Answer:
It depends the substance
Explanation:
Physical properties of a substance like Color, odor, density, melting temperature, boiling temperature can determine the purity of a substance.
What are the properties of a pure substance ?The matter can be classified as pure substances and mixtures.
Pure substances are made up same kind of particle and have a constant structure.
Pure substances can be up two types elements and compounds.
An element which consists of only one type atom, so it can not be broken down by using physical or chemical method. Elements are metals, non-metals or metalloids.
Compounds are the pure substances if two or more same type of elements are combined chemically, but these can be broken down into separate elements by treating them with chemical methods.

Roses attract more pollinators than tulips
Answer:
Pollinators are such as bees, insects, moths etc. that help in pollination of flowers.
Explanation:
When we heard about the pollinator we always think that theses are bees. Bees are very important in pollination of the plant. Pollinators are the insects that take some pollen from one flower to another flower and the procedure takes place for further.
These flowers attracts bees, insects, butterflies, bats moth and small mammals. Rose color and its tempt with fragrance attracts insects and bees. There are variety of flowers that attracts pollen but rose attract more because of fragrance and its color.
If you have a vloume of 55l and a density of 2kg/l what is the mass
Answer:
110 kg
Explanation:
Density = Mass / Volume ===> Mass = Density x Volume
Now follow the given:
- Density = 2 kg/L or 2000 g/L
- Volume = 55 L
Apply the rule:
Mass = 55 L x 2 kg/L = 110 kg or 110000 g. ( Liters is cancelled by Liters).

On topographic maps, how do you represent a steep slope?
A. Contour lines that are closely spaced
B. Contour lines that are dashed or dotted
C. A lack of contour lines
D. Contour lines that are far apart
Answer:
Contour lines that are closely spaced(Apex Approve)
Explanation:
On a topographic map the amount of elevation change is related to the number of contour lines. Using the same contour interval, the more contour lines over the same distance indicates a steeper slope. As a result, areas of a map where the contour lines are close together indicate steeper slopes

Which amino acids have side chains that fit into the specificity pocket of chymotrypsin?
Answer:
The aromatic amino acids; Phenylalanine, Tryptophan, Tyrosine
Amino acids with bulky side chains; Leucine and Methionine
Explanation:
Chymotrypsin is a member of the serine proteases, which is family of enzymes that hydrolyze peptide bonds through the action of an active site serine.
Chymotrypsin cleaves peptide bonds on the C-terminal of aromatic amino acids or amino acids with bulky hydrophobic sides chains such as phenylalanine, tyrosine and tryptophan, leucine and methionine. This specificity for aromatic amino acids is due to its large hydrophobic pocket and due to the complementary nature of these amino acids when they bind to the pocket.
What phrase describes a good scientific question? has a wide focus addresses a gap in knowledge does not lead to a testable hypothesis has a simple yes or no answer
Answer:
The correct answer is : addresses a gap in knowledge
Explanation:
A scientific question is an inquiry or question that may prompt a hypothesis and help us in explaining or the answering the reason behind the question by observation. A hypothesis is a speculative, testable response to a scientific question.
A proper scientific question has certain qualities.
It should be answerable but not in ye or no,
It should lead to testable hypothesis
prompts a speculation that is falsifiable

Explanation:
Here's the equations for photosynthesis.
~Hope this helps Mate. If you need anything feel free to message me.
The eqation which reporesent Photosynthesis is 6CO2 + 6H2O ® C6H12O6 + 6O2
Photosynthesis is the process by which green plants manufacture their food(in form of sugar) using carbon dioxide and water in the presence of sunlight. This is possible because of the presence of chlorophyll which creates a medium to absorb the sun's energy. The Light energy formed then converts water and carbon dioxide into oxygen and sugars.
The chemical equation to represent the process is as follows
6CO2 + 6H2O ------> C6H12O6 + 6O2.
sunlight
Here, six molecules of carbon dioxide and six molecules of water reacts in the presence of light energy captured by chlorophyll from the sun to form sugar and six molecules of oxygen.

Answer:
I believe its RNA
Explanation:
RNA is the new copy of DNA
Nucleic Acids make up DNA. DNA, in turn, is used as a blueprint to make RNA.
What is DNA?Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid.
The DNA of an individual can be found in almost all of their cells. DNA contains the bases adenine (A), cytosine (C), guanine (G), and thymine (T) (T).
All biological cells contain ribonucleic acid (RNA), a crucial biological macromolecule.
It plays a major role in the production of proteins by acting as a messenger for DNA, which in turn carries the genetic instructions necessary for life's growth and maintenance.
The DNA blueprint is first transcribed into RNA, another large macromolecule, to generate proteins.
To create proteins, ribosomes receive the exported RNA from the cell nucleus. The RNA sequence is read by ribosomes, which then use it as a template to make new protein molecules.
Thus, RNA is the molecule made from the blueprint of DNA.

Anytime you speculate about a problem and think of an answer based on what you
see on TV or read on the Internet, you are forming a scientific theory.
a. True
b. False
Answer:
b. False
Explanation:
A scientific theory must have strong support from testable facts that are confirmed (or rejected) by observational and/or experimental procedures. The scientific method is a rigorous process that consists of arising a conjecture (hypothesis) which can be subsequently used to make predictions from its logical consequences, and finally to obtain information from empirical observations/experiments in order to obtain a conclusion about the veracity of the scientific claims (i.e., a hypothesis must be testable). In consequence, a scientific theory can not be based only on 'light' conjectures, but trustworthy observational data from the real world.

Convert the following measurements to scientific notation format:
4.2 milliliters= ______?_______ x 10? liters
Scientific notations are used to write the numerical values in easier formats. The unit conversion of the volume can be written as 4.2 milliliters = 4.2 × 10³ liters.
What is scientific notation?Scientific notation has been the way to write the smaller and larger numbers in the form of coefficients and a base raised by the exponential powers. It uses decimal and base 10 to write the numerical values.
It is generally used to write the converted units that are larger or smaller. The exponential power to the base in scientific notation is non-zero integers and can be either positive or negative.
The units of volume can be converted from mL to liter as:
1 mL = 1000 liters
Given,
Volume = 4.2 milliliters
Converting units as:
1 mL = 1000 liters
4.2 mL = 4200 liters
It can be written in scientific notation format as: 4.2 × 10³ liters.
Therefore, the scientific notation is written as, 4.2 × 10³ liters.

-Functionalism is the field concerned with how mental processes help organisms adapt to their environment.
-Wilhelm Wundt established structuralism; he broke down consciousness into its two basic elements- subjective feelings and objective sensations.
-William James established functionalism; James disagreed with the functionalists and believed that consciousness couldn't be broken down as structuralists believed because it was a continuous stream of consciousness.
-Similarities are that subjective feelings and objective sensations are included in a continuous stream of consciousness as well as many other things. Organisms can adapt to their environment by using their subjective feelings and objective sensations and thoughts in order to solve problems that occur in their environment.
