Answer:
The Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go. It Filters out waste from food and pushes it through intestines and out the body.
Explanation:
As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
Answer:
d. 28,650 years
Explanation:
Since 14C has a single half-life of 5,730 years
The number of years that is going to make up 5 half-lives for 14C will be;
5,730 years × 5 = 28,650 years
Answer:
It is likely that the genomic sequences that were used did not enable to properly observe the evolutionary relationships among the species analyzed
Explanation:
The homology level between the genomic sequences may be too low to separate species that are phylogenetically related. In these cases, it is necessary to make a genetic analysis of the sequences that are used before the phylogenetic analysis
Answer:
the overlapping decreases between the thin and thick filaments.
Explanation:
When w extend our hand or arm to the full and try to lift any heavy object, we are unable to lift the object inspite of applying all our force. We struggle hard to lift the object with our fully extended arm because when we extend our arm fully it decreases the overlapping of our thin and the thick filaments of our muscles which makes it difficult to lift. In other words, the resting length of our arm is the optimal length to generate force.
