By the mother digesting it
1/2.
the gene Rr separate to R and r.
the gene rr separate to r and r.
then they mix, turn to
Rr, Rr, rr, rr.
because wrinkled gene r is recessive, so only rr would be wrinkled. the probability would be 2/4=1/2.
Answer:
D. Psychrophile
Explanation:
Psychrophiles or cryophiles are a type of extremophiles i.e. they live in extreme environment. They grow well in low temperatures ranging from -20 to +10 degree Celsius.
Here, the bacteria was incubated at different temperatures. It did not show growth at standard incubation temperature of 37°C which indicates that it might be an extremophile preferring either very hot or very cold environment. But it also did not show growth at 50°C which means that it does not survive well at high temperature.
Lab bench top has generally colder surface compared to the surrounding environment and a little growth was observed there which indicates that this bacteria might require cold temperature for growth. The result was finally confirmed with abundant growth observed inside refrigerator which is only possible if it is a psychrophile.
i think the answer is D.) chloroplast
Answer:
Mitochondria
Explanation:
This is where the citric acid metabolic pathways of cellular respiration occur. After the glycolysis process happens in cell cytoplasm to form pyruvate from glucose molecules, the pyruvate is converted to acetyl-CoA that enters the mitochondria for the TCA cycle. The TCA produces more ATPs from the energy molecule. The carbon atoms will ultimately be expelled from the cell as carbon dioxide.
