Answer:
deoxyribose
Explanation:
A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.

Which approach would be least helpful in determining genetic differences between species?
Answer:
the least helpful would be a straight up guess, the best way would be to to back in the history of that species and study how they lived and survived and reproduced and all that stuff
Explanation:
Comparing physical characteristics between species is not a reliable method for determining genetic differences because many physical traits are influenced by environmental factors and may not necessarily reflect the underlying genetic differences between species.
What is an example of this ?For example, two species may have different fur colors or patterns, but this difference may be due to environmental factors such as exposure to different types of light rather than genetic differences.
In contrast, analyzing DNA sequences can provide a more precise and objective way to identify genetic differences between species. By comparing the DNA sequences of different species, scientists can identify variations in genes and regulatory regions that may be responsible for differences in traits or behaviors between species.
This approach can also reveal the evolutionary relationships between species and provide insights into how genetic variation has driven the diversification of life on Earth.
Therefore, Advances in genomic technologies have made it increasingly feasible to sequence and compare the genomes of diverse species. Comparative genomics has already revealed many insights into the genetic basis of traits such as human disease susceptibility, adaptation to environmental challenges, and the evolution of complex traits such as intelligence and social behavior.

The inflammatory response is an innate reaction to invasion by a pathogen regardless of whether that pathogen had been previously encountered. Which statement best describes the symptoms of redness and swelling at the site of a splinter after its removal? A) Interactions of the circulatory and immune systems create an increased blood flow and immune cell metabolism, which causes redness and swelling. B) Interactions of the respiratory and immune systems create an increased breathing rate and immune cell metabolism, which can lead to redness and swelling. C) Interactions between the immune system and digestive system increase the digestive enzyme activity at the site of the infection, which leads to redness and swelling. D) Interactions of the immune system and nervous system lead to increased cellular communication and hormonal activity at the site of the infection, which causes redness and swelling.
Answer:
it's A
Explanation:
USATestprep
The statement that best describes the symptoms of redness and swelling at the site of a splinter after its removal is the interactions of the circulatory and immune systems create an increased blood flow and immune cell metabolism, which causes redness and swelling.
What do you mean by Pathogen?Pathogens may be defined as microorganisms that are responsible for the causation of various diseases, infections, and disorders.
When a splinter attacks your body, your body identifies that it is a foreign substance, it will activate the immune response through the skin and causes redness in association with the circulatory system by increasing the blood flow.
Therefore, it is well described above.

Research and find a zoonotic disease that you find interesting. Write a news report that could be used as a script for a TV news show.
Instructions
Include the following in your report:
Explain what a zoonotic disease is.
Describe the disease.
Explain how to protect yourself from becoming infected.
Your report should be 100 to 125 words long.
I need a little help i will mark you branleist
Zoonotic diseases are animal diseases that can be transmitted to humans. Transmission can be by ingestion, inhalation, bites, scratches, contact with contaminated products, and vector-borne. There are over 200 zoonotic diseases that can possibly threaten your health and involve several different causative agents, such as bacteria, parasites, viruses, and others. I am only going to inform you of just a hand full that is caused by bacteria and contaminates cattle. Once the cattle on large commercial farms become infected it can be a challenge to get rid of and contain.
Wash hands before and after animal handling.
1. Do not eat or drink in the animal housing areas.
2. Wear coveralls, farm specific clothing or laboratory coats when handling animals.
3. Avoid handling sick animals or animals with lesions unless gloved.
4. Wear a mask if you are allergic to animal hair or dander or if feed or bedding dust is present.
5. If you are sick, DO NOT enter the agricultural animal facilities. You are more susceptible to other infective agents and you may transfer pathogens to the animals!
6. Routinely wear gloves when cleaning animal area.
7. Note progression of any illness. Report illnesses to your supervisor.
8. Inform physician of your animal related activities.
