wiped out multiple rainforestsdisplaced several indigenous tribesruined shelter of endangered speciesYou 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
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 stainA 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.

After completing 10 years of experimentation, a scientist reports a
new scientific theory explaining the movement of sand on beaches.
How do you know that this information is valid?
There were too few years of data.
The initial hypothesis was incorrect.
The problem was not important enough.
Theories develop through repeated experimentation.
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.

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?
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.Which of the following orientation terms have opposite meanings in humans? *

Why do skates and rays have flattened bodies, while sharks are torpedo shaped?a. Sharks are more closely related to the tube-like lampreys than are skates and rays.b. Skates and rays need enlarged pectoral fins to help them stay level in turbulent water, while sharks do not.c. 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.
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.

how and why earth material seperated into layers.
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.

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.
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.

E) It doesn't matter what half-reaction this is coupled with, it will not proceed spontaneously. subunit of ATP synthase causes conformation changes in the
Answer
The correct is A)
Explanation:
A reduction half-reaction occurs in the cathode. The standard cell potencial (Eºcell) is higher than 0 for a spontaneous reaction. According to this, we deduce:
Eºcell = Eºr(cathode)-Eºr(anode) > 0 (spontaneous)
So, Eºr(cathode) > Eºr(anode) for a spontaneous reaction.
Since Eºr(cathode)= 0.80 V, we can say:
A) This half-reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential less than 0.80 V. TRUE
For example: Eºcell = Eºr(cathode)-Eºr(anode)= 0.80 V - (0.75 V)= 0.05 V > 0
B) This half-reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential greater than 0.80 V. FALSE
It is the opposite of A. For a value greater than 0.80 V, Eºcell will be <0 (non spontaneous)
C) This half reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential greater than -0.80 V. FALSE
This sentence is not true in all cases. For example: a reduction potential of 1.0 V is greater than -0.80 V, so:
Eºcell= Eºr(cathode)-Eºr(anode)= 0.80 V - (1.00 V)= -0.20 V < 0
D) It doesn't matter what half-reaction this is coupled with, it will proceed. FALSE, the reduction potential of the anodic reaction must be lower than 0.80 V.

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.
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.
