Answer:
how meiosis affects chromosome number
Answer:
1:1 (brown:blonde)
Explanation:
Brown hair color (B) is dominant over blonde hair color (b).
Heterozygous parent will have the genotype Bb
Homozygous recessive parent will have the genotype bb.
Crossing hetezygous parent with homozygous recessive parent:
Bb x bb
Progeny: Bb, Bb, bb, and bb.
2 Bb brown hair
2 bb blonde hair
Phenotypic ratio = 1:1 (brown:blonde)
The correct answer is 1:1 (brown:blonde).
Answer:
Explanation:
Haemoglobin in the red blood cells which is one of the components of the circulatory medium, the blood, has a great affinity for oxygen hence transports it around the body during circulation. It is the circulatory system that carries both oxygenated and deoxygenated blood around the body, between the lungs and the heart. The circulatory system takes blood with carbon dioxide to the lungs where oxygen that entered into the body through the nostrils will be exchanged with carbon dioxide in the alveoli. Consequently carbon dioxide will go out of the body through the nostrils via the trachea and haemoglobin in the red blood cells in the blood( blood capillaries) will
carry oxygen which is transported around the body.
Answer:
Energy is said to flow in a "one-way stream" through an ecosystem. In your own words, describe what that means. Energy is not recycled. Energy enters an ecosystem and flows through a food chain, but it is not reused, it is lost as heat.
Hope the answer helps:)
