Answer:
A. They could contaminate surface and ground water sources.
Explanation:
- Landfills are biodegradable waste sites that contain harmful gases and thus are kept at the periphery of the city. They include greenhouse gases and contribute to global warming.
- These landfills are hazardous places as they contain pollutants that pollute the environment and water, land, and soil.
True. The definition of ecology in easier terms is 'a branch of biology that focuses on how animals and plants relate to problems and stimuli.'
Answer:
The frequency of bb individuals between successive generations <u>wasn't always the same because of natural selection. The capacity of reproduction decreased by a small portion.</u>
Explanation:
Natural selection is the reason why the reproduction of bb generations wasn't always the same. The randomly selection of mates to reproduce was also variable.
Answer:
The risks of various pollution and infections increase with urban sprawl.
Urban sprawl can be described as a condition in which the people from urban area migrate to low residential areas due to which the city starts to expand more in size.
During urban sprawl, more water contamination is likely to be caused as the water available cannot support such a large number of migration. There is not proper sewage system due to which contamination arise and cause sickness in the people. Also, these areas have more pollution due to traffic jam situations which causes sickness.
Answer:
0.035
Explanation:
<u>cv+ is the wild-type dominant allele over cv, therefore:</u>
- cv+cv+ and cv+cv cause wild-type phenotype for crossveinless
- cv cv causes the crossveinless phenotype
<u>Sb is a dominant mutant allele over wild-type Sb+, therefore:</u>
- Sb Sb and Sb Sb+ cause Stubble phenotype
- Sb+ Sb+ causes wild type phenotype for Stubble
<h3><u>Test cross</u></h3>
It's the cross between the heterozygous female with a homozygous recessive male. Remember that cv and Sb+ are the recessive alleles.
X 
-The male produces only 1 type of gamete: cv Sb+
-The female produces 4 types of gametes:
- cv Sb+ ] Parental
- cv+ Sb ] Parental
- cv Sb ] Recombinant
- cv+ Sb+ ] Recombinant
The genes are linked and separated by 7 map units. A distance of 7 mu means that 7% of the resulting gametes will be recombinant. Because there are 2 possible recombinant gametes, each of them will appear in 3.5% of the cases.
The genotypes and proportions of the offspring resulting from the test cross can be seen in the Punnett Square. The phenotypically wild-type individuals will have the genotype cv+ Sb+ / cv Sb+ (heterozygous for crossveinless and homozygous recessive for Stubble) and a 0.035 proportion.
