Answer: Option D " all of the above "
Explanation: DNA can be a great source of information when used as a forensic evidence. This technique has many advantages and disadvantages when used as a source of information in case of crime.
Identical twins: There are some common fragments of DNA that is same in identical twins so it can be a difficulty in deciding the criminal.
Not enough of a sample: DNA should be present in a detectable amount to be used an sample for evidence, less than this detectable amount is a waste and cannot be used as a sample for evidence.
Contaminated and degraded sample: If the sample of DNA is contaminated or degraded then the result might be incorrect and might not be used as a sample for forensic evidence.
Hence, the correct answers are all of the above.
The ability of the brain to acquire information, feelings, and processed, keep, and recollect this for the subject is called memory.
The threes stages of memory are
The ability of Roger to keep memory of the names with these three stages, depends on how pays attention and his ability to process information.
The sensory storage depends on the five sense to send information to his brain. Thus, Roger needs to pay attention to the faces,(iconic memory) voices (echoic memory), feel or touch (Haptic Memory) and (Smell) aroma of perfumes when been introduced to the guest.
These information are retains for few seconds after the guest( the sensation has gone).Thus with this ,he sees every guest as collective set of people without and not as individual. For his brain to process the information as individual he needs to network with the Short memory.
The short memory is the type that retain the information( the names ,voices and touches) of the guests he was introduced to at that present moment. He needs to pay attention and try to retain these sensation to prevent them from been forgotten. These sensations are retain tentatively until the information is processed. It is these processed information that are stored by his brain ,and not the sensory signals like in the sensory.
In order for the processed or interpreted information to be stored and used for longer time, and recalled when needed, these are transferred to the long term memory. This is subdivided into two types; explicit and implicit memory.
He will makes use of the explicit memory because the stored names can be recollected consciously after storage when the 3 types of memories are merged. Unlike the implicit that can not be access consciously.
With the capture of the image of the guest with sensory memory, temporary store the processed names with short term and stored this for future, Roger should be able to remember these names.
Answer:
In this situation, the role of sensory storage would be-
as he enters at reception the smalls, images, would be sensed by him and make its burn the memories in his brain.
Short-Term memory helps in make him remember by the names associated with the small gesture, movement, mannerisms made by them. For example, sam stutters can be remembered as stutter Sam.
Long-Term memory helps in building memory by long haul with help of scenery by relating individuals he already know before the reception and whenever see them mind reminds the name.
Answer:
Explaining Below V
Explanation:
There are 5 different kinds of climates globally.
Tropical
Dry
Temperate
Continental
Polar
Tropical climates are very hot and humid. There's lots of rain (estimated around 59-60 inches per year). The average temperature tends to be over 60°F or 18°C. Plants you can find are incredibly diverse in both plants and animals. You can find animals such as monkeys, parrots, anacondas, jaguars, tigers, and many more. The tropics have the greatest plant diversity on the planet. The climate generally is centered around the equator.
Dry climates are generally very warm and dry. Humidity is very unlikely as everything is mostly dry heat. There's very little precipitation. Dry climates usually consist of deserts (Fe: Sahara desert). Plants such as cacti, succulents, wildflowers, and small trees, shrubs, and grasses. Animals can vary from things such as tarantulas, rattlesnakes, foxes (only some), camels, and rabbits. Depending on the desert, the heat can shoot up past 100°F while being frigid at night.
Temperate climates are generally warm summers with storms and mild winters. Plants can range from owls, raccoons, sparrows, meadowlarks, deer, and occasionally bears. This climate fluctuates the most in temperature compared to other climates. Plants can range from things like clover plants to a common bean.
Continental climates have mediocre summers with very cold winters. In the winter, snowstorms and strong winds are most likely. Sometimes, the temperature can drop below -22°F. Plants can range from Lavender and fern to Carolina Lupine and Silver maples. Animals can consist of squirrels, chipmunks, prairie dogs, skunks, and raccoons.
Polar climates are frigid. Its cold year round. There's animals such as polar bears, foxes, wolves, and caribou. Plants can vary from Tundra moss to Arctic Willow. Plants are generally smaller and are more like tiny shrubs.
Hope this helps.
b. myofilament
c. sarcolemma
d. endomysium
Answer:
Sarcomere
Explanation:
Myofibril is the unit of the muscle cell. The myofibril is rod like in structure and developed by the process of myogenesis in embryo.
Sarcomere is the basic structural unit of the skeletal muscles and shows striations under the microscope. Sarcomere consists of thick and thin filaments of actin and myosin. Different bands like A- band , H-Band, I-Band and Z- line is visible in the sarcomere.
Thus, the correct answer is option (A).
It is risky to build something whose natural frequency is matched with external vibrations because of ; The effect of resonance
When an object constructed has a natural frequency which is equal to the frequency of a nearby external vibration, the amplitude of the vibration of the object will increase due to the resonance effect which occurs because the external frequency matches up with the natural frequency of the constructed object.
The negative effect of resonance is the increase in the amplitude of the vibration of the object which might lead to the partial or complete collapse of the constructed object.
Hence we can conclude that It is risky to build something whose naturalfrequency is matched with external vibrations because of ; The effect of resonance

Answer:Most objects have at least one natural frequency of vibration. If a nearby object vibrates at the same frequency, it can cause resonance. Resonance is an increase in amplitude of a vibration that occurs when external vibrations match an object's natural frequency.
Explanation:
B. a hemisphere
C. a pressure gradient
D. an air mass
Answer:
D. an air mass
Explanation:
Answer:
An Inherited behavior is a behavior received from the parents through genetics such as long legs for speed while a learned behavior is a behavior in wich an animal has to learn by itself by looking at past experiences such as baby ducks learning how there mother duck avoids danger.
Explanation:
Answer:
A learned behavior is more a behavior that is learned from experience of an organism. An example is imprinting, in which a young animal comes to recognize (another animal, person, or thing) as a parent or other object of habitual trust.
An inherited behavior is one that is innate, something that is bestowed upon an organism at birth. An example is animals starting to instinctually prepare for winter as the weather turns cold during the fall.
