Provide an environment (bowl or container) filled with 100 of each "prey" type (Consider beans, uncooked pasta, or cotton balls)

. Give yourself a minute to "catch" the "prey" with each "predator" separately (total of 3 minutes). Place each "prey" that is caught into a cup. Count your results after each "predator" simulation.
Which prey was the best adapted? What data do you have to support this?

In what ways does this activity demonstrate the process of natural selection and its consequences?

The activity demonstrated natural selection as the beans will most likely survive since they are better suited to their environment .

<h3>What is natural selection?</h3>

Natural selection is the process which organisms which are better adapted to their environment survive and reproduce while those not adapted die.

In the simulation, the "prey" are beans, uncooked pasta, and cotton balls. The predators are fork, knife, and a spoon.

Using the predators to pick up the prey, the beans were more adapted as they escaped being caught the most, as they had the least number picked up.

Therefore, the beans will most likely survive, demonstrating natural selection which states that organisms better suited to their environment survive the most.

In plants, ______________ are defined as haploid (1n) cells that develop into gametophytes. Gametophytes, in turn, produce eithe
soldi70 [24.7K]

Answer: SPORES are defined as haploid (1n) cells which develops into gametophytes.

Gametophytes inturn produce either haploid (1n) male or females GAMETES that can fuse to form diploid ZYGOTES.

This basically explains what goes on in Meiosis.

Why DNA is absent in blood plasma?
Keith_Richards [23]

Answer:

Red blood cells and blood plasma do not contain DNA. Red blood cells don't have the DNA containing nucleus and mitochondria. Only white blood cells in blood contain DNA. With blood donation, usually most of the white blood cells are filtered out.

Explanation:

because red blood cells don't have the DNA containing nucleus and mitochondria

If 1/8 remains after 21 years, what is the half-life?
vagabundo [1.1K]

Half life formula

The number of unstable nuclei remaining after time t can be determined according to this equation:

N(t) = N(0) * 0.5^(t/T)

where:

N(t) is the remaining quantity of a substance after time t has elapsed.

N(0) is the initial quantity of this substance.

T is the half-life.

It is also possible to determine the remaining quantity of a substance using a few other parameters:

N(t) = N(0) * e^(-t/τ)

N(t) = N(0) * e^(-λt)

τ is the mean lifetime - the average amount of time a nucleus remains intact.

λ is the decay constant (rate of decay).

All three of the parameters characterizing a substance's radioactivity are related in the following way:

T = ln(2)/λ = ln(2)*τ

How to calculate the half life

Determine the initial amount of a substance. For example, N(0) = 2.5 kg.

Determine the final amount of a substance - for instance, N(t) = 2.1 kg.

Measure how long it took for that amount of material to decay. In our experiment, we observed that it took 5 minutes.

Input these values into our half life calculator. It will compute a result for you instantaneously - in this case, the half life is equal to 19.88 minutes.

If you are not certain that our calculator returned the correct result, you can always check it using the half life formula.
