Which of the following represents organisms in a food chain?

Lisa [10]

Answer: c seeds, mice, snakes

Explanation:

a hawks, owls, eagles NO

These animals all eat some form of meat, and they are on the top of all of their food chains. If you put these animals in a room with no food, there'd be no food chain, and they would got out at each other until there was one left, and there'd be no advatanges because 1. they can all fly and 2. they are all top consumers. The same thing goes for D except hyenas can't fly.

b deer, rabbits, cows NO

This is not a food chain because all of the animals are herbivore, so they only eats plants and will not eat each other.

c seeds, mice, snakes YES

The seeds are a producer which is to be eaten by a consumer (the mouse), and which are then eaten by the predator, the snake.

d hyenas, vultures, crows NO

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

Part A: A scientist examines a fruit fly gene involved with the regulation of body development. A section of the DNA sequence fo

Leokris [45]

Answer:

Part A: Thr-Leu-Val

Part B: ACC-UUG-GUU

Explanation:

When you transcribe a DNA sequence to mRNA, you need to remember that in RNA there is no Thymine (T), instead it has Uracil (U). So the base pairings would be like this compared to DNA base pairing:

DNA RNA

A-T A-U

T-A T-A

C-G G-C

G-C C-G

Given the sequence the transcription will be as follows:

DNA : TGG - AAC - CAA

mRNA: ACC - UUG - GUU

Next, to translate it into amino acids, you will use the chart. Now amino acids pair in codons (3 base pairs at a time). Let's take the first codon in your sequence:

ACC

1st 2nd 3rd

A C C

Using the column on the left, find the row that matches it, so in this case A.

At the very top, there is another row of letters, looking at the row of A only, look for the column of the second base which is C.

Lastly, look at the right most column and find the letter that matches the third base within the box where A and C intersect. In this case, C is your third base.

The amino acid where all three intersect is your first amino acid which is Thr.

Just do this for the next codons and you will come up with the answer.
