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.

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.

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.
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.

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.

Blood type in humans is an example of trait that has multiple alleles. The alleles for type A blood and type B blood are codominant, and type O blood is recessive to both type A and type B. If a girl with type AB blood has a brother with type O blood and a sister with type B blood, which of the following genotypes could it be possible for their parents to have?
AO and BO
AB and OO
AB and BO
AO and AB
The possible genotype is AO and BO.
An organism's genetic makeup is called its genotype, and it reflects all the alleles, or kinds of the gene, which are carried through the organism. Consequently, a test move can help determine whether a dominant phenotype is homozygous or heterozygous for a specific allele.
What are the 4 main blood groups?A person's blood type depends on the genes he inherited from his parents. ABO is the most well-known system for grouping blood groups, although there are other methods. There are four main groups in the ABO group: A, B, O, and AB. There are eight other blood groups in these groups.
More than 179 people in India are known to have Bombay blood type. If the organ donor belongs to the Bombay blood group, the donor liver must be free of A, B, and H antigens. In theory, the Bombay blood group donor can donate a liver to any blood group (universal donor).

Two brothers inheriting different sets of alleles from their parents results in genetic variation, influencing different phenotypic traits. This variation can produce different genotypes and phenotypes in siblings, due to the segregation and possible recombination of alleles during gamete formation.
Explanation:When two brothers inherit different sets of alleles from their parents, it results in genetic variation between the siblings. This variation is fundamental to the diversity seen within a species. In terms of genetics and inheritance, if an individual with a cleft chin who is homozygous (BB) mates with an individual with a smooth chin, which is the recessive trait (bb), all their offspring will exhibit the dominant cleft chin phenotype. However, if the cleft-chinned individual is heterozygous (Bb), the offspring will have a 50% chance of a cleft chin and 50% chance of a smooth chin. This is because the phenomenon of alleles segregating during gamete formation—each parent contributing one allele to an offspring—can produce different genotypic combinations like BB, Bb, or bb, thereby influencing the offspring's phenotype.
In another example, two genes could either be linked, leading to parental types of gametes (AB or ab) or unlinked, giving rise to gametes like AB, Ab, aB, and ab in equal frequencies. When heterozygous individuals are crossed with homozygous recessive individuals, we can observe the occurrence of both parental and nonparental types, suggesting that while linkage is frequent, recombination also occurs. This illustrates how different allele combinations can produce varying genetic outcomes in siblings.

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.
