Answer:
Genotypic ratio = 1 Bb: 1 bb
Phenotypic ratio = 1 black rabbit : 1 brown rabbit
Explanation:
This question involves a gene coding for hair color in rabbits. The allele for Black hair (B) is dominant to the allele for brown hair (b).
According to this question, a black rabbit whose mother is brown haired (bb) is crossed with a brown hair rabbit. This means that the black rabbit will have a genotype 'Bb' while the brown rabbit will have a genotype 'bb'. Each parent will produce the following gametes:
Bb - B and b
bb - b and b
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Bb, Bb, bb and bb
This means that the;
Genotypic ratio = 1 Bb: 1 bb
Phenotypic ratio = 1 black rabbit : 1 brown rabbit
Answer: b) a chemical reaction between carbohydrates and oxygen to produce carbon dioxide, water, and heat energy
Explanation:
Based on the options, I assume that this is talking about the process of respiration. Respiration allows living things to produce energy by reacting carbohydrates with oxygen.
This results in the release of energy in the form of heat in a cell and also the formation of carbon dioxide and water. This type of respiration is known as Aerobic respiration.

![Q = 375\,cal](https://tex.z-dn.net/?f=Q%20%3D%20375%5C%2Ccal)
Explanation:
The quantity of heat transfered from the jellybean to the water is:
![Q = \rho\cdot V \cdot c\cdot \Delta T](https://tex.z-dn.net/?f=Q%20%3D%20%5Crho%5Ccdot%20V%20%5Ccdot%20c%5Ccdot%20%5CDelta%20T)
![Q = \left(1\,\frac{g}{cm^{3}}\right)\cdot (15\,cm^{3})\cdot \left(1\,\frac{cal}{g\cdot ^{\circ} C} \right)\cdot (25\,^{\circ}C )](https://tex.z-dn.net/?f=Q%20%3D%20%5Cleft%281%5C%2C%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%7D%5Cright%29%5Ccdot%20%2815%5C%2Ccm%5E%7B3%7D%29%5Ccdot%20%5Cleft%281%5C%2C%5Cfrac%7Bcal%7D%7Bg%5Ccdot%20%5E%7B%5Ccirc%7D%20C%7D%20%5Cright%29%5Ccdot%20%2825%5C%2C%5E%7B%5Ccirc%7DC%20%29)

Answer: for question 4, the answer would most likely be movement of air, water and rock
Explanation:
Answer:
The elements in each group have similar chemical properties.
Explanation:
This is correct because all elements in a group have a similar electron configuration in the outer most shell, therefore they will have similar chemical properties.
