A science class tested ways to clean water after an oil spill. Each group of students was given 100 mL of vegetable oil, 100 mL

of engine oil, and 800 mL of water in a rectangular plastic container. Each container also held five floating wooden cubes (5 cubic centimeters each) representing animals in the water. Each group was tasked with removing as much oil as possible in a 20 minute period, leaving “clean water” in the container, using whatever tools they brought to class. The results of the “clean-up” are presented in the table below.

Tall pea plants are dominant, while short plants are recessive. In a cross between a purebred tall plant and a purebred short pl
zloy xaker [14]

Answer:

1. tall (or heterozygous)

2. 3:1

3. carriers

4. Each parent organism contributes one copy of its alleles in a seemingly random fashion to its offspring, as meiosis to create gametes (egg or sperm cells) reduces the number of genes by half. Therefore, each gamete contributes only one allele.

5. A Punnett square is a diagram used to map out the possible genotypes of a child given the genotypes of its parents. In a Punnett square, the genotype of one parent is listed in the first row of the square, and the genotype of the second parent is listed in the first column. Then, in the middle squares, all possible genotypes of their offspring are listed, and the phenotypes are calculated using the law of dominance.

6. Purebred strains of organisms always produce heterozygous offspring in the first generation, with all members of the first generation exhibiting the dominant trait for the gene of interest. The second generation typically has a 3:1 mix of dominant and recessive phenotypes, respectively.

7. Punnett squares predict that the second generation of two distinct purebred homozygotes for a trait will have a 3:1 ratio of dominant to recessive traits. Mendel did careful statistical analysis on his hybridization experiments and found that, for each of his seven characteristics of interest, the ratio was approximately, but not exactly, 3:1. Therefore, Mendel's experimental observations match the predictions of Punnett squares quite well.

1. What is one way that kinetic energy might be involved in rescue team missions?
tiny-mole [99]
1. Kinetic Energy is the energy of mass in motion. In a rescue mission, kinetic energy is the most used energy to carry out the rescue operation successfully.Anything that moves and has a role in rescuing the victims can be termed as the kinetic energy involved in rescue team missions

2. You may be saving someone from a rock slide, where the rocks will fall at any time, before they fall they have potential energy.

If natural selection has no foresight, how can it explain features that seem to prepare organisms for future events? for example
Nezavi [6.7K]

The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.

Salamanders, ospreys, snapping turtles, and beavers all live in aquatic habitats. Salamanders lay their eggs in small freshwater
AveGali [126]

Answer:

A. Salamanders

Explanation:

Specialists species are species that can thrive in a unique and limited range of resources. They require a specific environmental condition to reproduce and survive in  environment and also have limited or few diets they need for nutrition. These limiting characteristics put them at a disadvantage of being endangered and threatened.  

Salamanders are endangered species that are fast going into extinction. They require wetland (freshwater pools) for reproduction to be possible, and feed mainly on insects. This makes them specialist species.

Ospreys, snapping turtles, and beavers are all generalist species. They can all thrive in a wide range of environmental conditions, and also have varieties of diets they can get nutrition from to survive.

When evacuating victims and endangered personnel in a severe emergency in relation to the support zone where should routes be di
Lorico [155]
When evacuating victims and personnel currently facing danger to their lives, an establishment should have a safe evacuation routes. The evacuation route should be placed in the Exclusion Zone which means that it is a large site with obstructions and not safe until the safety area is reached. Another would be developing the Contamination Reduction Zone which is designed for individuals that are facing chemical dangers. Decontamination while inside the building is inadvised but would be applied in the arrival to the said zone. An access to potential routes should be available. Obstructions like locks, blocked doors are inadvisable. Routes should be free from items that are not needed within the area. Also, multiple routes that are separated from each other is recommended for evacuating numerous amount of people at the same time or when fire blocks one, there would be another choice available.
