Answer:
There is inverse relationship between DDT use and bald issue reproduction
Explanation:
Dichlorodiphenyltrichloroethane, is commonly known as DDT, which is a colorless, tasteless, and almost odorless, crystalline chemical, an organochlor. Originally developed as an insecticide, it is famous for its environmental impact. DDT was synthesized first in 1874 by the Austrian chemist Othmar Zeidler. The breeding of bald eagles in northwest Ontario rose from 1.26 offspring per breeding area in 1966 to a low of 0.46 in 1974 and then rose to 1.12 in 1981. The DDE residues in the added eggs showed a significant inverse relationship, confirming the effects of toxin on population-level bald head reproduction and the effectiveness of the DDT ban. The recovery from DDE contamination in the bald eagle appears to be much faster than expected.
Answer:
7 protons, 7 neutrons (READ EXPLANATION)
Explanation:
The atomic number represents how many protons are in an element. Generally speaking, elements have the same number of protons and neutrons. So, an element with the atomic number of 7 will have 7 protons and 7 neutrons.
However it is possible for an element to have a differing number of neutrons (an element will always have the same number of protons because that number is how the element is identified in the first place). Elements that have a number of neutrons that is not the same as the atomic number are called isotopes.
Answer:
1. We can lessen our impact on Earth by using more renewable resources instead of nonrenewable resources. If we were to use these we would stop wasting so much unneeded energy.
Explanation:
According to Food and Drug Administration, safe cooking temperature for chicken is 165 degree Fahrenheit.
There are multiple safe tips provided to cook or barbecue chicken at an outdoor event such as, marinating chicken before barbecuing and refrigerate it for some hours. In some cases, partial cooking before grilling is also safe especially when the partial cooked food go on grill immediate.
On the other hand, meat products other than chicken such as pork, beef, veal and lamb cooks at 145 degree Fahrenheit temperature.
Answer:
In general, lipids are molecules of low water solubility, so they can be classified as low polar. In general, lipids are molecules of low water solubility, so they can be classified as nonpolar.
