External appendages that stick to other cells and surfaces, which may give rise to aggregates known as biofilms and colonization of microbes on inanimate objects, are known as fimbriae.
What are biofilms?Bacterial biofilm is a major cause of medical device contamination and the spread of infectious and chronic diseases throughout the body. Biofilms, in generally, are the genesis of a variety of human diseases, as they can lead to significant infections and are resistant to antimicrobial drugs.
Fimbriae are long filamentous polymeric protein structures present on bacterial cell surfaces. They allow bacteria to fuse to specific receptor structures and colonize specific surfaces as a result.

how does transpiration help in obtaining clean water?
Answer:
When plants absorb water from the ground they filter out many impurities, and you can extract this clean water from them. Plants transpire water, meaning that water vapor evaporates from the leaves, and this water can be collected.

2. (b) Why is it important to maintain genetic diversity in populations?
Genetic diversity encourages the health of a species and provides material resources such as plants. The loss of genetic diversity leads to reduced options for mates which means even more loss of a species and the species becomes more susceptible to disease. These are very few results that occur with the loss of genetic diversity.

What is Paris Agreement?The Paris Agreement deals with production of those types of energy which is clean and which don't emit (or emit very less) green house gasses, the root cause of climate change and global warming.The term climate change has to do with the alteration of weather patterns owing to the release of harmful gases commonly called greenhouse gases.
The main goal of the Paris Agreement is to strengthen the global response to the threat posed by climate change by limiting the rise in global temperature this century to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to further limit the temperature increase to 1.5 degrees Celsius.
Therefore, The groups which are likely to benefit from the Paris agreement are solar power companies, and hydroelectric dam engineers. Thus, option A and B are correct.

D Need more information.
Answer: i would say for number 2 its A and number 3 D
Explanation:
for number 2 its A and number 3 D.
What is Potential energy difference?The work done on q by the electrostatic or Coulomb force is independent of the direction taken because it is a conservative force. The gravitational force in the absence of dissipative forces like friction is exactly identical to this.
When a force is conservative, it is possible to define a potential energy that goes along with the force. Because the potential energy varies solely on position, managing it is typically simpler than calculating the work directly.
Electric potential energy and gravitational potential energy are quite similar. Without having to interact directly with the force, potential energy accounts for the work carried out by a conservative force and provides additional insight into energy and energy change.
Therefore, for number 2 its A and number 3 D.

What should scientists do when a new discovery is made that goes against a long-accepted theory?
He should analyze and compare his findings with findings already accepted within the scientific community.
What is theory?A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.
A theory not only explains known facts as it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory. If it isn't, the theory is refined or rejected. The longer the central elements of a theory hold the more observations it predicts, the more tests it passes, the more facts it explains the stronger the theory.

what is inside your capillaries that carries oxygen to your heart?
Answer:
Capillaries are narrow blood vessels. Blood contains plasma, red blood cells, white blood cells and platelets. Red Blood cells are bi-concave disc which contains hemoglobin that reacts with oxygen and thus oxygen is transported by RBC to the heart where it is distributed to the whole body
Veins are present inside your capillaries that carry oxygen to your heart. While arteries perform the opposite function which carries blood away from the heart.
What are the functions of capillaries?The functions of capillaries are as follows:
Capillaries transport blood, oxygen, and nutrients to every cell. They are the type of delicate blood vessels that exist throughout your body. They also exchange waste throughout the body.Capillaries also help in the connection of arteries and veins.Capillaries are the connection link of both arteries and veins. So, both arteries and veins perform their specific function in order to facilitate the transport of deoxygenated blood and oxygenated blood to and from the heart respectively.
Therefore, the structure inside your capillaries that carries oxygen to your heart is known as veins.
