<em>2:4 homozygous recessive; 50% heterozygous.</em>
Explanation:
I will be using the letter B to represent dominant alleles and b to represent recessive alleles.
If a canary is heterozygous, that means that it will have (Bb). Hetero, means different, so it will <em>never </em>be both (BB) or (bb).
If the other canary is homozygous recessive, it will be (bb). Homo, means the same, so it will <em>never </em>be (Bb). If the canary were homozygous dominant, it would be (BB).
I made a Punnett square to figure out the ratio and the percentage that is being asked in the question. As you can see, if you bring down the alleles from both of the parents accordingly, you will get...
<u>2:4</u> of the offspring will be potentially <u>homozygous recessive</u>.
<u>50%</u> of the offspring will be <u>heterozygous</u>.
Answer:
Scientists throughly understand what dark matter is and what it does
New data could cause scientist to change their hypotheses about dark matter
Explanation:
The continental places around the Pacific Ocean have lot of volcanic activity.
Explanation:
The Pacific plate is an oceanic plate. It borders several continental plates. On all sides, the Pacific plate is subducting below the other plates. The subduction zones have resulted in intense geological activity along the boundaries, which are right next to the continental edges. Along the sides of the continents that are having a boundary with the Pacific plate there are lot of volcanoes and earthquakes.
- The boundary between the Pacific plate and the other plates around it makes up the Ring of Fire.
- The Ring of Fire stretches mostly on the edges of the continents, surrounding the Pacific Ocean, and it is the place where most of the volcanoes on Earth are located.
- The formation of volcanoes has influenced the topography of the edges of the continents, and all of them are mountainous along the coastlines.
- All of the volcanic activity and the subduction result in cracking of the crust and adjustment of it, resulting in release of lot of energy, or as we know it - earthquakes.

i think it’s the last one on question number one, and the first one on question two.
