The right answers are complete gut and one-way gut.
Food is ingested by the mouth, where it is chewed and then thrown into the esophagus during swallowing.
After, there is food in the stomach
Then there is digestive absorption of nutrients in the small intestine
After that, Waste disposal and reabsorption of water in the colon (large intestine)
And finally, stool passes through the rectum (anus), where it is stored before defecation, induced by a reflex mechanism.
When you cross two heterozygotes with the genotype Aa, the offspring will be: <span>Parents: Aa x Aa</span>
<span>F1 generation: AA Aa Aa aa</span>
<span>This means that ½ of the offspring will be heterozygous, ¼ will be homozygous (dominant) and ¼ will be homozygous (recessive).</span>
A harmful mutation will harm the organism, a helpful will help the organism to survive, and a neutral will not affect the organism.Lol I feel like a nerd
Answer:
Radiation leads to mutations that causes genetic drift and decrease fitness.
Explanation:
Radiation is responsible for changing or altering the DNA sequence within a cell.
Radiation either causes mutation or it leads to cell death.
Most of the ionizing radiation causes mutation within the deep inside of our cells which eventually leads genetic drift which means change in the frequency of the allele in a population over time.
Beneficial mutation confer advantage to the organism. But in this case, the mutation is not beneficial and decreases the fitness of the rodent organisms.
