I think the answer is B if I’m not mistaken
Where is the natural habitat at
Answer:
a population that is adapted to its current environment.
Explanation:
The theory of natural selection explains the development of adaptive features by organisms required to survive in their current environment. The theory supports the survival of the fittest idea whereby those organisms with the most equipped environmentally adaptive features survive. Theae features are also passed from parents to offspring on a bid to facilitate their adaptation to their current environment. This means different organisms develop features required for each of their present environment.
In eukaryotic cells the DNA is in the nucleus.
but in prokaryotic cells, it's in the
cytoplasm
good luck
Answer:
Respiratory System: The respiratory system's main job is to move fresh air into your body while removing waste gases.
Nostril: To warm air on inhalation and remove moisture on exhalation.
trachea: Serves as passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles.
bronchiole: To deliver air to a diffuse network of around 300 million alveoli in the lungs.
alveoli: To exchange oxygen and carbon dioxide molecules to and from the bloodstream during breathing.
pharynx: Helps the respiratory system by allowing air to make its way to the respiratory tract.
larynx: Produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.
lungs: To help oxygen from the air we breathe enter the red cells in the blood.
ribs: To aid respiration and help protect the lungs.
diaphragm: Contracts and flattens when you inhale. Creates a vacuum effect that pulls air into the lungs, and relaxes when exhaling.
