Answer:
that allele pairs separate during the formation of gametes. This means that traits are transmitted to offspring independently of one another.
Explanation:
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 population of Anolis lizards lives on the mainland. During a storm, three groups of Anolis migrate to three islands, one large, one medium sized and one small Approximately 200 lizards establish on the small island, 2000 on the medium-sized island, and 20,000 on the large island. You may assume that:_____.
a. the lizards that initially establish on each island are, at first, representative of the mainland population.
b. the islands support these population sizes over time (so 10 generations later there are still just 200 lizards on the small island).
c. Rates of mutation are negligible (i.e. no mutation).
mating is random, and the effective population size is the same as the total population size. I. In the next generation, on which island will genetic drift be strongest?
1. Small island,
2. medium island,
3. large island
Explain: ii. After 10 generations which island would you expect to have the highest heterozygosity?
1. Small island,
2. medium island,
3. large island
Explain: iii. Some Anolis lizards on these islands have a dominant allele L1 that confers an improved ability to leap over allele L2 at the same locus. This difference in leaping ability causes selection to favor the L1L2 or L1L1 genotypes over L2L2 by about s = 0.002. Given this information, and the information above:
1. On the big island, Natural selection will make it more likely that the L2 allele is lost
2. On the big island, Genetic drift will influence the frequency of the L2 allele
3. On the small island, Natural selection will make more likely that the L2 allele will be lost On the small island, Genetic drift will influence the frequency of the L2 allele on the small
Answer:
(i) Small island
(ii) Large island
(iii) Option-3
Explanation:
In the given question, the three population of the Anoles Lizards migrated to three islands of different size.
(i) Genetic drift is a random or by the chance process which changes the frequency of the alleles in the population. The change in the frequency of the allele can be easily observed in the small population therefore the small island with the smallest size of the population will have the strongest genetic drift.
(ii) Heterozygosity of alleles that is with a dominant and a recessive allele is the result of the exchange of alleles in the population. The size of the population is finite on the island therefore the heterozygosity is not introduced in the small population but in a large population, it can be introduced as the mating is random.
(iii) The genetic drift is strongest on the small island therefore L2 allele can be easily influenced by this effect. The selection coefficient is very small that is 0.002 therefore no mutation is occurring on the island.
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.

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.

If Ryan were to become less active, what would happen to the number of extra calories he could consume. Explain plz!!!
Answer: The food consumed by the person may contain extra calories more then what is actually required by the body for daily physical work.
Explanation:
The extra calories can become harmful for the person if the routine daily activity becomes slow and less frequent. The extra calories will become the source of deposition of fats in the body. As the calories will not be used or burned out thus may be responsible for development of cases of obesity or overweight. The person may experience problems like diabetes, hypertension, and heart stroke.
Ryan will become obese if consume extra calories and become less active.
Answer:
The food consumed by the person may contain extra calories more then what is actually required by the body for daily physical work
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.
What is a possible consequence of increased ocean temperatures due to global warming? Mark all that apply.
Coral reef bleaching
Increased rates of mercury poisoning
Increased storm activity
Sea levels rising along coast lines
Answer:
Coral reef bleaching
Explanation:
The correct answer would be coral bleaching.
Coral bleaching is generally define as the change in color that results from the expulsion of green symbiotic algae from the tissues of the coral.
The expulsion of symbiotic algae from the tissue of coral is usually caused by a change in stressor factors of ocean water such as light, temperature, nutrient.
When the temperature of ocean water increases as a result of global warming, the vibrant color of corals may be lost because the change in stress condition usually leads to the degradation of the algal pigments or outright expulsion of the symbiotic algae from the tissue of the corals. When this happens, it leaves the coral tissues completely white and they are said to have been bleached.

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.

Compare and contrast the numbers of bones and composition of infant skulls and adult skulls
Answer:
Explanation:
The skull is located in the head. The bone of the skull of a new born is not fused at birth this is to enable passage during birth from the female opening while the skull bone of an adult at joined or linked to the other by sutures, this allows for growth of the skull as the child develops.
At birth the bone is 44 and are separated by a structure called fontanels this indicates the softness of the head. This fontanels allows growth of the skull as the child's develops.
