Answer:
Inserting arginine places a positively charged amino acid in a portion that is non-polar, creating the possibility of a hydrogen bond in this area.
Explanation:
Inserting arginine places a positively charged amino acid in a portion that is non-polar, creating the possibility of a hydrogen bond in this area.
What are amino acids?The amino acids are the basic building blocks of the protein nutrient. They are made up of amino group (―NH2), an acidic carboxyl group (―COOH), and an organic R group.
An asymmetric center is the carbon atom that is bonded by four different molecules.Among all the amino acids, the ones that have more that one asymmetric center include the isoleucine and threonine.
Of all the types of amino acids listed above, isoleucine and threonine are the two amino acids that have more than one asymmetric center.The sequence to date is: leucine-methionine-tyrosine-alanine-glutamine-lysine-glutamate. You insert arginine between the leucine and methionine.
Therefore, Inserting arginine places a positively charged amino acid in a portion that is non-polar, creating the possibility of a hydrogen bond in this area.

You are building a birdhouse when you cut your finger. Predict which body systems would be immediately involved with your
reaction to the cut.
Answer:
A.
Explanation:
These systems will be involved!
Hope this helps, have a great day.
The nervous system, circulatory system, and integumentary system are body systems involved immediately when you cut a finger.
The integumentary system is the system that groups the natural covering of an organism, for example:
SkinBarkShellThe nervous system is in charge of electrical signals. These signals are those produced by the senses such as taste, smell, sight. Also, they are responsible for sending signals of pain, satisfaction, pleasure, and others to the brain.
The circulatory system is the system in which blood is transported throughout the body for oxygenating and energizing the entire body.
When someone cuts themselves they feel pain (nervous system), blood comes out (circulatory system) and their skin opens and some of its lower layers (integumentary system) can be seen. Therefore, the correct answer is A.

I need to write my hypothesis based on this question
Do plants need sunlight to grow
My independent variable is the amount of sunlight each plant gets
Dependant variable is the growth of the plant
Everything else are controlled same
Answer:
If a plant gets more sunlight, then it will grow more because sunlight is beneficial and necessary for plant growth.
Explanation:
*This is only one way to write the hypothesis if you believe something else will happen you should reword it. The hypothesis should be based on your own educated guess.
Hypotheses should be written in the if-then-because format. This means to begin your hypothesis with the word if and explain your independent variable. Next, use the word then and explain what you believe will happen. Finally, write because and explain why you believe this phenomenon will occur. Hypotheses do not need to be 100% correct; it is common for scientists to be incorrect before an experiment. Hypotheses are just guesses based on research. If you are incorrect at the end of an experiment, simply explain that and what actually happened in your conclusion.
About how many times thicker is a
cell wall compared to a cell
membrane?
A. about twice as thick
B. about five times as thick
C. about half as thick
D. up to 100 times thicker
Explanation:
I think it's up to 100 times
A barrier enclosing the cell, the cell wall is located outside the plasma membrane. The plasma membrane can be up to 100 times thinner than a cell wall, hence option D is correct.
What is a cell wall?Cellulose, a polysaccharide sugar that gives the cell wall strength, makes up the majority of its composition.
The leaf blades of L. perenne and T. repens and the stems of Z had the thinnest cell walls (0–9 m) and the thickest (2–0–3 m) among the cells classified as thick-walled.
Compared to gram-negative cells, gram-positive cells have substantially thicker cell walls. The typical thickness of the gram-positive cell wall is 20–80 nm, whereas the typical thickness of the gram-negative cell wall is 5–10 nm.
Therefore, the cell wall is up to 100 times thicker compared to a cell
membrane, hence option D is correct.

Pump jacks use upward force and pressure to slowly move oil up a drill shaft. Which statement best describes an environmental consequence of this process?
O Soil is removed by the force and pressure of the drilling process.
High salinity of wastewater reduces soil fertility and growth of vegetation.
Wastewater is contaminated with oil and becomes sludge in landfills.
O Heavy metals are released into surrounding soil, poisoning local vegetation.
The main consequence of this process is that the soil is removed by the force and pressure of the drilling.
For the extraction of oil from the land, the vegetation is removed that destroys the habitat of many organisms as well as the degradation of soil occurs due to the force and pressure of the drilling machines.
In water, the aquatic organisms including plants and animals are adversely affected due to this process of extraction so we can learn that there are many consequences of extracting oil from the soil to the surrounding environment..

What are reactants in a chemical reaction?(1 point)
substances that are formed by reactions
outputs
inputs
substances that speed up reactions
Answer
D
Explanation:
inputs are the substances put in to make a chemical reaction.
The reactants are the inputs that are combined to form a product. The correct option is C.
What is a chemical reaction?A chemical reaction is a process that converts one or more substances, known as reactants, to one or more different substances, known as products. Chemical elements or compounds are examples of substances.
The most important types of events in the universe are chemical reactions. Plants grow, produce fruit, and decompose to become compost for new plants through chemical reactions.
Humans (and all other animals) reproduce, digest, grow, heal, and think as a result of chemical reactions.
Nuclear reactions are processes that involve the atomic nucleus. Reactants are the input substances that take part in a chemical reaction.
Products are the substances that are formed. The properties of the products differ from those of the reactants.
Thus, the correct option is C.

Which step in cellular respiration produces the most ATP?(1 point)
Krebs cycle
glycolysis
electron transport chain
lactic acid fermentation
Answer:
it's Kerbs cycle which produces most ATP in cellular respiration
Answer:
The answer is electron transport chain
Explanation:
The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS) present in mitochondria.
The formation of ATP occurs by oxidative phosphorylation. Theoretically, 34 ATPs are produced in the ETS by the complete oxidation of a glucose molecule. Electrons are transferred from NADH or FADH2 to O2 by a series of carriers and are coupled to ATP synthase for the formation of ATP.
