A primordial form of helium gas was found by the Endeavor space shuttle
Big Bang theory is a theory that endeavors to explain the origin of the universe. It stipulates that the universe exploded from a singularity and continues to expand today
Explanation:
Hope it helps:)
The statement 'the universe is continually heating up and gaining energy' is NOT true about the evidence to support the origin of our Universe.
The evidence states that the Universe is continually expanding, thereby celestial bodies are moving away from each other.In this regard, it has been proposed that a faster expansion rate might be due to an unknown force that is pulling galaxies apart.Moreover, it has also been suggested that as the Universe is expanding, its temperature slowly declines (i.e., the universe is becoming cooler) and loses energy.In consequence, the Big Bang Theory about the origin of the Universe states that it cools down as it expands.In conclusion, the statement 'the universe is continually heating up and gaining energy' is NOT true about the evidence to support the origin of our Universe.

Answer:
C. a distant luminous object travels rapidly away from an observer.
Explanation:
Option C is the correct answer.
Redshift is actually observed when a distant luminous object travels rapidly away from an observer.
In redshift, observers actually see an object that is travelling away from them and it has longer wavelength. The opposite is the blueshift where observers see a light traveling towards them and shifted to shorter wavelength.
In astronomy, redshift takes place when the object's visible light travels towards the red end of the spectrum.
A red shift is observed when a luminous object is moving rapidly away from the observer.
A red shift refers to a shift to a longer wavelength. It is observed when a luminous object is moving away from an observer. This is different from a blue shift where the luminous object is moving towards the observer.
Hence, in astronomy, a red shift is observed when a luminous object is moving rapidly away from the observer.

How did totalitarian regimes in the Soviet Union, Italy, Germany, and Japan come to
power after WW1?
I
Explanation:
A totalitarian ruler leads a government that maintains complete control over every
part of public and private life of the citizens in that country. The economic problems
that resulted from World War I and the Depression led people to question
whether democratic government could improve their lives. Totalitarian
governments appeared to provide a sense of security and offered a
strong direction for the future.
Both Communism and Fascism used aspects of totalitarianism
as part of their governments. In general, both used dictators, only
allowed one political party, and denied many individual rights.
Police terror was used for control and to get rid of any opposition.
Controlling media sources (newspapers, television, radio etc.)
with propaganda and limiting what was reported helped influence
what people thought. However, Fascism believed in an extreme form
of nationalism and pride in the country, while Communism focused on
the spread of their beliefs worldwide. Communism did not allow private
property and eliminated social classes. Fascism believed that each class
had a role to play in society and supported private property. During the 1920s
and 1930s, four major totalitarian governments developed – one was Communist,
The Soviet Union under Joseph Stalin
After Vladimir Lenin’s death, Joseph Stalin took power. He wanted to strengthen his power and the Communist state. He used
his secret police to stop any riots and arrest or kill anyone who spoke out against him. In 1933, he began the Great Purge to

eliminate his political rivals in the Communist Party and the government. He knew that in order to
compete with other modern countries, the U.S.S.R. (Soviet Union) needed to fix its economy. He
began a series of Five Year Plans to improve the Soviet Union’s industries. Production of steel,
coal, and oil increased dramatically, but Stalin set impossibly high production rates. Stalin took
control of all privately owned farms and began a program of collectivization. Hundreds of families
worked the collective farms to produce food for the country. Many landowners and peasants
resisted by destroying fields and killing their cattle and sheep. Millions died as a result of famine
from the damages and also attacks by the secret police to stop the rebellions. By the mid-1930s
Stalin changed the Soviet Union into a totalitarian state and made it into an industrial power.
Italy under Benito Mussolini
In the early 1920s, Italy was struggling economically and politically. Benito Mussolini’s Fascist
Party fought with the Communists for political power and won. Mussolini promised to restore the
power and glory of the Roman Empire. One way to do this was to expand Italy’s empire. In 1935, Mussolini invaded Ethiopia in
East Africa. Italy continued to expand by invading Albania in 1939. These invasions elevated Mussolini’s popularity and control.
Japan under Emperor Hirohito and Hideki Tojo
When the Great Depression hit Japan, many Japanese blamed the government for the economic problems. Military leaders
gained public support and won control of the government. Because the military kept Emperor Hirohito as the symbolic leader,

Riley lives near a polar zone, where it is cold. He visits his friend Thalia, who lives in a tropical zone, where it is warm all year. They live at similar elevations, and neither lives in a coastal area.
Answer:
The difference in the climate is because of the latitude.
Explanation:
The climate of a particular region differs from that of another region because of many reasons. One of the reasons is the difference in the latitude of the regions. The difference is in the amount of solar radiation received by the different regions. In the polar region, the temperature is low and it is cold there. While, in the tropical regions, the temperature is high and therefore it is warm in these regions.

