( more people can answer this better then me)
Answer:
Choice A, BCAD
Explanation:
Recombination frequency is a number that describes the proportion of recombinant offspring produced in a cross. In other words, it tells us how often does crossing over happen between the loci of two observed genes. The bigger the RF is, the larger is the distance between two genes. That means that genes B and D (RF 14%) are the most distant ones, and all the others are located inbetween them. You have to sketch the order of genes based on how far away they are from each other.

Answer:
External respiration: CO2 diffuses into the blood
Explanation:
External respiration is also called the pulmonary gas exchange. It refers to the diffusion of O2 from the air in the alveoli of the lungs to blood in pulmonary capillaries and diffusion of CO2 in the opposite direction from the capillary blood into the alveolar air. External respiration in the lungs is responsible for oxygenation of deoxygenated blood coming from the right side of the heart. The oxygenated blood is then returned to the left side of the heart.
Answer:
Water is the common solvent of the body
Water is a polar, covalent molecule
The high heat capacity of water relates to its ability to absorb significant
amounts of heat before changing one degree celsius
.
Acids have a higher concentration of free H+ than are found in bases
Explanation:
Water is also called universal solvent because it can dissolve a large number of polar compounds due to its polar nature. In water, covalent bond is present between hydrogen and oxygen due to which partial positive charge occurs on hydrogen and partial negative charge appears on oxygen atom due to difference in electronegativity values. Acids has high concentration of proton (H+) while bases has high amount of OH- ions.
