Answer:

Internal environmental factors are events that occur within an organization. External environmental factors are events that take place outside of the organization and are harder to predict and control.

Can we detect bacteria in pollutants using DNA profiling
Blababa [14]
Yes. You could do this by adding solvents to break down any cell walls, centrifuge to separate the DNA, if you haven't got much then upscale with PCR, gel electrophoresis could be used to detect the DNA, and Sanger sequencing to find the sequence.

On a backpacking trip, Kenny hikes all day at a steady pace, covering 30 kilometers and burning 4000 Calories. At the school tra
emmasim [6.3K]

Answer:

A. If the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt."

D. The rate of energy demand determines how the muscles will obtain energy, either from cellular respiration or from lactic acid fermentation if not enough oxygen is present.

Explanation:

It is important to consider that Kenny hikes all day but at a steady pace, whereas Janelle runs very fast. So Kenny's case, the supply of oxygen is sufficient to maintain aerobic respiration within the muscle cells. During this process only CO2, Water, and ATP are produced; therefore, there is no oxygen debt. We should keep in mind that the body shifts to anaerobic metabolism only when the supply of oxygen is limited.

In Janelle's case, running fast would need energy at higher rates and the supply of oxygen would not be sufficient to generate a high amount of ATPs. Therefore, to compensate for this deficiency, cells will start fermenting glucose to lactic acid and produce ATP and maintain energy demands. This lactic acid causes fatigue and this is why Janelle has aching and breathing hard. Breathing hard is also automatic reflux to inhale more oxygen and meet oxygen demands but even breathing hard would not be able to make it and the body will shift to anaerobic respiration automatically.

Which best explains how binary fission contributes to the genetic continuity of a population? A Binary fission maintains genetic
kozerog [31]

Answer:

B Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.

Explanation:

Genetic continuity ensures that genetic information is passed from one generation to another in correct way so that the resultant progeny has the complete set of genes required for survival. For example, at the end of mitosis, daughter cells should have the same number of chromosomes as parent cell.

Binary fission is a method of reproduction in some organisms like bacteria. It is an asexual mode of reproduction in which the parent cell splits into daughter cells without the process of fusion with another cell. It still maintains genetic continuity because the daughter cells are identical to the parent cell and thus have same number of chromosomes and type of genes.
