When muscles are unchallenged, they turn weak, energy systems start degenerating, joints stiffen, and low back pain decreases. Hence, all the options are correct except option E.
Muscles can be challenged by performing various physical exercises like performing cardio, lifting heavy loads, etc. You can also increase the intensity of your exercises as you get stronger over a course period of time. This would increase your muscle endurance and make them stronger.
On the other hand, when muscles are left unchallenged, they turn sedentary. Muscles can deteriorate and lose density when they aren't used. Joints may stiffen and energy systems may start to break down as a result. Additionally, low back pain may lessen. But it's incorrect to say that when muscles aren't pushed, bones lose density.

The emergence of very diverse species of house pets (such as different types of birds) is an example of __________.
The emergence of very diverse species of house pets, such as different types of birds, is an example of selective breeding or artificial selection.
Selective breeding, also known as artificial selection, is a method used by humans to selectively develop specific phenotypic traits (characteristics) in animals and plants by deciding which male and female animals or plants will reproduce sexually and produce offspring together. While domesticated plants are recognised as variations, cultivars, or breeds, domesticated animals are known as breeds and are often bred by a professional breeder. A crossbreed is created when two purebred animals of different breeds mate, while hybrids are the name given to crossbred plants. Major crops are often the product of specialists; amateurs and professionals may both breed flowers, vegetables, and fruit trees.

Green skin is common in science fiction, from little green men to Hera Syndulla from "Star Wars Rebels" to Gamora from "Guardians of the Galaxy." But what if green skin were not just for fictional aliens? If humans had green skin, for instance, what if it granted us the ability to perform photosynthesis, which plants use to live off of sunlight?

Here in total of 50 alleles, 20 alleles are B(black) and 30 are b (brown). How many of each allele would be present in a total of 100 alleles?
If we have a total of 50 alleles, with 20 alleles being B (black) and 30 alleles being b (brown), we can calculate the number of each allele present in a total of 100 alleles by maintaining the same proportion.
To do this, we first need to determine the ratio of black alleles (B) to brown alleles (b) in the initial 50 alleles.
The ratio of B to b:
B:b = 20:30 = 2:3
Now, we can apply this ratio to calculate the number of each allele in a total of 100 alleles.
For black alleles (B):
If the ratio of B:b is 2:3, we can represent it as 2x:3x, where x is a common multiplier.
So, 2x represents the number of black alleles in the new total of 100 alleles.
To find the value of x, we can set up the following equation:
2x = 20 (since there were originally 20 black alleles)
Solving the equation:
2x = 20
x = 10
Now we can calculate the number of black alleles (B) in a total of 100 alleles:
2x = 2 * 10 = 20
Therefore, there would be 20 black alleles (B) in a total of 100 alleles.
For brown alleles (b):
Since the ratio of B:b is 2:3, the number of brown alleles can be represented as 3x.
To find the value of 3x, we can multiply x by 3:
3x = 3 * 10 = 30
Therefore, there would be 30 brown alleles (b) in a total of 100 alleles.
In summary, in a total of 100 alleles, there would be 20 black alleles (B) and 30 brown alleles (b), maintaining the same proportion as in the initial 50 alleles.

Just considering one locus (a specific location on a DNA strand), evidence at a crime scene shows a genotype of 5, 9 STR repeats at this locus. The general population frequencies for the alleles 5 and 9 are 0.100 and 0.300, respectively. How frequent would the genotype 5, 9 be expected to be in the general population
Answer:
0.1 x 0.3 = 0.03 = 3%
Explanation:
Assuming a process of random mating in the population, it is possible to infer that the genotype frequencies will be the product of the allele frequencies. The random mating is one of the postulates of the Hardy-Weinberg Law, which is widely used in population genetics to estimate genotypic frequencies when populations are expected to be in an equilibrium state (it is also expected by default in human populations). In this case, the genotype frequencies will be certainly low (3%), thereby this locus may be useful to investigate a police case.

Identify and describe patterns of how air masses interact and change over time
Air masses interact and change over time in a variety of ways. The interactions between air masses form the basis of weather systems and global weather patterns.
Air masses move in response to pressure differences, temperature differences, and other factors. As air masses interact, they can change in temperature, humidity, and other characteristics. Air masses can also mix, creating fronts and other weather systems. As air masses move, they can bring wet or dry conditions, warm or cold temperatures, and other changes in the atmosphere.
Over time, these interactions can create longer-term shifts in global weather patterns, such as El Niño or La Niña. By studying how air masses interact and change over time, meteorologists can better understand and predict global weather patterns.
