The equation AU = Q - W describes which one of the following?
O A. Second law of thermodynamics
O B. Efficiency of a heat engine
O C. Work done by a gas
O D. First law of thermodynamics
SUBMI
Answer:
D. First law of thermodynamics
Explanation:
The first law of thermodynamics refers that energy can be tranferred or changed form one form to another but it can neither be destroyed nor be created. hence, it is also known as law of conservation of energy.
The equation ΔU = Q − W describes the first law of thermodynamics.
Where
U is the internl energy of the system. ΔU is the change in U. Q refers to the total heat supplied into the system (include both addition and release of energy in the system). W is the net work done by the system.Hence, the correct option is D.
Answer:
Option D, First law of thermodynamics
Explanation:
The first law of thermodynamics states the following -
[tex]dU = Q-W[/tex]
where dU represents the Heat added to the System
Q represents the Change in Internal Energy OR net heat transfer OR sum of all heat transferred into and out of the system
W represents the Work done on the system
The first law of thermodynamics is based on the application of the conservation of energy principle to heat and thermodynamic.
hence, option D is correct

Answer: 1. independent , 2 . dependent
The immunity rate is an independent variable. The number of people affected by the disease is the dependent variable.
What is immune system?
The immune system protects our body from foreign invaders like bacteria, viruses, and fungi, and other toxins.
In general 2 types of the immune system observed in human body.
The innate immune system rapid inheritable response system consist major organs like skin, the eye's cornea, and the mucous membrane that lines the respiratory, gastrointestinal, and genitourinary tracts.
Secondly, the acquired immune system work with the innate system to make a special proteins named antibodies to protect our body from a specific invader.
Human immune system show variation in their production of immune components like cytokines play critical roles and it vary from person to person.
Hence, The immunity rate is an independent variable. The number of people affected by the disease is the dependent variable.

Answer:
B:because plant will make the food,store it,or eat it.usually the plant will stored the food for the winter,because of the soil being frozen and barely any sunlight,it will make it hard for the plant to make more food during photosynthesis,sometimes the plants will die but come back when it is springtime.Once food is made it is used or saved for later use for energy.
Answer:
can be used immediately or stored for later use.
Explanation:
Energy generated through photosynthesis can be used immediately or stored for later use depending on the needs of the plant in its environment.
Sometimes, a plant needs to immediately put this energy into growing new branches or leaves. Other times, such as when a cold winter is approaching, it might be better for the plant to store the energy for later use

In the conifer forest just below the alpine zone of a mountain top, two closely related species of birds that feed on small flying insects have been living together for millions of years. A local naturalist notices that the beak sizes differ on the two birds. The species that eats mosquitoes has a small delicate beak, and the species that eats robber flies (bigger than mosquitoes) has a very large beak. By accident, the naturalist stumbles upon a fossilized bird on the mountain that looks like it could be the ancestor of both species except its beak is neither small nor large, but intermediate in size. What principle could be at work in shaping the beaks of these birds? a. competition b. ecological niche development c. coevolution d. character displacement e. all of the above
Answer: d. character displacement
Explanation:
Character Displacement this is an evolutionary divergence which usually occurs when two similar species inhabit the same environment. This circumstance occurs where differences among similar species whose circulation in an environment overlap geographically are feature in regions where the species co-occur, but tend to be minimized or lost where the species' circulations do not overlap. Which is same case as that of the birds.

in the plasma
in the platelets
attached to the white blood cells
attached to the red blood cells
Answer:
A:in the plasma
Explanation:
Insulin regulates blood sugar levels and it travels in the plasma. Therefore option A is correct.
What is insulin?Insulin is a hormone that is released by β-cells of the pancreas. It controls the amount of glucose in our bodies. It converts glucose into glycogen and then this glycogen is stored in the liver, and whenever the glucose level reduces in the blood, then this stored glycogen is converted into glucose. It also helps in breaking fat and protein for energy.
Insulin is a very important hormone for the regulation of glucose in the blood. A deficiency of insulin occurs when the immune system attacks islets and it causes diabetes, in this disease blood sugar level increases
.
Insulin flows in the blood through plasma. Therefore, option A is correct.

Which of the following statements about oxidative phosphorylation by ATP synthase is FALSE? A) The electrochemical gradient across the inner mitochondrial membrane generated by electron flow is used to synthesize ATP. B) Uncouplers dissipate the electrochemical gradient but electron transport continues without ATP production. C) Inhibitors disrupt electron flow as well as ATP synthesis. D) A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP. E) ATP synthesis occurs via simultaneous conformational changes in protein subunits containing catalytic sites.
Answer
D)A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP
Explanation:
Oxidative phosphorylation reffers to metabolic pathway whereby enzyme is used by the cell to achieve nutrient oxidation, so that chemical energy of molecular oxygen is released as a result of this, adenosine triphosphate (ATP) is manufactured. oxidative phosphorylation is seen in all organisms that are aerobic in nature and it occur in the mitochondria of all eukaryotic organisms. There is electron transfer during oxidative phosphorylation, the electrons moves from the donor to the receptor and this is known as redox reaction, as a result of this energy is released, and this energy is used for formation of ATP.
Therefore,among all the options, A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP is the false statement.

. Your lab technician was to determine the ash content of buttermilk by conventional dry ashing. The technician weighed 5 g of liquid buttermilk into one weighed platinum crucible, immediately put the crucible into the muffle furnace using a pair of all stainless steel tongs, and ashed the sample for 48 h at 800 °C. The crucible was removed from the muffle furnace and set on a rack in the open until it was cool enough to reweigh. (4 marks)
a. What errors were made in the preceding method (there were several)?
b. What were the likely results of these errors?
Answer:
Ashing process is done to evaluate the ash content present in petroleum or other proucts, so that they can be used for certain applications
The two major types of ashing process that includes dry ashing and wet ashing and can be performed using microwave systems or conventional means.
a. errors made in the preceding method while determining the ash content of buttermilk by conventional dry ashing are as following:
Buttermilk should not immediatly put into muffle immediatley, it should be boiled first to avoid splatter.Temperature should be between 500 to 600 degree celcius at high temperature teh ash content can be loss.The sample should be ashed for 12-18 hrs , more than this can damage the required ash content.platinum tip should be used in place of stainless steel because platinum has a lower concomitant tip impedance than stainless stell, so less reactive to ash.The ash should put in dessicator and not allow to kept in open because ash can react with the humidity in teh atmosphere.b. The result that occur due to above errors such as the temperature, time, tongs and leaving ash in open will manipulate the final ash content and its application can be harmful for humans and for other purpose if it will be used.
