What would happen if a persons body temperature drop to low or got too high
summarize the events and forces that shaped human evolution
Answer:
Five different forces have influenced human evolution: natural selection, random genetic drift, mutation, population mating structure, and culture. All evolutionary biologists agree on the first three of these forces, although there have been disputes at times about the relative importance of each force.

Protrusion of the eyes is called exophthalmos. How is it related to thyroid dysfunction?
Elephants and rhinos tolerate the small birds that ride their backs and eat insects on their skin. The relationship between the elephants and the birds is called _____. coevolution mutualism commensalism parasitism
The relationship between the elephants and the birds is called commensalism.
Commensalism is a relationship between two organisms of different species in which one organism benefits from the other, and the other is neither harmed nor benefited. This type of relationship usually occur between a larger host, and a smaller commensal (the organism that benefits from the relationship). The commensal can benefit by obtaining nutrients, or shelter from the host organism, which is not affected. From the question given, the small birds obtain their food from the elephants, and the elephants do not benefit, and are not harmed in the relationship. This relationship is an example of commensalism.

What pathway provides the longest-lasting supply of ATP?
Answer:
Aerobic Cellular Respiration
Explanation:
Aerobic cellular respiration is the stepwise breakdown of glucose into CO2 and H2O through glycolysis, Kreb's cycle and The released energy is stored in the form of NADH and FADH2. These reducing powers drive the process of oxidative phosphorylation to produce as many as 36-38 ATPs. Hence, aerobic cellular respiration gives a long lasting supply of ATPs.

wich statement is true?
A) most stars are main sequence
B) very few stars are main sequence stars
C) no stars have made it to the main sequence
D) all stars have made it to the main sequence
Most stars are main sequence stars as they spend about 90% of their lifetimes in this phase, which is confirmed by H-R diagram observations.
A is correct
Explanation:The correct statement regarding the main sequence stars is: A) most stars are main sequence stars. Astronomical data confirms that about 90% of the stars observed in the sky are on the main sequence of an H-R diagram, which makes sense considering that stars spend the majority of their life in this phase, undergoing hydrogen fusion.
This is evidenced by the fact that stars are found in various spectral types ranging from O (most massive and most luminous) to M or L (least massive and least luminous) all aligned along the main sequence, representing different stellar masses.
What season is in August
Former NFL punter Ray Guy holds the record for the longest hangtime on a punt. If the ball leaves with an upward velocity of 128 ft/s from an initial height of 4 feet, how long will the ball be in the air? Use the formula H= -16t(squared) +128t +4, where h is the height of the ball in feet and t is the time in seconds since it is kicked. Round your answer to the nearest tenth.
Please fill the answer:) The hot plates on an electric stove change ______ energy into ______ and a small amount of _____energy.
The hot plates on an electric stove change electrical energy into heat and a small amount of light energy.
Explanation:The hot plates on an electric stove change electrical energy into heat and a small amount of light energy.
An electric stove works by passing an electric current through a coil of wire in the heating element. This current produces heat due to resistance. The heat generated is then transferred to the pot and its contents, causing the food to cook.
What do equinoxes signify
Answer:
Equinoxes are important in marking for change in the season.
Explanation:
The equinox is a marking for change in the seasons. The moment is important because it is the time of year when the day and the night are of almost exactly the same length. It's the starting of autumn or spring, that marks the starting of that season. It takes place twice a year around September 23 and March 21.
Thus, Equinoxes are important in marking for change in the season.
Describe why newer technology may not make older technology obsolete....?
Old technology instruments last for a longer period of time where as a very few new technology base equipment's works well.
What is new technology in science?
Technology is otherwise a concept which deals with human and its surrounding by using knowledge, tools, crafts etc.
The evolutionary change in technology can act as a driving force of innovation, productivity, growth and development of world.
It is completely based on bot scientific and technical knowledge to resolve the problem and provide a solution for a question like use of internet, mobile, laptop etc.
The new technology can be up two types such as Sustaining technology
and Disruptive technology based on working methodology.
Sustaining technologies refers to old or preexisting technology which is used to maintain a rate of improvement, which ultimately gives customer a satisfactory value.
On the other hand disruptive technology is completely a new technology which displaces the existing technology, it also lacks the scope refinement and performance.
Old technology is trustworthy but new technology is not.

what do genetics call alleles that are both expressed in the phenotype when they are together
The correct answer is:
codominance
Explanation:
Codominance is a kind of dominance wherein the alleles of a gene set in a heterozygote are fully represented. This results in offspring with a phenotype that is not dominant nor recessive. A typical example telling codominance is the ABO blood group system.
Which evidence supports the endosymbiotic theory? Select all that apply. Mitochondria and chloroplasts have a separate, simpler DNA from the nucleus DNA of a eukaryotic cell. These organelles' DNA resembles the DNA of prokaryotic cells. Mitochondria and chloroplasts self-replicate by a cell division process similar to binary fission, which is the way prokaryotes divide. The way mitochondria and chloroplasts synthesize proteins within the eukaryote cell is more similar to prokaryotes than to eukaryotes. There are living examples of prokaryotes, like cyanobacteria, that share similar features with both mitochondria and chloroplasts of eukaryotic cells. Observations of prokaryotic cells engulfing other prokaryotic cells and the engulfed cells becoming the organelles have been recorded.

c

d

Science is best described as a set of facts. The correct option is d.
What is science?Science is the methodical, empirically-based pursuit and application of knowledge and understanding of the natural and social worlds.
In the best situations, it attains the higher degree of wisdom, which is philosophy's main goal.
Thought experiments are occasionally used in philosophy, but as they are conducted solely in the mind, they are not genuinely scientific.
An area of study that is not a science, particularly one that is not a natural science or a social science that is the subject of scientific investigation, is referred to as a "non-science." The best way to define science is as a body of facts.
Thus, the correct option is d.
