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.

How would you describe the movement of the sun over 30 minutes?

Answers

Answer:

The Earth rotates from the west to east.  The Sun does not rotate around the Earth, in Thirty minutes. the sun would appear to be in a different part of the sky, and  that is because of the Earth's rotation.

Explanation:

Answer:

The sun is seen in a different part of the sky, but this is due to the rotation of the Earth. The intensity of light and heat changes as the Earth rotates. The speed of the sun changes the angle of the sky in 30 minutes, it is always moving from east to west, so in 30 minutes it will move further west, no matter what time you experiment.

What explains why populations fluctuate around the carrying capacity?

Answers

Answer:

In population ecology: Population fluctuation As stated above, populations rarely grow smoothly up to the carrying capacity and then remain there. Instead, fluctuations in population numbers, abundance, or density from one time step to the next are the norm.

The carrying capacity of an environment is the maximum population size of a biological species that can be sustained in that specific environment, given the food, habitat, water, and other resources available. In population ecology, carrying capacity is defined as the environment's maximal load, which is different from the concept of population equilibrium, which may be far below an environment's carrying capacity. The effect of carrying capacity on population dynamics may be modelled with a logistic function.

The populations fluctuate around its carrying capacity because it is very common even for a stable population to briefly exceed or dip below its carrying capacity.

The size of the population fluctuate due to some environmental factors, presence of predators, competitors etc.

Also reproductive lag time can also cause the population to exceed the carrying capacity temporarily.

What is carrying capacity?

The carrying capacity of an environment is the maximum population size of organisms that can be supported by the ecosystem, given the food, mates, shelters and other resources available.

What is reproductive lag time?

Reproductive lag time is the time required for birth rate to decline and the death rate to increase in response to resource limits.

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.

Answers

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.

Insulin is a hormone that travels through the blood and helps regulate blood sugar levels. Which best describes how insulin travels in the blood?
in the plasma
in the platelets
attached to the white blood cells
attached to the red blood cells

Answers

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.

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

Answers

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
