Answer:

c) Archaea

Explanation:

Los dominios biológicos son los taxones de más alto nivel, por encima de los reinos y abarcando todos los taxones, caracterizándolos de la manera más generalizada posible, dentro de la clasificación científica. Hay tres tipos de dominios llamados Archaea, Bacteria y Eukarya. Entre ellos, el dominio conocido como Archaea es el que engloba a los organismos procarióticos, unicelulares y patógenos, es decir, capaces de provocar enfermedades en el ser humano.

How do you write 2-3 paragraphs on evolutionary history/advances from the monerans to protists to fungi?
Lyrx [107]

Kingdom Monera was the oldest kingdom of living organisms. The organisms in the kingdom were simple, single celled and their cellular organelles were not covered by membranes. Prokaryotic bacteria were the first known Monerans. However, scientists think that Monerans were evolved into more complex eukaryotic organisms (Protists) with the passage of time.  

But how did Monera (Prokaryotes) was evolved into Protista (Eukaryotes)?

  • Monerans to Protists

Protista are eukaryotes, unicellular or simple multicellular organisms.Many theories were proposed for this evolution, but one that makes most sense was endosymbiotic theory. According to this, the first eukaryotic cells were evolved when two prokaryotic cells existed in an endo-symbiotic relationship. Larger prokaryotic cells engulfed smaller prokaryotic cells. The smaller cells got shelter and nutrients from larger cells and both co-existed in a mutualistic relationship. Both cells eventually evolved into organelles and got never aparted. This is how more complex organisms’ protists were evolved from simple monerans. It was a gradual process and took millions of years.

  • Protists to Fungi

The earliest fungi were single-celled organisms that contain a flagella to move from one place to another. Recent studies indicate that fungi belong to a group of organisms which were evolved from protists over the course of time. These studies are based on the nucleotide sequence of fungi that matches to a large extent with old protists. It is estimates that fungi evolved 600 million years  or even before.

At the end of cytokinesis, how many daughter chromosomes will be found in each cell
trapecia [35]
At the end of cytokinesis there no longer exists chromatids, they are just individual chromosomes.

If you're talking about Meiosis, there are 4 (HAPLOID) daughter cells produced at the end of meiosis. So each daughter cell will have HALF the number of chromosomes as the mother cell.

Whereas at the end of Mitosis there are 2 identical DIPLOID sister cells.

How have increased carbon dioxide levels and temperatures affected living organisms?
d1i1m1o1n [39]

Answer:  

Carbon dioxide is a gas which is released in the atmosphere as greenhouse gas, burning of fossil fuel, released in respiration process. Rise in the levels of carbon dioxide and other gases has resulted in increase in global temperatures. Increase in carbon dioxide and temperatures are responsible for weather fluctuations and global warming.

Weather fluctuation means untolerated heat and lack of precipitation or rain. Weather fluctuations will affect seasons. Seasons are necessary for maintaining the life cycle of organisms. Inappropriate seasons due to climatic change will affect the life of living organisms.

Global warming is an issue which is mainly due to release of hot heat trapping  gases from green house and other sources, increasing the atmospheric temperature. This will result in melting of ice from glaciers in world. The inhabiting animals living in the glaciers will suffer a lot from this as they cannot tolerate warm climatic conditions.

If a post synaptic neuron is stimulated to threshold by spatial summation this implies that ________. the postsynaptic cells has
Valentin [98]

Answer: The postsynaptic cells has many synapses with many presynaptic neuron.

Synapse can be defined as a structure that allow neuron to send a chemical or electrical signal to another neuron. However, postsynaptic potential is a temporary change in the electrical polarization of the membrane of a nerve cell and they are known to be receiver of neurotransmitter message.
