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.
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.
On your first research mission you make an amazing discovery by finding a new species living in the hostile environment of the Sahara desert. After observing it carefully you determine that it is not an autotroph, it is multicellular, and it does not contain any chitin. What is the best classification for it
Answer:
Animalia
Explanation:
A multicellular organism is an organism composed of two or more cells. Multicellular organisms include animals (i.e., organisms from kingdom Animalia), plants, and most fungi. Moreover, an autotroph is a living organism that can produce its own food by using materials from inorganic sources (e.g., water, carbon dioxide, etc); whereas a heterotroph is an organism that cannot produce its own food and thereby needs to eat other organisms, like plants or animals, to survive. Multicellular autotrophs are typically plants; whereas multicellular heterotrophs include all animals, fungi and some parasitic plants. Finally, chitin is a polysaccharide (polymer) of N-acetylglucosamine, which is found in the cell wall of fungi, as well as in the exoskeleton of some animal groups such as, for example, insects, crustaceans, etc.

Name five types of evidence that support the theory of evolution. Write one sentence for each, explaining why it demonstrates evidence. (10 points)
The five evidences that support the theory of evolution are: Fossils, Anatomy, Embryology, Molecular Biology (or Biochemistry), and Biogeography.
Fossils show the physical change in a species over time, suggesting evidence for evolution. For an example, we can trace the origins of dolphins and whales all the way to a four-legged, dog-like hoofed mammal from about 50 mya. These mammals were fish eaters and so decided to spend a lot of time in the water. In fact, they spent so much time in the water, that in a few million years, they evolved a longer body and webbed feet. Then another few million years passed and they swapped their webbed feet for flippers and swapped their tail of a fin. Eventually, we get a fish-like mammal that once walked on land.
For anatomy, or structures, there's three types of structure comparisons: Homologous structures, Vestigial structures, and Analogous structures (or Convergent Evolution). Homologous structures show similarities between the structures between species, but serve different purposes. For an example, all mammals share common features within their arms, such as having 5 fingers. However, they serve different purposes, from whale fins for swimming, to bat wings for flying, to human hands for grabbing and for using tools.
Vestigial structures were structures that once served a purpose and have been reduced in size/power to the point where it's useless. For an example, large theropods such as the T. Rex spent so much time evolving more jaw muscles and biting power, that they sacrificed their arm muscles for such power. This explains why their arms were so short.
Another example would be ratites, flightless birds such as ostriches, emus, and cassowaries (penguins and kakapos are from a different group). They spent so much time evolving powerful legs as well as evolving in size, that there was no need to fly when they could just run with their improved legs. And also the fact that they're too heavy to even fly anyways.
Analogous structures is the similar functions of structures between species, but have separately evolved these functions. For an example, the wings from insects, birds, bats, and pterosaurs are very similar in shape and can be used to fly, but they've evolved separately. For an example, birds use feathers to fly while bats and pterosaurs use/used (pterosaurs are extinct) membrane between their bones to fly. Although they do have strikingly similar evolutionary histories, with their ancestors starting off as tree dwellers, they've evolved their flight abilities separately during different earth periods.
Embryology is evidence for evolution by using embryos from different species to suggest a common ancestor. For an example, we can prove that we're more related to whales than to fish by using embryos. The fish embryo will evolve gills while the embryos of humans and whales will not, since we do not breath by extracting oxygen from water.
Molecular biology is a more recent way of providing evidence for evolution. By taking the DNA from cells from different species, we can get an estimate of how related one species is to another. The more similar amino acid sequences are between species, the more recent their common ancestor is. For an example, by comparing amino acid sequences between humans and chimpanzees, we get an estimated amount that we once shared a common ancestor seven million years ago. Without molecular biology, we would still be digging for fossils to find that number.
Biogeography is the geographic distribution of species on earth that can be explained by evolution. For an example, we can tell that Australia separated first from Pangea rather than Asia or North America since Australia doesn't have bears while the Asia and North America do, with China having pandas and North America having brown and black bears. And also with the fact that Australia is the only continent with monotremes (egg-laying mammals like the platypus).
Similar to biogeography, there's also direct observation, which is evolution that has happened in our own eyes. An example would be the underground London mosquito. Mosquitoes usually target birds like pigeons. But after an underground tunnel was built in London, some mosquitoes managed to get inside and instead of birds, they targeted, mice, rats, and of course, humans. After only a few hundred years, a mosquito from the underground tried to mate with another mosquito from land and they could not, simply because they were different species. This shows that their new choice of feeding on mammalian blood has actually altered their DNA and created a new species, during the existence of humanity!

The movement of oxygen from the alveoli into pulmonary capillaries and carbon dioxide from pulmonary capillaries to the alveoli is: Select one: a. Internal Respiration b. External Respiration c. Pulmonary Respiration d. None of the above.
Answer:
External Respiration.
Explanation:
External Respiration is the type of respiration in which exchanges of gases occurs between the lungs and the bloodstream i.e. pulmonary capillaries. Inside the lungs, oxygen is loaded into the hemoglobin and carbon dioxide waste is unloaded, this process is called external respiration. This respiratory process takes place through the help of hundreds of millions of microscopic alveoli.

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.

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.

Why there is a variation of weather in two different parts of India, though climate
was summer?
Answer:
Due to distance from the equator.
Explanation:
There is a variation of weather in two different parts of India, though climate was summer because both parts experience different amount of sunlight. There are some regions in India which is located on the equator so they experience very hot weather while on the other hand, some regions are present at a large distance from the equator so direct sunlight does not occur and the temperature is moderately warm.
