answer : = 1.25
Explanation:
i) Determine the rate of mtDNA percent divergence
From the data given the most closely related specie is Chimpanzee ( 8.8 sequence difference )
Note : Given that this divergence took place seven million years from now
∴The rate of mtDNA percent divergence per 1 millions years
= 8.8 / 7 = 1.25
Answer:
In uranium-lead dating, for instance, the radioactive decay of uranium into lead proceeds at a reliable rate. Based on the very old zircon rock from Australia we know that the Earth is at least 4.374 billion years old.
And that's how after rounding we know that earth is 4.5 years old.
Answer: the Pistil (also called the Carpel). This is made up of the Stigma, the Style and the Ovary. The ovary contains the ovule (or ovules) where fertilization occurs. The Stigma is where the pollen lands.
Explanation:
Waste from fish-feed and faeces can pollute the water and seabed around intensive fish farms leading to poor water and sediment quality
At the top of the body of a water, there is a lot of light from the sun, which also means a lot of solar energy. This allows for a fruitful photosynthesis.
In contrast, at the bottom of the water, there isn't as much, or sometimes any, sun light. Because of this the organisms at the bottom of the body of water
<span>D. must rely on other means than photosynthesis
