<span>A prokaryote is a unicellular organism that belongs to either the domain Bacteria or the domain Archaea. Therefore, unlike a eukaryote, the prokaryote lacks in a nucleus and other organelles. The first organisms that appeared about 3.5 billions years ago were prokaryotes. They developed primitive forms of photosynthesis without oxygen as a waste. The first photosynthesizing prokaryotes appeared about 2.7 billion years ago which led to the changes in Earth atmosphere and consequently organisms dependant on oxygen could arise.</span>
Answer:
100%
Explanation:
Yellow flower color (Y) is dominant over white flower color (y). Plant A is YY while plant B is yy:
YY x yy
Yy Yy Yy Yy
All the offspring would have Yy genotype and since Y is dominant over y, all of them will have yellow flower color as opposed to while.
<em>Hence, the percentage of the offspring that will have a yellow flower would be </em><em>100%.</em>
The type of muscle found at the heart is the cardiac muscle tissue. This tissue has the phyical striped characteristic of a skeletal muscle tissue and works like a involuntary muscle because it works without our control
This type of tissue is packed wirh mitochondria which provides it with alot of energy. This is very crucial becaise the heart has to constantly beat
False
<span>Marine ecosystems like lakes and oceans have aphotic zones. Aphotic zones refer to the zones in the water where there is little or no sunlight. It is found in bodies of water were depths only receive less than 1% of sunlight penetrations. Bioluminescence is essentially the only light found in this zone and most food comes from dead organisms that sink at the bottom of lakes or oceans. </span>
