One day you were suddenly awakened by a ghostly shriek as if it were coming from
beneath your bed. Then a shadow seemed to advance towards you. You felt choked and
lost your consciousness. When you regained to your senses you were on your bed,
puzzled but safe. Describe your experience in the form of a short story in about 200–250
words.
(Use only the past tenses, title the story and have a moral at the end)
Answer:
THE NIGHTMARE
I woke up with a start, sweating profusely, my heart pounding erratically against my chest. My hands were shaking uncontrollably and I held my pillow close to my chest to clam my nerves. I had heard it. There was no doubt in it. A loud, high-pitched shriek, which sounded nothing like a human cry. It was surreal, making a shiver to creep up my spine. I twisted my hands together in nervousness, and murmured a prayer to god. The ghostly sound had resonated from beneath my bed. I had read way too many horror stories to not be scared by now. My throat felt dry and parched and I longed for a sip of water. But I had to go downstairs to fetch the jug. That meant I had to get down from my bed. And there was no way I would do that. Not now, when I was literally scared to death. I swallowed hard. My breathing had slowed down a bit but my heartbeat was still erratic. I perked up my ears and waited to see if the shrieks continued. I badly wanted to cover myself with my blanket but I was too scared to move an inch. I waited for about a minute and could hear no sound. This eased me a bit. Just when I mustered the courage to lie back down and go back to sleep, I felt a shadow whisk past me, sending the curtains flying. I brought my hands to my mouth to stop myself from crying out in terror. It was the silhouette of a girl, a tall, slender figure that I was sure by now was somewhere around me. I felt my eyes brimming with tears but I held my cries back. It was when the shadow reappeared, this time closer to me, near my nightstand. And before I could register what was happening or cry out loud for help, the figure advanced towards me, and all of a sudden, held me in a death grip. I felt myself being choked so tightly that no sound was escaping my mouth, black dots swimming in my vision. Soon enough, I plunged into darkness. After what felt like hours, I opened my eyes to be greeted with the golden rays of the sun streaming in through the window near my bed. I had a slightly blurry memory of yesterday night. I felt around my surroundings, and was met by relief when I could feel the blankets and my pillow beside me. Overjoyed by the fact that I was safe, and that it all had been just a silly nightmare, I thanked God and got out of bed to start my day.

There is evidence that the Bertillon System was used in ancient Egypt, India, and
China.
The Bertillon System was used in the United States and Europe before fingerprinting
replaced it
The Bertillon System is no longer used today by law enforcement
In the Bertillon System, sets of measurements were taken of each criminal, and
thought to be unique
Answer:
The statement that is false would be the third answer.
Explanation:
Sorry if this is wrong. I was doing my best.
Answer:
Option third is false.
Explanation:
Alphonse Bertillon in the later 18th century developed a system of solving crimes through a standardized process of bodily measurements, photographs, footprints, impressions, and thumbprints which created a unique identification of every criminal. The system gained popularity and acceptance in no time and various countries around the world accepted it as a part of law enforcement. Earlier, law enforcement was largely dependent on the Bertillon system to establish identity but with the advancement of science and introduction of fingerprinting this system was replaced by fingerprinting.Although, some of the methods of the Bertillon system are still part of the forensic methods of solving crimes while anthropometry was discarded.For more information:

Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years. Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area.
What happens in the process of clearcutting?Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years.
Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area. Seed-tree cutting and shelterwood cutting allow for the harvested areas to recover over time without direct intervention.
The scale of clear-cuts throughout Oregon is limited by law, although proprietors have been required to leave trees throughout specified locations to preserve waterways as well as provide wildlife habitats.
Therefore, Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years. Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area.

