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.
This statement is true. For example animals are heterotrophs and they obtain energy through cellular respiration.hope it helped you .Please mark as the brainliest answer if it helped.
Answer:
Random segregation of homologous chromosomes makes the two siblings differ from each other for 0-23 chromosomes.
Explanation:
Sexual reproduction adds genetic variations in the progeny by crossing over, independent segregation of homologous chromosomes and random fusion of gametes. Without crossing over, independent segregation of homologous chromosomes towards opposite poles during anaphase I of meiosis may result in two siblings to vary from each other for 0-23 chromosomes.
There is an equal probability of each of the two siblings to get a chromosome from mother or father. Hence, irrespective of the variations provided by crossing over, random segregation of homologous chromosomes makes the two siblings differ from each other for 0-23 chromosomes.
If you are asking if it is a true or false statement, it is a false statement. A mutation cannot possibly occur during polypeptide production or any protein synthesis or process. However, mutation may occur if the protein or enzyme is involved in any DNA replication or transcription process.
