Answer:
Explanation
The Axon or nerve fibre is a long, thin projection of the neuron or nerve cells that sends signals in the form of electrical impulses from the cell body (soma) to the synaptic terminals. The axons are of two types: myelinated and unmyelinated. The unmyelinated axons lack myelin sheaths which make the transmission of electrical impulses slower while the myelinated axons transmit electrical impulses faster.
Answer: The energy stored in food molecule (glucose) is released in he process of respiration.
Explanation: Respiration is a cellular process in which glucose molecule is broken down into carbon dioxide, water and ATP is produced as end product. Respiration consists of following main steps:
1. Glycolysis: It occurs in the cytoplasm of cell, and each glucose molecule is converted into two pyruvates with help of ATP.
2. Formation of Acetyl coenzyme A: It is a connecting link reaction between glycolysis and Kreb cycle. In this phase Each pyruvate react with Coenzyme A to become acetyl coenzyme A.
3. Kreb Cycle: It occurs inside mitochondria. In this cycle each acetyl coenzyme A with fixed with CO to produce citrate which undergo in a cyclic reaction to produce ATP and NADH. .
4. Electron transport chain: It is the last step of respiration which complete in mitochondrial membrane. In this phase most of the energy is produced along with H₂O as by product.
Answer:
A. When two tectonic plates start to push into each other they can rise up and build mountains, or sink under and create deep valleys.
Explanation:
It is true
<span>Cytokines are tiny protein hormones that normalize immune
responses and facilitate cell-to-cell communication. The disproportionately
high levels of cytokines released by T cells enter the bloodstream and increase
the number of symptoms, including fever, biliousness, vomiting, diarrhea, and
sometimes tremor. Superantigens which includes staphylococcal toxins that may
lead to food poisoning and toxic shock syndrome.</span>
