There are both physical and biological limiting factors found in nature.
-Physical factors (abiotic factors) include temperature, water availability, oxygen, salinity, light, food and nutrients.
-Biological factors (biotic factors) involve interactions between organisms such as predation, competition, parasitism and
herbivory.
The answer to this question would be: by producing buffer
The pH of optimal growth of bacteria might be different. Some bacteria can grow in an acid condition called acidophile, other live in base condition called alkaliphiles and the rest live in neutral pH condition called neutrophiles. The bacteria can maintain their internal pH by producing acid, base or buffer. If the surrounding pH is too acid, the bacteria can reduce the H+ concentration by producing base. If the condition is too alkali/base, the bacteria can produce acid by doing fermentation.
Answer:
Both gene expression and DNA micro array study about the expression of gene during different stages of development.
Explanation:
The main purpose of gene expression studies is to determine the level of mRNA expressed at different stages of transcription in a tissue or at different stages of cellular development. If a gene is not “ON” during synthesis of RNA and protein, then the desired proteins are not produced. Such studies allow us to turn on such genes.
DNA microarray assays easily identify and determine the network of gene expression across the entire genome. The common application of DNA microarray include – mutation analysis and detection, assessment of gene cop, immunoassays etc.
Answer:
A
Explanation:
Conduction is the exchange of energy as warmth or power starting with one iota then onto the next inside an article by direct contact. Conduction happens in solids, fluids, and gases. Nonetheless, solids move energy most proficiently since the atoms in solids are most firmly stuffed, and the particles are nearer together, as displayed in this figure. For fluids and gases, the thickness of the particles are by and large lower than those of solids and the particles are farther separated, so the energy move is less productive.
