An image of a mountain with three circles going up the side of it. The lowest circle is filled with many, smaller circles. The middle circle has fewer circles that are farther apart. The highest circle has the fewest circles that are the farthest apart.
What do the molecules in the circles model regarding altitude?
A. Air pressure increases at higher altitudes.
B. Air density decreases at higher altitudes.
C. There is a greater gravitational pull on air molecules at higher altitudes.
D. Temperature has a decreasing effect on air molecules at higher altitudes.
Answers
Answer:
B. Air density decreases at higher altitudes
Explanation:
Since air is compressible, air from higher altitudes will compress air from lower altitudes. As a result, air density at lower altitudes will be greater than air density at higher altitudes. Air particles at the highest altitudes, not being acted upon by air above it, will be more spread out.
You are studying the genomes of deep sea organisms when you come across a brand new species of lantern fish. In the lab, you measure the percent of nucleotides in the nucleus that contain adenine as their base and that percent is 30%. 10. Calculate the percent of thymine nucleotides: _______________ 11. Calculate the percent of guanine nucleotides: _______________ 12. Calculate the percent of cytosine nucleotides: _______________
Answers
Answer:
Thymine = 30%
Guanine = 20%
Cytosine = 20%
Explanation:
DNA is a double-stranded molecule made up of long chains of nucleotides (A, T, G, C). Each chain is the strand. However, According to Chargaff, the amount of adenine in a DNA is equal to the amount of thymine while the amount of guanine equals the amount of cytosine. That is:
(A = T) + (G = C) = 100%
All together, they all make up 100%. According to this question, the percent of nucleotides in the nucleus was measured to contain adenine as their base which is 30%.
If Adenine is 30%,. Then Thymine is 30% as well.
A = T = 30+30 = 60%
Hence,
60% + G + C = 100%.
G + C = 100 - 60
G + C = 40%
Since, G = C, 40/2 = 20%. Hence, G = 20% while C = 20%
All together,
A = 30%
T = 30%
G = 20%
C = 20%

a. Make a list of as many traits as you can think of that could be used to classify a new species.
b. Which of the traits in the list above would be most useful for classification at high levels (e.g. classifying things into different kingdoms or phyla) , which would be more helpful at lower levels (e.g. family or genus)
Answers
Answer:
a. My list is the following:
1. presence of photosynthetic pigments
2. presence of cell wall
3. body symmetry pattern
4. presence of cell nucleus
5. presence of specialized organelles
6. presence of hair
7. presence of mammal glands
8. niche (e.g., terrestrial or marine habitats)
9. diet (food habits)
10. position of a particular muscle
Explanation:
b. In the list above, traits such as the presence of a cell nucleus or specialized organelles can be used to classify organisms at the kingdom level (since these phenotypic features are observed in eukaryotic organisms but not in prokaryotes). In a similar mode, animals may exhibit two different body symmetry patterns: radial (around the central axis) and bilateral (two sides: left and right), thereby symmetry body can be used to classify organisms within the animal kingdom. Other features used to classify species at high levels include the presence of photosynthetic pigments in green plants (chlorophyll) and bacteria (xanthophyll), presence of cell walls in plants (composed of cellulose,) and fungi (composed of chitin), presence of hair and mammal glands (mammals), etc. On the other hand, ecological differences (e.g., food habits, niche) and minor anatomical differences (e.g., the position of a particular muscle) are helpful to classify species at the family/genus level.

Within a plant, photosynthesis is critical. It provides cells with the glucose they need for
energy. Photosynthesis is important for another reason, too. It's part of the flow of carbon
through organisms and the environment. This cycle, known as the carbon cycle, is essential
for life on Earth. It includes several processes that are occurring all the time. When plants
photosynthesize, carbon is removed from the atmosphere as carbon dioxide. When animals
and plants use cellular respiration, carbon is released into the atmosphere as carbon
dioxide. Organisms that die and are buried for millions of years turn into fossil fuels, which
are made of carbon. When humans burn those fossil fuels, carbon is released into the
atmosphere as carbon dioxide. Without enough carbon dioxide in the atmosphere, the
planet would be too cold. But too much carbon dioxide contributes to the warming of the
planet that could make it too hot to survive.
Based on the passage, what is one reason that the carbon cycle important?
A It adds carbon into the atmosphere whenever the level begins to drop too low.
B
It helps maintain a level of carbon in the atmosphere that is neither too hot nor
too cold.
с
It removes carbon from the atmosphere whenever the level begins to become
too high.
D
It releases carbon into space, preventing it from building up in Earth's
atmosphere.

