Which option identifies ways that people positively affect Earths resources

Biology
1 answer:
matrenka [14]4 years ago
6 0

Answer:

Halting the use of resources is impractical. Increasing the mining efforts would lead to further depletion of resources. Hence, the correct options are: build dams, use cars that emit fewer harmful gases, and halt the runoff of factory waste into rivers and streams which would positively affect Earth's resources.

kirza4 [7]

The statement: Allele frequencies will stay the same, but genotype frequencies will change over time is False, option B

<h3>What are dominant and recessive traits?</h3>

Dominant traits are traits which whenever the allele for such traits appear will always be expressed in the offspring.

Recessive traits are traits which are masked by the dominant trait whenever the allele for the dominant traits appear. Recessive traits are only expressed in the absence of the dominant traits.

In the snail population, the M is dominant over m and that selection acts against hom0zygous recessive individuals.

Also individuals in the population will only mate with others of the same genotype.

Overtime, it will be observed that the allele frequencies and the genotype frequencies will change over time.

In conclusion, the allele frequency and genotype frequencies of the snail population will change over time.

Note that the complete question is given below:

You are working with a population of snails. during the mating season, you observe that individuals in the population will only mate with others of the same genotype (for example, mm individuals will only mate with mm individuals). there are only two alleles at this locus (M is dominant; m is recessive); you have determined that the frequency of the M allele = 0.4 and that selection acts against h0m0zygous recessive individuals. Consider whatbwill occur in this population overbthe course of many generations and mark A for True or B for False for each of the following statements:

Allele frequencies will stay the same, but genotype frequencies will change over time.

Which base is normally used in the synthesis of RNA but not in the synthesis of DNA
Veronika [31]

Answer:

Uracil

Explanation:

Like DNA, RNA is made up of nucleotides called ribonucleotides. However, unlike DNA, RNA contains the sugar ribose instead of deoxyribose and the base uracil instead of thymine. RNA also contains of only one polynucleotide chain. Uracil is a type of nitrogenous base that is replaced by thymine during the formation of RNA.
