Answer:
Right now, I am in college for climatology, but before I decided on climatology, I was taking classes in Meteorology, the study of weather. So, I will answer your question. All meteorologists like to be right, but since the weather is so spontaneous, it is really hard to be right. Meteorologists use percentages because it helps them be professional. Also, because, different parts of the region where they are may or may not get the rain. I don't know where you are from, but I will use my hometown. In McAlester, Oklahoma, there may be a 70% chance of rain, but in another part of the region at Tulsa, Oklahoma ( which is 91 miles north of McAlester) there may be a 40% chance of rain. The difference in the percentages can vary from how stable the environment is, altitude, location, and terrain. That is two of the reasons why Meteorologists use percentages to predict weather.
Explanation:
Giraffes and Elephants: Giraffes have adapted a long neck over time letting them eat and access food allowing them to survive. If a dry season was unusually long they would succeed fine because they are able to eat and drink from the trees. Elephants have survived with similar tactics of eating higher up, they have rough skin allowing them to outlast the heat, and only need water after long periods of time.
Answer:
Let ‘Xᶜ’ be the recessive allele for colour blindness and ‘X’ be the normal (dominant) allele.
Since Abby's father was colour blind, Abby must be a carrier for the same.
Which means Abby's genotype would be ‘XXᶜ’.
Now, Ryan is not colourblind which means his genotype would be ‘XY’.
Now, talking about their daughter, she would inherit a normal ‘X’ from Ryan and either ‘X’ or ‘Xᶜ’ from Abby.
Which means she wouldn't be colourblind but she might be a carrier of the disorder.
XXᶜ × XY
⬇️ ⬇️
X, Xᶜ X
↘️ ↙️
XX , XXᶜ
Their daughter will have either XX genotype or XXᶜ genotype.
And her chances of being colourblind thus, becomes zero.
Answer:
A limitation of using hair as evidence from a crime scene is that hair can not be directly linked to a suspect. It is impossible to say that a hair sample came from only one specific person.
