound like much fun, but I normally have a study day that I dedicate to studying. Last year it was Sunday, since I didn't have school and I'm already home with church. But this year I've been using monday and thursday as my study days.

The answer to the question is D as the purpose for a control group is to be a comparison to the experimental group (the group that is a part of the experiment)

Answer:

D

Explanation:

an example is a person who wants to test if a particular pill makes people run faster. He gets a control group and a test group. After observing the 2 groups he compares the control group to the test group. So control groups are used for comparison to see if the hypothesis is correct or it is just a mare assumption or coincidence

Answer: e. Hydroxyproline

Explanation: Osteogenesis imperfecta is a systemic heritable disorder of connective tissue whose cardinal manifestation is bone fragility - i.e. it is characterized by brittle bones that easily fracture. Hydroxyproline employed in radioactive labeling would not result in labeled collagen because it is not incorporated per se during the synthesis of collagen.

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.

Explanation:

Answer: number 2

Explanation:

The one that correctly describes one result of this heating pattern is Atmospheric and oceanic currents distribute heat from the tropics to the poles. The correct option is 2.

The atmosphere is the outer covering of the earth. It is a layer of gases around the earth. There are different types of atmosphere. They contain different types of temperature, pressure, and gases.

The equator of the earth is at the center of the earth. They have normal temperatures there. At the poles, there is low temperature because sunlight is less there. But with the changing climate of the earth, the warming is increasing and the sun.

Thus, the correct option is 2. Atmospheric and oceanic currents distribute heat from the tropics to the poles.

#SPJ2

Answer:

See the answer below

Explanation:

The size of a pure substance has no effect on its density.

The density of a pure substance which is the ratio of the mass and the volume of the substance is constant. Mathematically, the density is expressed as:

    Density = [tex]\frac{mass}{volume}[/tex]

This means that for every increase in the mass of a pure substance, the volume will increase measurably and vice versa. Under normal conditions, it is practically impossible to increase the mass of a substance without increasing the volume of the substance. It is also not possible to increase the volume of a substance without increasing the mass of the substance.

Hence, the density will always remain constant irrespective of the size of the substance.

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.

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:

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
