The electromagnetic spectrum shows the parts of light orchestrated by their wavelengths. The range for the most part comprises of both visible as well as invisible light. Together, they are called electromagnetic radiation. They are electromagnetic in light of the fact that they comprise of both an electric field and an magnetic field, and these fields travel in wave and travel at the speed of light: 3.00 × \bold{10^8} m/s.

Gene mapping for beak color and feather length in biology what is this
just olya [345]
I am not entirely sure about this. So maybe my response can help you find the answer a little better if my answer is not entirely right?

These last three questions are referring to everything you just worked on. So all you would have to do is refer back to your previous answers. Recall that the titles of the "part 1, 2, and 3" are titled "crossing beak color and tail-feather length", "crossing beak color and feather color", and "mapping tail-feather length and feather color".

1.List the distances between each pair of genes:
beak color and tail-feather length: 20 MU
beak color and feather color: 16 MU
tail-feather length and feather color: 4 MU

2.Which two alleles are the farthest apart?
(the one that is 20 MU apart) Y and L

3.Which two alleles are the closest together?
(the ones that are 4 MU apart) L and B

Land that used to be a meadow is converted to a housing development. the next year, fewer milkweed flowers are observed. what ha
adelina 88 [10]

A former meadow is turned into a housing complex, and the next year, fewer milkweed blooms are seen due to pollination.

What applications does milkweed have?

The herb has also been used medicinally despite the danger of poisoning. Many native cultures chewed the roots of milkweed to heal diarrhea and used the sap to remove warts. Infusions and salves were also made from it to treat asthma, coughing, fevers, rashes, and swelling.

What kind of soil is ideal for milkweed growth?

In regions with more rainfall, like the eastern United States, milkweed thrives. Asclepias tuberosa, sometimes known as butterfly weed, thrives in drier climates like those in the western United States. Sand or gravelly soils are required. The Clay variety is an anomaly since it thrives on heavier soils, especially dry clay. Plant under the intense sun.
