Answer:
(C) The main predator of these fish is another species of fish on which alligators also prey.
Explanation:
The ecosystems are complex systems, and removing one species of them, always has a chain reaction and affects the population of the other species, be it in a positive or negative manner. In this case, the alligators prey upon fish, multiple different species. The alligators though have been removed from the ecosystem, thus the apex predator exists no more. This has opened up the top predator niche in the food chain in this particular ecosystem. The predatory fish species had no predators of its own, so its population increased, thus it needed more food, and that food was obtained by hunting the other fish species, resulting in a decline in the population of the other species of fish. Only when the carrying capacity is reached in the ecosystem for the predatory fish, the population of the other fish will stop declining.
Answer:
carbohydrates
Explanation:
Sucrose is a sugar, and sugars are a type of carbohydrate.
Answer: Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).
Explanation:
Answer:Karyotyping is a laboratory procedure that allows your doctor to examine your set of chromosomes. “Karyotype” also refers to the actual collection of chromosomes being examined. Examining chromosomes through karyotyping allows your doctor to determine whether there are any abnormalities or structural problems within the chromosomes.
Explanation:
Answer:
b. FD
d. Fd
c. Dd
h. dd
Explanation:
From the given information:
We are given a dihybrid cross that comprises two traits. The crossing exists between two heterozygous white disc-shaped traits i.e. FdDd.
If the parent self crossed, the gamete combinations for the F1 generation are:
F d
D FD Dd
d Fd dd
Therefore, the gametes combinations are four potential and feasible combinations of FdDd that can enter into the Filial generation crossing.
