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

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
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.

(A) conservation and afforestation
(B) preservation and conservation
(C) restoration and preservation
(D) reafforestation and restoration
Answer:
(D) Reafforestation and restoration
Explanation:
Replanting trees in helping to "re-forest" the hill and restore it to how it was before.
Replanting trees in a place where trees used to exist is an example of reafforestation and restoration.
Afforestation means to create a forest (trees) where they do not exist before.Reafforestation, on the other hand, means to create a forest (by planting trees) to an area that used to be a forest but has been removed due to one reason or another. Similarly, restoration means restoring an area to what it used to be. Forest restoration is the practice of restoring a forest that has been modified by natural or anthropogenic processes to its old self.Thus, replanting trees on a bare hillside is an example of reafforestation and restoration.

explain the process (reflex action) that happens when you pull your arm away from an open flame. use steps to explain your answer. identify the receptor in the skin, the stimulus, the neurons,the effector(muscle) and the body's response to the stimulus.
Answer:
A reflex action is defined as an involuntary action of body in response to a stimulus, which protects the body from any harmful conditions including touching open flame.
A reflex action follows a sequence of action that helps in involuntary action, tha include the stimulus, receptor in the skin, the neurons (sensory, relay and motor neurons), the effector(muscle) and resposne of body to stimulus.
In the reflex action when a person pull his/her arm away from an open flame, the stimulus will be the hot flame that send a signal to the nervous system.
The sensory receptor found in the dermis or epidermis of skin called cutaneous receptors, senses the temperature change.
Then the sensory neuron comes in action which sends electrical impulses to a relay neuron (located in spinal cord) and relay neuron sends impulse to motor neuron.
Motor neuron sends that electrical impulses to a muscle which act as an effector which allows muscle to contracts to move hand away.
So, at the end the body resposnes to move hand aways from the open flame.

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.

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
