In the lab activity, you will use a chemical called a pH indicator that changes color as the pH of a
solution changes. If you added a pH indicator to two different solutions and they both turned the
same color, what would this tell you about the pH of each solution?
ph indicator is used to find the acidic or basic nature of a mixture.
there is a range of colours from red to blue
red colour indicates that solution is acidic and blue colour indicates that solution is basic
if two solutions have same colour that means they also have same ph value

why is it difficult to farm in tilted/inclined landscapes?
Answer:
Farming can lead to the loss of natural habitats.This is destroying natural habitats and changing the very nature and look of our rural landscape.
hope it helps
It is difficult to farm in an incline landscape because initial cost is high, high operational cost, Limited crops can be grown. Thus, due to these following reason, inclined farming becomes difficult.
What is vertical farming?Vertical farming is a practice of growing crops on a hilly or incline land.
However, it may have some disadvantages like high operational cost, high labor cost, only a limited number of crops can be grown.
Hence, due to these reason, tilted farming is difficult.

Los animales toman del medio los materiales necesarios para sus actividades vitales. Estas funciones la realizan: A. El aparato circulatorio. B. El aparato circulatorio, digestivo y respiratorio. C. El aparato respiratorio. D. El aparato respiratorio y circulatorio.
Answer:
C. El sistema respiratorio.
Explicación:
El sistema respiratorio es un tipo de sistema en el que los animales toman del medio ambiente los materiales necesarios para sus actividades vitales. Los pulmones son el órgano principal del sistema respiratorio en el que el gas de oxígeno entra al cuerpo y se almacena en los pulmones a través de la inhalación. La hemoglobina que extrae el gas de dióxido de carbono de la célula lo desecha en los pulmones y carga el oxígeno necesario para el proceso de respiración. El dióxido de carbono se elimina de los pulmones mediante la exhalación.

Explanation:
Quade is studying for an exam, which will cover neurons and action potentials. He has drawn a diagram that shows the segments of an axon, and he has noted that every time a segment fires, the _____ flood in from the outside of the cell, while the prior segment returns to its resting potential. Please choose the correct answer from the following choices, and then select the submit answer button.
Answer: positive sodium ions
Explanation:
This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.
The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.
Many of the D-amino acids found in nature have been discovered in bacterially produced peptides that have antibiotic properties. Bacteria secrete these peptides into their environments to kill competitor bacteria and thereby gain a selective advantage. Given your answer to part (a) of this question, what potential advantages might D-amino acids confer to a secreted peptide toxin
Answer: D-amino acids are less likely to be recognized by proteolytic enzymes thereby they are not degradated.
Explanation:
Peptides are a type of polymers formed by joining several amino acids by means of peptide bonds. They are responsible for a large number of important cellular functions for the organism. Amino acids are thus the monomers that make up peptides and consist of an amino group (-NH2) at one end of the molecule and a carboxyl group (-COOH) at the other end.
Antibiotics are chemical substances produced by a living being (although they can also be synthetic derivatives made in laboratories), which kill or prevent the growth of certain kinds of sensitive microorganisms and are generally drugs used in the treatment of bacterial infections.
All amino acids, except glycine, are stereoisomers which means that there are nonoverlapping mirror images of their structure. These are labeled L (left-handed) and D (right-handed) to distinguish mirror images. A mirror image, for example, compares a right foot with a left foot. They are similar, but not exactly the same, they are like mirror images of each other. However, we could not, for example, put a right shoe on a left foot and vice versa. The same analogy applies to stereoisomers, they are similar but not superimposable, which means that not all compounds will act in the same way in an L or D molecule. For some reason, the amino acids that make up the proteins in human bodies are all L-amino acids.
To distinguish an L-amino acid from a D-amino acid, we must look at the α-carbon, which has four substituents forming a tetrahedron. then we must identify the hydrogen bonded directly to this carbon. In this way they are numbered and following the numbering order, they are classified as L or D.
Bacteria that secrete D amino acids kill other bacteria in the environment that might compete with them for resources, because they have antibiotic properties. These D amino acids are not usually recognized by proteolytic enzymes in organisms that degrade peptides or proteins. So the amino acid remains in the environment fulfilling its function, which is an antibiotic function to fight against other bacteria. Peptide toxins also fulfill this function, however, if they are destroyed by proteases.
