Which of the following was evidence cited by Alfred Wegener that the continents were once one large land mass he called Pangaea?
Similar fossils were found around the world
The ages, layers, and types of rocks on mountains in separated continents were the same
The shapes of the continents looked like they could fit together
All of the above
Answer:
D. All of the above.
Explanation:
Alfred Wegener was certain than continents were once gathered together in a gigantic landmass known as Pangaea.
To support this theory, he collected different pieces of evidence:
Fossil evidence: Wegener stated that various fossils from plants and animals that were found on separate continents were located there and nowhere else, which suggested that these continents were once joined. For instance, the fossils of a freshwater reptile known as Mesosaurus are found in both Southern Africa and Eastern Southern America. As it is unlikely for this animal to move between both continents, it is suggested that both continents were once joined.Ages, layers, and types of rocks: Wegener matched rocks from separated continents and realized that they matched like puzzle pieces. He stated that mountain ranges that are located on opposite sides of the Atlantic Ocean possess the same rock ages, types, and layers. The shapes of continents look like they fit together: Alfred Wegener also suggested that the shape of separated continents looked like they were once joined. In fact, in 1910, he wrote to his wife the following thought: "Doesn't the east coast of South America fit exactly against the west coast of Africa, as if they had once been joined?"There’s a lot .

A girl carried a box of books up two flights of stairs to her attic. Her father carried a box the same weight up a ladder directly to the attic. The girl says she did more work on the box than her father because she walked further up the stairs, is she correct?
Answer:
The girl is correct because her father only went the distance of the ladder, whereas she went to the extension of two flights of stairs.
Explanation:
The work done by the girl and her father is the same. The discrepancy arises from the difference in perceived effort, not actual work done. In physics, work done against gravity for the same weight over the same vertical distance is equal, regardless of the path taken.
Explanation:The question asked pertains to the concept of work in physics. According to the definition of work in physics, work is equal to the force applied to an object times the distance the object is moved in the direction of the force. The force in this scenario is the same, as the same weight box is being lifted. The distance is also the same (the vertical distance from the ground to the attic). Therefore, regardless of the path taken (flight of stairs or directly using a ladder), the work done is the same.
It might seem that more effort is required to carry the box up the stairs due to the longer path, however, this is likely due to the additional force required to fight against gravity while taking the longer route, but this doesn't constitute to additional work done in terms of physics. Work Done Against Gravity is the significant concept here. The energy changed from one form to another to overcome gravity remains the same in both cases

A scientist observes plant roots growing through the mountain side. This is evidence for which type of natural process?
Answer:The answer is erosion
Explanation:
A scientist observes plant roots growing through the mountain side. This is evidence of Weathering
Explanation:
Weathering is the breaking down of rocks, soil, minerals. Weathering happens in the same place silently not happening as a sudden slide caused by erosion. Weathering is the natural process that takes place in the mountains.
Roots of lichens are pushed between the rocks. These slowly let their roots grow through the rocks. Then they slowly produce crack in the rocks and splits it. This happens slowly and gradually that it causes withering of the rocks.

One function of the hematic system is to _____.
cause voluntary and involuntary motion
protect the body
transport substances in the body
distribute blood through the body
The hematic system, or circulatory system, is crucial in transporting substances and distributing blood to all parts of the body. It enables nutrient and oxygen delivery, waste removal, defense mechanism operation, and helps in maintaining the body temperature and acid-base balance. The system also influences both voluntary and involuntary motions.
The function of the hematic system, also known as the circulatory system, primarily involves transporting substances in the body and distributing blood throughout the body. It reaches almost every cell, tissue, organ, and system in the body. The circulatory system is responsible for the transportation of materials, such as nutrients and oxygen, to different parts of the body, allowing our cells to function properly. Furthermore, it plays a critical role in our body's defense mechanism, distributing white blood cells and immune system antibodies to maintain our health. It also contributes to controlling body temperature and maintaining the acid-base balance.
Moreover, the circulatory system works closely with other body systems. For instance, it moves in conjunction with our body muscles, enabling us to perform both voluntary and involuntary motions. It also provides the physical site for the exchange of gases, nutrients, and other substances with body cells, ensuring effective metabolism and cellular processes.

