Abiotic are the non-living physical and chemical factors that can affect the ecosystem, such as amount of water, temperature, amount of sunlight, etc.
Biotic are the living organisms inside the ecosystem, and can include humans, animals, and plants.

I believe the answer is D) Eukarya
Autosomal dominant condition occurs when alleles of genes present on chromosomes in the autosomes (somatic) mask the effect of the other allele.
They can produce a light brown kid and the chances of producing this is 50%.
- Light brown color is dominant to black. A light brown male is mated to a black female, producing a black kid.
- For the two to produce a black kid which is in the recessive condition, the male has to be heterozygous for the condition (Bb).
Let light brown be (BB or Bb) and black be (bb)
Parents : B b x b b
Offspring genotype: Bb bb
Ratio: 1 : 1 (50%)

Answer:
1. The pathway of a red blood cell from the right ventricle to the brain is:
<em>Right ventricle → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → artery aorta → arterial vessels → brain
.</em>
2. The substance that forms hemoglobin in red blood cells when it passes through the lungs is oxyhemoglobin.
Explanation:
Red blood cells are structures present in the blood, whose function is to transport oxygen (O₂) and carbon dioxide (CO₂). This process requires travel throughout the body, through the blood vessels, and gas exchange at the pulmonary and tissue level.
1. A red blood cell in the right ventricle contains carbon dioxide and must pass to the lungs to be oxygenated. The route it takes from there includes Right ventricle (minor circulation) → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → (joining the major circulation) artery aorta → arterial vessels → brain
.
2. The red blood cell or erythrocyte contains a molecule, called hemoglobin, which has an iron core that allows it to bind to O₂ and CO₂ in order to transport them. The affinity for one molecule or another depends on the presence of a certain gas in a certain place.
When the red blood cell passes through the lungs, the concentration of O₂ is higher than CO₂, so the latter is released and O₂ binds to hemoglobin, a conjugation that is called oxyhemoglobin.
