Meiosis 2 starts with two cells, ends with four.

Meiosis 1 lines up with homologous pairs (Metaphase 1).
Meiosis 2 lines up straight in a line with no pairs (Metaphase 2).

Meiosis 1 one goes from Diploid to Haploid.
Meiosis 2 goes from Diploid to Diploid.

If the earth were not tilted would there be seasons explain? Pls help
krek1111 [17]

Answer:

No

Explanation:

If the earth was tilted, there would be small changes in temperature, but there will be no seasons. The Earth's axis is now inclined at around 24 degrees. This is the main reason for the changing of the seasons. The Northern Hemisphere is in the warm season when the Earth is slanted toward the sun, and the Northern Hemisphere is in the cold season when the Earth is slanted away from the sun. The cycle repeats itself every year because the Earth rotates around the sun at a known and generally constant rate. The sun is higher in the sky during the warm season, making it warmer, and lower in the sky during the cool season, making it colder.

Hope this helps :)

The ________ plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking
Anna11 [10]

The standard plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking a sample from the water blanks to add to empty petri plates which will be filled with melted agar.

The standard plate count is a method used in microbiology, which is used to gain an insight to estimate the density of bacterial population which is present in a bacterial culture broth. This is done by plating a small concentration of the culture in a petri-dish and then counting the colonies which form in the petri-plate. This method is used mostly in the food industry, to find the density of mesophilic bacteria in food. This method is extremely essential to determine the primary source of the bacterial contaminant.

In dna replication, each individual parent strand acts as a _____ strand for the synthesis of a _____ strand.
irina [24]
The answer is template strand; daughter strand.

<span>In DNA replication, each individual parent strand acts as a <u>template</u> strand for the synthesis of a <u>daughter</u> strand. DNA replication is a process of producing of two identical copies of DNA from the original DNA. DNA molecule consists of two strands and each strand serves as a template strand for the synthesis of a daughter cell. DNA polymerase binds to the origins of replication and synthesises daughter strands by adding complementary nucleotides.</span>
