Explanation:
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.

Hope this helps!
Answer:
The breast
Explanation:
The breasts are organs of the female body that contains milk ducts, adipose tissue, and mammary glands. The two breasts are located on the left and right sides of the thoracic region or upper ventral region of the body. In the middle or hub of each breast is a nipple, which is highly pigmented and releases milk when stimulated.

A small group of birds became isolated from a large population when deforestation occurred for the development of new buildings. Over the course of a few generations, the gene pool of the small group became drastically different from the original population. Which of the following best describes this occurrence?
A selective process caused an increase in the population's genetic variation.
The founder effect caused the chance event that altered the allele frequency.
Bottleneck effect led to over-representation of certain alleles in the new gene pool.
Gene flow led to an increase in the gene pool's allele frequencies.
I'm thinking it's the founder effect, which according to something I found on the Internet is genetic variation from when a population originates from a small amount of species.
Bottleneck effect led to over-representation of certain alleles in the new gene pool. Therefore, option (C) is correct.
The phenomenon known as the bottleneck effect takes place when a population suffers a significant decrease in size, which leads to a reduction in the amount of genetic variation in the population. In this hypothetical situation, the clearing of land for new construction and the introduction of new structures led to a small group of birds becoming cut off from the larger, original population of birds.
Due to the fact that this small group was kept apart from the larger population, a phenomenon known as a bottleneck effect occurred. This caused the gene pool to become strikingly dissimilar to that of the original population as a result of the overrepresentation of certain alleles in the new gene pool. As a result, the response that should be chosen is option C.

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.

b. a liquid, such as oil
c. a permeable material, such as gravel
d. a material that does not have pores
Answer:
I would say A
Explanation:
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.

Compare the practices of shelterwood cutting, clearcutting, and seed-tree cutting.
Answer:
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:
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.

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:
