Clubfoot describes a range of foot abnormalities usually present at birth (congenital) in which your baby's foot is twisted out of shape or position. In clubfoot, the tissues connecting the muscles to the bone (tendons) are shorter than usual.
1. Enterococcus and coliforms can enter the water through feces. Although a water sample is negative for these bacteria, it could still be infected by pathogens from other sources than feces.
2. Culture media are sterilized by filtration because they could contain antibiotics or serum which deteriorate upon heat. Filtration is used in sanitation to remove large particles.
3. In the membrane filter technique, it is assumed that <span>all viable bacteria will form colonies. This means that formed colonies develop from the viable bacteria so that the number of colonies suggests the number of bacteria.
4. E. coli is negative for Citrate and Voges-Proskauer tests, and is positive for Indole and Methyl red tests.
5. The answer is yes because eo</span><span>sin-methylene blue agar is inhibitory to Gram+ bacteria.</span>
Mortality, or death rate is a measure of the number of deaths in a particular population, scaled to the size of that population, per unit of the time. In this case a factor that would result to an increased mortality rate in a population due to increased competition of water will be the density-dependent factor.
Binary fission is the process of a bacterial cell going from singular to double. Therefore the correct answer would be: "During binary fission, a bacteria cell grows in size because DNA and other organelles are duplicated."
Graduating from high school this year makes me feel a bit sad. Biology was such a fun but crazy class.
Enough of my sentiments; I'm here to help, :-).
This answer is dependent upon what ecosystem you choose your project over.
So, abiotic factors are nonliving things in an ecosystem. Biotic factors are living organisms and anything alive.
For instance, if you choose a pond for your ecosystem then the water, soil, maybe trash would be abiotic factors. Some could argue there is living material within the water and soil but those abiotic factors are not alive. I mean water is not alive but it could be a home to biotic factors like microorganisms such as protozoans and worms. The grass and trees and animals around a pond would be biotic factors.
Hope you get the idea. if there's any questions then leave a comment and I'll help. Good luck!
