Ras is a GTP-binding protein involved in cell proliferation (division). In its active form, with GTP bound, Ras activates cell s

ArbitrLikvidat [17]

Answer:

E. They decrease the rate at which Ras hydrolyzes GTP.

Explanation:

Activated Ras has GTP bound to it, this propagates an intracellular signal to the nucleus where cell proliferation is induced. Thereafter proliferation is switched off by the hydrolysis of the bound GTP to GDP.

Therefore decreasing the rate of GTP hydrolysis causes Ras to remain active, ultimately leading to uncontrollable proliferation characteristic of cancer.

How do opinions compare to observations?

kifflom [539]

An opinion is a view or judgement formed about something that doesn't have to be based on fact or knowledge. It is a completely subjective statement (based on or influenced by personal feelings, tastes, or opinions). It reflects the speaker's personal views and thoughts.

An observation is the process or action of observing something or someone carefull in order to gain information. It is generally an objective comment (not influenced by personal feelings or opinions in considering and representing facts); the person making it does not wish to express a personal opinion on the subject but merely makes an observation regarding it.

lesya692 [45]

Answer:

this is a TRUE statement.

Explanation:

Different microbes grow in a wide variety of environmental conditions; however, most have preferences for certain temperatures, pH, and atmospheric gases because although microbes are widespread in their occurrence,they are found almost everywhere,in the air,water,soil,food,decaying matter,oil deposits,in plants etc.

but their number and their types vary according to the locality and environmental conditions.

Although, some microbes are always present and contribute towards natural flora BUT besides this others are present in specific environments such as some in hot springs bearing very HIGH TEMPERATURE RANGES for example: Thermus aquaticus.

some of them inhabit the acidic or alkaline soil feeding on HUMUS.

Most of the microbes prefer ATMOSPHERIC GASES i.e some require oxygen for their survival .For example: Pseudomonas.

some don't require O2 for survival i.e Spirochete.

IN SHORT, most of the microbes have preferences for various environmental conditions.
