Answer:
<em>The overuse of pesticides</em>
Explanation:
Pesticides are usually sprayed on plants so that the pest organisms can be killed. But these chemicals sprayed on plants can be toxic for humans when humans consume crops which have been sprayed with pesticides. Also, erosion causes these toxic chemicals to get eroded in the nearby lakes. The chemicals in the pesticides are harmful for every life that uses this water. Hence, the overuse of pesticides might kill pests but it is also toxic for consumption by humans.
If scientists believe that the newly discovered gene has two alleles A and a and that the alleles show incomplete dominance, the best way to prove this is to look for subjects who are homozygous with respect to the different alleles. The offsprings will all have the genotype of Aa and if indeed, the alleles show incomplete the dominance, the traits of the first generation will not manifest completely but a mixture of two will.
The three liquids will form three layers, the bottom layer is more dense and the top layer is less dense
The correct sentences are the following:
A) Antibiotic resistance in bacterial populations is caused by natural selection of bacteria that inherit mutations that make them resistant to the antibiotics.
C) Crossing-over causes a shuffling of allele combinations during meiosis as the alleles from each parent form new combinations on homologous chromosomes.
E) When two bacteria are linked during conjugation, the donor cell passes DNA to the recipient cell which causes genetic recombination.
Explanation:
These three options are associated with the generation and preservation of genetic diversity
Answer:There are four types of complex carbon-based molecules in all living organisms: proteins, carbohydrates, lipids, and nucleic acids
Explanation:Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function
