Scavengers are an organism that mostly consumes decaying biomass.

Detritivores feed on decaying organic matter and return essential nutrients back to the ecosystem.

So the answer would be (D). Both organisms feed on pieces of other dead organisms.

The diploid number of chromosomes in the mustard plant, Arabidopsis thaliana, is 10. Knowing this, answer the following question

Maslowich

Answer:

10 chromosomes

Explanation:

Ten (10) chromosomes would be found in each cell of Arabidopsis thaliana during prophase.

The prophase stage represents the first stage of the mitotic division immediately after the interphase. A diploid cell has 2n number of chromosomes and the ploidy level of a cell remains intact throughout the interphase to the prophase stage of mitosis.

At the prophase, the chromosomes of a cell only condense and become visible under the microscope. Each chromosome is seen as being consisting of two sister chromatids joined together by a structure known as the centromere.

Hence, the number of chromosomes in the cells of Arabidopsis thaliana would remain the same even at the prophase stage of mitosis.

Dentify the relationships between the zooxanthellae and the hard coral, the remora and the manta ray, the tiger shark and the gr

sergeinik [125]

Answer:

1. Mutualism

2. Mutualism (it was previously thought to be a case of commensalism)

3. Predation

4. Competition

Explanation:

1. Zooxanthellae and hard coral - Mutualism

These two organisms live in symbiosis. This means that both benefit each other. Zooxanthellae allow corals to gain energy through photosynthesis and, in turn, they receive important nutrients that are produced during the metabolism of the hard coral.

2. Remora and manta ray - Mutualism

Remoras and manta rays benefit each other. Remoras attach to manta rays mainly for transportation and feeding, but they also do it for protection. In turn, they make sure manta rays are clear from harmful bacteria and parasites. Several years ago, it was thought that manta rays didn't gain any benefit from remoras, so this was thought to be a case of commensalism. However, research has shown that they both benefit from each other. Therefore, this is also a case of mutualism.

3. Tiger shark and green sea turtle - Predation

In some areas (not everywhere) tiger sharks feed upon green sea turtles. For example, in Hawaii, have been observed to attack green sea turtles and feed on them. Researchers have spotted numerous sea turtles with characteristic tiger shark bites.

4. Dolphins and school of trevallies - Competition

Trevallies are large species of fish that feed on small schools of fish like dolphins. They both have their own predatory strategies that involve planning and gathering to catch large amounts of fish. Therefore, trevallies and dolphins compete for small schools of fish.

The frequency of a drum note is 20Hz. what does this tell you about the drum skin movement

Sergio [31]

Answer:

The drum skin oscillates 20 times per second

Explanation:

The frequency of a note is dependent on the mechanical activities that occur when it is produced. A drum is beaten in this case. The oscillation of the drum skin transfers sound waves to the air particles which move at the same frequency before reaching our ears.

If the frequency of the sound wave is 20 Hz this means that the wave is oscillating 20 times in one second. For the drum to produce such a sound, the skin must have been oscillating at the same frequency of 20 oscillations per second too.
