1. The general trend of human population growth is that the growth rate of population is increasing over the years .

2. Countries of the world differ in birth rates, death rates and age structure of population and this factor explains why population  in different countries grow at  different rates.

3. Demography is the study of human population in terms of births, deaths etc is called demography.

4. Demographic transition is the shift from high birth and death rates to high birth and low death rates and finally to low birth and death rates. Demographic transition reduces the rate of population growth of a country.

5. Age structure diagram contains data about individuals who belong to the younger age group. Once they become mature they will contribute to population growth and thus studying the age structure gives an idea the trends of future population growth.

Which of the following could result in the extinction of a species?
mylen [45]

Increased population size will result in the extinction of a species of organisms.

<h3>What is Extinction?</h3>

This is defined as the dying out or disappearance of species as a result of various factors.

When population size increases, it leads to unavailability of food and reduction of species due to starvation and death.

Beyond their role in energy transfer, what other benefit do microorganisms that act as producers provide for ecosystems?
insens350 [35]

Answer:

The microorganisms present metabolic wastes that serve as the primary source of food for other living things.

Bacteria that live free in the soil or in symbiosis with plants are essential to fix nitrogen, both nitrates and ammonia. These bacteria take nitrogen directly from the air, originating compounds that can be incorporated into the composition of the soil or living beings.

This property is restricted only to prokaryotes and is widely distributed among different groups of bacteria and some archaeobacteria. It is a process that consumes a lot of energy that occurs with the mediation of the enzyme nitrogenase, which the rest of the living organisms that cannot do or comply with this process is because they lack said enzyme.

Dunaliella is a genus of microscopic algae of the Chlorophyceae class and of the order Volvocales. All are unicellular, although with very varied morphologies.

Morphologically, its main characteristic is that they lack a rigid polysaccharide cell wall.

The ecology of this genus of green algae is characterized by its high tolerance to salinity, with eukaryotic organisms having greater tolerance to salt. They are euryhaline, adapted to salt concentrations from 50 mM NaCl to almost 5.5 M NaCl.

Explanation:

By nitrogen fixation is meant the combination of molecular nitrogen or dinitrogen with oxygen or hydrogen to give oxides or ammonia that can be incorporated into the biosphere. Molecular nitrogen, which is the majority component of the atmosphere, is inert and not directly usable by most living things. Nitrogen fixation can occur abiotic (without the intervention of living beings) or by the action of microorganisms (biological nitrogen fixation). Fixation in general involves the incorporation into the biosphere of a significant amount of nitrogen, which globally can reach about 250 million tons per year, of which 150 correspond to biological fixation.

Because nadh generated in the cytosol cannot enter the mitochondrion, electrons and protons from nadh are transferred in by ____
klio [65]
I think the correct term to fill in the blanks would be glycerol phosphate electron shuttle. This shuttle is responsible of transporting agents that are reducing into the inner membrane of the mitochondria. Since NADH cannot enter, it is reduced so that the electrons could go in to the transport chain.
