Answer:
Homologous chromosomes are separated from each other.
Explanation:
In meiosis I during metaphase, all the homologous chromosomes of the cell pair up and get arranged near equatorial plate. Subsequently after completion of meiosis I, these homologous chromosomes get separated from each other so that out of the two cells which are produced after meiosis I could get one chromosome each from the homologous pair. During anaphase I of meiosis I, spindle fibres are formed which drag each of these homologous chromosomes towards two opposite poles. Soon after that, cytokinesis occurs during telophase I of meiosis I leading to the generation of two cells.
For example, humans have 46 chromosomes or 23 pairs of homologous chromosomes. After completion of meiosis I, two cells are produced and each one of them has 23 chromosomes.
Answer:
A
Explanation:
You can replant and gain more crop from seeds. Therefore it is a renewable resource.
Answer:
The foreign gene might be lost
Explanation:
Restriction enzymes have two properties useful in recombinant DNA technology.They cut DNA into fragments of a size suitable for cloning at palindromic sites. Many restriction enzymes make staggered cuts that create single-stranded sticky ends conducive to the formation of recombinant DNA. The foreign might be cleaved and removed from the plasmid. plasmid is an extrachromosomal strand in bacteria.
The most accurate way to measure rainfall is to take a rain bucket of a known diameter (usually 12 or 24 inches) and place it on a scale. The scale subtracts the mass of the container from the mass of the rain.
They’re more accurate because they don’t underestimate the power of intense rain, which can actually affect the accuracy of an analog gauge and they can also measure other forms of precipitation including hail and snow.
Weighing gauges can even be equipped with a device that allows scientists to measure the quantity of chemicals contained in the atmosphere or a particular location through its rainfall. This is especially useful in studying the effects of greenhouse gases on the levels of acid rain.
