Answer:
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA. For example, the sequence ATCGTT might instruct for blue eyes, while ATCGCT might instruct for brown. The complete DNA instruction book, or genome, for a human contains about 3 billion bases and about 20,000 genes on 23 pairs of chromosomes.
I hope this works and I helped :3
Explanation:
Answer:
<h3> Somatic: </h3>
- Skeletal muscle activation
- Voluntary
- Principally involved with movement "of" the body.
<h3>Autonomic: </h3>
- Can be excitatory or inhibitory on the target organ.
- Principally involved with the movement of materials through the body.
- Intestinal smooth muscle activation.
- Sweat gland activation
- Lacrimal gland activation
- Piloerector muscle
- Involuntary activation.
Explanation:
We can divide the nervous system into the central nervous system, which consists of the brain and spinal cord, and the peripheral nervous system, which consists of all the nerves that are throughout the body carrying information from and to the central nervous system.
We divide the peripheral nervous system into the somatic nervous system and the autonomic nervous system.
The somatic nervous system is the conscious one, that is to say, that we know and control what it does. It is voluntary. It has motor and sensory neurons that carry information to and from the central nervous system. The somatic nervous system is the one that makes us move our muscles to do an action.
The autonomic nervous system is involuntary. In other words, we can not control it consciously. It is the one that controls glands, organs, and smooth muscle, like the one that surrounds the digestive tract to move the food. As we can not consciously control it, this system can work exiting or inhibiting an organ depending on the situation.
Answer:
While a light microscope uses light to illuminate specimens and glass lenses to magnify images, an electron microscope uses a beam of electrons to illuminate specimens and magnetic lenses to magnify images. The resolution (the level of image detailing) is the main difference between these two microscopes.
A compound light microscope is a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nose piece closer to the specimen.
<h2>Biotic and Abiotic Factors Controls Viral Activity in Sea </h2>
Firstly, biotic are living components and abiotic are non living. Abiotic are the temperatures of ore and other items that are non-living. In the stream, the biotic factor can be small toads, shrubs, fish anything existing in the sea. In the sea, the biotic factors are any great fish or sea beings existing in that region including the any tiny bodies. In this way, all factors and components control viral activity in the sea.
