If u and y are two variables such that
du
= 4v - 3. and u = 5 when v = 2,
du/dv
find u in terms of v.
Answer:
5
Explanation:
The value of u is 5 in term of v by putting the value o v which is 2 in the formula that is du = 4v - 3. Putting the value of v = 2 we get, du = 4(2) - 3. --- du = 8 - 3. ---- du = 5. we are able to solve the question due to the presence of v value. If the v value is not present then we can't find the value of u in term of v. So we can conclude that the value of u in term of v is 5 if we put the value of v in the formula.

Explanation:
At rest the lens of the eye will be more round when the ciliary muscles are contracted true or false
Answer:
True.
Explanation:
Yes, the lens of the eye will be more spherical when the ciliary muscles are contracted due to tension. When the relaxation occurs in the ciliary muscle , the zonular tension is increased, that causes the lens to be flatten and leads to decrease in optical power while on the other hand, when the ciliary muscle contracts, the tension in the equatorial zonular is increased which causes the central lens surface to become more rounded that leads to increases central optical power.

Explain how the lymphatic system is adapted for the transportation of the lymph
Answer:
The lymph capillaries feed into larger lymph vessels. The lymph vessels that receive lymph fluid from many capillaries are called collecting vessels. Semilunar valves work together with smooth muscle contractions and skeletal muscle pressure to slowly push the lymph fluid forward while the valves prevent backflow.

The ability of an ecosystem to support life declines sharply after a population crash
among some of the organisms. A population crash among organisms with which
characteristic could have caused the sharpest decline?
A hibernation during the winter
B mobility on land and in the air
C conversion of sunlight into food energy
D different fur coloring in summer and winter
Answer:
c
Explanation: all other traits are irrelevant and could reply to any part o the food chain, c means that the plats have dropped, meaning that the things that eat the plants wot be able to eat the plants, (primary consumers)and the secondary consumers wont be able to eat the primary consumers,then the tertiary consumers wont be able to eat the secondary consumers. In simpler terms it would cause a chain reaction that would detonate the whole foodchain.

To survive, an organism must be able to maintain stable internal conditions in a changing environment. This process is called homeostasis. The Human Homeostasis Gizmo™ allows you to explore how the human body stays at a nearly constant temperature in different conditions. Notice the Air temp. and Body temp. thermometers representing the air temperature and body temperature.
1. What is the initial air temperature?
2. What is the initial body temperature?
3. Next to each factor listed below, write "increase," "decrease," or "same" based on how you expect that factor to affect body temperature.
A. Raising air temperature: __same____Sweating: __decrease___.
B. Lowering air temperature: ___increase___Shivering: __increase___.
C. Adding clothing: __increase_____Exercising: ___increase_____.
Answer:
1. Initial air temperature: 0 °C (32 °F)
2. Initial body temperature: 37 °C (99 °F)
3. The expected effect of different factors on body temperature are:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Adding clothing: Increase
D. Exercising: Increase
Explanation:
The question is incomplete, it is necessary to look for a software related to this homework.
Homeostasis is a property of organisms that consists in their capacity to maintain a stable internal condition by compensating for changes in their environment through the regulated exchange of matter and energy with the exterior. It is a a dynamic equilibrium controlled by a mechanism of feedback that constitute the self-regulating mechanisms. Examples of homeostasis are temperature regulation and the balance between acidity and alkalinity (pH)
The Human Homeostasis Gizmo™ is a software that allows you to explore how the human body stays at a nearly constant temperature in different conditions. To use it, you have to set the air temperature at 0 °C (32 °F) and the body temperature at 37 °C (99 °F), and click Play. After a simulation of 1 hour, then click Pause and gather the information. Then, do the same cprocedure to test the effect of other factors and Click Reset between each trial. To determine the effect of different factors on body temperature, you have to compare the final body temperature to the final body temperature while there is no specific movement or change.
Then:
1. Initial air temperature: 0 °C (32 °F)
2. Initial body temperature: 37 °C (99 °F)
3. The expected effect of different factors on body temperature are:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Adding clothing: Increase
D. Exercising: Increase
This is for a logical reason, anything you do to heat it or generate heat, will increase the temperature. And anything you do to generate cold, will lower the temperature.
The effect of different factors on body temperature according to Gizmo:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Click Add to a sweatshirt, hat, pants, and parka. Then, adding clothing:
Maintained
D. Set the Exercise level to 70%, then exercising: Increase
When the temperature increases, it is because you are able to record the results from the software and you see temperature goes from 99 °F to 100 °F. When the temperature decreases. it is because it goes from 99 °F to 97 °F. When it is maintained, there is no change.
Three reasons why food self sufficiency Is
important ?
Answer:
FSS has become increasingly important to the political agenda in several countries, especially after the high volatility of food prices between 2007 and 2008 crisis [29-33]. Countries considered self-sufficient at the national level may have a percentage of their population with problems of hunger and malnutrition.
Explanation:
Four scientists observed an area of land that had been cleared of all trees and bushes to make space for a power line. Each scientist had a different argument about the impact clearing this area of land might have on the bird population living in the ecosystem. Which scientist’s argument demonstrates how the ecosystem will MOST LIKELY be impacted?
Answer:
The ecosystem is adversely affected.
Explanation:
The ecosystem is adversely affected due to clearing of all trees and bird population is also adversely affected because these trees are the source of habitat for these birds. When there is large number of birds in an ecosystem so the bird population automatically increases due to the presence of more habitat for the birds so if all the trees are removed so very little population of birds left in that ecosystem and this action leads to great disturbance in the ecosystem.

In a semi-conservative model of DNA replication, which of the following is true?
Answer:
According to the semiconservative model, after one round of replication, every new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA. ... Each subsequent round of replication would then produce double helices with greater amounts of new DNA.
The semiconservative model, after one round of replication, every new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA. Each subsequent round of replication would then produce double helices with greater amounts of new DNA.
Why do they call it semi-conservative?This ]method is known as semi-conservative replication because two copies of the original DNA molecule are made, each copy conserving (replicating) the details from one half of the original DNA molecule.
Each copy has one actual strand and one newly-synthesized strand.
Thus, new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA.

Use the information gathered in the A Three Point Test Cross animation to answer the question. Genes H and K are linked and are known to be 3.5 m.u. apart on the same chromosome. What is the recombination frequency between H and K
Answer:
3.5 percent (3.5%)
Explanation:
In genetics, crossing over or 'recombination' refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis I. The map units (m.u.), also known as centimorgans, represent a measure of genetic linkage between genes/loci located on the same chromosome. One map unit (1 m.u.) is equal to a 1 percent chance that two gene/loci (in this case, genes H and K) will be separated during meiosis by recombination. In the example above, it means that among their progeny, 3.5 percent (3.5%) will be recombinant for the two genes (H and K), and 96.5 percent (96.5%) will have the parental combination of these genes.
