Just did it on usatestprep
According to the question, Fusion produces much more energy than fission. Fusion is the source of nucleosynthesis in stars.
Fusion is the process that supplies the energy we receive from the Sun.
What are the 2 processes that produce nuclear energy?There are two fundamental nuclear processes considered for energy production: fission and fusion.
Fission is the energetic splitting of large atoms such as Uranium or Plutonium into two smaller atoms, called fission products. To split an atom, you have to hit it with a neutron.
Thus, option "B" is correct.

What are sound waves
Answer:
Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. The motion of the particles is parallel (and anti-parallel) to the direction of the energy transport. This is what characterizes sound waves in air as longitudinal waves.
Answer:
Sounds waves are a type of energy that is manipulated by vibrant energy. Different variations of vibrant energy allows us to hear different sounds.

Or, if you're talking about the Decepticon Soundwave, he's awesome.

How do scientists explain the slow rotation of the sun with respect to the rest of the solar system?
Answer:
The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots. The Sun's rotation axis is tilted by about 7.25 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March.
Since the Sun is a ball of gas/plasma, it does not have to rotate rigidly like the solid planets and moons do. In fact, the Sun's equatorial regions rotate faster (taking only about 24 days) than the polar regions (which rotate once in more than 30 days). The source of this "differential rotation" is an area of current research in solar astronomy.

Thick Walled isodiametric dead cells
Answer:Sclerenchyma
Explanation:Sclerenchyma is thick walled dead lignified cells, they are hard and elastic. The sclerenchyma cells are divided into two groups namely fibers and sclereids. Sclerenchymatous fibers are branched/unbranched, long, hard, pointed cells with tapering ends, thick walls, and narrow lumen.
Answer:
Sclerenchyma is Greek word where "Sclero-" means hard and "enchyma" means infusion. This tissue consists of thick-walled, dead cells and protoplasm is negligible. These cells have hard and extremely thick secondary walls due to uniform distribution and high secretion of lignin and have a function of providing mechanical support

Which of the following groups of organisms uses sunlight to convert carbon dioxide and water into sugar and oxygen?
a. producers
b. decomposers
c. carnivores
d. herbivores
The group of organisms which uses sunlight to convert carbon dioxide and water into sugar and oxygen are producers. Thus, the correct option is A.
What are Producers in the ecosystem?Producers are any kind of green plants present in the ecosystem. Green plants make their own food by using the sunlight (solar energy) and carbon dioxide gas from the atmosphere with the energy to make sugar. The plant uses this sugar (carbohydrate), also called as glucose to make many different products, such as wood, leaves, roots, and bark.
This process through which plants produce their food is called photosynthesis. Photosynthesis occurs only in the plants which have chlorophyll pigment (chloroplast).
Therefore, the correct option is A.

Roads are onen bum through forests for industrial purposes or as land is developed for residential and commercial needs. How would road construction
through a forest most likely affect the ecosystem?
Non-native species would replace native species
The number of primary consumers would increase
The natural succession of vegetation would change
All producers would be eliminated from the community
Answer:
The natural succession of vegetation would change
Explanation:
Originally, a forest is an area rich in biodiversity of species. It consists of different populations, and communities. According to this question, if a road is built through a forest for industrial purposes, this will negatively affect the biodiversity of such forest.
One notable occurrence that would result from this is the CHANGE IN THE NATURAL SUCCESSION OF THE VEGETATION. This change is the destruction of the ecosystem that occurs due to industrialization (road construction).

Organ _____
are made of multiple organs that work
together to maintain homeostasis in an organism.
Answer:
systems
Explanation: Cells are organized into tissues, and tissues form organs. Organs are organized into organ systems such as the skeletal and muscular systems. All of the organ systems of the body work together to maintain homeostasis of the organism. If homeostasis fails, death or disease may result.
Organ systems are made up of multiple organs that work together to maintain homeostasis in an animal or multicellular animals. In animals, organ systems are seen, which coordinate to form an organism.
What is an organ system?Multicellular animals are made up of multiple cells, and these cells work together to make a tissue. All the cells in a tissue have a single function, such as epithelial tissue or nervous tissue; these tissues form the organs. An example is the stomach, which is made up of different types of tissue such as longitudinal smooth muscle, circular smooth muscle, etc.
These organs collaborate to form organ systems like the digestive system, which includes the stomach, small intestine, pancreas, liver. Organs such as the stomach digest food in the organ system, and the small intestine aids in the process by allowing it to absorb into the blood along with digestion. Organ systems are interdependent, such as the digestive system, which is dependent on the nervous system, the circulatory system, and so on.
hence Organ systems are made up of multiple organs that work together to maintain homeostasis.
