Answer:
A animal 2b has no cell wall
the hydrogen is partially positive and the oxygen is partially negative and when by another water molecule, the 2 unlike ends attract just like a magnet does.
The ocean has separate layers which are also known as the zones of the ocean.
<u>Explanation:</u>
The surface layer of the sea is known as the epipelagic zone and stretches out from the surface to 200 meters (656 feet). It is otherwise called the daylight zone since this is the place the greater part of the obvious light exists.
There are five zones or layers in the ocean which are the following : Epipelagic Zone (Sunlight Zone), Mesopelagic Zone (Twilight Zone), Bathypelagic Zone (Midnight Zone), Abyssopelagic Zone (Abyss), Hadalpelagic Zone (The Trenches) The Hadalpelagic zone is also called the Trenches and is found from the ocean basin and below
Answer: The double helix is required to unwind and separate before transcription to take place.
Explanation: To unwind, it’s the first step, then the helical is used to separate the DNA so that other enzymes can help with the transcription process.
Answer:
b. muscle fascicle
c. muscle fiber
d. myofibril and. sarcomere
Explanation:
When muscle contracts, the myosin and actin filaments slide antiparallel to one another hence shortening the distance between the adjacent Z-lines of a sarcomere (a functional unit of striated muscle). Technically, nonetheless, the filaments do not shorten. A chain of sarcomeres make up a myofibril. Myofibrils bound together in bundles around a sarcolemma make up a muscle fiber. Several muscle fibers bundled together in an endomysium make up a fascicle. Several fascicles bound together in a perimysium make up a muscle. A muscle has blood vessels and innervated nerves that serve the cells and are bound overall by an epimysium.
The blood vessels and nerves in the muscle do not contract.
