Explanation:
DNA is tightly wound around histones,forming nucleosomes. Nucleosomes are tightly coiled and supercoiled to form chromosomes.
What change in the mass number of a nucleus occurs when the nucleus emits an alpha particle?
Answer:
Protons are positively charged. When a nucleus emits an alpha particle, these changes happen: the mass number decreases by 4. the atomic number decreases by 2.

What is the conversion factor from km. to ft.? If Joe traveled 12 kilometers, how many feet did he travel?
Answer:
The distance traveled by Joe in feet is 39,372 ft:
Explanation:
The conservation factor from km to Ft is 1 km = 3280.84 feet.
* In order to convert the value-form km to ft then we multiply the given value of the length by 3281.
*We are given that:
*Distance traveled by Joe = 12km
*Distance in feet = 12×3281
*Distance in feet = 39,372 ft
**Thus, the Distance traveled by Joe in feet is 39,372 ft.
The conversion factor from kilometers to feet is 3280.84 feet/kilometer. This means that there are 3280.84 feet in every kilometer.
So, if Joe traveled 12 kilometers, he traveled 12 * 3280.84 = 39370.08 feet.
1 kilometer = 3280.84 feet
12 kilometers = 12 * 3280.84 feet = 39370.08 feet
Therefore, Joe traveled 39370.08 feet if he traveled 12 kilometers.

which is a wildlife species category that state resource agencies may use
Wildlife species are defined as undomesticated animal, plant, or organism that grows in the wild and are not introduced to humans. The species that can be used by the state resource agencies are large mammals, small mammals, birds of prey, and waterfowl.
The animals that can be hunted legally must be:
The animal can be used as food and should be useful. The population of the animals should be high. The hunters should have a challenge while hunting them.Also, some species labeled as endangered must be protected by law. These species are on the verge of getting extinct and are present in the least numbers to harvest.
Thus, the state agencies may use large mammals, small mammals, and waterfowl.

Fill out the data table below with the range of each factor that will produce the optimal number of oxygen bubbles.
The optimal ranges for the formation of oxygen bubbles vary between each plant, however, only water, c02, and temperature are limiting factors for photosynthesis.
This question is based on observations made during the course of an experiment designed to measure the optimal ranges at which oxygen bubbles form, given that these are an indication of photosynthesis.
Due to this, the information given will be generalized. Firstly, there is no exact optimal range of light for the formation of oxygen bubbles (photosynthesis) given that this is not a limiting factor.
Excess of light will have no effect on photosynthesis, only the lack of light can cause negative effects, therefore any light past the minimum threshold is fine.
On the other hand, water, light, and C02 are in fact limiting factors and have optimal ranges. For water, this optimal range varies greatly and therefore I cannot offer a general value, but an excess of water will "drown" plants by not allowing the formation of air pockets in the soil.
C02 sits at an optimal range of 1,000-1,300ppm for the best results. Lower concentrations cause a lower rate of photosynthesis given that it is the primary substrate for the process to begin. At too high levels, plants will have to adapt which can slow the process.
Finally, temperature is also a limiting factor for photosynthesis. Its exact value cannot be given since it varies greatly between plant species.
However, in general, terms, since it is an enzyme-dependent reaction, we can apply the general temperature at which enzymes function best which is around 37 degrees.

Answer:
"DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect." information from a website so reword it a bit and you should be ok.
In the process of genetic profiling/ data fingerprinting, genetic profiling is a process that can be compared between two people/samples.
What is genetic profiling?DNA profiling compares only the most variable sections of DNA, which has an advantage over whole genome sequencing when seeking to identify genetic changes between two individuals.
In the field of biology known as comparative genomics, genome sequences from various species—including humans, mice, and a broad variety of other organisms—from bacteria to chimpanzees are compared.
"DNA fingerprinting is a lab method used to connect biological evidence to a defendant in a criminal investigation. A DNA sample from a suspect is compared to one acquired from a crime scene. The evidence originated from that suspect if the two DNA profiles match.
Therefore, genetic profiling is compared between two people/samples.

Blood leaves the heart through the pulmonic valve, it then moves through the pulmonary arteries which branches to the left and right lungs.
When the deoxygenated blood reaches the lungs, it is then oxygenated and returns to the heart through our pulmonary veins.
