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.

Seismographs rely heavily on a pendulum (free-swinging weight) to record measurements. How do you think using a pendulum helps detect small earthquakes?

Answers

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.

In your own words, describe how the time required for digestion can be used to determine the time of death.

Answers

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.

What is the greenhouse effect? How does it occur and why is it important? ps i didnt know what subject it was

Answers

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.

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

Answers

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.

How might predict whether one of the siblings will have children that show the trait of albinism?

Answers

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".

All my life I had been looking for something, and everywhere I turned someone tried to tell me what it was. I accepted their answers too, though they were often in contradiction and even self-contradictory. I was naive. I was looking for myself and asking everyone except myself questions which I, and only I, could answer. It took me a long time and much painful boomeranging of my expectations to achieve a realization everyone else appears to have been born with: That I am nobody but myself. But first I had to discover that I am an invisible man!And yet I am no freak of nature, nor of history. I was in the cards, other things having been equal (or unequal) eighty-five years ago. I am not ashamed of my grandparents for having been slaves. I am only ashamed of myself for having at one time been ashamed. About eighty-five years ago they were told that they were free, united with others of our country in everything pertaining to the common good, and, in everything social, separate like the fingers of the hand. And they believed it. They exulted in it. They stayed in their place, worked hard, and brought up my father to do the same. But my grandfather is the one. He was an odd old guy, my grandfather, and I am told I take after him. It was he who caused the trouble. On his deathbed he called my father to him and said, "Son, after I'm gone I want you to keep up the good fight. I never told you, but our life is a war and I have been a traitor all my born days, a spy in the enemy's country ever since I give up my gun back in the Reconstruction. Live with your head in the lion's mouth. I want you to overcome 'em with yeses, undermine 'em with grins, agree 'em to death and destruction, let 'em swoller you till they vomit or bust wide open." They thought the old man had gone out of his mind. He had been the meekest of men. The younger children were rushed from the room, the shades drawn and the flame of the lamp turned so low that it sputtered on the wick like the old man's breathing. "Learn it to the younguns," he whispered fiercely; then he died.But my folks were more alarmed over his last words than over his dying. It was as though he had not died at all, his words caused so much anxiety. I was warned emphatically to forget what he had said and, indeed, this is the first time it has been mentioned outside the family circle. It had a tremendous effect upon me, however. I could never be sure of what he meant. Grandfather had been a quiet old man who never made any trouble, yet on his deathbed he had called himself a traitor and a spy, and he had spoken of his meekness as a dangerous activity. It became a constant puzzle which lay unanswered in the back of my mind. And whenever things went well for me I remembered my grandfather and felt guilty and uncomfortable. It was as though I was carrying out his advice in spite of myself. And to make it worse, everyone loved me for it. I was praised by the most lily-white men of the town. I was considered an example of desirable conductjust as my grandfather had been. And what puzzled me was that the old man had defined it as treachery. When I was praised for my conduct I felt a guilt that in some way I was doing something that was really against the wishes of the white folks, that if they had understood they would have desired me to act just the opposite, that I should have been sulky and mean, and that that really would have been what they wanted, even though they were fooled and thought they wanted me to act as I did. It made me afraid that some day they would look upon me as a traitor and I would be lost. Still I was more afraid to act any other way because they didn't like that at all.
