How do mycorrhizal fungi benefit plants?
aev [14]
Mycorrhizal fungi benefit plants in increasing absorption <span>capabilities</span><span>. Mycelium has the higher absorptive capacity for water and mineral nutrients than plant because of the large surface area of fungal hyphae and because hyphae are longer than plant root hairs. Also, some fungi can mobilize soil minerals which are unavailable to the plants' roots.</span>

Imagine you are sitting in a very quiet room when suddenly behind you there’s a very loud bang, like a firecracker exploding.
lisov135 [29]

Answer:

A. I would be startled by the sudden noise and would probably take cover some wheres. B. My nerves in my ears would send a signal to my brain causing my twitching muscle fibers to react quickly and heart might stop for a moment.  C. The heart rate would increase the brain would be aware that there may be more sudden noises or events your adrenaline would be pumping and your quick twitch muscle fibers would probably be tense or contracted ready to make quick sudden movements if necessary and your hairs would stick up i guess as extra senses for if something would touch you.  

Explanation:

not to mention but by the time you are startled your senses would probably be heightened due to you being  aware of your surroundings such as you would be constantly looking around you would hear better and probably move quicker for a short period of time due to pumping adrenaline.

Why does a protein not function after it has been denatured?
ch4aika [34]

Answer:

d. The normal bonding between the R groups has been disturbed and the protein loses its normal shape.

Explanation:

Denaturation is the loss of function of a protein due to its altered three-dimensional structure. To function properly, proteins must be present in a properly folded form. The three-dimensional structure and protein folding are mediated by weak interactions such as hydrogen bonds, electrostatic interactions, etc. An abrupt increase in temperature, pH or presence of some organic solvents causes protein denaturation.

The organic solvents target the hydrophobic interactions between the R groups of amino acids that make the core of globular protein stable. Extreme levels of pH target the net charge on proteins and thereby results in electrostatic repulsion between closely placed amino acids. Extremes of pH also disrupt the hydrogen bonding between the R groups of the amino acids. The effect is the loss of the three-dimensional structure of proteins, their partial or complete unfolding and loss of function.
