What was the discovery scientists made in the 1950's that led them to then accept Wegener's theory of Continental Drift?
Answer & explanation:
The theory of continental drift emerged a long time ago. When mapping some points on Earth, scholars suspected that the continents were united in the past.
Francis Bacon suggested in 1620 that the east coast of the South American continent and the west coast of Africa fit together perfectly, giving the impression that they had parted in the remote past. A similar observation to this had already been made by another scholar named Abraham Ortelius, around 1596.
A century later, hypotheses became a scientific theory with previously elaborated arguments. Then, the theory of Continental Drift was officially born, when the German Alfred Wegener formulated it in 1912, establishing that the Earth had been divided, in its slow fragmentation, into two great continents, Laurasia and Gondwana.

1. How do you get your zenith distance from the altitude of the Sun at solar noon?
2. How do you get your latitude from your zenith distance and the Sun's declination?
Answer: The zenith angle is the angle between the sun and the vertical. The zenith angle is similar to the elevation angle but it is measured from the vertical rather than from the horizontal, thus making the zenith angle = 90° - elevation.
Since it is South of the Zenith, we add the zenith distance to the declination to find our latitude: our latitude = the declination + the zenith distance = -17° + 39° = +22° (North latitude).

HELP ME RIGHT KNOW PLEASE! ASAP what are 2 simular or different experinments related to invasive seaweed
Answer:
hope it helps:)
Explanation:
Invasive carp are fast-growing, aggressive, and adaptable fish that are outcompeting native fish species for food and habitat in much of the mid-section of the United States. ...
Brown Marmorated Stink Bug. ...
Answer:
When it comes to finding protection and a safe feeding ground, fish rely on towering blades of seaweed, like kelp, to create a three-dimensional hiding space. Kelp forests have been shown to be one of the most productive systems in the ocean with high biodiversity and ecological function. However, in recent decades, many kelp habitats have been taken over and replaced by lower turf-dominated seaweed species.
Researchers at the University of New Hampshire have found that this change in the seascape may impact the behavior of fish and could be leaving them less options for refuge and more vulnerable to predators.
"In each case, the cunner preferred and sought out the kelp, or similar seaweed species, to hide in," said Jennifer Dijkstra, research assistant professor in the Center for Coastal and Ocean Mapping at UNH. "Over and over, they gravitated to the kelp that is taller and because of its blade-like structure, provides a canopy to hide under."
Three experiments were conducted as part of the research recently published in the Journal of Experimental Marine Biology and Ecology; in situ video observations, a refuge choice study, and a foraging efficiency study. The video of cunner, a residential mid-trophic level fish, in their habitat showed that the fish preferred the kelp almost three times as much. The refuge choice experiment, where different seaweed scenarios were created for them to hide, supported the video observations that in all cases, kelp was the refuge of choice. The foraging efficient study showed very little difference between seaweed habitats.
"Our results suggest that the refuge-seeking behavior of the cunner may be impacted by the ongoing shift we have seen in our earlier studies of the increased dominance of the Dasysiphonia japonica (invasive seaweed) in the southern Gulf of Maine," said Dijkstra. "By losing their preferred refuge, the tall canopy-forming kelps, cunner were left with little option but to use the lower invasive seaweed turfs, which could give them less protection."
Three species known to be predators of cunner -- striped bass, pollock, and harbor seals -- were seen on the video highlighting the real threat to cunner in the surveyed habitats. Researchers say while this study did not directly measure predation, they believe that cunner may become more vulnerable prey since they were easily seen by the researchers hiding in the lower, less dense seaweed. Researchers also note this could be even more detrimental to juvenile cunner who look for safe refuge more often. While further studies are needed, they caution that continued reduction in available kelp cover may signal the beginning of density-dependent mortality in cunner populations which may have cascading effects on other members of the Gulf of Maine ecosystem.
Dijkstra and her team previously published a study that looked at seaweed populations over the last 30 years in the Southwestern Gulf of Maine and found the once predominant and towering kelp seaweed beds are declining and more invasive shrub-like species have taken their place. The invasive fiber-like red seaweeds had covered up to 50 to 60 percent of some areas, altering the look of the ocean floor and the base of the marine food chain.

What is Fermentation ?
Answer:
Fermentation is an enzyme catalysed, metabolic process whereby organisms convert starch or sugar to alcohol or an acid anaerobically releasing energy. The science of fermentation is called “zymology”. Fermentation is an anaerobic biochemical process

The photosphere and chromosphere are typically described by their visible
colors, such as red or yellow.
Chromosphere and photosphere are both layers of the Sun. The
photosphere is the visible surface of the sun which is characterized by a
yellow color.
The chromosphere is regarded as the layer found above the visible layer of
the sun(photosphere). They are made up of hydrogen and helium nuclei
which when ionizes produces a red color especially during an eclipse.

The smallest audio file format is typically OGG. However, because of its incompatibility, people typically choose MP3 when looking for an audio format that can still deliver excellent music while maintaining file size compliance. Thus, option C is correct.
What store music and podcasts on digital devices?Sound is saved and processed as a stream of discrete integers in a digital recording system, with each number denoting the air pressure at a certain moment. A microphone is attached to a device known as an analog to digital converter, or ADC, which creates the numbers.
The most obvious solution is to keep your files on the solid-state or local hard drive of your computer (SSD). This is helpful since it ensures that you always have easy access to your data. Keeping your music on an external drive is an additional popular choice.

why is the circulatory system of insects not involved in the respiratory mechanism of insects?
Explanation:
Insects do not have lungs, nor do they transport oxygen through a circulatory system in the manner that humans do. Instead, the insect respiratory system relies on a simple gas exchange that bathes the insect's body in oxygen and expels the carbon dioxide waste.
Unlike the closed circulatory system found in vertebrates, insects have an open system lacking arteries and veins. The hemolymph thus flows freely throughout their bodies, lubricating tissues and transporting nutrients and wastes.

Which increases speciation?
O A. Geographic isolation
O B. Lack of mutations
C. Asexual reproduction
O D. No predators
Answer: A.
Explanation: Scientists think that geographic isolation is a common way for the process of speciation to begin: rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations.
Answer:
A
Explanation:
Geographic isolation is a crucial component in speciation. If gene flow is disrupted for an extended period of time due to the geographical obstacles, populations can develop separately and eventually form different species.
