He needs to be careful to document his sources about the problem of invasive species.
<h3>What is Invasive species?</h3>
- An introduced organism that overpopulates and damages its new environment is referred to as an invasive species.
- Even though the majority of introduced species are neutral or helpful to other species, invasive species have a negative impact on habitats and bioregions, harming their ecology, the environment, and/or their economy.
- Invasive species are one of the largest issues our natural environments have ever faced.
- Invasive species have the potential to proliferate rapidly in the absence of their natural predators, displacing native species, destroying ecosystems, and incurring high costs.
- This increase is frequently attributed to growing global trade, manufacturing specialization, and linkages to previously remote areas.
- Additionally, the extension of existing imported specie's ranges is made possible by climate change.

Fuel cells can make an electricity from a simple electrochemical
reaction in which oxygen and hydrogen combine to form water. There are several
different types of fuel cell but they are all based around a central design
which consists of two electrodes, a negative anode and a positive cathode.
These are separated by a solid or liquid electrolyte that carries electrically
charged particles between the two electrodes. A catalyst, such as platinum, is
often used to speed up the reactions at the electrodes. Fuel cells are
classified according to the nature of the electrolyte. Every type needs
particular materials and fuels and is suitable for any applications. The
article below uses the proton exchange membrane fuel cell to illustrate the
science and technology behind the fuel cell concept but the characteristics and
applications of the other main designs are also discussed. Proton Exchange Membrane Fuel Cells (PEMFC)
The hydrogen ions permeate across the electrolyte to the
cathode, while the electrons flow through an external circuit and provide
power. Oxygen, in the form of air, is supplied to the cathode and this combines
with the electrons and the hydrogen ions to produce water. These reactions at
the electrodes are as follows:
Anode: 2H24H+ + 4e-
Cathode: O2 + 4H+ + 4e- 2H2O
Overall: 2H2 + O22H2O + energy
PEM cells operate at a temperature of around 80°C. At this
low temperature the electrochemical reactions would normally occur very slowly
so they are catalysed by a thin layer of platinum on each electrode.
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. ... The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Explanation:
Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell
I think the correct answer from the choices listed above is the second option. The tissue where the food travel from the leaves to the bulb would be the phloem. It <span> is the living tissue that transports the soluble organic compounds made during photosynthesis.</span>
