Answer:
How much lighter would a human be if we had hollow bones like in birds? about 10% lighter. most of our weight is muscle (water) and fat. bones are only about 20% of our body weight.
Explanation:
so no they are actually much lighter
Answer:
The correct answer is B-typically grow slower than in pure culture
Explanation:
In nature, microbes experience lots of challenges like challenges to get space, to live, to get food, to adapt to the changing environment, to get protection from their pathogens and predators, etc. So these all challenges affects the growth rate of microbes.
In pure culture only one type of bacteria is grown on a nutrient-rich media and a steady environment is given to them to grow. In pure culture, there are no predators and competitors for microbes.
So all this provide favorable condition for a microbe to flourish in a pure culture so the growth of an organism in pure culture is higher than in nature. So the correct answer is B.
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.
Darwin basically invented the word Natural Selection. I’m not sure what Pasteur did.
Answer:
hopes it helps
Explanation:
In glycolysis, glucose molecule is converted into pyruvate molecules .
It can't be cellular respiration because it starts always with glucose i.e glycolysis. But here it is the process after glycolysis (starting from pyruvate) and changing into lactic acid. It's an aerobic respiration called as lactic acid fermentation.
