Answers

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.

Explanation:

a. lethal phenotype in media lacking adenine supplementation.
b. wild-type phenotype, capable of synthesizing adenine.
c. a weak adenine requirement for survival (intermediate phenotype).
d. a profound defect in adenine synthesis as two enzymes are missing.
e embryonic lethality.

Thanks! If helped give BRAINLIEST ;)

Answer each question, using it as an opportunity to illustrate the depth of your knowledge in this area.
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?

Answers

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).

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?

Answers

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%

Prevention of Foodborne Illness
Food purchased from the grocery store may contain pathogens that cause foodborne illness. To reduce the risk of illness, follow proper procedures for food preparation and storage.
Drag the appropriate items into their respective bins.
1- Divide large pots of soup into smaller batches before cooling.
2- Use a food thermometer to make sure meat has reached an appropriate internal temperature.
3- Thoroughly wash cutting boards used for cutting raw meat before slicing fresh vegetables on them.
4- Do not use color as an indicator of how well-cooked meat is.
5- Wash hands correctly before and after handling food.
6- Refrigerate leftover food within 2 hours.
7- Thaw meat on the bottom shelf of the refrigerator.
8- Wash fresh fruits and vegetables before preparing and/or eating.
Clean Combat Cross-Contamination Cook Chill

Answer:

2- Cook

3- Combat Cross-Contamination

4- Cook

5- Clean

6- Chill

7- Combat Cross-Contamination

8- Clean

Explanation:

A foodborne illness (also known as food poisoning) is an illness caused by eating contaminated foods by harmful microorganisms such as bacteria (e.g., Escherichia coli), viruses, parasites, and/or toxins (e.g., mycotoxins) contained in foods. Some of the most common symptoms of food poisoning include vomiting, nausea and diarrhea. Foodborne illnesses are generally caused by improper practices in the home kitchen, i.e., improper handling, preparation and food storage. Cross-contamination refers to the transfer of harmful microorganisms/toxins from one substance to another. The most common contributing factors to cross-contamination include equipment-to-food contamination, food-to-food contamination, and people-to-food contamination. The most important habit to prevent cross-contamination is washing hands and foods before eating and cooking. Moreover, cooking foods to proper temperatures can destroy microorganisms/toxins that cause foodborne illnesses. Finally, chilling (at 8˚C or below) and freezing (at -18° C) foods can also protect from food-borne illnesses as many harmful microorganisms cannot grow at these temperatures.
