Biology 1 Post Lab Questions: 1. Which method appear · which method appeared to have the most dramatic denaturing effect on egg albumin? Why do you think this method had a greater effect?
Hello. You have not introduced the methods used to denature the egg albumin. However, the most efficient protein denaturation method is the heating method.
The denaturation of a protein, such as albumin, occurs when an element causes the complete destruction of the protein's three-dimensional structure, in a completely irreversible way. The best way to do this is through heat. In this way, through a heating method, the heat breaks the hydrogen bonds that promote the structure of the protein, leaving it completely denatured.

In order to attract females, the male Bowerbird of Australia constructs elaborate structures called "bowers" on the forest floor. His bower is made from twigs, leaves, and moss, and is decorated with colorful ornaments such as feathers, pebbles, berries, and shells. If a female is sufficiently impressed with a bower, she will mate with the male who built it. This is an example of which of the five evolutionary forces
Answer:
non-random mating
Explanation:
The five different forces that influence species evolution are 1-non-random mating, 2-mutation, 3-gene flow, 4-genetic drift, and 5-natural selection. Non-random mating refers to phenotypic/behavioral differences that lead to preferential mating among individuals in a population (sexual selection). Mating behavior is a type of non-random mating pattern that includes mate choice (sexual selection) and increases reproductive fitness by increasing the chances of producing descendants (offspring).

name and describe the process occurring in the nucleus wich results in the formation of an mRNA molecule.
Answer:
The correct answer is - transcription.
Explanation:
Transcription is the process that takes place in the nucleus and the final result of the process is an mRNA molecule that encodes the information of a specific DNA sequence.
Transcription in prokaryotes is carried out in three stages.
Initiation: Here, RNA polymerase binds to the promoter region and transiently binds to the ‘initiation factor’ to initiate transcription.
Elongation: This is the step where the RNA strand starts getting longer. RNA polymerase “walks” along one strand of DNA. For every nucleotide recognized on the DNA template, it adds a complementary RNA nucleotide to the growing RNA transcript.
Termination: Transcription stops once the RNA polymerase reaches the terminator region. At this region, the RNA transcript and the RNA polymerase, both fall off. RNA polymerase transiently associates with the ‘termination factor’ to stop transcription.
Many scientists say that there is a good reason for gaps in the fossil record. Can you explain why some extinct animals and plants were never fossilized?
Answer:
For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the better the chance for it to be preserved.

In how many revolutions can a bicycle
wheel of diameter 4.9 m cover a dis-
tance of 46.2 km?
Answer: :Total distance to be travelled = 4.4 km
= 4400 m
Diameter of wheel = 70 cm = 0.7 m
Radius of wheel= 0.7 / 2 m
Circumference of wheel = 2 * pi *r
= 2* 22*0.7 / 7* 2
= 22*0.1
= 2.2 m
No. Of revolutions = Total distance / Circumference of wheel
= 4400 / 2.2
= 2000

Name two types of lateral pathways for the movement of sucrose from source cell into the sieve tube
Answer:
Diffusion and active transport.
Explanation:
Diffusion and active transport are the two types of lateral pathways that is responsible for the movement of sucrose from source cell into the sieve tube. Sugar molecules are moved into the sieve elements which are the phloem cells through active transport i.e. with the use of energy. The water produces turgor pressure in the sieve elements, which pushes the sugars and fluids down the phloem tubes toward the storage sites. it also moved through simple diffusion due to difference in concentration i.e. from higher to lower concentration region.

Differentiate between deforestation and desertification
Answer: deforestation = cutting down of trees in large scale due to which it causes soil erosion. desertification = a process by which fertile land become desert ,typically as a result for drought, deforestation etc. Deforestation is defined as the cutting down or clearing of trees from a wooded area. ... If trees are removed, the area can become much warmer and drier, which may result in desertification, which is a transformation of once fertile land into desert.

3. Most of the traits expressed in a person's phenotype are determined by Is
Most of the traits expressed in a person's phenotype are determined by is Phenotype.
What is Phenotype?Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.
An observable characteristic is simply referred to as a "phenotype." Pheno, which has the same root as the term "phenomenon," simply means "observe."
It can therefore refer to anything from a common attribute, like height or hair color, to the presence or absence of a disease. It is also an observable type of an organism.
Therefore, Most of the traits expressed in a person's phenotype are determined by is Phenotype.

which action is most likely to keep succession going and make an ecosystem more stable?
Answer:

Explanation:
What would have a greater detrimental effect: the moon stops rotating or the Earth
stops rotating? Defend your answer.
Explanation:
when the moon stops rotating around the earth
earth will be crush down because it is the pull of the moon gravit on the earth that hold our planet earth in the place.
A greater detrimental effect would have been caused if the moon stops rotating or the Earth stops rotating. This is because the rotating celestial bodies exert some kind of gravitational pressure in order to make them in the exact locations.
What happens when the earth stops rotating?If the earth stops rotating, this inhibition of motion suddenly causes the momentum that would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
If the moon stops rotating or the earth stops rotating then the other celestial body disrupts down. Due to this, the pull of the moon's gravity on the earth or the pull of the earth's gravity on the sun holds each other in their exact location.

Now assume that while studying the species, another researcher suggests that changes in land-use in the habitat of axis deer in Texas may be creating food shortages for the species and that the habitat is only capable of supporting approximately 2500 animals. Does this change your analysis of the situation
Answer:
Yes.
Explanation:
Yes, this change of conditions also change the analysis of the situation because the analysis is related to the environmental conditions. When the environmental condition for an organisms changed so it also change its presence in that environment. If there is plenty of resources such as water, food and space for living, the population of that organism will be higher in that region while on the other hand, if this organisms is moved to a place where the resources such as water, food and space is scarce then it will leads to decrease in population of that organisms so we can say that change in conditions also bring change in our analysis.

what is the process when an embryo embeds itself into the endometrium
Answer:
Implantation is a process in which a developing embryo, moving as a blastocyst through a uterus, makes contact with the uterine wall and remains attached to it until birth. The lining of the uterus (endometrium) prepares for the developing blastocyst to attach to it via many internal changes.
Explanation:

Human caused reductions of biodiversity, include pollution, invasive species, and overexploitation.
O True
O False
Answer:
True
Explanation:
Development, together with globalization, drove severe changes at a global level. The natural and original environments suffered from these effects and still are.
Human beings have constantly been altering the natural ecosystems and causing irreparable damages to nature. For many decades, development involved society and technology advance over new areas unpopulated by humans.
Some of the principal human activities responsible for biodiversity loss are
the uncontrolled use of unrenewable resources, overexploitation of renewable resources; land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures; the unplanned advance of cities, and opening of new roads to connect those cities.All of them involving
deforestation and fragmentation of natural landscapes; water, air, and soil pollution, species loss, and reduction of biodiversity.With globalization, transport around the world became normal. And when traveling around the world, new species are intentionally or unintentionally transported too. When these species, of animal or vegetable origin, get established in a new area, they overgrow to the point of turning invasive.
Invasive species are uncontrollable and cause severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.
But there are some background glitches in the system that are the principal responsible for all the mentioned activities. Some important aspects are lacking
The respect for nature, People´s education at different levels to care and protect wildlife, Interest in keeping ancestral knowledge, Planning and previous environmental impact studies, Policies to control human activities, Caring involved government.If, as a society, we lack these aspects, the possibilities of changing our impact on nature are far away.
