<h3><u>Answer;</u></h3>
In metaphase I, the chromosome tetrads align on metaphase plate
while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.
<h3><u>Explanation;</u></h3>
- Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes
.
- Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
- During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.
Cells produced when the mutated cell divides.
From your genetics lab, Agrobacterium tumefaciens gram-positive bacterium was used during your experiment on genetic manipulation of a corn plant
Rhizobiaceae is a family of bacteria that includes Agrobacterium tumefaciens. Gram-negative and aerobically growing, these bacteria don't produce endospores. The cells have one to six peritrichous flagella and are rod-shaped and motile. Cells can exist alone or in pairs and range in size from 0.6 to 1.0 m by 1.5 to 3.0 m.
Agrobacterium tumefaciens is a gram-negative bacterium that causes tumors in plants through horizontal gene transfer. In a variety of plant species, Agrobacterium tumefaciens has been widely exploited as the primary agent in the generation of transgenic plants. A soil phytopathogen called Agrobacterium tumefaciens naturally infects plant wound sites and causes the disease known as crown gall by the transfer of (T)-DNA.

The speed of sound wave is slower than electromagnetic wave.
Answer:
Global warming will occur
Explanation:
Greenhouse gases are special gaseous compounds that have this ability to trap HEAT due to their structural composition. They include; carbon dioxide (CO2), chlorofluorocarbons (CFC), methane (CH4) etc.
Anthropogenic activities such as burning of fossil fuels etc. release these gases into the atmosphere where they cause harm to the Earth. Greenhouse gases contribute immensely to the GLOBAL WARMING EFFECT, which is the increase in the temperature of the Earth surface. Therefore, if humans increase the amount of greenhouse gases in the atmosphere via their actions, there will be a GLOBAL WARMING occurrence.
