grafted blood vessel come?
What is the ductus arteriosus?
Answer:
the ductus arteriosus is a normal blood vessel that connects two major arteries — the aorta and the pulmonary artery — that carry blood away from the heart. The lungs are not used while a fetus is in the womb because the baby gets oxygen directly from the mother's placenta.planation:

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.

Explain the role of insulin in the homeostatic regulation of blood glucose levels
Answer:
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

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.

What type of plants commonly grows in the lower biomes of a mountain? (1 Punto)
Answer:
Alpines, Mosses, Lichens etc
Explanation:
These type of plants survive in very harsh conditions in which the mountain regions are associated with.
The conditions include a higher degree of temperature, little or no amount of soil particles, dryness and a very low degree of nutrients available to them which makes their growth usually stunted when compared to plants in other regions.

Answer:

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.
Explanation:
Non vascular plants are quite commin in the forests along the coast of Norther California but are relatively rare in the ecosystems around Davis in the Central Valley. What aspects of the life cycle of these plants make it difficult for them to reproduce on our area
Answer:
The Central Valley of northern California is a region where there is little water supply, while nonvascular plants cannot efficiently store water and they have primitive traits that are dependent on water for reproduction.
Explanation:
The Central Valley of northern California is characterized to have little natural precipitation/snowmelt during the dry summer months. In addition, California's climate also has extended periods of drought. On the other hand, non-vascular plants such as mosses and liverworts, are a type of plant that lacks vascular tissues (xylem and phloem), and they also lack true roots, stems, or leaves. These plants cannot efficiently absorb and store water (which fundamental for survival), and thereby the success of these plants in establishing and reproducing in the ecosystems of the Central Valley is limited to their physiological tolerance to desiccation. Moreover, non-vascular plants may also exhibit primitive traits related to their reproductive cycle (e.g., a flagellated sperm) that are dependent on water for reproduction.
