3. Lawrence, Kansas and Nashville, Tennessee occupy similar latitudes. Why is one found in a grassland and the other in a forest biome
Answer:
The distance between Lawrence, Kansas and Nashville, Tennessee is 501.74 miles. So they are really far apart.
The location of Lawrance, Kansas is:
Latitude: 38.9560 Longitude: -95.2520.
And for Nashville, Tennessee is:
Latitude: 36.174465, Longitude: -86.767960.
So while the Latitudes are similar, the longitudes are not, and this is why you can see that the geography of each place is different.

In C3 plants the conservation of water promotes _____. In C3 plants the conservation of water promotes _____. photorespiration a shift to C4 photosynthesis photosynthesis the opening of stomata the light reactions
Answer:
The correct answer is "photorespiration".
Explanation:
Photorespiration is a process in plants, where molecular oxygen is taken in a light-dependent manner. Photorespiration is often considered a wasteful pathway because it competes with the Calvin cycle, which is much more efficient. In C3 plants the conservation of water promotes photorespiration. This occurs when the C3 plants close its stomata because the environment its too hot, or the carbon dioxide concentration drops to about 50 ppm.
If you pumped contaminated water from an aquifer, cleaned the water and pumped it back in what would happen?
Question 2 options:
The water would be re-contaminated by rock and soil in the aquifer
The water would clean the aquifer
It’s impossible to know what would happen
The water would be clean and stay clean
Answer:
It’s impossible to know what would happen
Explanation:
If contaminated water is pumped form an aquifer, cleaned and pumped back, it would be impossible to know what would happen unless the source of the contaminant is known.
If the source of the contaminant is known and removed before the water is pumped back into the acquifer, the water would be clean and stay clean provided that all the water was initially pumped off. If the source of the contaminant is not known, it would be difficult to predict what would happen.
What is removed to form a peptide bond between two amino acids? A. a water molecule B. an H+ ion C. an OH- ion
Answer:
A. water molecule
Explanation:
Glucose molecules from food sources provide energy to the cells of the human body. After a person eats, the level of glucose in their blood increases. If a person's blood glucose level becomes too high, a hormone in the pancreas, known as insulin, is released. Insulin helps move glucose out of the bloodstream. This causes the blood glucose level to decrease and return to equilibrium. The production of insulin is a mechanism that regulates the human body's internal environment and aids in
Answer:
regulating blood sugar levels
Explanation:
The primary function of the insulin hormone is to convert the excess glucose in the blood after a meal and store it for later. Glucose gets converted to glycogen, which is a compact molecule ideal for storage. When the body is need of energy, this glycogen is broken down to make up for the lack of glucose present in the blood.

What is the endosymbiotic hypothesis?
Answer: What does the endosymbiont hypothesis propose? It proposes that early eukaryotic cells acquired the precursors of mitochondria and chloroplasts by engulfing certain types of bacteria. ... Mitochondria, chloroplasts, and centrioles in eukaryotic cells each contain their own minute and unique supply of DNA.
Explanation:
The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.
Which of the following characteristics describes water’s ability to act as nature’s solvent? The polar nature of water molecules allows other polar and ionic substances to dissolve easily in water. The polar nature of water molecules repels hydrophilic compounds, preventing dissolution. The nonpolar nature of water molecules allows polar substances to dissolve easily in water. The polar nature of water molecules attracts hydrophobic compounds, encouraging dissolution. Assessment question An important property of water molecules is their capability to resist separating from one another call
Answer:
Water dissolves many biomolecules, because they are polar and therefore ... that acts as a solvent and surrounds a solute species) with a water solvent; also ... a substance capable of dissolving other polar molecules and ionic compounds. ... are either polar or charged, water readily dissolves these hydrophilic compounds.
Explanation:
Allison and Heather are going to conduct an experiment to see whether salt affects the growth of plants. They gather five groups of identical plants and give the plants in each group water with a different salt concentration. What is the outcome variable (dependent variable) for their experiment?
Answer:
The dependant variable is the growth of the plants.
Explanation:
The independent variable is what changes the dependent variable.
for example, the type of salt concentration ( Independent variable ) is/ isn't going to change the growth ( dependant variable ) of the plant.
The dependant variable is the growth of the plants.This is the outcome of the experiment in which salt affects the growth of plants.
What are plants?Plants are the eukaryotes means they are multicellular organisms and they belong to the kingdom Plantae. So, the scientific name of plants are Plantae and its domain is Eukaryota.
The plants are of many types such as shrubs, herbs, mosses, ferns, trees and they grow on a particular place by absorbing inorganic substances and water from the soil through the roots.
Plant are also known as autotrophs as they prepares there own food in the presence of sunlight. Due to chlorophyll present in them the plants shows green colour.
Plants are also known as producers because they produce food to feed others.
Therefore, the dependant variable is the growth of the plants.This is the outcome of the experiment in which salt affects the growth of plants.

ASAP What are considered characteristics of science? Select all that apply. - Scientific experiments are not falsifiable. - Scientific experiments are peer-reviewed. - Scientific conclusions are based on anecdotal evidence. - Scientific phenomena are observable. - Scientific hypotheses are testable.
Answer:
- Scientific experiments are not falsifiable.
- Scientific experiments are peer-reviewed.
- Scientific hypotheses are testable
Explanation:
The scientific method refers to the process of examination of scientific hypotheses. This method is rigorous and requires 1-to raise questions about an observed phenomenon, 2-to produce an experiment and 3-to confirm this hypothesis by analyzing the results. The last step of scientific research is the peer review process, where independent researchers (usually 2-3 researchers) review the observed evidence in order to confirm or reject the results obtained from the experimentation. This hypothesis must also be testable, ie, it is imperative that it can be confirmed in further experiments.
