Answer:
Immunity to Small Pox
Explanation:
Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.
As we know that the leaves of plants are waterproof due to cuticle. On the same way, take some pieces of paper of leaf size and make them waterproof. after completion, put half of these paper pieces in cold water and half in hot water. Do all the pieces of paper remains waterproof? Explain your observation and result with justifications
Answer:
its answer is:
No all the pieces of paper not remains waterproof. After making water into its pieces in the shape of leaves, it can't be able to defend water. As paper is non living thing and leave is part of living being so, paper is not waterproof but leaves is waterproof.

What is the role of RuBP? How is RuBP regenerated?
Answer: RUBP Regeneration refers to the cyclical process where the photosynthetic enzyme Rubisco fixes carbon dioxide into the sugars that fuel plant growth and productivity. Only one-sixth of the PGA carbon is converted to sugar—the rest of the carbon is used to recycle RuBP as the cycle continues.
Explanation:
Consider a major environmental change (like antibiotics entering a person's body). If there are not organisms in a population that have traits that allow them to still continue to survive to reproduce, what would likely happen to that population?
Answer:
The population (of the bacteria) will reduce
Explanation:
This question appear a little confusing because of the structure of the second sentence. However, it appears to describe how an antibiotic works. Antibiotics work against bacteria by either making the environment toxic for the bacteria (which kills it) or inhibiting the growth/reproduction of the bacteria. Both patterns will eventually lead a sharp reduction in the population of the bacteria. Even if what the antibiotic does is to inhibit the reproduction of the bacteria, this act provides the body with an opportunity to fight the "unreproductive" remnants of bacteria thereby leading to the reduction of population of the bacteria.

how can elevation greatly affect an ecosystem
Answer:
Elevation may affect the type and amount of sunlight that plants receive, the amount of water that plants can absorb and the nutrients that are available in the soil. As a result, certain plants grow very well in high elevations, whereas others can only grow in middle or lower elevations.

3. The suffix -ose means sugar. Is glucose a simple or complex
sugar/carbohydrate?
Answer:sugar
Explanation:
Answer: Technically both
Explanation:
Complex carbohydrates are found in foods such as peas, beans, whole grains, and vegetables. Both simple and complex carbohydrates are turned to glucose (blood sugar) in the body and are used as energy. Glucose is used in the cells of the body and in the brain.
What is the next phase of the carbon cycle for the carbon source labeled B? Label A shows a collection of coal, oil and gas. Label B shows a collection of trees and vegetation. Label C shows sky and open atmosphere. Condensation Transpiration Photosynthesis Decomposition
Answer:
Hi! so the answer is decomposition.
Explanation:
If you are looking at the graph and go to the carbon source labeled B and you look at the arrow to here soil organic matter points to you can see that it points to decomposition. Also because I took the test and got it correct. I hope you can mark me as brainleast. thank you :)
The next phase of the carbon cycle for the carbon source labeled B is known as decomposition. Thus, the correct option for this question is D.
What is the Carbon cycle?The carbon cycle may be defined as a type of biogeochemical cycle through which carbon and other derivatives prodcts of its continually travel from the atmosphere to the Earth and then back into the atmosphere.
According to the graph, the source of carbon that plants and trees get from the soil is the action of decomposers. These microorganisms significantly convert the organic form of the source into an inorganic form which is then easily consumed by the plants for their metabolic process and growth.
Therefore, the next phase of the carbon cycle for the carbon source labeled B is known as decomposition. Thus, the correct option for this question is D.
