Experiments have shown that adult human hearing is most sensitive in the frequency range of the sound of a human baby crying. Based on the threshold of audibility curve shown for an adult male shown below, into which frequency range does most babies' crying fall? Threshold of audibility equal-loudness curve A. 25 – 50 Hz B. 250 – 500 Hz C. 2500 – 5000 Hz D. 10,000 – 20,000 Hz
Answer:
The correct answer is - C. 2500 - 5000 Hz
Explanation:
According to the graph, there is the threshold of audibility curve that exhibits that at 2500 Hz and 5000 Hz, the lowest thresholds of audibility are present. So the sound that is faintest can be heard at 2500 Hz and 5000 Hz.
This is the reason that te humans are sensitive to the crying of the babies as they must cry at 2500 Hz and 5000 Hz frequency and we get their attention easily.

In your own words, describe how the time required for digestion can be used to determine the time of death.
Answer: Backdating the time required for food found in the stomach of the deceased to digest. Since digestion can't continue after death.
Explanation: The time taken for food to get digested can be employed to depicts time of death. This process involves understanding the period of time that usually takes the food found in the gastric of the deceased to calculate the time of death.
Different foods has varying time of digestion, so therefore, the gastric content is a good indicator to determine time of death by the doctor who is carrying out autopsy, since digestion does not continue after death.
However, it is established by scientist that food takes up to 4-6hours in the stomach depending on the size and type of food. Hence, if the status of the food found in the deceased stomach is noted accordingly and the time taken requires for digestion is also noted، the doctor can deduce the time of death accordingly from this two points.
The air outside is so warm that this snowman is melting. During melting, the water molecules (gain/lose) thermal energy. How does the motion of the molecules change during melting?
Answer:
they gain thermal energy because they are warming up. the molecules are speeding up because liquid molecules are faster the solid molecules which don't move much.

Which of the following could be a function of a phagocyte?
Choose 1 answer:
A. Acting as a physical barrier against pathogens
B. Activating B cells
C. Engulfing a foreign pathogen
D. Making antibodies specific to a pathogen
D. Producir anticuerpos específicos para un patógeno
The following could be a function of a phagocyte, Making antibodies specific to a pathogen.
What is chemotaxis?
The process of attracting the phagocytes to the site of injury is known as chemotaxis.
The chemotaxis is a part of the inflammatory response of the body. The phagocytes once attracted to the site of the injury ingests the bacteria by attaching to the bacterial cell wall.
The ingestion of the invading bacteria is known as phagocytosis. The destroyed bacteria is then released from the phagocytes.
Thus, option D is correct, Making antibodies specific to a pathogen.

If yellow skin (Y) exhibits incomplete dominance with red skin (y), what color of skin would result from the genotype Yy?
Answer:
Orange skin
Explanation:
Incomplete dominance with the genotype Yy results in a combination of the dominant and recessive traits. In this case the combination of yellow and red skin would be orange skin.
On the African savanna, grasses feed wildebeest, gazelles, and hares. Lions, hyenas, and cheetahs hunt the wildebeest and gazelles. Vultures eat the remains from predator kills. Bacteria and fungi break down anything that is left over from the carcasses. Dung beetles eat the feces left behind from grass-eating animals like hares and elephants.

How might predict whether one of the siblings will have children that show the trait of albinism?
Answer: — Girls with albinism usually have OCA not OA and should be tested for the OCA genes. Boys can have OA or OCA. Sometimes doctors cannot tell if a child's hair and skin is affected by albinism just by looking at a child. Genetic testing may be able to tell which type of albinism your child has.
Explanation:
Albinism is usually passed either from one unaffected parent (OA) to a child or from both unaffected parents (OCA) to a child. A parent who is not affected with albinism but has the gene mutation that causes it is called a "carrier".
Seismographs rely heavily on a pendulum (free-swinging weight) to record measurements. How do you think using a pendulum helps detect small earthquakes?
Answer:
Generally, a seismograph consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage. The electrical voltage is recorded on paper, magnetic tape, or another recording medium.
Principle of a pendulum: a heavy, inert mass with a certain resistance to movement (i.e. inertia) due to its weight is suspended from a frame by a spring that allows movement. The energy from any seismic activity excites this “proof mass” as it is called by geophysicists, making it vibrate. When they detect movement, such as the shifting plates of an earthquake, a pendulum with a pen attached to it graphs the magnitude of the movement. If the pendulum swings vigorously, scientists know that the seismic waves are intense and potentially dangerous. My guess is, when pendulum swings lightly it determines mild intensity and small impact of an earthquake.
how do animals contribute to the carbon cycle
Answer:
hope it helps have a nice day
Answer: All animals, from humans to the dinosaurs are part of the carbon cycle. When animals eat food, they get carbon in the form of carbohydrates and proteins. The carbon combines with oxygen to form carbon dioxide [CO2] and is released back into the atmosphere as a waste product when animals breathe and exhale.

What is the greenhouse effect? How does it occur and why is it important? ps i didnt know what subject it was
Answer: The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth's temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist. Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space. This heat trapping is known as the greenhouse effect. Just as too little greenhouse gas makes Earth too cold, too much greenhouse gas makes Earth too warm.
