Since IDK which two you would choose, I'll just list all of them: fish have developed a light, streamlined body to get through water quickly to evade predators with and swim with ease, owls have big eyes so their pupils can get enough light to see in the dark since they're nocturnal, their light bodies and special (Fluffy???) flight feathers let it fly with virtually no sound, allowing it to sneak up on prey, tortoises have a large, hard shell for protection from predators and provides a mobile home on their back! Bats may be practically blind but that doesn't stop them when using echolocation to detect prey and chase it no matter what moves they make or obstacles in the way, snowshoe hares have big feet to sit on top of the snow in the cold winters where they live, their fur also changes colors as the snow melts and the plants start coming back in the more warmer seasons, poison dart frogs, sorry, IDK, cacti have developed spines all over them as self defense, (from what IDK) and they can last a long time without water (I think, don't quote me on that ^^') hope this helps
Answer:
480 nucleotides comprise this molecule of dna
Explanation:
According to Chargaff rule,
- Adenine is paired with thymine
- Cytosine is paired with guanine
Given in the question
Adenine residue = 120
Cytosine residue = 120
So, [A] = [T]
i.e. [A =120] = [T=120]
again, [C] = [G]
i.e. [C=120] = [G=120]
hence, total number of nucleotides present
=> [A] + [T] + [C] + [G]
=> 120 + 120 +120 +120
=> 480.
Answer:
C
Explanation:
essential amino acids cannot be synthesized within the human body . so they have to be taken outside from foods. ( in human)
but non essential amino acids are synthesized in the liver using essential amino acids.
person has to obtain first class proteins such as meat , egg , soya protein in order to get essential amino acids.
but plants synthesize both essential and non essential amino acids within their bodies.
a person needs both essential and nonessential amino acid for his/her function
hope you understood this part :p
