As the fertility rate increases, the population will increase. That will probably also have an effect on the region by increasing food security. Hope this helps! So it is as population increases, it also increases food security. Have a BLESSED day! :-) :-)

1. If the predictions are true then the population of that region will increase because birth rate increases due to fertility rates.

2. If population increases, food insecurity may occur more because there will be more people to serve food and there is only so much food.

3. The Survivorship curve shows no. of individuals in a certain species that survive to a certain age. the x is time and the y is percentage of organisms surviving. It can also be the group or some other individual basis. So your answer is the first sentence and fourth sentence. The third sentence seemed correct at first, but I have never heard of it comparing life histories of different populations. Still, I would recommend that you check it from your tutorials. The second sentence is wrong because of the "only one" part. It can compare many organisms at a single time. The last sentence is also wrong. The survivorship curve <em>uses</em> the life table or mortality table, but it is not a replacement or another word for it.

What is the distance of what Bob traveled and whats the displacement while bob was traveling.
oee [108]

Distance travelled by Bob was 7 meters and the displacement was 5meters.

<h3><u>Explanation:</u></h3>

Distance is defined as the total length of the path travelled by a body from its initial position to final position. Displacement on the other hand is defined as the length of the straight line joining the initial position and the final position of the body.

Here, Bob travelled from point A to point C via point B which took him to travel more distance. The length of distance from point A to B is 4 meters and from point B to C is 3 meters. So the total distance covered is  4+3 meters = 7 meters.

While the length of path straight from point A to C is 5 meters. So displacement is 5 meters.

The Hershey and Chase experiments involved the preparation of two different types of radioactively labeled phage. Which of the f
Tems11 [23]

Answer:

The correct answer is B.It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment

Explanation:

Hershey and chase in his experiment lebelled the T₂ bacteriophage with radioactive sulfur and radioactive phosphorus separately. Then they infect E.coli with T₂phage and separated phage from bacteria by centrifugation.

Because DNA contains phosphorus not protein, cells infected with phage containing radioactive phosphorous showed radioactivity bacause DNA enters the cell not protein confirming DNA is the genetic material and radioactive sulfur was found in supernatant.

How many amino acids must be obtained in the diet because they cannot be made by the body?
Ivan

Answer:

10

Explanation:

Your body can't produce the ten necessary amino acids and must acquire them from your diet.

The body does not manufacture essential amino acids and must be supplied by food. They don't need to take one meal at a time. The equilibrium is more significant during the day.

The body produces nonessential amino acids from essential amino acids or from the natural degradation of proteins.
