Answer:
cells are different because they use the same set of genes differently. So even though each of our cells has the same 20,000 or so genes, each cell can select which ones it wants to “turn on” and which ones it wants to keep “turned off”.
In a typical conception, nuclear DNA from both parents is mixed into the fertilized egg. That DNA holds the majority of a person's genes, as well as all the genes responsible for a person's features.
What DNA differences observe in fertilized egg cell?The mother's mitochondrial DNA is exactly replicated in the egg. Every cell in the body is propelled by and assisted in dividing by this DNA.
Every cell has DNA in its nucleus, which serves as the blueprint for producing a wide variety of proteins within the cell.
Different signals can induce embryonic cells to choose particular DNA sequences, which can later be utilized to make proteins and create various cell types.
Therefore, it is possible for each cell to independently decide which genes to “turn on” and which to stay “shut off.”

what happens to species with higher resilience as compared to species with lower resilience?
Species with higher resilience have higher chances of survival as compared to species with lower resilience.
Resilience rate refers to the ability to rebuild following damage. When damaged, species with a higher degree of resilience quickly recover, increasing their chances of surviving. Any harm to a species caused by an internal element, such as sickness, or an external factor, such as food or climate change, can cause a species with a lower rate of resilience to collapse.
The capacity to respond effectively to adversity, trauma, tragedy, threats, or severe causes of stress is known as resilience. The idea of resilience has been used to describe a variety of systems, from cells to entire organisms.

in eukaryotes, where do transcription regulators bind? group of answer choices downstream of a gene. upstream or downstream of a gene. at the promoter region, near the tata box. upstream of a gene.
In eukaryotes, transcription regulators bind at the promoter region, near the TATA box.
In eukaryotes, the promoter region is present upstream near the TATA box. The promoter region is the site recognized by the RNA polymerase and where it binds so that transcription can occur.
The transcription factors also bind to the promoter region, so transcription initiation occurs. These transcription regulators are referred to as transcription factors. Transcription can be described as a process in which information from the DNA is coded into mRNA.
Mostly, the promoter sequence is placed near to the gene that is to be transcribed.

The tendons of the tibialis posterior, flexor digitorum longus, and flexor hallucis longus each pass around which bony landmark before reaching their respective insertions?.
The tendons of the tibialis posterior, flexor digitorum longus, and flexor hallucis longus each pass around which bony landmark before reaching their respective insertions called Medial malleolus.
The bony protrusion on the inside side of the ankle is called the medial malleolus. This is the tibia's distal end, which serves as support for the ankle joint's inner side. Additionally, the deltoid ligament, a significant ligament on the inside of the ankle, is attached to the medial malleolus.
Medial malleolus fractures are relatively rare. When they do occur, they typically take place as a part of a more complicated pattern of ankle fractures, such as trimalleaolar fractures and bimalleolar fractures (involving the medial and lateral malleoli, or the outer and inner sides of the ankle, respectively) (involving these two parts along with the posterior malleolus, or back of the tibia).

What is temperature?
A physical measure that describes how hot a substance or radiation is is called temperature.
There are three different types of temperature scales: those, like the SI scale, that are defined in terms of the average translational kinetic energy per freely moving microscopic particle, like an atom, molecule, or electron, in a body; those that only rely on strictly macroscopic properties and thermodynamic principles, like Kelvin's original definition; and those that are defined by practical empirical properties of particulates rather than by theoretical principles. With a thermometer, temperature is measured. It is calibrated in a number of temperature scales that historically defined themselves using different reference points and thermometric substances.

How has the sun caused changes in global and hemispheric temperatures over the past millennium?.
Changing solar output is most likely responsible for relatively high Northern Hemisphere temperatures during 1000-1100 A.D. and relatively low Northern Hemisphere temperatures during 1600-1700 A.D.
Recreations of the most recent 1,000 years have been finished with a few distinct models. A portion of the subtleties are unique, they all show a few comparable patterns in Northern Hemisphere atmosphere; relative warmth before the fourteenth century followed by chilly periods between the fifteenth and mid nineteenth hundreds of years. The warming of the twentieth century is, given the viewpoint of the earlier thousand years, extraordinary.
These reenactments intently coordinate the paleoclimate record of temperature throughout the previous 1,000 years. Contrasts between the time arrangement are because of a few variables, remembering vulnerabilities for the driving time arrangement, for instance whether solid or frail sun oriented constraining is utilized, and the flightiness of certain collaborations between the air, sea, land surface, and ocean ice.

a new restriction endonuclease is isolated from a bacterium. this enzyme cuts dna into fragments that average 4,096 base pairs long. like many other known restriction enzymes, the new one recognizes a sequence in dna that has twofold rotational symmetry. from the information given, how many base pairs of dna constitute the recognition sequence for the new enzyme?
For the identification of cleavage or cutting capacity of the particular newly isolated restriction endonuclease enzyme, we can provide the entire known nucleotide sequence during restriction activity, after that we can do sequencing for the analysis of at which specific position DNA is cutting down by that particular restriction enzyme.
Sequencing is the method used to know the genomics size of long as well as short stretch of DNA results in a shorter time period. There are two types of sequencing, first is ancient sequencing techniques such as Sanger sequencing and second one is next generation sequencing. Nowadays the next generation sequencing method is widely used for sequencing. These next generation sequencing is totally based on computer based technique.

Pine trees that are too tall or too short do not do as well as pine trees that are average in height. How is this an example of stabilizing selection?
Stabilizing selection is a condition where extreme traits have a negative outcome in the indivuals of a population, therefore the average value of the trait has the advantage. In this example, pine trees that are in the extremes of height (either tall or short) might have physiological disadvantages. On the other hand, pine trees with average height might escape this issues. For example, tall trees might have troubles with water transport, while short trees might have troubles with getting enough sunlight exposure. Average pine trees would not have disadvantages in either of the physiological examples described. With time, this trees (average height) will dominate in the population structure, whereas the other type of trees while be diminished.
