Biology
1 answer:
PilotLPTM [1.2K]3 years ago
6 0

Answer:

During meiosis 1, the parent cell with double the normal amount of chromosomes, splits into two diploid cells (have enough chromosomes to survive). During meiosis 2, the two diploid cells each split into two haploid cells (have half the amount of chromosomes to survive). Meiosis ends with four haploid cells.

Both Meiosis 1 and 2 have the same phases: Prophase, Metaphase, Anaphase and Telophase. One difference is that Meiosis 1 starts with a diploid cell and Meiosis 2 starts with 2 haploid cells, each with a homologous pair. ... Since there are no homologous pairs (only chromatids), recombination can not occur

Write about how the group of rock layers in record a forme include tilting erosion and folding
neonofarm [45]

Answer:

Most sedimentary rocks are formed in level layers. Therefore, the occurrence of tilted rock layers is evidence of mountain building. ... Tilting can also result when rocks are pushed upward, or uplifted. In some areas of the world, rock layers are so severely tilted that they may be bottom side up. Layered rocks form when particles settle from water or air. Steno's Law of Original Horizontality states that most sediments, when originally formed, were laid down horizontally. ... Rock layers are also called strata (the plural form of the Latin word stratum), and stratigraphy is the science of strata.

I think one must rotate the pt into a supine position and protect her spine.

hammer [34]
Not really. The similar composition is still different from the chemical weathering, making it not really a reproduction
