Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).

The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:

-<u>Adenine</u> is paired with <u>Thymine</u> (think of A for apple and T for tree)

-<u>Cytosine</u> is paired with <u>Guanine</u> (think of C for car and G for garage)

emmasim [6.3K]

Answer:

One major side effect of DDT was the extreme damage to bird populations. DDT caused the shells of bird eggs to become extremely thin, which made them prone to breaking from minor disturbances and failing to thrive due to temperature regulation issues. It also slowly poisoned animals, especially birds that fed on insects that were poisoned by DDT. A notable bird species that was affected by DDT is the bald eagle. At one point in the 1960s, bald eagles nearly went extinct due to various effects of DDT. The threat of one of the most recognizable animals in America going extinct led to lawmakers trying to ban DDT.

The phrase "eating like a bird” is often used to express that someone only eats a small amount of food. Explain in detail why th
inn [45]

Answer:

The phrase "eating like a bird” is inaccurate because the eating habits of birds and the amount of food they consume are a function of their size, activity and metabolism, amount of food that would be insufficient for one person.

Explanation:

The phrase "eating like a bird" establishes a comparison between the feeding of a bird and that of a person, referring to the small amount of food that birds consume.

In fact, birds consume food according to the high energy demand of flying, its weight, size, activity and metabolism. A real comparison would establish that birds even eat more than people.

The feeding of each species is different, and the phrase is inaccurate because it only states that a person who eats little food (less than their requirements) is consuming what would really be enough for a bird.