the diagram illustrates the three stages of cellular respiration. In which stage is carbon dioxide released?
Answer:
Kreb's cycle
Explanation:
As depicted in the image of this question, aerobic cellular respiration is made up of three stages namely; glycolysis, Krebs cycle and electron transport chain (ETC). Glycolysis is the first to occur in the cytoplasm of the cell, after which it is followed by Krebs cycle, which uses the products of glycolysis as a starting material.
At the end of Krebs cycle, 2 molecules of carbon dioxide (CO2) are released as waste products. This release of CO2 occurs specifically at stage 3 and 4 of the citric acid cycle or Krebs cycle.
Answer:

Why do think predatory animals like owls are often threatened in habitats that have been exposed to those chemicals?
Answer:
At each higher level of consumption, the amount of toxin is magnified.
Explanation:
Those predators all eat smaller secondary consumers, and those secondary consumers eat the primary consumers, which a lot of the times are exposed to DDT. For example bugs are often the primary target for DDT, once those bugs are exposed to the DDT they carry it in/with them. When a fish eats the bug, that fish is now exposed to the DDT. When the fish is caught and eaten by an eagle that eagle and its young are now being exposed to DDT. The DDT might not effect the full grown eagle for its lifetime but it does effect its young.
Predatory animals like owls are often threatened in habitats that have a more complex chemical composition due to the biomagnification and bioaccumulation of toxic substances in their bodies.
What is biomagnification?There are producers, consumers ,and decomposers are present in the food chain. The food chain starts with the producers, such as terrestrial plants, phytoplankton, herbs, etc.
The producer makes the food by photosynthesis, and this food is taken by the consumer. From the primary consumer/ herbivore, the energy and nutrients pass to the secondary consumer, and then to the tertiary consumer. After the deaths of the producer and consumer, they are decomposed by the decomposer.
If in an ecosystem there are chemicals present, then the chemicals attach to the plants' leaves and are consumed by the herbivores. The carnivores feed on herbivores, and the toxic material present in the herbivores is passed down to the carnivores. As a result, the toxic chemicals in the carnivores accumulate over time. This is called biomagnification. The owl is a carnivore that feeds upon the insect, so the magnification is seen.
Hence, the owl is threatened due to biomagnification.

Which new animal adaptation may be favored if average
temperatures in a temperate forest decreases by 25
degrees C over 1500 years?
Answer:
If the average temperatures of temperate forests fell by about 25ºC during the period of 1500 years, the natural modification of the animals that would be favored would be that which allows an adaptation to the new climatic circumstances by the fauna of said forests, that is , to the notable drop in temperature. Thus, for example, animals would develop more voluminous furs, which would allow them to heat their bodies in a better way.
what is the timer for the increase in genetic variation that occurs when animals move into another population? Gene flow, sexual selection, natural selection, genetic disruption
Gene flow is the timer for the increase in genetic variation that occurs when animals move into another population.
What do you mean by gene flow?Gene flow is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies.
Gene flow is the movement of genes into or out of a population. Such movement may be due to migration of individual organisms that reproduce in their new populations, or to the movement of gametes (e.g., as a consequence of pollen transfer among plants).
Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.

Researchers Robert Briggs and Thomas King used ultraviolet radiation to destroy the nuclear DNA of frog eggs. Nuclei from adult skin cells and from tadpole-gut epithelial cells were cultured and then injected into eggs that had their nuclei destroyed. The results were tadpoles. Which conclusion is supported by the data from this investigation?
Answer:
Nuclei of gametes and somatic cells are similar to each other in its function.
Explanation:
The conclusion of the data is that the nuclei of gametes and somatic cells are similar to each other because both performs same function in the cell i.e. regulates activities of the cell. The nuclei of somatic or skin cells work efficiently in the egg cells due to similar composition and structure of nuclei that performs similar function in the cell so that's why injection of skin cell's nuclei into egg cells results the same i.e. formation of tadpoles.

Answer:
Biodiversity is defined as the variety of life forms existing on the planet and the number of species living within an area. The notion also covers the way diversity changes over time and moves from one location to another (“Facts on biodiversity,” n.d.). There is terrestrial and marine biodiversity that includes species living on Earth and in the sea. A number of species dwelling in a particular area helps to monitor the aspects of biodiversity. Maintaining biodiversity is important for people’s well-being since it plays a significant role in the contribution to human health and provision of raw materials. However, currently people often face the loss of biodiversity. Today this process is happening at a much faster pace than it did 50 years ago (“Facts on biodiversity,” n.d.). As a matter of fact, around 90 percent of all the fish on the planet was exploited within the last 50 years, a quarter of bird kinds were killed, and 70 percent of forests was destroyed. In addition, extinction threatens 18 percent of all mammals, 5 percent of the fish, and 8 percent of plants. Thus, it is possible to assume that the loss of biodiversity on Earth, which takes place nowadays, is directly linked to anthropological factors, including overhunting, overfishing, consumerism, and agricultural practices.