Explanation:
Name one way that each of the three food
production systems (crops, meat, and fish/shellfish) can result
in environmental problems.
Answer:
Crops: Contamination by uncontrolled use of chemicals such as pesticides and fertilizers. Deforestation.
Meat: Water pollution with animal wastes, chemicals, and other toxic and contaminants. Deforestation.
Fish: Overfish and accessory capture.
Explanation:
Crops: Industrial farms make unconscious use of pesticides and fertilizers that penetrate the soil contaminating it, polluting water, and affecting plants and animals that live around that land and beyond. Animals and people exposed to pesticides such as insecticides, fungicides, and herbicides, have been shown affected by their effect.
Meat: Meat production turns to be one of the principal causes of water and soil pollution. Contaminants originate mostly from animal wastes (dung, blood), antibiotics, hormones, chemical substances used in the tannery, and sediments of eroded soils.
Both industries play a principal role in global deforestation. Most native forests get cut down to make a place for the development of these activities.
Fish: Overfish is one of the most important environmental problems caused by fisheries. Uncontrolled resource overexploitation leads to species´ extinction. Huge amounts of animals get caught in any of their stages of development. Young animals do not reach the reproductive stage, and reproductive females can not release eggs. This causes important damage to the reproductive rate of the species. Also, when overexploiting, many other unwanted species get caught and die on the nets. Accessory capture is the cause of death of many invertebrates, fishes, and marine mammals die because of the fisheries nets.
The three food items like crops, meat, and fish can lead to environmental problems by the release of GHG, overconsumption, and land degradation.
What aspect of the food items of the production system harm the environment. ?The food production system like the crops can lead to an increase of gases and removal of forest lands that leads to less habitat for wildlife. The production of meat either sheep, cow, buffalo, etc. will lead to the release of the GHG and increased resource depletion.
Overfishing will lead to the tragedy of commons and similar these aspects will lead to land degradation by excessive utilization of resources. Hence impacting the environment.

4. Species interact with each other in their environments. Describe the relationship between the two species of
barnacles and the snail species. Use the words: symbiosis, predation, competition, fundamental niche, realized
niche.
|
Answer:
Predation is the relationship.
Explanation:
Predation is the relationship present between the two species of barnacles and the snail because snails feed on barnacles for their living. In the fundamental niche, the snail grow in population due to availability of suitable environmental conditions, but when there is realized niche, predation and competition exists which limits the growth of the population of organism. Here barnacles population is limited due to presence of snail which feeds on it.

Jane had two wind up clocks that had not been used for years. She decided to try them out, so she wound both, set the time, and started them at the same time. An hour later, clock A had gained one minute while clock B had lost two. The next morning clock A said 7 A.M. while clock B was at 6 A.M. What time was it when she started the clocks?
Right now, the clocks are one hour apart. The clocks are 3 minutes apart every hour. It would take 19 hours and 20 minutes to get from 6 A.M. to 10:40 A.M.
How to find a time?Right now, the clocks are one hour apart.
The clocks are 3 minutes apart every hour (A gains 1 - B loses 2)
Therefore, it would take 20 real hours for them to be separated by one hour.
Clock A advances by one minute per hour, moving 20 hours and 20 minutes throughout that time.
It would be 10:40 a.m. from 7 a.m. back 20 hours and 20 minutes.
Clock B advances by 2 minutes every hour, or 19 hours and 20 minutes, in a period of 20 hours.
It would take 19 hours and 20 minutes to get from 6 A.M. to 10:40 A.M.

Select the statement(s) that support bird beak adaptations as
supporting evidence for the theory of natural selection.
-The top bird with a beak adapted for
insect eating would not succeed on a
Galapagos Island with little insects but
plentiful seeds.
-The middle bird with a woodpecker
beak adapted for seed eating most
likely could dig deeper for larger,
harder covered insects more
successfully than the top bird with the
insect eating beak.
The bottom right bird with a beak
adapted for seed eating would succeed
on a Galapagos Island with plentiful
insects but little vegetation.
The bottom right bird with a beak
adapted for seed eating would succeed
on a Galapagos Island with plentiful
vegetation and few insects.
Answer:
-The top bird with a beak adapted for insect eating would not succeed on a Galapagos Island with little insects but plentiful seeds.
-The middle bird with a woodpecker beak adapted for seed eating most likely could dig deeper for larger, harder covered insects more successfully than the top bird with the insect eating beak.
-The bottom right bird with a beak adapted for seed eating would succeed on a Galapagos Island with plentiful vegetation and few insects.
Explanation:
The theory of natural selection explains that organisms undergo changes in their physical and genetic features that make it possible for them to adjust to their environments. There are different types of birds having different shapes of beaks adapted for life in several environments.
There are insectivorous birds whose beaks are adapted for eating insects, granivorous birds with short, conical beaks for cracking seeds, frugivorous birds adapted for eating fruits, nectivorous for sucking nectars, among others. The adaptations are unique to the birds and determine their survival and feeding habits in several environments.
