Answer:
See the answer below
Explanation:
Science is a body of knowledge through which humans try to understand the natural world and make the best out of it. The usefulness of science can be seen from its applications. Some of these applications include;
1. Health: through science, humans have been able to gain insights into the causes of various diseases and profer solutions to them. The continuous investigation into diseases and drugs have ensured that the human population remains healthy to an extent.
2. Food and Agriculture: scientific advancements have ensured the domestication of useful plants as foods, drugs, or industrial materials. Through biotechnology, improved breeds of crops have been produced and sustainable food production for the human populace has been promoted.
3. Improved lifestyle: Advancement in science has helped man to be able to live an improved lifestyle. The application of scientific knowledge has led to the invention of products that can automate processes that otherwise would have been done manually. Examples include the invention of vehicles, washing machines, grinders, air conditioning, etc.
4. Communication: Science has also revolutionized how humans communicate with each other. The discovery of waves and how they can be manipulated for improved communication has led to the invention of phones, radios, televisions, and so on.
5. Infrasctures and aesthetics: Through various advancements in science, infrastructural facilities for improved living experience and beautification of the environment for aesthetic purposes have been incoming.
Answer:
Liver.
Explanation:
The liver is a dark reddish organ that is situated in the right hypochondriac or upper right hand region of the abdomen, just below the diaphragm and anterior to the stomach in the epigastric region, the right kidney and the small intestines.
It is the second largest organ of the body, second only to the skin. The liver is divided into four lobes which include;
1) The right lobe
2) The left lobe
3) The quadrate lobe and
4) The caudate lobe
The blood supply to the liver include;
1) The hepatic artery
2) The hepatic portal vein which supplies the liver with nutrients-filled blood from the small intestine. It is the main blood supply to the liver.
The venous drainage is through the hepatic veins.
The nerve supply is through the hepatic plexus made up of sympathetic and parasympathetic nerves.
The liver plays a major role in the processing and metabolism of food and ingested substances and also detoxification.
Answer:
the results of the investigation led to new scientific questions
Explanation:
The basis of every scientific question asked is an observation made. Scientific questions are questions that emanate from an observed problem and leads to the formation of a testable explanation (hypothesis). In this question, an investigation was made by a scientist and it was discovered that increased temperature decreases the number of offspring that an organism produces.
However, the scientist asks a new question about the impact of climate change on the species. This is because an observation has been made again, from the previously concluded investigation. Hence, after completing the investigation about the effect of temperature on the number of offsprings an organism can produce, an observation was made, ultimately leading to a new scientific question.
Answer:
The correct answer is - eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.
Explanation:
Self-testing in the immune system is a very important step as it helps in analyzing if the immune cells or lymphocytes. To fight against the intruders, the immune system should initially recognize them. That is, the immune system must have the option to recognize what is nonself (remote) based on what is self. The immune system can make this identification since all cells have distinguishing recognition molecules (antigens) on their surface.
Self-test helps in identifying and eliminate in all lymphocytes that have built and attack the healthy cells and killing them.
