This period of time is considered lost to history, no important record about the era has survived, The cause of the dark ages was the collapse of the Roman Empire and the invasions and raiding that characterized it.</span><span />
Not sure if this is the format you want it in but
F1:
Genotype: RWHh, RWHh, RWHh, RWHh
Phenotype: basically all of them would have the roan coat and they would be hornless
F2:
Genotype: WWHH, RWHh, RRHh, RWhh
Phenotype: one will have a white coat and hornless, roan coat and hornless, red coat and hornless, roan coat and horned
Hope this somewhat helped
Answer:
A. The RNA polymerase subunits of the P.syringae strain probably have extra flexibility so that they can move more freely in colder temperatures.
Explanation:
Because there is no difference in the amount of the RNA polymerases but rather their activity, the difference lies in their structure and not their sequence. Hence the answer can't be (B) or (D). Adaptations are made to broaden the conditions of survival. Hence E. coli would not limit it's survival by limiting its growth to warmer temperatures. Hence the answer is (A) the RNA polymerase subunits of the P. syringae strain probably have extra flexibility so that they can move more freely in colder temperatures.
Answer:
B. nitrogen-fixing
Explanation:
Nitrogen fixing bacteria are able to change pure nitrogen into ammonia compounds.
Nitrogen fixing bacteria are found in the soil close to the root of leguminous plants. They are get their own nutrition by chemosynthesis.
- They take nitrogen from the atmosphere in form of nitrogen gas.
- The nitrogen gas is converted into fixed nitrogen compounds such ammonia.
Answer:
1)When the oxygen level is low, carbohydrates break down for energy and produce lactic acid. Lactic acid levels rise with strenuous exercise or other conditions - such as heart failure, severe infection (sepsis), or shock - which reduces the flow of blood and oxygen throughout the body.
2) no gender differences in resting or peak blood lactate concentrations, nor in the rate of blood lactate removal of young adult men and women with similar aerobic fitness level expressed as ml.kg FFW1
