Please explain, why do we age?
Answer:
According to this theory, aging occurs through small and random damaging events in a cell that add up over time. These damaging events may come from our own metabolism, as the basic mechanism of metabolism sometimes causes damage to molecules within our cells.
Answer:
according to this theory, aging is caused by changes in hormones.
Explanation:
hormones are which are produced by the endocrine system.

Which best describes chromosomal dilatation
Answer:Changes that affect the structure of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can affect many genes along the chromosome and disrupt the proteins made from those genes.
Structural changes can occur during the formation of egg or sperm cells, in early fetal development, or in any cell after birth. Pieces of DNA can be rearranged within one chromosome or transferred between two or more chromosomes. The effects of structural changes depend on their size and location, whether gene function is interrupted, and whether any genetic material is gained or lost. Some changes cause health problems, while others may have no effect on a person's health.

What is the difference between emphysema and asthma?
Emphysema is an inflammation of the lungs, while asthma is a bacterial infection of the lungs.
Emphysema is the gradual destruction of the alveoli, while asthma is a sensitivity to irritants that causes the airway to constrict.
Emphysema is a sensitivity to irritants that causes the airway to constrict, while asthma is the gradual destruction of the alveoli.
Emphysema is a bacterial infection of the lungs, while asthma is an inflammation of the lungs.
Answer:
Asthma and COPD are both chronic lung diseases. COPD is mainly due to damage caused by smoking, while asthma is due to an inflammatory reaction. COPD is a progressive disease, while allergic reactions of asthma can be reversible.With asthma, the swelling is often triggered by something you're allergic to, like pollen or mold, or by physical activity. COPD is the name given to a group of lung diseases that include emphysema and chronic bronchitis. Emphysema happens when the tiny sacs in your lungs (called alveoli) are damaged.
Explanation:

What term best describe the role of carbon dioxide in the human body
Answer:
Carbon dioxide is essential for internal respiration in a human body. Internal respiration is a process, by which oxygen is transported to body tissues and carbon dioxide is carried away from them. Carbon dioxide is a guardian of the pH of the blood, which is essential for survival.

why was it impossible to know about bacteria 5,000
years ago
Answer:
Im assuming because microscopes hadnt been invented. Also the idea of communicable diseases wasnt around so people assumed it was things like god that caused illness
Answer:
A true understanding of the physiology of these bacteria and their roles in ecology, host health, and natural product production requires their cultivation in the laboratory. Recent advances in growing these species include coculture with other bacteria, recreating the environment in the laboratory, and combining these approaches with microcultivation technology to increase throughput and access rare species. These studies are unraveling the molecular mechanisms of unculturability and are identifying growth factors that promote the growth of previously unculturable organisms. This minireview summarizes the recent discoveries in this area and discusses the potential future of the field.
Explanation:
Which parts of a plant or animal contain the genetic information for characteristics like this?
All plants and animals are made up of cells where the genetic material can be found in the form of genes and chromosomes (usually in the nucleus).
Imagine that you took a small population of A. cooki lizards and moved them to a new island that was heavily forested. Predict what would happen over time to the color of the dewlap in that population of lizards. Using your knowledge of natural selection and genetics, explain your prediction.
a. Find out reasons for similarity and dissimilarity
b. Which types of reproduction are followed in sugar cane plant and in mango tree?
Sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.
Sugar cane is usually reproduce by using asexual reproduction i.e. by the use of pieces of stem of sugar cane called setts that contain at least one node. It is necessary that these cuttings contain a node because when they are placed and covered in the ground, primary roots arise from these nodes.
While on the other hand, the mango trees can be propagated both by sexual and asexual reproduction. Sexual reproduction involves the fusion of male and female sex cells during flowering stage. Grafting, Cutting, Layering and Budding are the asexual means for the propagation of mango tree.
Among these the grafting technique is considered as the most suitable method of vegetative propagation of mango so we can conclude that sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.

Why is farming good for the society? (Economic growth related) please give me scientific questions, I will mark you as brainly. Thank you
Answer:
Agriculture gave people the opportunity to create civilizations, fight hunger and work to combat challenges in population growth and climate change.
Explanation:
Another positive development in farming is the rapid expansion of farmers markets. Farmers markets allow small farmers to interact directly with consumers. The food system remains within the local economy by being locally produced and eliminates the need for long-distance transportation. The opportunity to purchase locally grown food proves invaluable as the demand for it rises.

Which definition is the best for “semipermeable membrane”?
It is a barrier that prevents materials from moving from one side to the other.
It is a barrier that allows materials to move freely from one side to the other.
It is a barrier with tiny openings that let some, but not all, materials pass through.
It is a barrier that helps materials move from one side to the other.
Answer:
C
Explanation:
Semi means partly
permeable means allowing liquids or gases to pass through it
Semipermeable means allowing some, but not all, liquids or gases to pass through it.
Answer:
c) It is a barrier with tiny openings that let some, but not all, materials pass through.
Explanation:
The prefix "semi-" means "some; partially". "Permeable" means "allow to pass through". Using your knowledge of the purpose of the membrane and the meaning of the word "semi-permeable", you would use context to come to the conclusion that the correct answer is c) It is a barrier with tiny openings that let some, but not all, materials pass through.
