Choose the true statement. a. Prokaryotic cells are larger than eukaryotic cells. b. Prokaryotes have membrane-bound organelles.
Cerrena [4.2K]

Answer: D) Prokaryotes are only Single Celled

A prokaryotes are single celled  or unicellular organism that do not have nucleus or other membrane bound organelle.

The size of prokaryotic cell normally ranges from 0.1 to 0.5 μm. The size of prokaryote are smaller than eukaryotes which ranges from 10–100 µm

Example: <em>E. coli</em>, <em>Streptococcus</em>

Although glycolysis produces four molecules of atp by substrate-level phosphorylation, the net gain of atp for the cell is two m
omeli [17]

Although glycolysis produces four molecules of atp by substrate-level phosphorylation, the net gain of atp for the cell is two molecules. This is because glycolysis is at first endergonic.

<h3>What is glycolysis?</h3>
  • The metabolic process that turns glucose into pyruvic acid is known as glycolysis.
  • The high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process.
  • A series of ten enzyme-catalyzed processes make up glycolysis.
  • The process by which glucose is broken down to provide energy is known as glycolysis.
  • It generates two pyruvate molecules, ATP, NADH, and water.
  • There is no need for oxygen throughout the process, which occurs in the cytoplasm of a cell.
  • Both aerobic and anaerobic creatures experience it.
  • The initial process in breaking down glucose to release energy for cellular metabolism is called glycolysis.
  • An energy-consuming phase and an energy-releasing phase make up glycolysis.

As the population size gets
spin [16.1K]

Answer:

As population size approaches the carrying capacity of the environment, the intensity of density-dependent factors increases. For example, competition for resources, predation, and rates of infection increase with population density and can eventually limit population size.

I need help on this question in biology and biology is hard and confusing
Yuliya22 [10]

Answer:

b. the new species must be unable to breed with the original species.

Explanation:

By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.

These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:

  1. Habitat isolation: Two species occupy entirely different and distant habitats.
  2. Temporal isolation: Two species  procreate at different times of the year.
  3. Behavioral isolation: Two species exhibit different mating behaviors.
  4. Gametic isolation: The gametes of the two species cannot fertilize.
  5. Mechanical isolation

Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.
