A nucleus controls the movement of the cell, if that helps.
The geologist time scale was formed when scientists studied rock layers and index fossils worldwide. With this information, they placed Earth's rocks in order by relative age. Later, radioactive dating helped determine the exact age of the divisons in the geologic time scale.
This scale is organized by the 4.6 billion years of earth's history into sections based on important changes seen in the geologic record. The largest intervals are called eons, with each eon containing many millions of years.
In precambarian time the processes that affect Earth's surface have lessened the erosion on the surface. Earth was being hit by meteorites every second. Now there is water erosion and there wasn't back then. The surface changes have lessened over time.
Answer:
1.2 mL
Explanation:
<em>This is a problem of simple dilution. The dilution principle simply agrees that the number of moles before dilution must be equal to the number of moles after dilution.</em>
Recall that: number of moles = mass/molar mass or molarity x volume.
Hence, for the dilution principle:
initial molarity x initial volume = final molarity x final volume.
In this case, initial molarity of NaOH = 1 M, initial volume = ?, final molarity = 0.1 M, final volume = 12.0 mL.
Initial volume = final molarity x final volume/initial molarity
= 0.1 x 12/1 = 1.2 mL
It thus means that 1.2 mL of 1 M NaOH would be taken and then diluted up to 12.0 mL mark by the addition of distilled water in order to produce 12.0 mL, 0.10 M NaOH solution.
This sums up most of them
The correct answer is option a, that is, multicellular, heterotrophic, and diploid.
Animals refer to the multicellular eukaryotic species, which forms the biological kingdom Animalia. Animals exhibit many features, which distinguish them from other living species. The animals are multicellular and eukaryotic, unlike prokaryotic bacteria, and unlike protists that are eukaryotic but unicellular.
The animals are heterotrophic, not like algae and plants that generate their own food. Almost all the animals make use of some kind of sexual reproduction. They are diploid and generate haploid gametes by the process of meiosis, the larger non-motile gametes are ova and the smaller motile gametes are spermatozoa.
