Why does an increase in a species population allow for more variation?

Variation allows some individuals within a population to adapt to the changing environment. Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation.

Which three of the following entities are acellular?.
arsen [322]

Answer:

Prions archea, viroids bacteria, viruses protists are acellular while fungi is cellular.

While viruses have indeed been closely researched for more than a century for infections of people and animals, most viruses, particularly those that infect microorganisms, are still poorly understood. 

Pathogenic RNA molecules are known as viroids. Contagious protein particles are identified as prions. Viruses are larger than that of viroids. Viroids are larger than prions in size.

Molds, wild yeasts, as well as mushrooms are examples of fungi. Numerous fungi are multicellular and also have nuclei in their cells. A protein-encased DNA or RNA core defines viruses being non - cellular organisms. Some scientists disagree with the notion that viruses are living things.

Genrish500 [490]

Answer:

Plants perform photosynthesis and cellular respiration.

Explanation:

  • Cellular respiration is the conversion of glucose into ATP and energy yielding molecules such as NADH and FADH2 along with water and oxygen and carbon dioxide as by-products.
  • Cellular respiration is a process that occurs both in autotrophs and heterotrophs.
  • Only the final stage of cellular respiration i.e. oxidative phosphorylation or electron transport chain requires oxygen as the final electron acceptor.
  • Heterotrophic cells don't take in carbondioxide, they utilize glucose obtained through food.

A period of mass extinction is often followed by ________.
ololo11 [35]
The answer is diversification. The populace segment of an animal varieties' specialty relates to the conveyance of people crosswise over situations inside an area. As developmental clades of species expand, they apparently fill specialty space, and, thus, the rate of increment in species numbers moderates.

identify the subcellular structure of the neuron that forms the basis for the transmission of nerve impulses. (2 points) describ
melisa1 [442]

The subcellular structures of neuron that forms the basis for transmission of nerve impulses are the synaptic vesicles.

What are the steps in impulse transmission between neurons?

  • The action potential or nerve impulse reaches the <u>axon</u> of neuron and depolarises the membrane.
  • Voltage gated Calcium channels open .
  • Arrival of action potential causes the synaptic vesicle to attach to presynaptic membrane.
  • Calcium influx triggers release of neurotransmitter.
  • This neurotransmitters bind to postsynaptic membrane and new impulses are created.

Synaptic vesicle under resting condition:

  1. The neurotransmitter molecules are stored in synaptic vesicles.
  2. If the neurotransmitter leak from the vesicles, they are destroyed by enzymes.
  3. During resting condition, they are placed randomly.
  4. When an impulse reaches the axon, vesicles are arranged in the presynaptic membrane.

Thus from the above we can conclude that, synaptic vesicles are the subcellular structures in transmission of nerve impulses and , under resting condition they are placed randomly.
