<span>What is the chemical reaction that occurs when hydrogen peroxide is broken down by the enzyme catalase</span>
Answer:A. club
Explanation:
Fungi are eukaryotic organisms .they are feed on dead, decaying matter because they lack chloroplast. Most fungi are parasitic or symbiotic.
Fungi lacks root, stem and leaves. They however posses threadlike filaments called hyphae, which forms a larger mass called mycellium. Fungi reproduce asexually by spores. The classification of fungi are;
#zygomycetes, also called conjugation fungi .eg bread mold
#ascomycetes, also called sac fungi eg baker's yeast
#deuteromycota, also called imperfect fungi eg penicillium
#basidiomycetes .they are the commonly known mushrooms. They grow on wood and trees. Most of their species are edible. They are also called club fungi
The Incubator made it possible to maintain a controlled environment for cell cultures because most modern incubators act as a petri dish but in a more controlled state.
Answer:
roots, shoots, fruit, wild celery, and tree bark and pulp
Explanation:
Answer: Positive feedback loop
Explanation:
Even before the food reaches the stomach (before ingesting it), the glands of the stomach mucosa begin to release its gastric secretion. The main characteristic of this secretion is acidity, as measured by pH (one of the physiological variables).
This acidity is a result of the presence of hydrochloric acid, which is part of the secretion composition. In addition to it, water, pepsinogen (which will give rise to the enzyme pepsin) and the intrinsic factor. The acid has a function of the protection of the entire system by eliminating microorganisms. It is also responsible for the activation of pepsin (which only occurs with acid pH), the enzyme that digests proteins containing the amino acids leucine or phenylalanine or tryptophan or tyrosine.
The concept of Positive feedback loop states that the body tries to increase the value of a variable (acidity, in the case of pepsinogen) when it is below its optimal value (called a point adjustment) and decreases this value when it is above optimal.
