The work of Thomas Malthus help and influence Darwin Thomas to refine his theory of natural selection by explaining that there is a meaningful competition between the individuals of a particular species or population for a specific resource such as food or shelter.

Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.

Put the steps of DNA Replication in the correct order.
kramer

1. The 2 bases forming each rung of the 'ladder' snap apart. This is caused by an enzyme that passes along the strands, 'unzipping' it

2. Spare nucleotides (in the nucleus of the cell) attach themselves to the 'broken rungs' to repair the break. Each repairing nucleotide is identical to the broken one

A decrease in GFR will cause __________.
lara [203]
<h2>GFR </h2>

Explanation:

A decrease in GFR will cause lower Na and Cl ion concentration in the distal tubule

  • GFR stands for Glomerular Filtration Rate
  • The rate at which kidneys filter blood is called the glomerular filtration rate
  • The main driving force for the filtering process, or outward pressure is the blood pressure as it enters the glomerulus which is counteracted to some extent by inward pressure due to the hydrostatic pressure of the fluid within the urinary space, and the pressure generated by the proteins left in the capillaries that tend to pull water back into the circulatory system (colloidal osmotic pressure)
  • The net filtration pressure is the outward pressure minus the inward pressure
