The cell nucleus, could be up there as the nuclei
Theory of spontaneous generation
Explanation: Theory of spontaneous generation stated, life arose from non-living things. Pasteur disprove this theory by S-shaped tube experiment. He used swan-neck flasks (twisted necks) and filled them with sterilized beef broth
The right answer is hydrophilic.
Phospholipids are amphiphilic lipids which means that one side is hydrophilic (the glycerol phosphate portion) while the other side is hydrophobic (fatty acids). Thus, if placed in water, the phospholipids will be organized in such a way that only the hydrophilic zone will be in contact with the water. If they are forced to mix with this liquid, they will form a lipid bilayer in which the hydrophobic fatty acids face each other. The plasma membranes of cells and organelles are moreover constituted in this way.
Answer:
Cellular respiration is a set of metabolic reactions and processes that happen within the cells of organisms to convert energy from oxygen molecules or nutrients into ATP (ATP), then release waste products.
Answer:
Speciation didn't occur over the past 10,000 years
Explanation:
We conclude this, since the two populations could mate (if speciation occurred, there would be no reprodution).
For example, in allopatric speciation which occurs as a result of geographic isolation, the part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed (reproduction between them) which means they become two different species (speciation).
New populations evolve as result of mutation, genetic drift and natural selection.
