Answer:
If a DNA molecule has 30% Adenine the percentage of the other bases is Thymine: 30% Cytosine: 20% Guanine: 20%.
Explanation:
When the percentage that a base has in a DNA molecule is given, the percentage of the other bases can be known using the Chargaff's base pair rule.
A DNA molecule has the information of the genome of a living being, according to a specific sequence of its nitrogenous bases adenine, guanine, cytosine and thymine.
Chargaff was able to establish that in a DNA molecule the ratio of purine : pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, taking into account the complementarity of bases.
Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:
- <em>Adenine 30%.
</em>
- <em>Thymine 30%.
</em>
- <em>Cytosine 20%.
</em>
- <em>Guanine 20%.
</em>
- <em>Total ..... 100%
</em>
In this case, the <u>Chargaff rule is useful to determine the percentage of nitrogenous bases that exist in a DNA molecule, knowing the percentage of a single base</u>.
The answer is (1) decomposer.
(2): Herbivores are animals that consume plants, such as rabbits or deer.
(3): Producers are usually the plants in an ecosystem.
(4): Scavengers are animals that feed off of the remains of other animals already killed by something else (like how a vulture will eat the meat off of dead gazelles after a lion finishes)
(1) decomposer is correct because bacteria and fungi often slowly consume or decompose dead organic material from plants and animals from the ecosystem.
harvesting nuts
Explanation:
The sustainable use of rainforest resources is exemplified by harvesting of nuts.
Wild nuts such as Brazil nut is very important for the sustainability of the Amazon rain forest in South America.
Due to the economic importance of the nut, locals and the government tend to rally round against exploiting rain forests in a negative way.
Families, government, industries e.t.c all depend on the nuts for livelihood. This prevents them from cutting trees in the forest in order to conserve and preserve their nut. Some of the nuts are localized and cannot be grown outside the wild.
This act helps to put the rainforest into a sustainable use.

Answer: A population has a small size high level or genetic drift and very little migration into the population what will most likely happen to the genetic diversity in the population over time?
Explanation: Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.Genetic drift may result in the loss of some alleles Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster
