most cheetahs that are added to a zoo are from the same area
Following conclusions supports the findings:
a. All of the zoo cheetahs come from just a few common ancestors.
b. The number of individual cheetahs currently in Zoos must be very low.
c. The variety of traits found in wild cheetahs is very narrow, possibly due to only a few of the animals surviving some event or series of events in the past.
What are characteristics of cheetah?Cheetahs are large cats that are known for their speed and agility. They have a distinctive appearance, with a slender body, small head, and long legs. They have a yellow-tan coat with black spots, and a long, bushy tail. They have a high flexibility and a unique skeletal structure that allows them to run at high speeds of up to 75 mph.
They have a unique tear-strip pattern on the face which helps to protect the eyes from the sun and dust while running at high speeds. They are also known for their endurance, and are able to maintain high speeds for longer periods of time than other big cats. They are carnivorous animals and mainly hunt small mammals, birds, and reptiles. They are also solitary animals, only coming together during mating season.

Why does an action that requires quick movement use a reflex arc?
sitting in a chair getting hit with a reflex hammer in the knee
Answer:
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
It uses a reflex arc because a reflex controls the brain and makes you think quick to do a fast movement that is known as a reflex, a example is something falling and your instinct is to catch it.

What about these molecules requires them to have this tetrahedron shape?
Answer:
There are four atoms required for having tetrahedron shape.
Explanation:
Tetrahedron shape molecule is made up of four atoms. The structure of tetrahedron shape molecule is just like pyramid. One atom is present at the top while the remaining three atoms attached to it at the bottom with bond angles of about 109.5°. So the structure of molecules only be possible if the molecule is made up of at least four atoms and have four unpaired electrons. Examples of such molecules are methane, water and ammonia.
what bond makes water molecules unique
Answer:
Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of most living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H₂O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. Water is the name of the liquid state of H₂O at standard ambient temperature and pressure. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds are formed from suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water moves continually through the water cycle of evaporation, transpiration, condensation, precipitation, and runoff, usually reaching the sea.

A multi-stage experiment was conducted with two different species: a nonpathogenic strain of Buttiauxella agrestis (Ba) and a strain of Haemophilus influenzae (Hi) carrying a plasmid with a virulence gene (Hi/pVir). The cultures were treated as described for each stage (1-5, below), then inoculated into healthy mice. The mice were observed 24 hours later.
1. When Ba was inoculated ---> the mice lived
2. When Hi/pVir was inoculated ---> the mice died
3. When heat-killed Hi/pVir was inoculated ---> the mice lived
4. When Hi/pVir was mixed with Ba, the mixed cells were incubated for an hour, and then only the Ba cells were inoculated ---> the mice died
5. When Hi/pVir was first heat-killed before being mixed with live Ba, the mixed cells were incubated for an hour, and then only the Ba cells were inoculated → the mice lived
a) Which was the method of DNA transfer: transformation, transduction, or conjugation? Explain your answer, including discussion of which species was the recipient and donor.
Answer:
Transduction
Explanation:
Transduction can be explained or described as the process through which foreign DNA is introduced into a cell by a virus or viral vectors.
It should be understood that initial Ba cells were not pathogenic or virulent, but the Ba cells becomes virulent when the DNA of the Hi/pvir was introduced into them during the incubation period. This process is what is known as transduction.

Explanation:
Choose the true statements about amyloid fibrils. 3 options are correct.
1) Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease.
2) An amyloid fibril typically forms from aggregates of misfolded peptides resulting from frameshift mutations.
3) An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues.
4) Soluble proteins that misfold and form amyloid fibrils become insoluble.
5) Proteins that convert to an amyloid fibril structure tend to have low solubility in their native form.
Answer:
Options 1, 3 and 4.
Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease.
An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues.
4) Soluble proteins that misfold and form amyloid fibrils become insoluble.
Explanation:
Amloid fibrils are peptide or proteins that are formed during invivo or invitro conditions. They ate formed when soluble proteins combine together to for insoluble fibres that are resistant to degradation. They are found in extracellular tissues and posses pathological effect. They accumulate after nerve cells and causes several illness.
An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues.
4) Soluble proteins that misfold and form amyloid fibrils become insoluble.
An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues.
Soluble proteins that misfold and form amyloid fibrils become insoluble.
Answer:
The correct answers are options 1) "Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease". 3) "An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues", and 4) "Soluble proteins that misfold and form amyloid fibrils become insoluble".
Explanation:
Amyloid fibrils are protein aggregates that can cause pathological conditions, for instance, they are found in brain tissue in people with Alzheimer disease. This disease, and other relates diseases, have a slow onset because most newly synthesized proteins fold correctly and the protein aggregates are made up misfolded proteins. This newly synthesized proteins are soluble, but once the proteins are misfolded, they form amyloid fibrils that are insoluble. The amyloid fibrils are stabilized by hydrophobic interactions between aromatic residues, which are formed within the complex of insoluble misfolded proteins.
In a community, before biomass is widely used as an energy source, several experts, including an ecologist,are hired to provide specific information. The ecologist would most likely be asked about
Answer:
The ecologist provide information about the ecosystem.
Explanation:
The ecologist is a person who provide information about the relationship between organism and its environment. The ecologist tell the people about the benefits of plants that exist in our environment. Biomass is widely used as source of energy in a community which is gained from cutting of trees. The removal of trees causes damage to the whole ecosystem so the people of community used less biomass or other materials as a source of energy.

What anatomical features makes it possible for Homo erectus to be a biped runner. Pick only one feature discussed in this week's material that allowed Homo erectus to be a biped runner. How is your chosen feature different from Australopithecus aferensis equivalent feature? Briefly explain the difference. Lastly, I would like you to briefly explain in your own words how endurance running would enhance the fitness of the Homo genus.
Answer:
Explanation:
The early homo erectus had tendors, ligament and mass spring which enables them become adapted runner.
The mass spring is energetic contributing to high speed.
The mass spring is mechanism aids in the exchange of kinetic energy and potential energy in the presence of tendors and ligaments that stores up the energy this enables them to run.
Nocturnal ligament that is present in homo erectus the helps to keep the head in position is absent in Australopithecus. This ligament usually activated during running in erectus and makes running more convenient.
Endurance running helps the early homo's to survival as they often run to get preys and animals to feed on. Because they do not have all the tools needed to hunt, the need to move in close range to get the prey hunted.

why there are more fungi in a forest than in a field? What role do they play in an ecosystem?
Answer:
Explanation:
Fungi grows more in damp conditions. There is also more food availibility of food in the forest for fungi. There is more dead matter in forests that fields.
Fungi and other decomposers feasst on dead matter and break them down. This increases soil fertility and allows more plants to grow.
Answer:
The role fungi plays is a decomposer.
Explanation:
Decomposers are plants that don't make their own food. They get their food from breaking down dead plants and animals. Usually you see fungi in forests because its more moist and has more greens. A field is an open space and has too much sunlight, not many animals die in a field as in a forest its more common.
