<h3><u>Answer;</u></h3>

D) A sky diver reaches terminal velocity when he stops accelerating.

<h3><u>Explanation;</u></h3>
  • <em><u>Balanced forces are forces that act in opposite directions and are equal in size. </u></em>When an object is acted upon by unbalanced forces then the object stays still or at rest or continues moving at a constant velocity in the same direction.
  • Unbalanced forces cause an object or a body to change its motion or velocity and direction.
  • <u><em>A sky diver who reaches terminal velocity when he stops accelerating, experiences balanced forces. Terminal velocity being a point at which the drag force is equal to the force of gravity.</em></u>

How does the genotype of a bacterium determine its phenotype? Use the terms gene, mRNA, ribosome, and polypeptide in your answer
tensa zangetsu [6.8K]
Typically, the genotype is encoded in the DNA by the gene; this gene in the DNA will then undergo the process of transcription and the information in the gene will be transcripted into mRNA. The mRNA will then undergo the process of translation and the information in the mRNA will  be translated into a polypeptide chiefly by the action of ribosome. Thus, bacteria with different genotypes will have different protein which automatically means that they will have different phenotypes.

The Hubble constant measures distance in?
PIT_PIT [208]

GIVE ME BRAINLIEST PLS LOL    

The value of the Hubble constant is estimated by measuring the redshift of distant galaxies and then determining the distances to the same galaxies (by some other method than Hubble's law). Uncertainties in the physical assumptions used to determine these distances have caused varying estimates of the Hubble constant.

Which statement best describes an effect of the low density of frozen water in a lake and why ?
Black_prince [1.1K]

Answer:<u><em>When water freezes, it contracts, decreasing the water level in a lake. Water in a lake freezes from the bottom up, killing most aquatic organisms. When water in a lake freezes, it floats, providing insulation for organisms below.</em></u>
