Define a preditor-prey relationship? How if affects the food chain?

Biology

Predator prey relationship, is just basically when the predator eats the prey. Like for example if cheetah eats the zebras, through time zebras can become less of a population. But then think of this, if there was NO prey zebras could over populate and there may not be enough places for them to live or enough food. Hope that helped...

Answer:

For growing bacteria it is necessary water, a source of carbon and nitrogen, some inorganic salts.

Explanation:

There are plenty of kind of bacteria, even, all of them need water to dissolved their nutrients and to remove the wastes outside of the bacteria body. The source of carbon could be carbon dioxide for some bacteria that do not need a lot of it. In the other hand, there are other bacteria that are feed based on glucose, fructose or another carbohydrate.

Nitrogen sources normally come from air as gaseous element or some inorganic salts like nitrates.

Other bacteria need specific elements like phosphorous, sulfur, zinc, copper, etc.

Hope this info is useful.

what is the process of photosynthesis; what is the one component in photosynthesis that is not recycled and must be constantly a
Ugo [173]

Green plants and certain other animals use a process called photosynthesis to convert light energy into chemical energy. Sunlight is the primary, non-recyclable, and easily accessible component of photosynthesis.

In the electromagnetic radiation that the Sun emits, sunlight is included. Water (H2O) and carbon dioxide (CO2) are ingested by plants during photosynthesis from the soil and atmosphere. In contrast to carbon dioxide, which is reduced within the plant cell and obtains electrons, water is oxidised within the cell of the plant. Due to this, carbon dioxide and water are converted into glucose and oxygen, respectively.

We can therefore conclude that green plants and some other animals convert light energy into chemical energy through a process known as photosynthesis. The most important, easily accessible, non-recyclable element in photosynthesis is sunlight.

What is happening to the DNA molecule in the figure?(Explain the first step in DNA replication)
Talja [164]

Answer:

As this is DNA replication, this is the unwinding process

Explanation:

In DNA replication, the parent DNA to be replicated is unwound to enable access of the replication machinery (replisome) to this genetic material. The origin of replication will be identified first, which in the prokaryotes is only one, and in the eukaryotes, we have many. This sites are recognized by specific sequences on the genome. after this, melting of the DNA occurs at this origin creating a replication bubble and two replication forks. This  allows for the unwinding of the DNA by the enzyme Helicases in the direction of the replication fork. Another enzyme present in this step is also the single strand binding proteins (SSB). These proteins function in the prevention of re-annealing of the unwound DNA strand by attaching themselves to each strands. Another enzyme called the topoisomerases also function here by reducing the torque (twisting) produced upstream of the replication fork as result of DNA unwinding. An example is the gyrase.
