The correct answer is absence of jaws.
Lampreys and hagfish are in the class Agnatha, they are jaw-less fish. The members of the agantha class are probably the earliest vertebrates. Scientists have found fossils of agnathan species from the late Cambrian period that occurred 500 million years ago.
Well, wind and solar energy are good places to look at. The highest wind speed recorded in Antartica was roughly 199 mph, so they would definitely gain a large amount of energy from the wind. A smaller turbine can handle severe weather conditions, so setting some up along the most wind ridden places would be good. Solar energy would also be the best option since their days are longer than their nights over there. There can be days at a time where the sun doesn't rise at all, and then there are some where there is sunlight for a full 24 hours. So, it really depends on your preference, and the cons and pros of the energy type.
For wind: Set up a series of turbines along the areas that have the most wind. Turbines can withstand large storms. There is usually some kind of wind blowing.
For solar: Set up some solar panels where they would be able to get the most amount of sunlight. There are 24 hour long days of sunlight, but there are also some days where there is no sunlight at all.
Hope this helps you a bit.
its either The division cycle of most eukaryotic cells is divided into four discrete phases: M, G1, S, and G2. M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs or In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important. hope this helped!!
Answer:
Desertification is the destruction of the biological potential of the land and it is generally viewed as an advanced stage of land degradation. human activities also cause the process such as poor irrigation practices, deforestation, the expansion and intensive use of agricultural lands, and overgrazing.
Such human activities put enormous pressure on the land by altering its soil chemistry and hydrology. Modern agriculture causing a negative impact on the soil and land by overexploiting the biological and chemical potential of the land.
Answer:
0.01645 KM
Explanation:
1000 M = 1 KM
16.45 / 1000 = 0.01645
