Answers
Answer:
C. Charged, polar, or non-polar
Explanation:
Amino side chains, also called R groups, are classified into the categories of charged, polar, and non polar.
These classifications can be determined by the structure and elements within the R group/functional group.

Name two ways that atoms can combine to become more stable in compounds
Answers
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.

Answers
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 .

What must happen before a chemical reaction can begin
- the activation energy must be exceeded
- the activation energy must be reached
-the concentrations of products and reactants must be equal
- the concentration of reactant molecules must be reduced
Answers
Answer:
its B
Explanation:
The incident that happen before a chemical reaction can begin the activation energy must be reached. Thus, option B is correct.
What is activation energy?
The extra energy is the minimum amount of extra energy which required by reacting molecule to convert into the product.
Factor at which activation energy depends are as follows:-
1: Activation energy depends upon the nature of reactant if reactant is ionic then required activation energy is less and if reactant is covalent then required activation energy is high.
2: Nature of catalyst if catalyst is positive then required activation energy is less and if catalysts is negative then required energy is high.
3: Activation energy doesn't depend on pressure, temperature, volume etc.
Temperature is one the important factor at which any reaction is depend. In any reaction if temperature is increases the rate of reaction is increases and if temperature is decreases the rate of reaction is decreases.
Here, is the Arrhenius Equation which shows the temperature dependence of the rate of a chemical reaction.
k=Ae^−EaRT
Where,
k= rate constant of the reaction
A= Arrhenius Constant
Ea= Activation Energy for the reaction (in Joules mol^-1)
R= Universal Gas Constant
T= Temperature in absolute scale (in kelvins)
Therefore, The incident that happen before a chemical reaction can begin the activation energy must be reached. Thus, option B is correct.

The first (F) one the population of the predator increases hugely while the population of the prey was neutral. And so both population didn’t seem to have any connection. Same goes for H. Graph G doesn’t make sense at all the population of the prey didn’t exist throughout the time in the graph but only exist in one single point of time and then just vanish again so that shouldn’t be the answer either.
In graph J, you can see the correlation between the two populations as the predator goes up and so does the prey.
You can search up on google predator-prey relationship graph to get better understanding.

Do protists (amoeba, Euglena, Paramecium) use similar structures to move? Explain.
Answers
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.

Scientists have developed a new herbicide for dandelions that is specifically designed to prevent the conversion of stored energy. Which process does this herbicide affect?
Answers
Answer:
Ability to make ATP or the release of oxygen from chloroplasts.
Explanation:
Given that, ATP which is an acronym for Adenosine triphosphate, is where the energy is stored and produced in a plant and at the same time Herbicides affect plants in the area of photosynthesis specifically affecting the release of oxygen from chloroplasts, which in turn prevents the generation of energy required for plant growth.
Hence, in this case, the new herbicides affect the ability to make ATP in plants or the release of oxygen from chloroplasts.
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.

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.
