Answer:
Clear cutting can result in increased carbon dioxide levels in the atmosphere.
Explanation:
Clear cutting of trees increases the amount of carbon dioxide. Trees are useful in balancing the concentration of carbon dioxide in the atmosphere. They trap carbon dioxide that is used during photosynthesis in the manufacture of carbohydrates. When there is deforestation, the excess carbon dioxide rises to the atmosphere forming a blanket that traps excess heat which causes global warming or greenhouse effect. The excess heat warms the aerth surface.
Answer:
Met-Ser-Ser-Leu-Ser-Leu
Explanation:
mRNA have triplet codons and each triplet codon codes for an amino acid. An amino acid can be coded by many triplet codons but one amino acid can only code for a single amino acid.
AUG is a start codon that codes for initiator amino acid called methionine. Serine can be coded by UCU, UCC, UCA, UGC, AGU, AGC triplet codon. leucine can be coded by UUA, UUG, CUU, CUC, CUA, CUG.
So the codon sequence 5' AUG-UCU-UCG-UUA-UCC-UUG 3' will generate Met-Ser-Ser-Leu-Ser-Leu amino acid sequence.
Answer:
How long the dog runs without stopping
Explanation:
The dependent or responding variable in an experiment is the variable that is dependent on the changes made to the independent variable. It is also the variable that is measured or recorded in an experiment.
In this experiment where a student tests the effect of caffeine on dogs. Three groups of dogs were used for the test and they received water, 10mg caffeine and 50mg caffeine respectively. The different level of caffeine used is tested by recording how long each dog runs without stopping. Hence, how long the dog runs without stopping is the DEPENDENT VARIABLE.
Answer:
due to the rate of blood circulation
The name of the species that eliminated the wolves in Yellowstone so that they had to be reintroduced is <u>humans</u>.
In the olden times, people were unaware about the importance of natural ecosystems and the worth of each organism being part of an ecosystem. An expansion in an area caused the wild predators to come close to domestic livestock during the 1800's. The wolves began using these domestic animals as a source of nutrition. The humans, in order to protect their livestock, killed wolves.
It was as late as the 1970's when efforts started to being made to protect endangered species. These efforts caused the reintroduction of the wolves in Yellowstone.
