Cold front brings a sudden drop in temperature sometimes with hail , thunder , and lightning . Warm fronts bring gentle rain or light snow , followed by warmer , milder weather . Stationary front brings a cold and warm air together and neither air mass has the force to moved the other . Occluded front brings a warm air mass that gets caught between two cold air masses .
My best explanation is
Some cancer is in blood and tissue and doesn’t form a tumor, such as leukemia. Therefore a usage of “chemotherapy” is needed.
Sorry if this isn’t a good explanation
Answer:
1. Light
2. production of large component from smaller components
Explanation:
In the given question, the meaning of the word Photo is light and the synthesis refers to the production and combining these words form photosynthesis. The literal meaning of photosynthesis will be the production of some compounds in the presence of light.
The word photosynthesis is used by the biologists to refer to a process taking place in the green plants which involve the light for the synthesis of energy-providing molecule glucose.
Thus, 1. The light and production of the large components are correct.
Sweating is the body's way of cooling itself. If you did not sweat, you could overheat the body and collapse from heat exhaustion.
Answer:
A. Glucose:
As lactose is absent will follow the glucose metabolism, so the lac repressor will hold tightly with the operator which leads to the prevention of transcription as RNA polymerase can not bind to promoter so no lactose metabolism.
B. lactose:
In the case or wild mutant lactose metabolism will occur as lactose is present, allolactose binds to the lac repressor thus the operator and promoter are free so transcription starts. The same result will be in all test except in the case of a mutant repressor.
C. glucose and lactose:
In this case, diauxic growth will occur. This growth takes place when two sugars are present in the media. The preferred sugar will be consumed first That is glucose. Then a lag phase will come which will be followed by the second sugar metabolism that is lactose. the given two cases :
Lactose will be metabolized first, as operator site mutation prevents repressor protein binding and thus will lead to the constitutive synthesis of lac operon in test B.
The same thing will happen, as in this case also, constitutive synthesis of lac operon will happen in test C.
Cultures grown in the presence of both glucose and lactose are metabolizing lactose. In the test (b) and (c) will be responsible due to constitutive synthesis of lac operon will happen.
