Generator produces the electricity required to run the factory 
True because they don't actually create electricity. Instead, they convert mechanical or chemical energy into electrical energy. They do this by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit.

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".

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 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.

Eliminate one word from each list and explain why you were able to eliminate it.
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.
