The kingdom would be Plantae because it has membrane bound organelles as well as green chloroplasts, and a nucleus.
The gas exchange during cellular respiration involves oxygen moving into cells and carbon dioxide moving out of cells.
During gas change oxygen actions from the lungs to the bloodstream. on an equal time, carbon dioxide passes from the blood to the lungs. This happens within the lungs among the alveoli and a network of tiny blood vessels known as capillaries, which might be located in the walls of the alveoli.
Three strategies are critical for the switch of oxygen from the out of doors air to the blood flowing through the lungs: airflow, diffusion, and perfusion. ventilation is the manner through which air moves in and out of the lungs.
The lungs and respiratory system permit us to respire. they create oxygen into our bodies (called a concept, or inhalation) and send carbon dioxide out (referred to as expiration, or exhalation). This alternate of oxygen and carbon dioxide is referred to as respiratory.

n a cross between two heterozygous individuals, the offspring would be expected to show a 3 : 1 ratio. For example, in Case 1, three-fourths of the individuals would have red (wild-type) eyes, and one-fourth would have sepia eyes.
If there are 44 offspring, how many are expected to have red eyes?
We expect three-fourths to have red eyes.
<span>34</span> of 44 = 33
If there are 44 offspring, how many are expected to have sepia eyes?
<span>14</span> of 44 = 11
Now you are ready to calculate chi-square.
Answer:
Explanation:
Immunity to a disease is achieved through the presence of antibodies to that disease in a person's system. Antibodies are proteins produced by the body to neutralize or destroy toxins or disease-carrying organisms. Antibodies are disease-specific. Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system's antibodies and other cells to target the invader. A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response.
These molecules are called antigens, and they are present on all viruses and bacteria.
False, pernicious anemia may take up to 5 years to show symptoms. However, the oxygen starts to get depleted within the first 6 months in thalassemia major.
Pernicious anemia:
In this condition, the body is unable to absorb vitamin B12 which leads to lowered amount of red blood cells which are responsible for carrying oxygen throughout the body. It is an autoimmune disease in which antibodies attack their own cells in the lining of the stomach which affects the absorption of vitamin B12. The symptoms of pernicious anemia are dizziness, fatigue, diarrhea, constipation, breathlessness, and loss of appetite. The depletion of oxygen is seen in thalassemia major within 6 months.
