which statement best describes the water cycle:
a: a simple circular path that water takes around earth
b: a complex path that water repeats
c: a cycle if processes by which water circulates the earth's oceans , atmosphere , and land.
Answer:
C. A cycle of processes by which water circulates the earth's oceans, atmosphere, and land.
Explanation:
The term water cycle (also called the hydrologic cycle or the hydrological cycle) refers to the way water moves on, above, and below the surface of the Earth.
As the sun heats up the surface of our planet, water evaporates from it, rises up into the atmosphere, cools, and turns into rain or snow in clouds. Then, in this form, it falls on the surface again. This cycle constantly repeats itself, which means that water moves all the time.

Farmers have selected for increased oil content from corn. For a long time, the plants responded with steadily increasing oil content, but recently the response slowed and then stopped. When this line of corn is crossed to another line and the hybrids are selected, the oil content resumed its climb. What is a plausible reason for the lack of response?
A. The environmental conditions improved.
B. The genetic variation for the trait was exhausted.
C. There was too much genetic variation for the trait.
D. The environmental conditions deteriorated.
E. Artificial selection is different than natural selection.
Answer:
B. The genetic variation for the trait was exhausted.
Explanation:
Oil content is a quantitative trait, ie., a phenotypic feature that depends on the accumulative effects of many genes and the interaction of a genotype with its environment. During crop improvement, the plants (i.e., lines) containing desired alleles involved in the variation of this trait will be selected, thereby increasing oil content but simultaneously decreasing the genetic variation of the population. In consequence, after successive rounds of artificial selection, lines will not have sufficient genetic diversity to be again selected for this trait.

Compact bone contains cylinders of calcified bone called ______________________. These cylinders consist of 4 to 20 Compact bone contains cylinders of calcified bone called concentric rings of bone known as:___________________.
a. osteons, canaliculi
b. lamellae, canaliculi
c. osteons, lamellae
d. Haversian canals, lamellae
e. none of the above
Answer:
The correct answer is c. osteons, lamellae
Explanation:
An osteon is the basic functional unit of the cortical bone of a tubular bone. An osteon consists of a central canal that contains two vessels of Havers. Concentric bony laminae are arranged around this canal. These lamellae consist of bone cells and the surrounding base substance. Between the Havers canals there are Volkmann canals that connect the Havers canals. The construction of the cortical bone in these functional units has not yet been fully clarified. In general, it is assumed that these structures serve primarily to deliver tissue and signal transduction. This structure is also supposed to serve the stability and adaptability of the bone.
Explain why emerging efforts are focused on reducing health risks from exposure to chemicals rather than completely
eliminating those risks.
Answer:
Working with all chemicals carries some level of health risk, and modern society is dependent upon thousands of chemicals to maintain our standard of living. Therefore it is not reasonable to eliminate all chemical related health risks because that would require we stop using chemicals like cleaning supplies, gasoline, and fertilizers. The more practical approach is to minimize and manage the health risks associated with chemical exposure.

2. Think about an animal like a rhinoceros, a deer, or an antelope. What parts of their body other than their hair must be composed of quite similar material to your nails and hair
Answer:
horns and hooves
Explanation:
horns and hooves are made of kerotin, just like nails and hair.
Keratin is the protein that composes the external layers of the epidermis. It can be found in elements like feathers, nails, and hair. Other parts of the body that might be composed of keratin are horns and hooves.
-------------------------------------
Keratin is a fibrous protein that can be found in epithelial cells that cover internal and external surfaces.
Keratin is the main component of horns, hooves, feathers, hair, and nails.
Horns are hollow and pointed structures that emerge from the skull of the animal.
Animals get born hornless. As they grow they develop these structures. Most of them complete the development near the reproductive stage of the animal.
At sexual maturity age, competitive interaction increases, and animals use them to defend themselves and hurt the opponent. Males of some species also use them to attract females.
Hooves are very developed nails that cover the ugunaltes' fingers. These animals only use the extreme of the fingers to walk.
Like all nails, hooves grow continuously and wears out as the animal walks or runs.

If 100 grams of vinegar and 5 grams of baking soda are poured in a container, a small amount of gas will be produced. What will the final mass of the products be if the gas is trapped in the
container?
Answer: I think it is 105 grams
Explanation: Because classic chem and math states 100+5= 105
The final mass of the products if the gas is trapped in the container will be 105 g
From the law of conservation of matter, we understood that mass can neither be created nor destroyed during a chemical reaction but can be transferred from one form to the other.
This implies that the total mass of reactants must be equal to the total mass of products i.e
Total mass of reactants = Total mass of products
Considering the question given above, the following data were obtained:
Mass of vinegar = 100 g
Mass of baking soda = 5 g
Total mass of reactant = 100 + 5 = 105 g
From the question given above, we also discovered that the gas produced were trapped in the container.
This simply means that the total mass of reactants (i.e 105 g) will also be equal to the total mass of the products.
Thus, the total mass of the products is 105 g.

This fossil evidence suggests that
Answer:
millipedes were the first of these animal groups to evolve.
Explanation:
Fossils are structural remains of animals from the past. As these animals die, it takes years for the remains to be buried.
The millipedes are at the lower layer of the rock, next to insects, amphibians, and then rodents. This shows that millipedes existed and evolved before the rest of the found animal fossils.

8) Outline what you would need to know to answer the following question: of all the proteins that exist on earth at this time, what fraction of them have a known structure
Answer:
To solve this question, it is necessary to consider the number of protein structures that have been empirically verified and the number of Open reading frames predicted from sequencing data
Explanation:
The most common methodologies used to determine protein 3D structure are nuclear magnetic resonance (NMR) and X-ray crystallography. Although both methods are efficient, the determination of 3D protein structures in physiological conditions is a time and cost-consuming task. Moreover, due to recent advances in bioinformatics and sequencing methodologies, the amount of protein Open Reading Frames predicted from sequencing data (especially obtained from Next Sequencing Generation studies) is many times higher. Indeed, less than 5% of sequenced proteins have an empirically validated 3D structure.
