The respiratory system helps import oxygen into your body and the circulatory system runs that oxygen through out your body which creates carbon dioxide, so the respiratory system takes and exports the carbon dioxide out of your body.

If a tRNA molecule has an anticodon which reads Aug what was the codon of the mRNA molecule
jenyasd209 [6]
The answer is UAC.

In the RNA, base complements are adenine - uracil (A-U) and guanine -cytosine (G-C). So, when in the process of translation, anticodons of tRNA pairs with codons of mRNA, the complementary bases will pair. So, adenine in tRNA will pair uracil in mRNA (A → U), uracil in tRNA will pair adenine in mRNA (U → A), and guanine <span>in tRNA will pair cytosine in mRNA (G </span>→ C):
tRNA:      A U G
mRNA:    U A C

A pea plant purebred to produce round yellow peas is crossed with a plant purebred to produce wrinkled green peas. Round pea sha
krok68 [10]

Answer:

1 out of 16 or 1/16

Explanation:

Let:

R = Round seed      r = wrinkled seed

Y = Yellow seed     y = green seed

Starting from the parent generation or the P generation, the genotype of the parents would be:

RRYY x rryy

This is because the cross is between a parents that are "purebred" for specific traits. This means that the parents are homozygous for the traits which in genotype form is represented by either two capital letters or two lower case letters.

Attached is the F1 generation results between a cross between the P generation.

As you can see the genotype of all the offsprings is RrYy.

Now also below is the cross between the F1 generation offsprings.

For recessive traits, it is only expressed when the dominant gene is not in the genotype, or in other words, the genotype is all in small letters. Since we are looking at two traits, you need to look for how many squares out of the total have all lowercase letters.

There is only 1 rryy out of the 16 predictions. So the answer would be 1/16.

kompoz [17]

Answer:

The organism that can live deep beneath the earth surface despite intense pressure heat lack of water and sunlight might be Nematodes.

Explanation:

  • Nematodes are able to cope extreme heat or extreme cold and dehydration. They have adopted by learning technique that allows them to survive. They can transform into a hardy form called the dauer stage.
  • They can survive harsh conditions for longer durations at this stage. And again awaken themselves when conditions are favourable again.
  • They can be found in hot springs, deserts, high up mountains and in the deepest oceans.
