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.
Many building blocks are joined together to make a large biological
macromolecule. This chain of sub-units is called a(n)...
A- Isomer
B- Monomer
C- Dimer
D- Polymer
The reason why bonds form between atoms or molecules is either because they transfer electrons from one atom to another atom or because the
atoms are sharing their electrons with another atom.
O True
O False
In a water molecule, shared electrons spend more time
around the oxygen atom than the hydrogen atoms. As a
result, the oxygen atom is
slightly negative.
• very negative.
slightly positive.
• very positive

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.

Develop an opinion on whether this process should continue, providing evidence to support your stance.
Answer:
Triclosan was popularly utilized as biocide generally in present modern items like oral, cosmetics, and dermal items this expanded utilization causes microbial resistance among intestinal, dermal, and ecological generally E.coli and Salmonella enterica.
This microbial resistance happens because of moving out of metabolites, target modification or alteration, development of Biofilm, and bypass of metabolic blockage in the bacterial cells additionally acquires opposition against triclosan.
This causes serious endless supply of the items and prompts utilization of these biocides and ineffective.This is expected to acquiring cross resistance or co-resistance from the antimicrobial.

Describe the basic structure and functions of proteins.
Answer:
Each protein is made up of a unique number and order of amino acids. The protein that is created has a specific job to do or a specific tissue such as muscle tissue to create. The structure of amino acids is fairly simple. Each amino acid has an amino group at its core with a carboxyl group and a side chain attached.

Do autotrophs need to carry out cellular respiration? Why or why not?
Answer:
Yes, autotrophs need to carry out cellular respiration.
Explanation:
Autotrophs make their own food. ... Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy.

Where does a zygote implant after fertilization?
Fallopian tube
Vagina
Uterus
Ovary
Answer:
Fallopian tube
Explanation:
Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the Fallopian tube and into the uterus. The zygote then burrows into the uterus lining. This is called implantation.
Answer:
The Uterus is the correct answer. C.

___are a major component of the membrane of
all cells.
Answer:
Proteins and lipids are the major components of the cell membrane.
Explanation:
Depending on the membrane’s location and role in the body, lipids can make up anywhere from 20 to 80 percent of the membrane, with the remainder being proteins. While lipids help to give membranes their flexibility, proteins monitor and maintain the cell's chemical climate and assist in the transfer of molecules across the membrane.

What is migration ?Migration can be defined as the movement of a large number of organisms from one place to another place, there are many reasons for migration.
The term migration is used to define regular and periodic movements of the population away from or back to their place of origin, it can be up different types.
Some migration can occur for an entire lifetime and it happens to be a single migration of an individual. This is in the case for the Pacific salmon. On another hand, an individual may migrate frequently, like many of the migratory birds and other mammals.

Ultraviolet (UV) radiation can damage DNA by breaking weak bonds. Which of the following best explains how this occurs?
A
UV radiation disrupts the double helix structure by breaking the covalent bonds between the nitrogenous base pairs,
B
UV radiation disrupts the double helix structure to breaking the hydrogen bonds between the nitrogenous base pairs.
С
UV radiation is able to break DNA strands in two by breaking covalent bonds between the sugar phosphate backbone molecules
D
UV radiation is able to break DNA strands in two by breaking hydrogen bonds between the sugar phosphate bachoone molecules
UV radiation disrupts the double helix structure to breaking the hydrogen bonds between the nitrogenous base pairs.
WHAT IS DNA?
DNA, known as deoxyribonucleic acid, is one of the two types of nucleic acids. It is a long double helical structure found in the nucleus of cells.STRUCTURE OF THE DNA:
The DNA is made up of nucleotides. Each nucleotide consists of three components namely: phosphate group, nitrogenous bases and a pentose sugar. In the DNA molecule, the four nitrogenous bases are Adenine, Cytosine, Guanine and Thymine. Adenine and Thymine bonds together while Cytosine and Guanine bonds together. Weak hydrogen bonds holds one nitrogenous base to its complementary base.Therefore, an ultraviolet radiation can damage the DNA structure by breaking the hydrogen bonds between the nitrogenous base pairs.

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.
