I think the correct answer from the choices listed above is option D. Simple diffusion is the cell transport that allows small molecules to move from an area of higher concentration to an area of lower concentration without energy being <span>required from the cell.</span>
If fertilizers enter the St.Johns river they will result in nutrient overload, or eutrophication and harming the ecosystem of the river. The river will exceed its assimilative capacity for nitrogen and phosphorus. this will <span>deplete oxygen in the water needed by fish and reduce light that is essential to submerged vegetation. </span>
Answer:
The main difference between sieve tubes and companion cells is that sieve tubes are the long, narrow, pointed tubes present in the phloem of angiosperms whereas companion cells are attached to the sieve tubes, regulating the activity of sieve tubes.
Answer:
corrugated cardboard tube - digestive tract
irregular surfaces on the corrugated tube - villi
pump - heart
Plastic tubing - blood vessels
Explanation:
The corrugated cardboard tube represents the digestive tract. The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.
Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.
The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.
The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body
3 specific tasks you must do while working with Professor Ingo Potrykus on this specific project is plant hybridization, growth recognition and quality of the products obtained.
<h3>How is lineage improvement done?</h3>
The answer is to obtain populations with genetic variability. This can be achieved through hybridization or crossbreeding. Hybridization is the fusion of genetically different gametes, which results in hybrid individuals heterozygous for one or more loci.
With this information, we can conclude that 3 specific tasks you must do while working with Professor Ingo Potrykus on this specific project is plant hybridization, growth recognition and quality of the products obtained.
