Answer:
If both parents are heterozygous, there is a 1/4, 25%, 0.25 chance that the baby turns out albino.
Explanation:
Using A as the dominant allele and a as the recessive allele, I made a quick Punnett Square and attached it below. The outcomes are AA, Aa, Aa, and aa. I hope it helped! :]
Explanation:
Water enters the atmosphere through three processes: evaporation, transpiration, and sublimation.
ANSWER: the organisms in the air, on land, and in the water
REASONING: A <u>biosphere</u> is defined as an ecological system that comprises of all living things, and their relationships and interactions with the living and non living things around them. The first three answers only considers certain parts of the system, and the correct answer considers all parts.
We know that Hardy-Weinberg conditions include the following equations:
where 
And where p = dominant, and q = recessive; this means that 
is equal to the homozygous dominant, 
is the heterozygous, and 
is the homozygous recessive .
So we have 100 total cats, with 4 having the recessive white coat color. That means we have a ratio of 
or 0.04. Let that equal our 
value.
So when we solve for q, we get:
Now that we have our q value, we can use the other equation to find p:
So then we can solve for our heterozygous population:
This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:
So now we know that there are 32 heterozygous cats in the population.
"The earliest evidence of life on Earth comes from fossils discovered in Western Australia that date back to about 3.5 billion years ago. These fossils are of structures known as stromatolites, which are, in many cases, formed by the growth of layer upon layer of single-celled microbes, such as cyanobacteria. (Stromatolites are also made by present-day microbes, not just prehistoric ones.)
The earliest fossils of microbes themselves, rather than just their by-products, preserve the remains of what scientists think are sulfur-metabolizing bacteria. The fossils also come from Australia and date to about 3.4 billion years ago
Bacteria are relatively complex, suggesting that life probably began a good deal earlier than 3.5 billion years ago. However, the lack of earlier fossil evidence makes pinpointing the time of life’s origin difficult (if not impossible)."
