Answer: c,d,e
Explanation:
I did this and this is correct
Answer:
The following Statements accurately portrays role of natural selection in antibiotic resistance
c) some bacteria possess a gene for bacterial resistance. these bacteria are likely to survive a course or antibiotics and reproduce.
d) bacteria containing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce
e) when someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. the bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce
Explanation:
When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features to succeeding generations.
As in option C , bacteria possessing better gene will b selected by the nature and hence portrays Natural selection
In option d Bacteria reproduce by plasmid (extra chromosomal DNA ) transfer . Bacteria with antibiotic resistant gene with pass these genes to the succeeding generations.
When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving bacteria possessing gene resistant against antibiotics. Here, Darwin’s theory of natural selection comes in. This gives the bacteria an advantage over other(which do not possess antibiotic resistant gene) this bacteria will grow better than its neighbors and can increase in numbers
In option e When one quits antibiotics before completing the entire course of any prescribed antibiotic. The antibiotic resistant bacteria survives. Bacteria that are not controlled or killed by antibiotics. They are able to survive and even multiply in the presence of an antibiotic.

Which of the following would be an example of positive feedback? thanks!
Select one:
Shivering by the muscles when temperature drops.
The attraction of platelets when a wound occurs.
Sweating due to an increase in body temperature.
The reduction of hormone production during pregnancy.
Answer:
2
Explanation:
The attraction of platelets when a wound occurs indicates a positive feedback. The correct option is B.
What is feedback mechanism?The feedback mechanism is the body's mechanism for keeping hormone levels within desired limits.
The feedback mechanism is activated by an increase or decrease in hormone levels. The body has two types of feedback mechanisms: positive feedback mechanisms and negative feedback mechanisms.
Positive feedback loops and negative feedback loops are the two types of feedback loops.
Positive feedback increases system output, causing growth or decline. Negative feedback dampens output and helps to keep the system stable around an equilibrium point.
Platelet plug formation is thought to be a positive feedback process because ADP and VWF levels rise as more platelets activate to form the plug.
Thus, the correct option is B.

What does the data reveal about the relationship(s) between the impactor's mass and crater depth?
Answer:
For each ball, the crater diameter increased as the height of the ball drop increased. My conclusion is that crater diameter increases with increasing mass. Also as the height of the ball increases, so does the crater diameter. Thus crater diameter is proportional to the mass and velocity of the impactor.

Do you think there should be government regulation against known carcinogens? Why or why not? Write a 5-6 sentence paragraph that states your opinion and explains the reasons for it.
Answer:
Yes,there should be government regulation against known carcinogens;
Because of following reason;
food containing carcinogens cause food poison,cancer and effect our health negatively.it degrades the immunity power of us which makes us weak.if regulations is made people be awared and stop consuming those type of food.people start to consume good diet.Answer:
Yes. I believe that there should be government regulation against known carcinogens. Take food into consideration. Before President Roosevelt passed the first Food and Drug Act, mothers would quite literally feed their children formula that could have heroin in it or any unregulated substance, because companies could do so without any repercussions. Meat factories were dangerous and its no secret that there were a significant amount of rats that fell into the meat. After this act was passed in the United States, factories cleaned up their conditions and food became somewhat safe to eat. This act protected the consumer and made them aware of what they were literally consuming. Why is this different from government regulation against carcinogens? Did you know that bug spray can contain carcinogens? Old fridges? Granite countertops? Weedkiller? Because I did not. Consumers should be aware of the contents of the things they are buying. Corporations SHOULD be held responsible for putting customers in harms way. Government legislation should be passed to protect those who do not know better. Because we should not have to know better. We should already know.

The Pine Tree shown below is a common gymnosperm. Name three adaptations this tree has that allow it to live on land
A waxy cuticle that covers the outer surface of the plant and prevents drying out through evaporation. The cuticle also partially protects against radiation damage from UV light.
Stomata (singular: stoma) are present in all land plant lineages except liverworts (similar to -but not the same as! – mosses). Stomata are pores or holes which allow for exchange of gasses (such as oxygen and carbon dioxide) between the plant cells and the environment. Stomata or similar structures are necessary in land plants because the waxy cuticle blocks free-flow of gasses.
Roots (or root-like structures) anchor plants to the soil and—in plants with true roots— serve as conduits for water absorption. All land plants except Bryophytes (mosses, liverworts, and hornworts) have true roots. Bryophytes have root-like structures called rhizoids that anchor them to their substrate but are not involved in water absorption (which is less important for Bryophytes because they can only survive in very moist environments).
Mutualistic association with mycorrhizal fungi, which are tightly associated with plant roots. Mychorrhizal fungi are associated with approximately 80% of all land plant species and provide additional surface area for absorption of both water and nutrients from the soil. The fungi share these resources with the plant roots, and—in exchange— the plant shares photosynthetic sugar products with the fungi.
The alternation of generations life cycle, which includes both a multicellular haploid stage and a multicellular diploid stage. Why is this an adaptation to life on land? It isn’t, in and of itself—in fact, it also occurs in *some* green algae, which are aquatic but share a common ancestor with all land plants. But specific adaptations to the alternation of generations life cycle have occurred in different lineages of plants, and those adaptations DO function as adaptations to life on land. We’ll consider these adaptations later in this reading.
These are from my text book, from last year.
Answer:
It has cuticle, a waxy, airtight seal that covers plants and allows them to retain water.
It has seeds, plant embryos without a protective cover on the scales of a cone which allows them to disperse into new locations.
It has pollen, but it is not produced in flowers, which allows it to reproduce without the need of water.
