Give the functions of the following parts of the respiratory system - Nostril - trachea - bronchiole - alveoli - pharynx - larynx - lungs - ribs - diaphragm
Answer:
Respiratory System: The respiratory system's main job is to move fresh air into your body while removing waste gases.
Nostril: To warm air on inhalation and remove moisture on exhalation.
trachea: Serves as passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles.
bronchiole: To deliver air to a diffuse network of around 300 million alveoli in the lungs.
alveoli: To exchange oxygen and carbon dioxide molecules to and from the bloodstream during breathing.
pharynx: Helps the respiratory system by allowing air to make its way to the respiratory tract.
larynx: Produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.
lungs: To help oxygen from the air we breathe enter the red cells in the blood.
ribs: To aid respiration and help protect the lungs.
diaphragm: Contracts and flattens when you inhale. Creates a vacuum effect that pulls air into the lungs, and relaxes when exhaling.

In many parts of the world, the average age of reproductive maturity is increasing as humans move from urban to rural environments. Suppose that the current average age of first reproduction is 15 years old in India and 20 years old in France. How would a 5-year increase in the average age of reproduction in both countries be expected to affect the per capita birth rate, and would this effect be greater in France or in India
Answer:
Increase in France.
Explanation:
A 5-year increase in the average age of reproduction in both countries i.e. France and India, it will greatly affected the per capita birth rate of both countries but higher in France because the average age of reproduction is higher in France as compared to India. The average age of first reproduction is 15 years old in India and 20 years old in France but with the increase of 5 years, the average age of first reproduction is 20 years old in India and 25 years old in France.

Your service club is offering a prize for the best community educational plan. Not only would you love to win the prize, but you think this is a good opportunity to advocate against ATOD abuse. You know that ATOD abuse can be a big problem in a community, and you want to help people learn about it.
Before you start creating your campaign, it's important to research what is going on with ATOD abuse in your community.
1. Using local news media sources, find five news stories related to ATOD abuse in your community. For each news story, identify a barrier that prevented the person or people involved from making better decisions regarding ATOD use.
1. Hailey Hesch started using dr#gs when she was 12 years old. She experimented with a lot of hardcore dr#gs like h3roin. A barrier that prevented her from stopping her addiction to the feeling she got when she took dr#gs. She said it made her feel amazing and really happy.
2. Jeremy B smoked a lot of w33d, drank, fought people, and chased girls around with his friends frequently. After a while, he started to use and experiment with other dr#gs like h3roin and d0pe. A barrier that prevented him from making healthier choices was due to curiosity.
3. Kristina started her dr#g addiction with painkillers she took for an injury. She took them as they were prescribed at first, but after losing an opportunity to get a scholarship, she started abusing the painkillers. However, the painkillers were not enough, so she started using hardcore dr#gs to try to reach a "High". Nothing worked so then she kept abusing them more and more. She noticed that she was becoming very unstable, so she forced herself to get treatment. A barrier that prevented her from making better decisions was because she was blinded by grief and anger.
4. Adam was a 27 year old who was very athletic and smart. No one would have seen it coming, but he died due to a dr#g overdose. There was no one in his entire family that knew about his addiction, and when they found out, it was too late. A barrier that made him addicted is unknown, but some people suspect that it was because of friends or outside influences.
5. Cassie was a smart and successful woman who was very well-rounded. She went to church, donated to charities, and helped children with activities like tutoring and basketball. However, her parents started noticing unusual behavior from her. She shut herself off, had intense mood swings, and looked physically exhaused. Their suspicions were confirmed when she collapsed in the middle of the day. The doctor's diagnosis stated that she overdosed on m3th and that she was in a permanent coma. Later, the doctor broke the awful news to her parents, Cassie had irreversible brain damage and was a lost cause, so she died after being taken off of life support. A barrier that prevented her from making better choices was that no one took action when her behaviour drastically changed.
What is the correct order of structures in a chromosome from smallest to largest? nucleosome, nucleotide, histone, tight helical fiber, supercoil, chromosome nucleotide, histone, nucleosome, tight helical fiber, supercoil, chromosome nucleotide, nucleosome, histone, supercoil, tight helical fiber, chromosome nucleotide, histone, tight helical fiber, nucleosome, chromosome, supercoil
Answer:
nucleotide, histone, nucleosome, tight helical fiber, supercoil, chromosome.
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
The complex structures of deoxyribonucleic acid (DNA) and protein found in the cell nucleus are generally referred to as chromosomes.
Chromosomes are found in the cell nucleus and are comprised of deoxyribonucleic acid (DNA), histone proteins, etc. Thus, they are used to store genetic informations in living organisms.
The human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
In Genetics, the correct order of structures in a chromosome from smallest to largest are; nucleotide, histone, nucleosome, tight helical fiber, supercoil, chromosome.

