Answer:
False
Explanation:
Humans all around the world has a body temperature similar, humans like all the mammals are endothermic (the body temperature is regulated for itself) animals, this means that our temperature doesn't change according to the climate.
Also the flow of the blood in our body changes according to the heart rate, while more bits per second our heart does, more blood flows in our extremities.
So it's false that human evolved in colder have more blood flowing into their extremities, and at a hotter temperature, than people living in warmer climates.
Answer:
The correct answer will be-
1. Chromosomes are made up of protein and nucleic acid.
2. Genes are located on chromosomes.
3. Chromosomes are found in the nucleus.
Explanation:
Watson and Crick are known for their findings on the structure of DNA in 1953. Their findings were motivated by the book called "What is Life?".
The book stated the concepts which were well accepted by the scientific communities that is the gene determines the trait which is located on the chromosomes proved by the experiments of Morgan.
The chromosomes are the condensed structure present in the nucleus was suggested by the Nageli in 1884. The chromosomes are composed of nucleic acid and protein was also proved and was well-accepted fact.
But the genes are made up of DNA was not well accepted which was suggested by the experiments of Avery in 1940s.
Thus, the selected options are the correct answer.
The organs that work together is called systems. It is a group of parts or organs that interact and work together for a common purpose or function. Each of the parts seems to depend to each other in order to achieve their shared functions and goals. When one of the organs in a system becomes dysfunctional, automatically the other parts cannot function as effective as they were during those times that everybody's in good condition becaus the condition of one organ in the system directly affects the others too.
