A disadvantage of using nuclear power is D. Nuclear power produces radioactive waste.
What is nuclear power?Nuclear power is a controversial topic, with proponents arguing that it is a clean and efficient source of energy, while opponents point to the risks of accidents and the dangers of radioactive waste.
One of the main disadvantages of nuclear power is that it produces radioactive waste. Radioactive waste is a byproduct of the nuclear fission process, and it can remain radioactive for thousands of years. This makes it difficult to store and dispose of safely. Another disadvantage of nuclear power is that it is expensive to build and operate nuclear power plants.

B. a protein filament or fiber
C. the basic contractile unit of muscle contraction
D.an organelle
Answer:
C, basic contractile unit of muscle fiber.
Explanation:
If you read the definition of sarcomere, this is what it says: "A sarcomere (Greek σάρξ sarx "flesh", μέρος meros "part") is the complicated unit of striated muscle tissue. It is the repeating unit between two Z lines. Skeletal muscles are composed of tubular muscle cells (myocytes called muscle fibers or myofibers) which are formed in a process known as myogenesis."

Which behavior is both territorial and used for courtship?
1.) baring teeth as a sign of aggression 2.) sparring or wrestling using antlers or horns
3.) dance rituals with potential partners
4.)defending a nest from predators
Answer:
2.) sparring or wrestling using antlers or horns
Explanation:
Territorial behavior is defined as the animal behavior in which animals protect their territory from other species.
Courtship behavior is defined as the animal behavior that is involved in mating and eventual reproduction.
Sparring or wrestling using antlers or horns is both territorial and used for courtship. Many animals or males uses their antlers or horns for wrestling or to fight with other animals to protect their territory while some males are involved in ritualized mating behaviors that include antler wrestling (sparring). The loud vocalizations during antler wrestling show the dominance of males that females and leads to mating.
Hence, the correct answer is "2.) sparring or wrestling using antlers or horns".
Which of the following best explains why a cell's plasma membrane is composed of two layers of phospholipids rather than just a single layer?
Answer: The hydrophilic tails are directed inward and the hydrophobic heads are directed outwards.
Explanation:
A phospholipid is made up of two ends a hydrophilic or water-loving end that is phosphate head and a hydrophobic tail that is made up of fatty acid tail. The arrangement of phospholipid in a bilayer structure allows the entry of oxygen, carbon dioxide, and lipids to pass through them via concentration gradient via simple diffusion.
Lipids are amphipathic molecules that compose the membrane. Membrane lipidic bilayers allow only the hydrophilic heads to interact with water inside and outside the cell, while hydrophobic tails remain in the interlayer space, away from water.
----------------------------------------------
Two lipidic layers compose the cell membrane. There are also proteins and glucans incrusted in between.
Since lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails, they need to form two opposite layers.
Lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells in contact with water. Meanwhile, their hydrophobic tails are against each other, constituting the internal part of the membrane.
Membranes are fluid, meaning that lipids and proteins composing them can move laterally, transversally, or rotationally.

How do the molecular formulas for all the amino acids differ?
The molecular formulas for all the amino acids differ - the R group or side chain.
Each amino acid has the same molecular structure with a central carbon atom, the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.
Each amino acid is exactly the same except for the R group. little side chain represented by the will be different depending on the kind of amino acid.For example, glycine has a hydrogen atom as its R group, whereas alanine has a methyl group (CH3).Thus, the molecular formulas for all the amino acids differ - the R group or side chain.

1. dog, cat, whale, oyster, mushroom
2. prokaryotic, eukaryotic, nucleus
3. bacteria, archaea, eukarya
4. fungi, animalia, plantae
5. sunflower, oak tree, button mushroom
*I also report incomplete answers, so please answer completely*
Answer:
1. mushroom
2. nucleus
3. eukarya
4. animalia
5. button mushroom
Explanation:
1. Mushroom because everything else in the list is an animal, while a mushroom is a fungi.
2. Nucleus because eukaryotic and prokaryotic are types of formations of a cell, while a nucleus is part of a cell and not a cell formation.
3. Eukarya because the Eukarya include all animals, plants, fungi, and protists. These organisms are eukaryotes, meaning they have membrane-enclosed nuclei within their cells. The Bacteria and Archaea are both considered prokaryotes, because their cells lack true nuclei, meaning a membrane does not enclose their genetic material.
4. Animalia because fungi and plantae are stationary organisms, while animalia are mobile. (ex. fungi and plantae= roots and animalia= feet/ not attached to one place)
5. Button mushroom because sunflowers and oak trees are producers, while a button mushroom is a decomposer.

Answer:
The theory of Continental Drift suggest that hundreds of years ago all the continents were one big continent called Pangea. Soon these contintents split up created the places that we live today. This theory was introduced by Alfred Wegener. His colleges thought he was crazy, but later studies proved his impossible theory to be true. By the process of "sea floor spreading" the continents were then ripped apart and drifted to where they are today.
Alchemy is the process of trying to turn non-gold metals into gold. It was practiced hundreds of years ago by scientists who believed that with the right amounts of heat or chemical reactions, they could make gold. After years of experiments and observations, gold was never produced. Which best describes the practice of alchemy? Alchemy was scientific, because scientists practiced it. Alchemy was scientific, because it included observations and experiments. Alchemy was pseudoscientific, because beliefs came before any observations of success. Alchemy was pseudoscientific, because some successful experiments inspired others.
Answer:
Alchemy was scientific, because it included observations and experiments
Explanation:
Scientific research is one that is done through a series not steps or methods. Observation and experiments are part of the steps in a scientific research.
Scientific research is done through investigation of various theories of science as well as formulating hypothesis. Scientists do not just resort to picking random answers concerning the phenomenons around us. They carry out investigations, observations, and would also formulate potential explanations for what is on ground, carry out experiments and then analyze their results to know if they are right or wrong.
Since the question says observation and experiments were done it is scientific
