Inhaling carbon monoxide reduces the ability of red blood cells to carry oxygen. This can lead to brain damage. The respiratory, circulatory and nervous systems <span>interact in this situation.</span>
Answer: if i want to breed a rose and i don't have a certain kind of rose, i have to cross between them until i have a kind of rose that express the phenotype i was looking for. Once i've got it, i'll try to cross it with another rose and generate more species like that to cross with the rose that express the phenotype, this favors to generate a specie that have a pure phenotype.
Explanation: The answer is explain by the Mendel's laws.
Mendel's second law:
if you have two roses that are heterozygous and you cross them, their offspring have a 25% probability of generating a homozygous phenotype for a certain recessive characteristic (such as the rich smell of roses that is not a dominant character), 50% of generate heterozygotes with a dominant phenotype, and 25% generate other homozygotes with a dominant phenotype.
Once the offspring with the recessive homozygous character are obtained, it is possible to start making crosses between those of a recessive nature and there Mendel's first law applies
All the homozygous recessive individuals that are crossed will have a 100% homozygous recessive offspring.
Also, if you cross heterozygotes with another heterozygotes the offspring will be 100% heterozygotes
Answer:
Explanation:
Different materials will change temperature at different rates when exposed to the same amount of heat. This is because the different materials absorb heat at different rates.
Answer:
The seafloor is only 180 million years old due to the process of subduction. The floor of the sea's tends to get colder and denser with the passage of time. At a certain time, the seafloor becomes so dense that it sinks in the upper mantle. The Earth's crust cannot undergo this process and hence has oldest rocks. We can say that the seafloor is less than 180 million years old because it is typically recycled back into the mantle of the Earth.
