when a prairie dog spots a predator, it responds by giving an alarm call, but only when close relatives are near. this is an example of vocalization.

<h3>What do you mean by predator ?</h3>

The interaction between prey and a predator, where the energy flow occur called as predation and the organism feed on other organism called as predator and the food means the other organism is called as prey.

Predators can be carnivores and omnivores like Lions, tigers, sharks, and snakes, all are predators, it can fall prey to other large animals E.g. a snake is a predator to a mouse, but prey to a hawk.

Carnivorous predators directly kill and eat their prey like large animals such as the lion and tiger, they have their own mode of feeding.

Herbivore are plant eating animals like cows, buffaloes, goats, sheep, and deer; parasites are also under the category of predators which is a host dependent and live, get nutrients from host's body for survival and reproduction.

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.

Select all that apply. Which of the following are not properties of proteins?

Leona [35]

Answer:

The correct answer is C: Derived from oils and the fat of meat

Explanation:

Amino acids are the building blocks of proteins. Each amino acid is composed of a monomer, and these monomers join together to form a complex molecule called polypeptides.

For example, hemoglobin is an oxygen-carrying protein in the red blood cells. It is a globular protein and is made up of two polypeptide sub units. It consists of two alpha and two bets chains.

Proteins are rich energy units and there are different sources of proteins such as beans, pulses, seeds, nuts, milk, and yogurt, etc.

marta [7]

an egg cell has a haploid nucleus so it has half the number of dna because it fuses with a sperm cell to have the full amount of dna.

an egg cell has 23 chromosomes and a sperm cell has 23 chromosomes.

they both have half the amount of dna to form a zygote
