Answer:
A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C
Explanation:
Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).
That automatically eliminates Option B.
I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.
Option D is wrong because it includes no temperatures above body temperature.
Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.
That leaves Option A as the best answer. It includes only one temperature above 40 °C.
Answer:
Molecules stop moving at freezing point. Helium has the lowest boiling point. The molecules move very quickly at boiling point.
Explanation:
Heating up- molecules move faster. Cooling down- molecules move slower
Is it just me or is there nothing there?
Answer:
Fungi is a unique living organism and it is not considered plant or animal and forms its own kingdom Fungus. On of the most unique features of a Fungi is that its body is composed of thread like structure called Hyphae and produce fruiting bodies, in which spores are formed are help the fungus in reproduction.
Coming towards the question that what is the unique feature of the structure of Hyphae and fruiting body that helps them in their function.
1: Hyphae:
Hyphae are composed of thread like structures called Hypha that are filamentous in nature. Due to its filamentous nature, it helps the fungi to better absorb nutrients from soil and anchor the fungus well in soil.
2: Fruiting body:
The fruiting body is main organ of fungi concerned with reproduction. It has rounded cap like structure in which spores are formed and are disseminated from one place to another and help fungi in reproduction.
Hope it helps!
Answer: Mouth.
Explanation:
The mouth is known to be performing both the tasks of chemical digestion and mechanical digestion.
The food is ingested through mouth and the teeth perform the process of mechanical digestion by breaking down the food particles into smaller particles.
Then the saliva gets mixed into the food and the enzymes(amylase) present in the saliva helps in the digestion of carbohydrates.
So, mouth is the organ that performs the process of both mechanical and chemical digestion.
