Wrong carbon dioxide goes into the plants leaves and comes out as fresh air
Answer:
The correct answer will be- true.
Explanation:
The small intestine is the longest part of the gastro-intestinal tract which helps in the absorption of nutrients from the digested food.
The structure of small intestine contains cell membrane extensions called villi and micro-villi which increases the surface area for absorption. The small intestine increases the food absorption by peristaltic movement of the food chyme. The small intestine causes the food chyme to form spirals which passes the food to large intestine.
Thus, true is the correct answer.
Answer:
The colonies are carrying the resistance genes from plasmids
Explanation:
Bacteria can acquire beneficial characteristics that they didn’t have. One way for these is through plasmids, which ones are little fragments of DNA that usually contains resistance genes (for antibiotics, disinfectants, heavy metals, etc.) or other capacities, like the ability to use some substances (for example sugars).
In this specific situation, we already know that the plasmid carrying genes for tetracycline resistance and the <em>lacZ</em> gene.
A little explanation:
Tetracycline is an antibiotic that inhibits bacterial growth and kills the bacteria. The bacteria can “fight” to this antibiotic if it has a resistant gene, the result is that the antibiotic can’t affect the bacteria and survive. An analogy is like a Police Officer (bacteria) that have a bulletproof vest (tetracycline-resistant gene) so the bullets (tetracycline) didn’t affect the police.
In the case of X-gal, is a compound consisting primarily in one sugar called galactose. Not all bacteria can eat galactose, they need an enzyme called β- galactosidase (comes from <em>lacZ</em> gene) that helps the bacteria “eat” the sugar (cuts the sugar in little pieces so the bacteria can eat).
Then, as the bacterial colonies can grow in the medium with tetracycline and X-gal, we know that those bacteria are carrying the resistance genes for tetracycline (does not affect the bacteria) and the <em>lacZ</em> gene (bacteria produce β- galactosidase that cuts galactose). These genes are coming from the plasmids because we already know that the plasmid carries these genes and not from the exogenous DNA.
Answer:
It will remain a part of the environment
Explanation:
Energy cannot be destroyed but can change from one sate to another. Usually in a food chain animals eaten and the energy is passed from one animal to the next. In the case of larger animals the energy is only made available is they pass away or lose an appendage such as a tooth or antlers, that other animals can feed on.
If a shark is not preyed on and remains in the ecosystem, it's energy will not be cycled but this animal will get larger and larger.
Should a shark pass away and nothing feeds on it there are two things that will happen:
- Energy will be stored and the animal will eventually become volatile or slowly disintegrate and the energy will be released from the atoms and molecules when the bonds are eventually broken by chemical reactions brought on by the environment (sun. wind, currents, etc).
- The animal will eventually solidify and may turn into stone. The energy will be locked into the animal and will be encased and become a part of the substrate
It is not likely that a shark will keep it's energy and not be eaten by other animals after death but on the chance that it does it may slowly disintegrate or become solidified.
