d
set of facts.
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.
two brothers inherit different sets of alleles from their parents. what effect will they have?
Two brothers who inherit different sets of alleles from their parents will likely have different Phenotypes.
What is a phenotype?The phenotype is described as the set of observable characteristics or traits of an organism.
The phenotype is the physical and/or physiological characteristics as a result of the two brothers who inherit different sets of alleles from their parents .
The specific effects will depend on the specific alleles they inherit and how they interact with each other. They might have different hair color, eye color, height, susceptibility to certain diseases, and so on.

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.
Which of the following usually occurs with a short circuit
ANswer choices are:
a. All parts of the circuit will begin to carry higher amounts of current than normal.
b. The material within a fuse may begin to melt when the current ceases to exist.
c. All parts of the circuit will begin to carry lower amounts of current than normal.
d. Most of the current will flow through one part of the circuit.
____________________________________________________________
The correct answer is
a. All parts of the circuit will begin to carry higher amounts of current than normal.
Explanation:
When two or more than two conductors of different phases touch each other in a power line, the part of the impedance is shunted out of the circuit due to which a large current flow in the un-faulted phases, such current is called the short circuit current. Short circuit current decreases the impedance in the circuit while the current in the circuit increases.
a. All parts of the circuit will begin to carry higher amounts of current than normal.

Within a flock of birds, some birds have long narrow beaks, and other birds have short wide beaks. Environmental changes happen that make it harder for birds that have short wide beaks to find food. After several generations, most of the flock has long, narrow beaks. Which statement best describes the trait of the type of beak that a bird in this flock has?
A)Having a long, narrow beak is an inherited trait that is genetically passed down.
B)Having a long, narrow beak is an acquired trait that is determined by the availability of food.
C)Having a short, wide beak is an acquired trait that is found in birds that have learned to adapt to the environmental changes.
D)Having a short, wide beak is an inherited trait that is chosen by the bird as a result of its experiences.
Answer:
The correct answer is option A.
Explanation:
According to the given question environmental changes made it difficult for the birds with short and wide beaks to find food due to which their gene pool disappeared after few generations.
Environmental changes favoured the birds with long and narrow beaks due to which this trait was passed on to their generations and after few generation-long and narrow beak birds will dominate the niche. This is an example of genetic drift where the population has shown the directional shift.
Thus, option A is the correct option.

Explanation:
A fungus on the roots of a plant helps the plant absorb nutrients it needs from the soil, while the fungus gets what it needs from the plant. What type of symbiotic relationship is this?
The answer to this statement is Mutualism.
A symbiotic relationship in which one organism is benefited by the other organism and the other organism does the same to the organisms on it is mutualism. This is beneficial for both the organisms. The fungus on the roots of the plant helps in absorption of nutrients from soil, while the fungus fulfill its nutritional need from the plants.
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.
Which of the following accurately describes the role of energy in cellular respiration?
energy is a reactant
energy is not a part of cellular respiration
energy is a product
none of the above
Answer:
The correct answer is option energy is a product.
Explanation:
Cellular respiration is a process in which oxidation of food or glucose takes place to produce energy. This process proceeds in four processes: glycolysis, oxidative carboxylation, Krebs cycle and electron transport chain.
All of this process produces energy in the form of ATP or energy equivalents like NADH and FADH₂.
1. Glycolysis produces- 2 ATP, 2 NADH,
2. Oxidative carboxylation produces- 2 NADH,
3. Krebs cycle produces- 2 ATP, 6 NADH AND 2 FADH₂ and
4. Electron transport chain produces at last- 24 ATP from these reducing equivalents.
Thus, option energy is a product is a correct option.

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.
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).
