Minerals and mining museum is long and narrow in order to
The correct explanation to this is:
The minerals and mining museums is long and narrow in order to “take advantage of orientation and cross ventilation”.
When the museum is narrow, this makes the skin which is separate from the structural grid seems to be alive in its sensitivity to the context. Additionally, the rammed-earth walls fitted with wind traps keep the interior space about 10 degrees Celsius cooler than the air outside.

just a few hours after the birth of a baby, the mammary glands start producing milk. which hormone stimulates this event
Answer:
The correct answer is the prolactin hormone.
Explanation:
Prolactin (PRL) or luteotropic hormone is a hormone, known for its different roles in enabling mammals, especially females. It is secreted in response to nursing, ovulation or mating, from the pituitary gland. Prolactin is manufactured by the pituitary gland in the brain.
Prolactin is majorly used to help women producing milk after a few hours of childbirth. The stimulation of the nipples and mammary gland leads to the release of prolactin.
Thus, the correct answer is the prolactin hormone.

The sugar glider in australia and the flying squirrel in north america are both small mammals with large expanses of loose skin between their fore- and hind-limbs allowing them to glide from tree to tree within their respective forest habitats. these two species are distantly related but are very similar in their overall appearance. the evolutionary explanation for their similarity is that
A plant that is homozygous for red flowers is crossed with a plant that is homozygous for white flowers. in the case of incomplete dominance, the flowers of the offspring will be
Incomplete dominance is defined as the genetic condition, in which a reduced ratio of the dominant allele is expressed. The offspring produced by the purebred parents is an intermediate between the two genotypes.
Let the genotype for purebred red flowers be - RR
Let the genotype for purebred white flowers be - WW
The cross between the true-breeding parent will is RR x WW.
The cross between purebred red and purebred white flowers will result in 100% pink progeny due to incomplete dominance.
Incomplete dominance is the phenomenon in which the dominant allele is expressed in the reduced ratio, such that the dominant allele does not mask the recessive allele completely, resulting in an intermediate offspring.
Therefore, the incomplete dominance will result in all the pink flowers, an intermediate between red and white flowers.

Which example describes migration caused by overcrowding?
Migration caused by overcrowding is exemplified by 'B. Hordes of rats flee a city when their numbers exceed the carrying capacity', as it reflects the population density reaching a point where resources are insufficient, necessitating migration to find more suitable environments.
The example that describes migration caused by overcrowding is: B. Hordes of rats flee a city when their numbers exceed the carrying capacity. This represents a situation where the population density of the rats becomes too high, leading to insufficient resources to support them, prompting a migratory response to seek out new areas with more available resources.
Migration is a natural behavior seen in many species and can be driven by various factors, including the search for food, mating opportunities, and more suitable climatic conditions. Animals may exhibit different types of migration, such as obligate migration, where species always migrate, facultative migration, where they only migrate under certain circumstances, and incomplete migration, where only part of a population migrates while the rest remain.
A student is performing a gram stain of a mixed culture of both
e. coli and s. aureus and he forgets to decolorize with ethanol. what should his slide look like?
Both types of bacteria appear to be dark purple (stained with gentian violet), both will have a gram-positive appearance.
In the gram stain, two dyes are used: gentian violet and Fuschia pink, the two stains are separated by alcohol bleaching.
Alcohol bleaching (+ acetone) is the most important step in coloring. It must be fast in order to eliminate the rich lipid wall of the gram negative bacteria that has retained the staining, to then be colored by the pink Fuschia.
Beware, the abuse of alcohol will result in all Gram negative bacteria.

Describe the impact of a waterborne pollutant on an aquatic community. write a 100-word report on how that pollutant affected aquatic life, what the effect was, and whether the effect is linked to biomagnification.
Water pollution can have a significant impact on aquatic communities, affecting aquatic life and the overall ecosystem. Pollutants such as heavy metals can biomagnify in the food chain, leading to higher concentrations in predatory fish species. This can have harmful effects on the fish themselves, as well as on the organisms that consume them.
Explanation:Water pollution is the contamination of water by an excess amount of a substance that can cause harm to human beings and/or the ecosystem. Pollutants can enter water supplies from point sources, which are readily identifiable and relatively small locations, or nonpoint sources, which are large and more diffuse areas. Waterborne pollutants can have a significant impact on aquatic communities, affecting aquatic life and the overall ecosystem. For example, pollutants such as heavy metals like mercury and cadmium can biomagnify in the food chain, leading to higher concentrations of these toxins in predatory fish species. This can have harmful effects on not only the fish themselves, but also on the birds or humans that consume them. Biomagnification is a process where the concentration of a toxin increases as it moves up the food chain.
Using an example of your choice, explain why biotechnology can be both helpful and harmful to society and/or the environment.
What term refers to organisms magnified with a microscope

Blood type is an example of a trait that's inherited by
A. incomplete dominance.
B. gender-specific alleles.
C. polygenic inheritance.
D. codominance.
Blood type is an example of a trait that's inherited by co-dominance.
CO-DOMINANCE:
Co-dominance is a type of inheritance pattern in which the alleles of a gene are neither dominant nor recessive over one another, hence, are simultaneously expressed. Co-dominance goes against the mendelian pattern of inheritance, which states that the dominant allele is expressed over the recessive allele. In co-dominance, both alleles are physically expressed. An example is blood type inheritance where alleles A and B are both expressed in an individual with AB genotype.Learn more about blood type: https://brainly.com/question/17058567?referrer=searchResults