The word kinetic comes from the Greek word Kinetikos, which means motion.
1) GPE = 100 J
mgh = 100
Therefore, height above the ground,
h = 100/mg = 100/(2 x 9.8)
h = 5.1 m
2) The word kinetic comes from the Greek word Kinetikos, which means motion.
3) Displacement is the measure between the difference in start and end positions.
4) Satellite is an object called that orbits another object.
5) v = s/t
v = 10/1v = 10 m/s
6) According to Newton's second law, F ∝ a. So, when the car's acceleration triples, the force on the car also triples.
7) Kinetic energy, KE = 1/2mv²
KE = 1/2 x 2 x 6²
KE = 36 J

Explanation:
The role of the fungus in the food web shown is to recycle molecular building blocks. The correct option is A.
What is food web?A food web is a diagram that depicts the interconnection of various organisms in an ecosystem via the exchange of energy and nutrients.
The food web is made up of several interconnected food chains that represent the flow of energy from one organism to the next.
Fungi are decomposers that play an important role in breaking down organic matter and recycling nutrients in many ecosystems.
The fungus in the food web is most likely breaking down dead plant or animal matter, releasing nutrients like carbon, nitrogen, and phosphorus back into the soil.
These nutrients are then absorbed by plants, which are then consumed by herbivores such as the coati and sloth.
Thus, the correct option is A.

A scientist lives near a wind farm and is wondering about the environmental effects of the wind turbines. They ________ that the turbines make a sound like faint airplane engines and also that there are far fewer meadowlarks living near the windfarm than lived there were before the windfarm was built.
Answer:
Due to sound, population is decrease.
Explanation:
Due to noise of the wind turbine, there is decrease in population of meadowlarks in that region which is the only adverse effect of wind turbine. This wind turbine produces clean energy and produces no pollution like energy produce from burning of coal. This migration of meadowlarks can imbalance the ecosystem that has a great effect on the surrounding area.
The La Brea Tar Pits in Los Angeles are the site of millions of fossils from the ice age. Woolly mammoths, giant sloths, dragonflies, and other plants and animals from this era have been found in these pits. Scientists at the tar pits discovered that many of the smaller animals they extracted from the pits still exist around Los Angeles today. But many of the larger mammals—such as woolly mammoths and saber-toothed tigers—are now extinct. Why do you think this is the case? What can scientists learn about Los Angeles' climate history by studying the specimens found in these tar pits?
Answer:
Scientists learn how climatic changes during the ice age affected life in this region by analyzing specimens found in these tar pits
Explanation:
La Brea Tar Pits are a group of tar pits in Los Angeles. Many preserved remains of ancient organisms (i.e., fossils) were extracted from the tar, including, among others, Western horses, prehistoric camels, three-toed tapirs, rodent bones, insects, mollusks, wood, plants, etc. The oldest fossils have been dated to be approximately 38,000 years ago by radiometric techniques. Moreover, the Last Glacial Period was the most recent glacial period within the Quaternary glaciation, which encompassed the period between 115,000 to 10,000 years ago. This period (LGP) encompassed the Last Glacial Maximum (LGM), which occurred about 20,000 years ago. In consequence, many of the fossils found in La Brea Tar Pits evidence how the ice age affected life in this region. Moreover, many of the fossil species extracted from the tar are still present today, thereby indicating how these species adapted to fluctuating climatic conditions, whereas certain species couldn't adapt fast enough as the environment changed and therefore they went extinct.
Answer:
Scientists at the tar pits discovered that many of the smaller animals they extracted from the pits still exist around Los Angeles today. But many of the larger mammals—such as woolly mammoths and saber-toothed tigers—are now extinct. I believe this is the case because since bigger beasts couldn't take shelter in small protected burrows, perhaps they were done in by fierce environmental conditions. Or maybe with so many plants dying off, big herbivores simply had nothing to eat, and as they died out, so did the big carnivores. By studying the spicemens found in these tar pits scientists can learn about Los Angeles climate change. For instance, new scientific studies at the La Brea Tar Pits are probing the link between climate warming and the evolution of Ice Age predators, attempting to predict how animals will respond to climate change today.