Which statements describe what will most likely occur when warm air cools and the temperature drops to the dew point? Check all that apply.
A) Clouds form.
B) Air becomes more humid.
C) Solid ice forms on leaves.
D) Cumulus clouds disappear.
E) Water droplets form on grass.
Answer:
The correct choices are A,C AND E.
Explanation:
The formation of clouds occurs when the warm air cools and the temperature drops to dew point. The dew point can be describes as the temperature which occurs when the air becomes saturated into water vapour. The air becomes cooler and when humidity of 100% is acquired, water droplets form which lead to the formation of clouds. The formation of clouds has always been known to occur when temperature drops to the dew point.
As the warm air cools, it also results in forming tiny water droplets on the grass especially in the morning times. This most likely happens when the day has been warm followed by a cold night. The water droplets formed on the grass are known as dew.
When air cools to the dew point, the moisture it holds condenses forming clouds and dew on grass surfaces. The air's humidity does not increase, rather, the relative humidity does. The process does not result in freezing nor make clouds disappear.
Explanation:When warm air cools and the temperature drops to the dew point, certain phenomena occurs. The dew point is the temperature at which the air cannot hold all the moisture in it and some of it condenses as water vapor, leading to the formation of small droplets. The statements A 'Clouds form' and E 'Water droplets form on grass' best describe what will most likely happen, since clouds are formed due to condensation of water vapor in the air, and dew forms on grass for the same reason. Statement B 'Air becomes more humid' could be misleading; while it's true that the relative humidity increases (since it is defined as the ratio of the actual amount of water vapor in the air to the maximum amount of water vapor the air could hold at that temperature), the actual amount of water vapor does not increase. Statements C 'Solid ice forms on leaves' and D 'Cumulus clouds disappear' are not accurate as cooling to the dew point results in condensation, not freezing, and this process tends to create, not dissipate clouds.

Which of the following is an example of mutualism?
Answer:
One example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra. Oxpeckers land on rhinos or zebras and eat ticks and other parasites that live on their skin. The oxpeckers get food and the beasts get pest control
The best example of mutualism among the given options is a. Lichens.
Mutualism is a symbiotic relationship in which both species involved benefit. A strong example of mutualism is found in lichens.
Lichens are not a single organism but rather a close association between a fungus (usually from the Ascomycota or Basidiomycota phyla) and a photosynthetic partner such as a eukaryotic alga or a prokaryotic cyanobacterium.
In this mutualistic relationship:
The fungus absorbs water and essential minerals from the surrounding environment (air, rock, or soil) and forms the structural body of the lichen called the thallus.The photosynthetic partner provides carbon and energy in the form of carbohydrates through photosynthesis, which is utilized by the fungus.Some cyanobacteria associated with lichens also fix atmospheric nitrogen, adding nitrogenous compounds to the relationship.This mutualistic partnership allows both organisms to thrive in environments where they might not survive individually. Therefore, among the given options, Lichens represent a clear example of mutualism.

LATINU
ISK OP UP
Answer:
A reaction that joins the nuclei of two atoms into one
Explanation:
Think of the words "nuclear fusion".
Nuclear = "relating to a nucleus"
Fusion = "joining"
So, nuclear fusion is the joining of two nuclei into one.
A and B are wrong, because chemical reactions involve electrons.
D is wrong, because the splitting of a nucleus is fission.
Final answer:
Nuclear fusion is the combination of light atomic nuclei to form a heavier nucleus, releasing energy, and it is the fundamental process that fuels stars.
Explanation:
Nuclear fusion is best described by option : a reaction that joins the nuclei of two atoms into one. This process involves two or more light atomic nuclei colliding at high speed and combining to form a heavier nucleus. Nuclear fusion releases energy when these light nuclei fuse to form medium-mass nuclei; this is the same process that powers stars like our Sun. The simplest example of this is the fusion of hydrogen isotopes to form helium in the proton-proton cycle, which happens at the extreme temperatures and pressures found in the core of stars.

a hypothetical cell has approximate shape of a shape of a sphere. rhw diameter of thw spherical cell os six units long. another cell is shpaed like a cylider which has the diameter of 6 units and a height or length of 400 units long. determine the volum of both.
Answer:
The sphere: volume is about 113.1
The cylinder: Volume is about 11309.73
Explanation:
This is done by using the formula for the volume of a sphere ( v=4/3 pi r^3) and the formula for the volume of a cylinder (v=pi r^2 h). You plug in things such as radius, height, and pi or 3.14 into a calculator.
The volume of the spherical cell is 36π cubic units, while the cylindrical cell's volume is 3600π cubic units. The volume of a cell has a significant impact on its function and efficiency.
Explanation:
The question is asking to determine the volume of two different cells: a spherical cell and a cylindrical cell, both have a diameter of 6 units, with the cylindrical cell having a height of 400 units.
In geometry, volume describes the amount of space an object occupies. The formula to calculate the volume of a sphere is V = 4/3πr³ and for a cylinder, it is V = πr²h. Here, r stands for radius and h stands for height.
In the case of the sphere, since the diameter is given as 6 units, the radius would be 3 units. So, the volume of sphere would be V = 4/3*π*3³ = 36π cubic units.
For the cylindrical cell, the diameter is also 6 units, making the radius 3 units. The height is given as 400 units. The volume of the cylinder would be V = π*3²*400 = 3600π cubic units.
These calculations can give you the volume of the cell shapes, and further helps you understand how size and shape can affect a cell's function and efficiency.

If a gene has only one allele, how many different traits can the allele produce?
Answer:
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
Explanation:
Final answer:
If a gene has only one allele, it can produce one specific trait in an individual organism. However, within a population, multiple alleles for the same gene can exist, allowing for a range of traits to be expressed among the individuals in that population. The ABO blood type system in humans is an example of multiple alleles influencing various traits.
Explanation:
If a gene has only one allele, it can typically produce only one trait in an individual organism. This is because an allele is a specific version of a gene, and without an alternative allele to combine with, there is no variation at that gene locus in the individual's genotype. However, at a population level, multiple alleles may exist for the same gene, giving rise to various combinations of two alleles and hence multiple traits within the population.
An example of this phenomenon is the ABO blood type system in humans, where there are three alleles (IA, IB, and i) that can combine in different ways. These combinations result in the A, B, AB, or O blood types, showcasing how multiple alleles contribute to genetic diversity.
Still, it's important to note that while an individual organism with a single allele for a gene can typically only express one trait, the presence of multiple alleles at the population level allows for the range of observable traits (phenotypes) to expand beyond that single manifestation.
Silver has two naturally occurring isotopes. Ag-107 has an abundance of 51.82% and a mass of 106.9 amu. Ag-109 has a relative abundance of 48.18% and a mass of 108.9 amu. Calculate the atomic mass of Silver.
Answer:
The atomic mass of silver is 107.86 amu
Explanation:
The atomic mass is calculated by formula
Atomic mass = (Mass of first isotope x Abundance of first isotope) + (Mass of Second isotope x Abundance of second isotope)
In case of silver, the formula will be as
Atomic mass = (Mass of Ag-107 x Abundance Ag-107) + (Mass of Ag-109 x Abundance Ag-109)
Mass of Ag- 107 = 106.9
Mass of Ag- 109 = 108.9
Abundance of Ag-107 = 51.82/100 = 0.5182
Abundance of Ag-109 = 48.18/100 = 0.4818
Putting these values in the formula
Atomic mass of silver = (106.9 x 0.5812) + (108.9 x 0.4818) = 107.86 amu
To calculate the average atomic mass of silver, the masses of its isotopes are multiplied by their relative abundances and summed up, resulting in an atomic mass of 107.841428 amu.
Explanation:The average atomic mass of an element can be calculated by taking the weighted average of the masses of its naturally occurring isotopes, based on their relative abundances. For silver, we have two isotopes: Ag-107 with a mass of 106.9 amu and an abundance of 51.82%, and Ag-109 with a mass of 108.9 amu and an abundance of 48.18%. To find the atomic mass of silver, we perform the following calculation:
Atomic mass = (Percentage abundance of Ag-107 × Mass of Ag-107) + (Percentage abundance of Ag-109 × Mass of Ag-109)
Atomic mass = (0.5182 × 106.9 amu) + (0.4818 × 108.9 amu)
Atomic mass = 55.359866 amu + 52.481562 amu
Atomic mass = 107.841428 amu
Therefore, the average atomic mass of silver is 107.841428 amu.
There are approximately 200 different types of cells in the human body although all cells are dependent on other cells to perform body functions. Explain how your model supports this statement
Answer:
Group of cells construct the organs of human body which helps our body to function properly.
Explanation:
All living things are made up of cells. Human body is constituted of approximately 200 cells. Not every cell functions equally. Different cells function differently. However, the cells which has the same work to do they combine to form tissues, and groups of cell constructs human organs like heart, lungs etc. which functions together to control the body.
So it can be said that though not directly but cells are indirectly dependent on each other to perform body function.
Answer:
The model shows that some cells make substances such as proteins for other cells to use and support their functions. So, the model shows that each particular type of cell relies on other cells to support all the functions in the human body.
