7 0

The value which is being measured in the columns labeled "Fraction remaining" and "Percentage remaining" is: D. amount of material that has not decayed.

<h3>What is a radioactive decay?</h3>

A radioactive decay can be defined as a radioactive process in which an unstable atomic nucleus undergoes a spontaneous transformation into one or more different atomic nuclei and simultaneously emits radiation, accompanied with a loss of energy.

<h3>The types of radioactive decay.</h3>

In Science, there are three main types of radioactive decay and these include the following:

Alpha decay
Beta decay
Gamma decay

Based on the information provided in the table (see attachment), we can reasonably infer and logically deduce that the value which is being measured in the columns labeled "Fraction remaining" and "Percentage remaining" is the amount of material that has not decayed.

A population of Anolis lizards lives on the mainland. During a storm, three groups of Anolis migrate to three islands, one large

natka813 [3]

Answer:

(i) Small island

(ii) Large island

(iii) Option-3

Explanation:

In the given question, the three population of the Anoles Lizards migrated to three islands of different size.

(i) Genetic drift is a random or by the chance process which changes the frequency of the alleles in the population. The change in the frequency of the allele can be easily observed in the small population therefore the small island with the smallest size of the population will have the strongest genetic drift.

(ii) Heterozygosity of alleles that is with a dominant and a recessive allele is the result of the exchange of alleles in the population. The size of the population is finite on the island therefore the heterozygosity is not introduced in the small population but in a large population, it can be introduced as the mating is random.

(iii) The genetic drift is strongest on the small island therefore L2 allele can be easily influenced by this effect. The selection coefficient is very small that is 0.002 therefore no mutation is occurring on the island.

Both primary and secondary succession begin with pioneer species that

Elina [12.6K]

Answer:

The different zones or region on the planet may some times suffer great distress in creating the best ecologically suitable environment for all the living being, as there are various factors that come in to play such as the soil moisture, presence of humidity and moisture inside the air, and many other factors.Both primary and secondary succession begin with pioneer species that enriches the soil and make it able for the living beings to develop itself in it and provide a suitable environment for life to flourish more frequently.

Explanation:

But, the two steps of successions involves the primary and secondary stage in a given form or procedure. As, the primary succession occurs inside the region which is left abundant due to some reason and there is less for the living being to gain from, so the land then faces the primary succession and many micro organism play a vital role in making the whole situation much better for the living beings.And the lithosphere is highly influenced by the actions of different associations that are formed for the growth of the land mass as a whole.
Now, the secondary succession involves the covering of that specified piece of land by the presence of the specific number of species which would provide more diversity to the land mass and create a better ecological system for the living beings to live inside it.

lianna [129]

Amino acid is to protein as simple sugar is to cellulose.
Amino acids form proteins, the same way simple sugar forms cellulose.
Lipids form fats, it doesn't go the other way round. DNA forms DNA strands, not RNA.

What are 4 phrases describing osmosis

babunello [35]

Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.It may also be used to describe a physical process in which any solvent moves across a semipermeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations.Osmosis can be made to do work.

Osmotic pressure is defined as the external pressure required to be applied so that there is no net movement of solvent across the membrane.
