What are the potential hazards relating to materials handling injuries?
A gene variation that is masked in the presence of dominant alleles.
Answer:
Some genes mask the expression of other genes just as a fully dominant allele masks the expression of its recessive counterpart. A gene that masks the phenotypic effect of another gene is called an epistatic gene; the gene it subordinates is the hypostatic gene.

What species that has been studied in great detail and is used to understand specific phenomena in biology?
Answer:
Species that has been studied in great detail and is used to understand specific phenomena in biology are Model organism .
Explanation:
MODEL ORGANISM - A model organism (often abbreviated to model) is a non-human species that has been extensively studied in order to better understand specific biological processes, in the hope that observations made in the model organism can lead to new understanding of the workings of other organisms. When human experimentation is either impossible or immoral, model organisms are commonly used to study human disease. The shared descent of all living species, as well as the survival of metabolic and developmental processes and genetic material during evolution, make this strategy possible.
Although studying model organisms can be beneficial, caution should be exercised when extrapolating results from one organism to another.
Viruses, as well as model organisms from all three realms of life, are included. Escherichia coli (E. coli) is the most widely studied prokaryotic model organism, having been studied for more than 60 years.
It's a common gram-negative gut bacterium that can be easily and cheaply grown and cultured in a laboratory environment. It is the most commonly used organism in molecular genetics, as well as an important species in biotechnology and microbiology, where it has acted as the host organism for most recombinant DNA research.
Hence , the answer is model organism .

Healthy individuals of Paramecium bursaria contain photosynthetic algal endosymbionts of the genus Chlorella. When within their hosts, the algae are referred to as zoochlorellae. In aquaria with light coming from only one side, P. bursaria gather at the well-lit side, whereas other species of Paramecium gather at the opposite side. The zoochlorellae provide their hosts with glucose and oxygen, and P. bursaria provides its zoochlorellae with protection and motility. P. bursaria can lose its zoochlorellae in two ways: (1) if kept in darkness, the algae will die; and (2) if prey items (mostly bacteria) are absent from its habitat, P. bursaria will digest its zoochlorellae. Theoretically, P. bursaria can obtain zoochlorellae either vertically (via the asexual reproduction of its mother cell) or horizontally (by ingesting free-living Chlorella from its habitat). Consider a P. bursaria cell containing zoochlorellae but whose habitat lacks free-living Chlorella. If this cell subsequently undergoes many generations of asexual reproduction, if all of its daughter cells contain roughly the same number of zoochlorellae as it had originally contained, and if the zoochlorellae are all haploid and identical in appearance, then which statement is accurate?
Answer:
Zoochlorellae also reproduced asexually at a nearly constant rate
Explanation:
Zoochlorellae (singular Zoochlorella), also referred to as Chlorella-like algae, is a genus of algae that live inside freshwater protozoans (e.g., Paramecium bursaria), exhibiting a symbiotic association with their hosts. Asexual reproduction is a type of reproduction that produces new individuals without the fusion of gametes and does not involve a change in the number of chromosomes. In consequence, a haploid parent, i.e., an individual who contains a single set (n) of chromosomes, will produce haploid (n) offspring. Moreover, and since the question indicates that daughter cells contain approximately the same number of zoochlorellae cells as parent cells, it is expected to observe an asexual reproduction rate at a fairly constant rate over time.
Assume that Brown (B) hair is dominant over blond (b) hair and that oval shaped eyes (O) were dominate over round (o) eyes. Complete a Punnett square showing a cross between a mother who was heterozygous for both traits and a father who also was heterozygous for both traits. Based on Mendel’s work what could you predict about this cross? What percent chance do these parents have that the child will be blond with oval shaped eyes? What percent chance do the parents have that the child will have brown hair with oval eyes? What percent chance do the parents have that the child will have blond hair with round eyes?
Answer: 25%
Explanation:
So basically, you draw two Punnett Squares, one for each of the different traits. Since both parents are heterozygous, meaning they have a combination of traits, you would label the four sides of the square B, b, B, and b. Same thing with the eye shape trait. Label the sides O, o, O, and o. Then, you plot it like in the picture I provided. When the B and the B match up, label it BB. When the B and the b match up, label it Bb, etc. Then, since your chances of getting blonde hair (bb) is 1 in 4 (4 combinations total), the percentage of getting blonde hair is 25%. Same thing for getting round eyes, just repeat the process. Now that you have all your squares filled, you can see that your chances of getting both blonde hair and round eyes is 2 in 8, which simplifies to 1 in 4, which is equal to 25%

In pea plants, purple flowers are dominant to white flowers. Suppose two heterozygous purple-flowered plants (Tt) are crossed. What percentage of offspring will also have purple flowers?
Answer:
75%
Explanation:
This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (T) is dominant over the allele for white flowers (t).
According to the question, two heterozygous purple-flowered plants (Tt) are crossed i.e. Tt × Tt. The following gametes will be produced by each parent; T and t. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
TT, Tt, Tt, and tt.
Since purple allele (T) is dominant, offsprings TT, Tt, and Tt will be phenotypically purple-flowered. Hence, ¾ × 100 = 75% of offsprings will have purple flowers.

1. One of the fundamental controls which ecosystems exert over individual species is limits on population size. This is done by a combination of predatory, competitive, parasitic and mutualistic relationships within the ecosystem. Never the less, the human population has increased well beyond what is healthy for those systems. How did we manage to grow beyond these limitations?
2. Natural variations in weather patterns have effects on certain populations. A warm damp spring for example, is ideal for small rodent species and certain insects, who benefit from the lush vegetation produced by this pattern. As a result, their populations swell to high levels. In the end however, this doesn't result in population growth at the higher tropic levels. You don't end up with more predators, just fatter predators. What limits the ability of the higher tropic levels to grow in response to the increased availability of food?
3. An unfortunate series of events finds you stranded on a remote uninhabited south Pacific island, with little chance of being rescued. It is a modest-sized island with adequate resources to support you, if you are careful to minimize your impact on it. You know that inserting yourself into this ecosystem will almost certainly mean the loss of members in some populations, so your goal is to minimize your impact on the overall biodiversity of the system. With this in mind, from which tropic level(s) should you obtain your food?
Answer:
1. Humans are an “invasive species” because human populations have eliminated many ecological relationships, dramatically changing the dynamic of their ecosystems
2. continued loss of energy due to metabolic activities
3. lower trophic levels
Explanation:
1. An invasive species is any organism that is not native to an ecosystem and may negatively alter its new environment. Invasive species don't interact with native species when they are introduced into an ecosystem (for example, invasive species usually don't have any natural predators). Humans are an 'invasive species' that occupy a wide range of habitats and whose presence has caused the extinction of many native plants and animals. Human populations have drastically reduced the biodiversity of different ecosystems by competing with native species for limited resources, and we also have altered their habitats (global human population growth is also due to medicine and farming techniques, reducing hunger and diseases). In this regard, it is important to highlight that the human population can also grow in an ecologically sustainable manner by taking care of the ecosystems we live in.
2. Animals (predators) are consumers, thereby they depend on lower trophic levels for their food supply. The Second Law of Thermodynamics indicates that the continual loss of energy due to metabolic activities at lower trophic levels leads to a decrease in the amount of available energy at higher trophic levels. In consequence, the population size decreases at higher levels due to the amount of energy available from one lower level to the next higher level has to decrease when it is used for metabolic activities (i.e., growth, development, etc).
3. In the food chain, the primary producers are found at the lower trophic level (e.g., plants). Primary producers are followed by consumers (e.g., herbivores), they are followed by secondary consumers (i.e., carnivores that eat herbivores), and so on. When an invasive species at higher trophic levels is introduced into a new ecosystem (in this case, human species), it is imperative to preserve the biodiversity (and consequently also the productivity) at lower trophic levels because they are fundamental for the survival of higher trophic levels (i.e., consumers).
