It’s b chromosomes because the cell nucleus contains the majority of cells genetic material in the form of multiple linear DNA molecules
Technically A and B, but A is more true, so it is the 'correct' answer.
<h2><u>Answer:</u></h2>
Amid the Ordovician Period, the outside of the earth was drastically unique in relation to it is today. About all life on earth was in the seas. The main land life was as exceptionally crude plants extremely close to the water line of the coasts, presumably greeneries and green growth and were of a non-vascular nature.
The Ordovician Period started with a noteworthy eradication called the Cambrian– Ordovician annihilation occasion, about 485.4 Mya (million years prior). It went on for around 42 million years and finished with the Ordovician– Silurian elimination occasions, about 443.8 Mya (ICS, 2004) which cleared out 60% of marine genera.
The timeframe that occurred 488 to 443 million years back. Amid the Ordovician time frame, some portion of the Paleozoic time, a rich assortment of marine life thrived in the tremendous oceans and the primary crude plants started to show up ashore—before the second biggest mass annihilation ever finished the period.
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when organisms from one trophic level are consumed by organisms of the next level. More specifically, 90% of metabolic energy is used, so only 10% will be passed down to the next level.
The experiment is not found here but dependent variables may include the growth rate of moths, whereas the independent variable may be the temperature and the control is water.
<h3>What is a dependent variable?</h3>
A dependent variable is the variable that is being modified by the conditions of the experiment (in the example, the growth is dependent on the temperature).
Moreover, a control variable is any condition that remains constant throughout the experiment (in this case, the amount of supplied water).
In conclusion, dependent variables is the growth rate, whereas the independent variable is the temperature and the control is water.
