The answer to this question is
A Hypothesis allows you to make a prediction about future experiments , But a prediction is more specific and Prediction are using forms like ("IF" and "Then") and Hypothesis is more like a regular sentence
Your Welcome :)
Answer:
Cystic fibrosis
Explanation:
X- linked trait may be defined as the trait that is located on X chromosome or the inheritance of the trait is based on the X chromosome. The disorders associated with X-linked trait is known as sex linked disorder.
Cystic fibrosis is an autosomal recessive disorder that affects the digestive system, lungs and liver. The homozygous recessive condition is responsible for the disease cystic fibrosis. Hence, cystic fibrosis is not an X-linked trait.
Thus, the correct answer is option (2).
1. Tropical rainforests 2. Savanna 3. Temperate 4. Desert 5. Taiga 6. Tundra 7. Estuary 8.fresh water 9. Marine
a) when lactose is absent, the repressor is active, RNA Polymerase cannot bind to the promoter and the structural gene are not formed.
b) when lactose is present, the lac repressor is inactive, RNA Polymerase can bind to the promotor and the structural genes are formed.
Explanation:
The lac operon in E.coli has genes required for lactose metabolism.
It is expressed only when lactose is present in the medium and glucose is absent.
According to the glucose and lactose level the operon is switched on or off.
The lac repressor or allolactose and catabolite activator protein is present in lac operon.
Glucose is the primary source of energy but bacteria loves to fuel down lactose. To use lactose as an energy source lac operon works.
a) when lactose is absent, the repressor is active, RNA Polymerase cannot bind to the promoter and the structural gene are not formed.
b) when lactose is present, the lac repressor is inactive, RNA Polymerase can bind to the promotor and the structural genes are formed.
The lac repressor is a protein that inhibits transcription of lac operon in the absence of lactose.
I think option C is correct because snakes r not omnivores they eat insects not plants so option D and A are wrong
In option B eagle is carnivore
Fish can be omnivores, but some species are carnivores or herbivores. In general, a fish's diet is determined mostly by its habitat and what food is available. Most species have a preferred diet but will eat outside of that if necessary for survival.
Bear can also b omnivore
