The digestive works to break down food eaten before exercising.
The digestive system is responsible for the process of digestion, which involves the breaking down of the consumed food into smaller parts which can be absorbed by the body. This system is comprised of the gastrointestinal tract and several organs participating in digestion, which are the tongue, salivary glands, pancreas, liver, and gallbladder.
The circulatory takes in the nutrients obtained from the food.
The circulatory system (also known as cardiovascular system) is responsible for circulating blood through the body and transporting nutrients and many other chemicals. The heart and the lungs are two critical components of this system since blood flows through the lungs and oxygenates. This oxygenated blood is pumped through the heart to the rest of the body.
The body sweats as a mechanism to cool off, because the excretory is working to flush out toxins.
The excretory system is responsible for removing excess and unnecessary materials from the body fluids of an organism. The main organ system involved in this system is urinary system, however, excretion is also achieved through breathing and sweating.
K! i luv mad libs by the way! u just need to tell me what part of speech!!
The complete question is:
An individual with genotype AA is crossed to an individual with genotype aa at the same genetic locus. The allele A is dominant to the allele a.
If the offspring are interbred through two generations, what is the predicted ratio of phenotypes in the F2 generation?
9:16 (dominant:recessive)
9:7 (dominant:recessive)
3:16 (dominant:recessive)
1:3 (dominant:recessive)
Answer:
3:1 dominant:recessive phenotype ratios
Explanation:
The recessive phenotype disappears in the F1 generation, but it reappears in the F2 at a ratio of 3:1, being therefore dominant:recessive
B) is the correct answer. The flu virus does not have the same genetic makeup each year as with each individual it infects its rapidly mutating.
