The pH range over which an indicator alters the color defines the transition interval of an indicator.
What do you mean by Transition?A Transition may be defined as a condition or process where one state of a compound changes into the other.
A Transition interval is a point where the color of indicators may change. For example, Phenolphthalein changes pink from colorless at a pH of 8-10. So, this point is called the transition interval.
Therefore, the pH range over which an indicator alters the color defines the transition interval of an indicator.

3. What would be an example of deposition?
Answer:
frost
Explanation:
Frost is the deposition of water vapour from humid air or air containing water vapour on to a solid surface. Solid frost is formed when a surface, for example a leaf, is at a temperature lower than the freezing point of water and the surrounding air is humid.
In sub-freezing air, water vapour changes directly to ice without first becoming a liquid. This is how frost and hoar frost form on the ground or other surfaces. Another example is when frost forms on a leaf.

The san marcos salamander, eurycea nana, is a light reddish-brown translucent salamander about 2–5 cm in length. E. Nana is found only in spring lake and a portion of the san marcos river. Which human activity would most likely decrease the ability of the salamanders to survive?.
Human activity would likely decrease the salamanders' survivability is the growth of cities, which has led to greater use of water by people and increased problems of water pollution and sludge buildup.
What leads to the disappearance of the species?Reducing the flow of water from springs is the biggest threat to the survival of Salamandra San Marcos and other animals and plants dependent on the springs. The growth of cities has led to greater use of water by people and has increased problems with water pollution and sludge buildup. The introduction of non-native species is also a threat because they can destroy aquatic vegetation, attack endangered animals or compete with them for food.
With this information, we can conclude that human activity would likely decrease the salamanders' survivability is the growth of cities, which has led to greater use of water by people and increased problems of water pollution and sludge buildup.

Multiple Choice Sigma factor: the protein that binds to bacterial promoters to initiate transcription Insulin: the protein that tells cells to uptake glucose Keratin: the protein that gives cells structure Glucose transporter: the protein that allows glucose into cells ATP-synthase: the protein that produces ATP from ADP and P
Answer:
ATP-synthase: the protein that produces ATP from ADP and P
Explanation:
Proteins have diverse functions. Enzymes are very specific type of proteins with catalytic activity, help run reactions, and help with metabolism.
ATP-synthase is an enzyme in electric transport chain which allows us to make ATP using the electrochemical gradient in mitochondria.

3. In the Pacific Ocean, there is a plate boundary between two tectonic plates: the Pacific Plate, which contains some of
the oldest oceanic crust on Earth, and the Mariana Plate. The Mariana Trench, the deepest oceanic trench on Earth,
is located at this boundary. Nearby, there is an arc of volcanic islands called the Mariana Islands. Based on this
information, what type of plate boundary is this? How do you know?
Ocean trenches are long, narrow depressions on the seafloor. These chasms are the deepest parts of the ocean—and some of the deepest natural spots on Earth.
There are different types of plate boundaries based on the movement of tectonic plates. The plate boundary in which a line of volcanic islands are present is called convergent plate boundary.
What is plate boundary?Plate boundary is the inter-region between two tectonic plates. The magma in the crest when undergo convection process and flow of this heated magma causes the movement of tectonic plates.
Based on the movement and sliding of the plates above the other there are three types of plate boundaries namely, divergent, convergent and transform plate boundaries.
Divergent plate boundaries originates when the plates moves apart these type of plate boundaries have the volcanic activities and shallow earth quake.
Convergent plate boundaries are where, the plates are moving edge to edge manner each other manner and buckles up to mountain. Convergent plate boundaries create the a chain of volcanoes parallel to the plates.
Transform plate boundary is created by plates sliding past each other which forms no volcanoes. Hence, the volcanic islands are in convergent plate boundary.

Which property of water causes the space between molecules to ice
Answer:
In ice crystals, their hydrogen bonds link them together like acrobats, stacked one on top of the other, with their arms and legs outstretched. This provides more space between the molecules in the crystal structure of ice than the molecules of liquid water. As a result, ice is less dense than the liquid form

3. A cell with 10 chromosomes undergoes mitosis.
(a) How many daughter cells are created:
Answer:
In a cell with 10 chromosomes undergoes mitosis, the result are 2 daughter cells each with 10 chromosomes
Explanation:
Cells have the ability to reproduce or replicate through 2 processes:
Mitosis
Meiosis
Mitosis differs from meiosis because the final result is always
2 daughter cells
The daughter cells are identical to the mother cell and this includes the same number of chromosomes
This means in mitosis 1 cell with 10 chromosomes leads to two identical cells each with 10 chromosomes.
