What are the chances a
heterozygote passes on
either a dominant or
recessive allele?
Answer:
A parent with one copy of a dominant allele and one recessive coded Ww for the widow's peak is called heterozygous for a trait and has a 50 percent chance of passing on the dominant allele to each of his or her offspring, regardless of the gene inherited from the other parent.

How is the water and boiling point of water useful to us
Answer:
The boiling point of water can be used to illustrate the importance of hydrogen bonds in living systems. The boiling point of a compound is the temperature at which a liquid becomes a gas. When the temperature is high enough to separate the individual molecules from each other, they boil, or become a gas.

Which of the following is NOT one of Darwin's conditions for natural selection to occur?
Answer:b
Explanation:
What ideas were changing in the scientific community at the time of Darwin's travels? How might those new ideas influenced Darwin?
Answer and Explanation:
At the time of Darwin's travels, the scientific community was beginning to abandon ideas linked to creationism to adopt more scientific and testable concepts, less linked to religiosity. Darwin was very influenced by these new concepts and decided to study a way to apply them to the biological diversity that planet earth presented. He wanted to explain this diversity through scientific data, obtained by experiments and logical reasoning, without the interference of creationist concepts and that would show how life on earth changes over the years and how species of living beings were created. This was one of the kicks that made him start his travels and his studies on biological evolution.

What prevents blood from circulating backward in veins?
A.valves
B. capillaries
C. lungs
D. heart
Answer:
A.Valves
Explanation:
The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium. As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.

why is studying climate change a scientific challenge? ( please be specific and
go into depth)
Answer:
Climate change is already happening: temperatures are rising, drought and wildfires are starting to occur more frequently, rainfall patterns are shifting, glaciers and snow are melting and the global mean sea level is rising. These ever-changing trends mean that scientists have to be well acquainted with all this which requires a great deal of understanding and patience.
The political interests in research often limit the results and many a time misleading
Data for climate research is in many instances difficult to access, often at a price, and according to the source and type of data, the formats for retrieval can be very different. In addition, data may not be available for the same time and space scales. There is often an incompatibility between socio-economic and physical data, both necessary for climate modeling efforts because data collection is generally carried out by different agencies for different purposes. This means scientists have to analyze this data as useful and then research on it.
