Answer:
The main reason that Wegener's hypothesis was not accepted was that he suggested no mechanism for moving the continents.
Explanation:
It wasn't until 1928 that a Scottish Geologist, Arthur Holmes, came up with an explanation for why continents move. He believed that heat traps in the Earth caused convection currents. There were areas where fluids trapped beneath Earth's crust heat up, rise, spread laterally, then cool and drop back down. This hypothesis didn't have a wide acceptance either but was revived in the 1940s and 1950s when scientists started to learn more about the seafloor and the magnetic properties of oceanic crust.

Describe how a carbon atom is released from a fossil fuel like coal and travels into the atmosphere as a gas. How does it then end up in living things like plants and animals? Explain how carbon ends up back in the ground. Use the following terms in your typed response: CO2, C6H12O6, atmosphere, lithosphere, hydrosphere, biosphere, carbon sink, carbon source.
Explanation:
Animals and plants need to get rid of carbon dioxide (c02), this process is called respiration. Respiration happens when the plant/animal breaths in air and releases it as carbon, carbon then moves from fossil fuels to the atmosphere where they are burned. When humans burn fossil fuels to power cities, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.

than those with less helpful traits. Explain how this is demonstrated in the moth information

Nitrogen-fixing bacteria making
nitrogen available for use by other
organisms to utilize is an example
of..
A. mutualism.
B. commensalism.
C. decomposition
The nitrogen fixation bacteria makes the nitrogen available for the plants directly into the soil. This is an example of mutualism, where both bacteria and organisms are benefited.
Most leguminous plants like peas, bans, and cloves have colonies of nitrogen fixation bacteria. These bacteria are found attached to the roots nodules and tend to fix the nitrogen. Through this, the bacteria gain sugar from the plant.Hence mutualism is the end product of the interaction. This option A is correct.

He continued to breed purple-flower producing pea plants together over six generations. The results of Ralph's artificial selection are shown above. What did artificial selection do to the population of pea plants? A. caused a new species of pea plant to form B. increased its genetic diversity C. decreased its genetic diversity D. caused a pea plant to exhibit a new characteristic
Answer:
C
Explanation:
The correct answer would be that artificial selection decreased the genetic diversity of the pea plant.
Genetic diversity is a measure of the number of traits or characters.
Initially, the breeding produced a considerable population of both white and purple flower offspring. But as time goes on, the population of purple flower offspring increased while that of the white flower decreased till it eventually reached zero.
Thus, artificial breeding reduced the number of traits in the population of the offspring from two to one - a case of reduction in genetic diversity.
The correct option is C.

Very large, massive stars burn their fuel much ___________ than smaller stars.
Answer:
Very large, massive stars burn their fuel much faster than smaller stars. Their main sequence may last only a few hundred thousand years. Smaller stars will live on for billions of years because they burn their fuel much more slowly. Eventually, the star's fuel will begin to run out.

What is the importance of the amniotic egg?
Answer:
The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. But thanks to the amniotic egg, reptiles can lay their eggs nearly anywhere on dry land.

Define resource partitioning and how does this work?
Answer:
Resource partitioning is the division of limited resources by species to help avoid competition in an ecological niche. In any environment, organisms compete for limited resources, so organisms and different species have to find ways to coexist with one another.

(d) State the importance of mitosis in the growth of a multicellular organism, such
as a
flowering plant or a mammal.
Explanation:
Like other multicellular organisms, plants grow through a combination of cell growth and cell division. Cell growth increases cell size, while cell division (mitosis) increases the number of cells. As plant cells grow, they also become specialized into different cell types through cellular differentiation.

I or III only
B.
I, II, or IV only
C.

D.

Answer:
C. I, II, III, or IV
Explanation:
I got it right on study island
Jennifer is trying to determine the blood type of her parents for biology class. She knows that her blood type is B. In such case her father may have blood type A,B, AB, and O. Thus, option C is correct.
What is blood group?The three alleles that are A, B, and O are mainly responsible for controlling the major blood groups such as A, B, and AB, respectively. Due to this fact that humans are considered as diploid, each genotype could only include the maximum of two of them. Just to put it another way, just only two of these alleles could coexist in the single cell of the human at given time.
IA, IB, and I are considered as the three distinct alleles that could determine the person's blood type. I has been considered as the most common. These three alleles could be referred to as the A (for IA), B (for IB), and O for the sake of simplicity (for i). Because we receive one blood type allele from our biological mother and one from our biological father, each of us has two ABO blood type alleles.
Therefore, option C is correct.

Explanation:
Aerobic Process: Oxygen, Carbon Dioxide by-product
Anaerobic Process: Carbon Dioxide, Fermentation
Both: Produces ATP, Takes place in cells
What is respiration ?Respiration is a metabolic process in which an organism's living cells use oxygen to obtain energy (in the form of ATP) and release carbon dioxide as a byproduct of the oxidation of complex organic substances.
Anaerobic respiration occurs when there is no oxygen present, whereas aerobic respiration occurs when there is oxygen. Alcohol is produced by anaerobic respiration, whereas carbon dioxide and water are the byproducts of aerobic respiration. Compared to anaerobic respiration, aerobic respiration produces more energy.
Thus, respiration is a vital process of the body.

Between a Black father bear (genotype BB) and a Brown mother bear (genotype bb), they had several baby bears.Black fur allele (B) is dominant overthe brown fur allele (b), what is the probabilityof their offspringhave blackfur?
Answer:
100% or 1
Explanation:
This question involves a gene coding for fur color in bears. According to the question, black fur allele (B) is dominant over the brown fur allele (b). This means that a bear heterozygous for fur color (Bb) will be phenotypically black.
In this question, a black father bear (genotype BB) and a brown mother bear (genotype bb) were crossed, the baby bears will all have a genotype Bb (see punnet square in the attached image). Since all the offsprings of this cross have genotype Bb, this means that 100% will have black fur.
