how has selective breeding contributed to a wide variety of dog breeds?
Answer:
In the same way that inbreeding among human populations can increase the frequency of normally rare genes that cause diseases, the selective breeding that created the hundreds of modern dog breeds has put purebred dogs at risk for a large number of health problems, affecting both body and behavior.

A frog that is dominant for its light green color mates with a brown frog and produces one small brown frog. How is this possible if the green color is dominate?
Answer:
The dominant (light green) parent was heterozygote for the trait
Explanation:
According to Gregor Mendel in his law of dominance, an allele is said to be DOMINANT if it masks the phenotypic expression of another allele in a gene. The allele being masked is called RECESSIVE allele. In this case of a frog whose allele for light green color is dominant over the allele for brown color, the light green color allele (G) is dominant while the brown color allele (g) is recessive.
However, in a cross between that have light green frog and a brown frog, a small brown frog is produced. This is possible despite the green color being dominant because the genotype of the light green dominant parent is HETEROZYGOUS i.e. it contains both light green (dominant) allele and brown (recessive) allele.
Hence, when a gamete with recessive allele (g) is produced by the heterozygous light green frog (Gg), it mates with a recessive allele from the brown frog (gg) to produce a brown offspring (gg).

Equations for help:
K= C + 273
C= 5/9 (F - 32)
F= (C * 9/5) + 32
Answer:
9) 75.2°F is less that 82°F so the water is not warm enough for Emma to swim in.
10)Since, 102.2°F is greater than 100°F, Stephen can't go to school today.
Explanation:
9) First, we want to find out 24°C converted to Fahrenheit
What we want to find Equation
24°C = ?°F F= (C * 9/5) + 32
Second, we have to input our number into our equation
F = (24 × 9/5) +32
Next, we have to use the PEMDAS strategy (ask in the comments if you don't understand!)
24 × 9/5 =
24 × 9 = 216 216÷5 = 43.2
1 × 5 = 5
Now, we can't forget to add 32!
43.2 + 32 = 75.2°F
24°C = 75.2°F
75.2°F is less that 82°F so the water is not warm enough for Emma to swim in.
10) For this problem, I'm going to just show the math, so if you have any questions feel free to ask in the comments!
Step 1) 312 = C + 273
-273 -273
Step 2) 39 = C or C = 39
Step 3) F = (39 × 9/5) + 32
Step 4) F = (351/5) + 32
Step 5) F = 70.2 + 32
Step 6) F = 102.2
Since, 102.2°F is greater than 100°F, Stephen can't go to school today.(and should think about getting a regular thermometer ;)
Hope this Helps! :)

16. In which of the following situations are the phenotypes of F2 offspring expected to follow
the ratio of 9:3:3:1?
a. monohybrid cross for two unlinked traits
b. a monohybrid cross for two closely linked traits
c. a dihybrid cross for two unlinked traits
d. a dihybrid cross for two closely linked traits
Answer:
C
Explanation:
The F2 offspring of a cross would follow the ratio of 9:3:3:1 only if the cross is a dihybrid for two unlinked traits.
There is nothing like a monohybrid cross for two traits. A cross involving two traits is a dihybrid cross. Hence, options a and b are out of the equation.
A dihybrid cross for two closely linked traits would produce F2 offspring in another ratio that is different from 9:3:3:1 depending on the linkage map.
Hence, the correct option is C.

what happens when a person is infected with live pathogens
Answer:Once you're infected, viruses invade host cells within your body. They then use the components of the host cell to replicate, producing more viruses. After the replication cycle is complete, these new viruses are released from the host cell. This usually damages or destroys the infected cells.

Answer:
Here's a better answer. I know its late though.
Explanation:
There are multiple lines of evidence that provide support for common ancestry and evolution; this would be homologous features of anatomy and embryology and fossil records.
In comparative anatomy, there are many similarities between species because all life is related. Homology is similarities seen because of the ancestry of features or genes in an organism. Similarities can show descent from common ancestors and similarities can be seen in body structures, development, and DNA. Homologous structures are similar traits found in two different species that are the result of having a common ancestor. These structures are similar but may have different functions. An example of this might be the homologous structures in the limbs of humans, cats, whales, and birds. And then there are analogous structures, which similarly is that the structure of different species are similar because the trait is advantageous, not because they are related. An example of this is sharks and dolphins having similar fins. Along with anatomy is Embryology. Different species can have similar embryos because they come from a common ancestor. They may start with the same developmental plan but change drastically as they grow up. An example of this is seen in the early stages of development between fish and chicken embryos.
Next up, the fossil record provides evidence that supports common ancestry and evolution. The fossil record provides us with visual evidence for evolution. The fossil record directly allows us to pinpoint if there are any similar structures amongst organisms and see if there are any vestigial structures from ancestors that remain in organisms that still roam today. The fossil record depicts evolutionary change over the past four billion years, which can be seen through transitional forms, increasing complexity of life, and geographical distribution. Transitional forms are fossils that show intermediate states between an ancestral species and its evolutionary descendants. Increasing complexity is seen as life on earth becomes more complex. That and geographic distribution which has been studied closely and found that the continents have moved over time and that the fossil record reflects this movement. Fossils of different animals can be found on different continents around the world due to continental drift.

17. What causes evaporation?
O Air that is unsaturated with water vapor comes into contact with the surface of the water
O Air that is cooler than the water comes into contact with the surface of the water
O Air that is warmer than water comes into contact with the surface of the water
O Air that is supersaturated with water vapor comes into contact with the surface of the water in
Evaporation occurs when air that is warmer than water comes into contact with the water's surface, hence option A is correct.
What is evaporation?As a liquid transforms into a gas, evaporation, a sort of vaporization, occurs on the liquid's surface. For instance, a high concentration of the evaporating substance in the surrounding gas significantly slows down evaporation when humidity affects the rate of evaporation of water.
It takes in moisture from garden soil as well as the biggest lakes and seas, and the level of the water will decrease when it is heated by the sun.
Therefore, solar energy, or heat from the sun, is what causes the evaporation process to occur, hence option A is correct.

Fossil records are described as the position of found fossils all through the surface or the layers of the earth. The older the fossils are, the deeper it is found. Fossil records are also considered to be gathered information about the total number of the discovered fossils and the data obtained from them.
Fossil records are important guides to determine how life existed before. If you are to assemble a fossil, you will be able to see and tell the evolutionary changes that happened over the past years. Fossil records are evidences pointing out that life before is totally different from now.
Index fossils are fossils that are common yet were only present for a brief time. By comparing a rock layer to other rock layers, index fossils enable scientists to determine the relative age of a rock layer. Organisms that are still alive today yet have undergone little alteration over millions of years are known as living fossils.
