Answer:
I guess the answer to the question is ecology.
Answer:
Soma or cell body
Explanation:
The cell body of a neuron is also called soma. Soma contains a nucleus surrounded by cytoplasm. Several cellular organelles such as lysosomes, mitochondria, and a Golgi complex are present in it. The presence of free and ER bound ribosomes allows cell bodies of neurons to form proteins for growth and regeneration of the damaged axons. Therefore, cell bodies serve as metabolic centers of neurons.
Dendrites of postsynaptic neurons obtain the nerve impulse from the axon of the presynaptic neurons and deliver it to the cell body. Axon of a neuron carries the nerve signals away from the cell body towards the dendrites or the cell bodies of the other neurons.
Answer:
True
Explanation:
Algae are autotrophs and do not depend on plants for food and energy. Mushrooms are fungi that can derive their nutrition from dead and decaying bodies of algae in absence of plants and animals. So, both algae and mushrooms can survive in absence of plants.
Fruits, vegetables and grains are obtained from plants. If there would not by any plants, these plant products would not be available. Animals are heterotrophs and depend directly or indirectly on plants for food and energy. So, animals cannot sustain life without plants.
Hence, given statement is true.
Answer: Proteins
Explanation:
Proteins are known to be the most antigenic. Antigenicity describes the ability of the foreign materials to bind or interact with B-cell receptors or T-cell receptors.
The T-cell receptor recognizes the linear amino acid chain or sequence which is known as epitope.
They are usually long chains or amino acids or proteins. Some times polysaccharides can also show antigenicity. But they have less antigenicity.
Answer:
Explanation:
If the DNA codons are altered in an organism, the genetic code will be inaccurate. This will result in genetic mutations and disorders, depending on how drastic the change was. The two types of mutations are point mutations, that just replace one nucleotide. There's also frame shift mutations, where the amount of codons are incorrect.
