"Can dogs identify colors?" is an example of a scientific question. "Are dogs better pets than cats?" is not. Use complete sentences to explain the difference between these questions and why only one is scientific.
Answer:
"Can dogs identify colors?" is scientific while "Are dogs better pets than cats?" is not.
Explanation:
"Can dogs identify colors?" is scientific because it is a hypothesis that can be tested, it avoids opinion, it is specific, and the experiments involved in proving it can be repeatable. These are all characteristics of a good scientific question. "Are dogs better pets than cats?" is not scientific because it is opinionated, and it does not involve any experiments that would fail or prove it.

What is Room temperature?
The typical temperature range in a home is widely agreed to be between 68 and 76 degrees Fahrenheit, specific variations and geographic variations aside.
The use of smart home appliances, such as a smart AC controller, automates the maintenance of these typical house temperatures at all times, however keeping the ideal room temperature is a challenge.
The location, season, type of house, and personal preferences are just a few of the many variables that can dramatically affect the appropriate room temperature. When determining appropriate room temperatures, home architecture is a crucial factor.
Therefore, Yes, because the warmer seeds sprouted sooner.

You have learned that heat moves from warm areas to cooler ones. In solids, heat is transferred by the physical touching of molecules. This type of heat transfer is called conduction. Some materials, like metal, conduct heat better than other materials. In fluids (liquids and gases), heat is transferred by convection currents caused by differences in density.
MATERIALS
hot water
cold water
metal fork
plastic fork
stick of cold butter
large glass
watch or clock with a second hand
yellow and blue food coloring
playing card
four empty, identical plastic bottles (sports drink bottles work well)
access to a sink

What happened when the warm water bottle was placed over the cold water bottle? Why?
What happened when the cold water bottle was placed over the warm water bottle? Why?
Pt. 1
In gases and liquids, heat is usually transferred by convection, in which the motion of the gas or liquid itself carries heat from one place to another. ... If you boil water in a kettle, the heat is transferred through convection from the fire to the pot.
Pt. 2
This motion of fluids is called convection. In the set of bottles where the hot water was above the cold water, the cold water was already on the bottom, so there was no convection.
Pt. 3
When the bottle was put into the cold water, the air in the bottle contracted, taking up a smaller space in the bottle. The sides of the bottle pushed in when the air inside controlled

Explanation:
Use a Punnett's squares to show a monohybrid cross between pure breeding parents of tall (T) and dwarf (t) pea plants.
The tall trait is dominant and thus is represented by the uppercase letter "T". The dwarf trait is recessive and is represented by
to lowercase letter "t".
Answer/Explanation:
True breeding means the parents have two copies of the same allele (two of the same letter)
That means the monohybrid cross is TT x tt
T T
t Tt Tt
t Tt Tt
All the offspring have one copy of each and are Tt. Tall is dominant to dwa rf. So all the offspring will be tall.

During the process of replication, a molecule of DNA unzips, forming two single strands what makes up each individual strand of DNA?
A( paired adenine and uracil bases
B( Paired thymine and guanine bases
C( sugar groups attached to individual amino acids
D( nitrogenous bases attached to a sugar- phosphate backbone
DNA is a nucleic acid that gets duplicated by replication. The single strand of DNA is made of nitrogenous bases attached to a sugar-phosphate backbone. Thus, option D is correct.
What is DNA?DNA is the abbreviated form of deoxyribose nucleic acid that is the major molecule involved in inheritance and genetics. DNA undergoes a replication process where the two daughter strands, semiconservative in nature are produced.
The DNA is a polymer composed of the sugar (deoxyribose) - phosphate backbone along with nitrogen bases that include adenine, thymine, cytosine, and guanine. The phosphodiester bond, hydrogen bond, and glycosidic bonds are involved in interlinking the structural framework.
Therefore, option D. the sugar-phosphate backbone linked to the nitrogenous bases makes the structure of DNA molecule.

if the values for both mass and volume double, the value of the density will be?
Answer:
Stays the same.
Explanation:
Density = mass/volume
So if :
M/V = D
And if we were to double mass(M) and volume (V)
2M/2V = D
It will stay the same because the 2 and 2 would cancel out and we'd get the same density as the original value.

Valid Expressions are; t = ∛(d²/va), a = d/t², a = √(vd/t³), v = at
while the Invalid expressions are; v = a/t and d = at
Explanation:
Given expressions
1) v = a/t
2) t = ∛(d²/va)
3) d = at
4) a = d/t²
5) a = √(vd/t³)
6) v = at
First we get our units of parameters
V = m/s, t = sec, d = m, a = m/s²
so
1)
v = a/t
we substitute in our units of parameters
v = m/s² / s = m/s² × 1/s = m/s³
v ≠ m/s³
therefore it is false
2)
t = ∛(d²/va)
we substitute
t = ∛(m² / m/s × m/s²)
t = ∛(m² / m²/s³)
t = ∛(s³)
t = s
correct, the expression is true
3)
d = at
we substitute
d = m/s² × s
d = m/s² × s/1 = ms/s² = m/s
d ≠ m/s (because d = m)
so expression is false
4)
a = d/t²
we substitute
a = m / s² = m/s²
correct
the expression is true
5)
a = √(vd/t³)
we substitute
a = √(m/s×m / s³) = √(m²/s / s³) = √(m²/s × 1/s³) = √(m²/s⁴) = m/s²
so a = m/s²
correct
the expression is true
6)
v = at
we substitute in the units
v = m/s² × s = m/s² ×s/1 = ms/s² = m/s
v = m/s
correct
the expression is correctValid Expressions are; t = ∛(d²/va), a = d/t², a = √(vd/t³), v = at

t = ∛(m² / m²/s³)
t = ∛(s³)
t = s
correct, the expression is true
3)
d = at
we substitute
d = m/s² × s
d = m/s² × s/1 = ms/s² = m/s
d ≠ m/s (because d = m)

g Identify the statements that accurately describe how hydrogen ion concentration relates to energy production in oxidative phosphorylation. Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space. The pH in the mitochondrial matrix is lower than the pH in the intermembrane space. Energy is generated as a result of the difference in hydrogen ion concentration between the intermembrane space and the cytoplasm. Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain. Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.
Answer:
- Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.
- Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
- Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.
Explanation:
Oxidative phosphorylation is a metabolic pathway by which Adenosine Triphosphate (ATP) molecules are produced through the transfer of electrons from NADH or FADH2 to molecular oxygen (O2). The hydrogen (H+) ions are pumped from the mitochondrial matrix to the intermembrane space, and this movement of protons generates an electrochemical gradient across the mitochondrial membrane which is used by the ATP synthase to produce ATP. This gradient is generated by the movement of electrons through a series of electron carriers (e.g., cytochrome c and ubiquinone) that are embedded in the inner mitochondrial membrane. The movement of these H+ ions across the semipermeable mitochondrial membrane moving down their electrochemical gradient is named chemiosmosis and is an example of facilitated diffusion.

Potatoes are native to Monuntainous areas of Bolivia and Peru in South America, but are now grown widely around the world. What kinds or environmental conditions do you think areas must have in common for a crop to be successful around the world?
Answer:
Potatoes grew in the mountainous regiosn of Bolivia and Peru because they prefers such climates. Climates that are on the cold side but not so cold that the ground would be frosty. A temperature of between 60° to 70°F is considered ideal and anything above 80° F is considered too warm for them even though they have been known to adapt.
The soil should be very mildly acidic with a pH of between 5.0 to 5.5. Potatoes prefer to be grown in the full presence of the sun in well drained soils that are not compact or constantly wet.
The Environmental conditions are therefore;
