How abundant are plankton?

Biology
1 answer:
lara [203]3 years ago
6 0

Answer:

While plankton are most abundant in surface waters, they live throughout the water column.

Explanation:

Plankton inhabit oceans, seas, lakes, ponds. Local abundance varies horizontally, vertically and seasonally. The primary cause of this variability is the availability of light. All plankton ecosystems are driven by the input of solar energy (but see chemosynthesis), confining primary production to surface waters, and to geographical regions and seasons having abundant light.

During a nuclear reaction, an isotope of a certain atom gives off a particle consisting of two protons and two neutrons, and the
aev [14]

Answer:

Type of radioactive decay which has occurred is an alpha decay.

Explanation:

Type of radioactive decays:

  • Alpha decay is defined as the decay process in which alpha particle is released. In this process, a heavier nuclei decays into a lighter nuclei. The alpha particle released carries a charge of +2 units and a mass of 4 units.
  • Beta decay is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron. The released beta particle is also known as electron.
  • Gamma decay In this process, an unstable nuclei releases excess energy by a spontaneous electromagnetic process and gamma -radiations are emitted. These radiations does not carry any charge and are electrically neutral.

A farmer decides to go into the business of raising trout for tourists who enjoy fishing. She builds six trout ponds and stocks
Nastasia [14]

Yes the following statements about her trout is likely true Because the ponds are different and the populations are likely to experience different mutations, the populations will likely diverge evolutionarily, but only over many generations.

Explanation:

The effect of genetic drift can be seen in all populations but the most is seen in small population. The change in allele frequency due to the sampling error would lead to evolution of the species.

Bottleneck effect is when a population gets reduced due to some natural disaster. Her friends were not right about bottleneck effect.

So it is clear that no bottleneck effect will occur as each pond have different chance or rate of mutation and the change in alleles will be different. The  trouts will evolve independently in the different ponds and pass on the traits to their progeny.

Genetic drift does not take into account for the harm or benefit of the alleles that are passed on.

The amount of time spend in the bathtub and the temperature of the bath water

Hihi!

<span>In general the water should be kept around 100-105 degrees fahrenheit! You should only spend around 10 minutes in the bath at a time, long bathes and showers damage your skin and take out all the moisture in your skin as well!

I hope I helped!
