Answer:it changes colour
Explanation:
When blood passes through the lungs, the hemoglobin absorbs oxygen from the air we breathe and turns bright red. Our heart then pumps this blood all over the body. When it reaches its destination, the oxygen is released from the hemoglobin, and the hemoglobin turns a darker red-brown.

What is the process by which cells become differentiated?
Answer:
Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.
Answer: Cellular differentiation
Explanation:
The muscular system and the skeletal system are a few of the body systems that work together to form a more complex organization known as a cell a tissue an organ system an organism

The definition of manipulated variable ?
A manipulated variable is an independent variable subject to the changes of an experiment to analyze its effect on a dependent variable. Simply put, the variable is modified to assess its influence over the experiment’s overall result. It’s called “manipulated” because it’s the one you can change. In other words, you can decide ahead of time to increase it or decrease it. In an experiment you should only have one manipulated variable at a time.

Which of the following is not a characteristic of an industrial society? a. Moves from place to place following resources b. Uses new sources of energy c. Increases pollution d. Uses complex tools and systems
Answer: Option A.
Moves from one place to another following resources.
Explanation:
Industrial society does not move from one place to another because it is a society that involves the use of technology in the production of foods and services to support large population and use of high labour.
An industrial society does not move from one place to another rather they are situated within a geographical location and uses new sources of energy, complex tools and systems and increases pollution which is due to Advent of technology .
Answer:
a. Moves from place to place following resources

Name two ways that atoms can combine to become more stable in compounds
Answer:wo processes by which elements can combine to form stable compounds are transferring electrons from one atom to another (ionic compounds) or by sharing electrons (covalent compounds).
Explanation:
i had that question before:)
Answer:
Covalent bonding and Ionic bonding.
Covalent bonding is when atoms share electrons in order to form a stable electron arrangement. The two positive nuclei are attracted to the positive shared electron which holds the molecule together.
Ionic bonding is a giving and accepting of electrons between a metal and non metal. A metal will give the non-metal one or more electrons in order for both to form a stable electron arrangement.
Explanation:
Do protists (amoeba, Euglena, Paramecium) use similar structures to move? Explain.
Answer:
Most protists move with the help of flagella, pseudopods, or cilia. Some protists, like the one-celled amoeba and paramecium, feed on other organisms. Others, such as the one-celled euglena or the many-celled algae, make their food by photosynthesis. ... Theyuse pseudopods to move away from bright light or to trap food.
Within the protist kingdom, organisms have developed very similar structures that are used to move around the environment.
The protist kingdom is primarily comprised of very small, single-celled organisms. Among the vast number of organisms that make up this kingdom are algae and amoebas. Over the course of history, these organisms have evolved very similar means of mobility.
Within the protist kingdom, most of the organisms move with one of the structures:
CiliaPseudopodiaFlagellaThese three structures used by protist to move are very similar in that are all structural extensions on the exterior limit of a cell. Though clear differences exist in the number or other uses of these extensions, it is clear that all of the members of this kingdom have evolved similar means of mobility.

Are flowers naturally rainbow colored? Please describe how the store can
have a rainbow colored plant (using the terms xylem or phloem.)
Answer:
Answer in explanation
Explanation:
Capillary action: Inside the stem, there are tube-like transport tissue, called xylem, that brings water and nutrient to different parts of the plant. Water molecules are attracted to the surface of the xylem cells by weak electrical attractions. This sticky property is called adhesion. Water automatically moves up the xylem due to adhesion and the resulting movement is called capillary action1.
Cohesion: Water molecules are not only attracted to the surface of xylem (adhesion), but they are also attracted to one another. This property is called cohesion. Because of cohesion, water molecules fill the column in the xylem as they move up and act as a continuous stream of water.
Transpiration: Water evaporates from the plant through transpiration. As water evaporates in the petals or any part of the plant exposed to air, a negative pressure is created in the xylem, resulting in suction pulling the water upward just like you draw water upward when you suck on a straw.

An enzyme in a cell became dysfunctional because of an alteration. As a result, the DNA strands would not separate to begin the replication process. Which enzyme has been affected?
Answer:
C. Helicases
Explanation:
Helicases to be termed as enzymes that is blind and contains acid i.e. remodel nucleic or have protein i.e. nucleic acid. It is important as the time of DNA replication as it divided the DNA i.e. double stranded into one single standard that permits each and every strand for copied it
Also it cracks the bonds i.e. hydrogen that lies between the two strands this could create a replication fork.
Therefore in the given case, the helicases is affected
Answer:
helicases

What are some characteristics of the type of khoomii singing known as kargyraa?
Answer:
1. It produces a very deep sound.
2. It combines the vocal and vestibular folds at the same time.
3. It causes the vibration of the vestibular folds. A vibration cycle culminates at the second vibration.
4. There are basically two types, namely the Dag and Xovu styles.
5. It resembles a Tibetan Buddhist chant.
Explanation:
Khoomii, also known as Tuvan throat singing is a way of singing mostly characterized by the production of deep sounds and vibrations. A basic pitch which is supplemented by another pitch combine to produce the sound. It is sung by the locals in Siberia and Tuva.
Kargyraa is one of the four forms of this song and it typically involves the production of deep sounds and some vibrations of the vestibular folds at times. There are two basic types which are the Dag and Xovu. It also has a similarity to the chant produced by the Tibetan Buddhists.
