Why do mitochondria and chloroplasts have dna in them?
Lelechka [254]

Answer:

DNA replication and transmission to daughter organelles produces cytoplasmic inheritance of characters associated with primary events in photosynthesis and respiration. The prokaryotic ancestors of chloroplasts and mitochondria were endosymbionts whose genes became copied to the genomes of their cellular hosts.

umka2103 [35]

Answer:

Anomalous expansion

Explanation:

Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.

At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.

When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.

This way, organisms can survive in the water due to the lower layer not freezing.

USPshnik [31]
(1) wave frequency is the number of waves passing a point at a certain time. Usually, this is expressed in a unit of 1/s or Hz. 
                f = (600 waves) / (8 hours x 3600 seconds/1 hour) = 1/48 or 0.02 Hz
(2) wave period, T = 1/f 
                                   T = 1/48 Hz = 48 s
(3) wave speed
                               speed = (600 waves)(3 ft/1 wave) / 8 hours 
                                                 = 225 ft/h

"explain the process of transcription including the three major steps of initiation, elongation, and termination."
4vir4ik [10]
<span>Initiation is when the RNA polymerase separates the strands of DNA at the site of the promoter and connects the RNA nucleotides while they base pair with the DNA template. Elongation is when the polymerase moves downward undoing the DNA and stretching the RNA transcript to the 3 prime end. As this occurs the strand begins to form a double helix. Termination is when the RNA transcript is released and the polymerase disconnects from the DNA.</span>