either legally or spiritually, the community's farm, with the growers and consumers providing mutual support and sharing the risks and benefits
of food production."
-sustainable operation
-farmers' market
-farmers' cooperative
-CSA
Answers
Answer:
The correct answer is CSA.
Explanation:
Community Supported Agriculture (CSA) is an alternative model for the distribution of agricultural products directly from the farmer to the consumer, it consists of a group of people who form a cooperative to grow and consume food. Through this socio-economic model, consumers lend their support to producers, in exchange for a direct and regular delivery of biological products, that is, producers and consumers support each other and share the benefits and risks of food production.
Grandma Hippity Hop is worried about the ice that will be forming on her sidewalk this winter. She doesn't have money to waste on sidewalk salt that is ineffective, so Brenda decides to do some testing for her.
Indepedent Variable - ______________________________________________________
Dependent Variable - _______________________________________________________
Controlled Variables: (There are at least 5. Please list 2) __________________________________________________________________________________
__________________________________________________________________________________
Answers
Answer:
Independent variable- SIDEWALK SALT
Dependent variable- ICE FORMATION
Controlled variables- same size of ice, same sidewalk
Explanation:
Based on the information given in this question, Brenda is helping Grandma Hippity Hop test the effect of sidewalk salt on the formation of ice on her sidewalk.
In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter. In this case, the SIDEWALK SALT is the independent variable because it is the one being changed i.e used or not used.
Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured or recorded in an experiment. In this case, the ICE is the dependent variable because its formation is dependent on the SALT (independent variable).
Controlled variable or constants are variables of an experiment that are kept unchanged throughout the experiment. In this case, the SAME SIDEWALK AND SIZE OF ICE are used, hence, they are the controlled variables.
with reference to evolution of long neck in giraffe explain how natural selection brings about adaptation of species to its environment
Answers
Answer:
Explanation:
In order to reach specific items of food that meet the dietary needs of the giraffe, they must reach for food up in the trees. Giraffes with longer necks are open to a wider array of food whereas the short necked giraffes are limited. The longer neck is seen to be more favorable. When a trait is more favorable, it has a higher likelihood of being passed on. The less favorable traits are eliminated or "weed" out and the taller giraffes mate with other tall giraffes, generating a greater population with this trait. Again, it is solely dependent on what is available around them and their surroundings.

Blood is a critical body fluid. What role does blood play in the body? How is it usually cleaned, and how is it cleaned during dialysis?
Answers
Answer: Dialysis cleans your blood by passing it through a filter. If you do peritoneal dialysis (PD), the filter is the lining of your abdomen (your peritoneum). If you do hemodialysis, the filter is made of plastic. Your blood is on one side of the filter.
Explanation:Hemodialysis uses a machine to pull blood out of the body, filter it, and pump the clean blood back into the body again. The actual filtering happens in a part of the machine called a dialyzer, or artificial kidney. The dialyzer has two parts. One part is for blood.

A group of lions is chasing a zebra. The lions are most likely responding to which kind of stimulus?
the external stimulus of fear
the internal stimulus of fear
the external stimulus of hunger
the internal stimulus of hunger
Answers
Answer:
internal stimulus of hunger
Explanation:
Lions do not fear externally or internally of the zebra because they eat the zebra once they kill it and they are chasing after it so no fear what so ever.
Lions are naturally lazy and hunger is normally why they would be hunting because they need food to survive, however this is not always the case.
there have been a pair of documented pair of male lions known as the Tsavo Man-Eaters, who hunted for sport. Their den contained animal and man bones.
they actually made a movie about it, If you want to watch the movie just look up Ghost in the Darkness. You can actually see the lions in the Field Museum of Natural History in Chicago, Illinois.
