Considering these statements;
F. the heart is composed of muscle tissue
G Hormones can trigger asthma attacks
H The rib cage expands to move air into the lungs
J blood cells can attackpathogens
The most appropriate statement that describes one possible interaction between the endocrine and the respiratory systems is G. Hormones can trigger Asthma attacks.
Endocrine systems releases hormones into the bloodstream so that one organ can communicate with another. Respiratory system brings in air to the lungs, where it diffuses into the bloodstream and also excretes carbon dioxide.
Answer:
Carbon monoxide consists of one oxygen and one carbon atom that’s why carbon monoxide is not an atom.
Explanation:
Answer:
The correct answer would be d) bacteria that make human insulin and a Bt corn plant.
An organism that contains and/or expresses a transgene or foreign gene is termed transgenic organism.
Bacteria that make human insulin contain and express human genes which code for A and B chain of insulin.
Similarly, Bt cotton is also a transgenic organism as it contains and expresses cry gene isolated from bacterium <em>Bacillus thuringiensis. </em>It provides pest resistance to the plant.
Thus, option d contains a pair of transgenic organisms.
200 million year to 550 million years old
The cell theory states that absolutely all living beings are composed of cells, for which all cells must contain the necessary structures to metabolize (nourish) and self-perpetuate (reproduce) as the cell nucleus, where the DNA is store.
Cell theory focused the efforts of biology on the cell as the minimal structure to sustain life.
- The vital functions of organisms take place within cells through biochemical processes, and are controlled by substances secreted by cells.
- Cells have diverse structures and delimited sectors that allow them to fulfill vital functions in the entire organism: birth, nutrition, metabolism, reproduction, growth, death.
- These processes also depend on important cellular structures, such as the cell nucleus, where the DNA of the entire species is contained.
Therefore, we can conclude that the cell theory allowed us to understand the dynamics and processes of the cell.
