Answer:
Diffusion
Explanation:
Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space.
Answer:
B. Catastrophism
Explanation:
Catastrophism is the theory that states that the Earth was mostly shaped by very sudden effects. These sudden and short-lived events would occur worldwide in scope and change the Earth rapidly. This is in contrast to uniformitarianism that states that slow incremental changes made the Earth like it is today. Changes like erosion.
Answer:
Cochlear duct.
Explanation:
The mammalian ear is divided into three parts- outer ear, middle ear and inner ear. Ear is an important organ of the body responsible for maintaining the body's equilibrium.
The cochlear duct is well known as scala media. The cochlear duct is present between the perilymphatic chambers. This duct is interconnected at tip of the cochlear spiral.
Thus, the answer is cochlear duct.
Answer:
Cysteine
Explanation:
<u>Determine the Amino acid that is primarily involved in Binding </u>
The Amino acid that is primarily involved in Binding is Cysteine. while the other Amino acid ( i.e. Histidine ) will be involved in Catalysis.
since the enzyme is functional at pH 6 to 8. and Cysteine has a pH of 5, it should be deprotonated and used primarily for Binding .
The scientists rely on the following cues to hypothesise and test for the presence of life on various extraterrestrial bodies:
1. Presence of water
2. Presence of hydrocarbons
3. Presence of carbon
4. Presence of salt pans
The presence of hydrocarbons may indicate that there's anaerobic life thriving beneath the surface of the meteorite. The presence of traces of carbon may indicate that there was life once thriving on its surface ( which however is not possible in case of a meteorite because of its size). The absence of any of the above listed items will indicate that the surface of the meteorite is devoid of any life.
