Answer:
precipitation and temperature
Explanation:
Temperature and water are considered major abiotic factors that affect species distribution in terrestrial ecosystems. The temperature can affect the distribution of terrestrial organisms due to many species maintain a constant internal temperature, while other species maintain a body temperature range that may be very different from the environmental temperature, and therefore they will not be able to carry out their metabolic functions. Hibernation is an adaptation that allows some terrestrial animals to escape temperature fluctuations. Moreover, water is another limiting factor for life, since water is critical for cellular processes. The waxy cuticle is an adaptation that allows terrestrial plants to avoid excessive water loss through transpiration.
Answer:
<u><em>definition;</em></u>
enzymes are protein that catalyze speed up the biochemical reactions and are not changed during the reaction . the molecules at which enzyme work are called <em>substrate </em> and enzymes convert them into different molecules called products.
<em><u>benefits of enzyme in digestion ;</u></em>
enzyme lower the activation energy in several ways. they may alter the shape of substrate and reduce the requirement of activation energy . enzyme may also lower activation energy by bringing substrate in correct orientation to react . enzyme break down <em>carbohydrates, lipids and proteins </em>which are component of human food .In digestion larger molecules are broken into smaller molecules like amino acids ,simple sugars ,fatty acid ,vitamins ,salts and water to provide to cells. these molecules are a part of larger molecules like protein ,polysaccharids and lipids . enzymes like amylaze, lypase ,salivary amylase, pepsin ; it is a very strong protein digesting enzyme it is released in its inactive form pepsinogen which is converted into pepsin with the help of H-C-L hydrochloric acid it takes part in digestion in stomach
Answer:
Quorum sensing is triggered to begin when<u> a sufficient number of bacteria are present .</u>
Explanation:
Quorum sensing -
Quorum sensing is the ability to detect and to respond to the cell population density by the process of gene regulation . Quorum sensing bacteria releases some chemical signal molecules called the autoinducers , that increases the concentration as the function of the cell density .
The detection of the minimum threshold concentration of an autoinducer leads to the alteration in the gene expression .
It can either be reflected or radiated back into space, it can get absorbed by the atmosphere, or it can reach the ground.
Good luck :)
I'm not very sure about this one but I think it's density
