Answer:
Cells are made of many complex molecules called macromolecules, which include proteins, nucleic acids (RNA and DNA), carbohydrates, and lipids. The macromolecules are a subset of organic molecules (any carbon-containing liquid, solid, or gas) that are especially important for life. The fundamental component for all of these macromolecules is carbon. The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.

The oxidation of a chemical occurs when
It loses electrons
It gains electrons
It shares electrons
All the above
Answer:
Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction. When oxidation occurs, the oxidation state of the chemical species increases.
Explanation:
oxidation is loss of electrons
here a trick to remember this
oil rig -> oxidation is loss. reduction is gain
Which event is most likely to lead to a heat wave?
A. A high-pressure system lingering over an area
B. A warm, moist air mass moving over a cooler air mass
C. An extremely low-pressure system moving into an area
D. A high-pressure system colliding with a low-pressure system
SUBMIT
Answer:
The correct answer is - A. A high-pressure system lingering over an area.
Explanation:
A heatwave is a period of hot weather that is not normal in the region that can last for two or more days. Heatwaves only take place in case of a temperature increase above the average for a particular area in history.
When air trapped in a particular area due to a high-pressure system. The trapped are leads to an increase in the temperature due to sunlight which leads to the heatwave.
what important role does the magnetic field play for our planet ?
Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds.

Pilots use a simulation to learn to fly a plane. The simulation shows how
adjusting the controls on a plane under different atmospheric conditions
affects the flight. What type of model is this simulation?
O A. A computer model
B. A conceptual model
C. A mathematical model
O D. A physical model
Answer:
The correct answer is - A. A computer model.
Explanation:
Pilots use flight simulations for their training, airlines heavily depend and rely on the training at computer simulators (fixed base simulators). These simulators are based on Artificial intelligence to stimulate real-like virtual conditions with 3D geographical locations and many other components such as cockpit controls and how to use the cockpit displays to control the airplane.
Thus, the correct answer is - A. A computer model.
1.A micelle is a spherical structure compose of a single layer of phospholipids. After looking at the different spherical structures in one of your cups, what type of molecules do you think this type of structures will transport
Answer:
The type of molecule Micelle is likely to transport is Chylomicrons.
Explanation:
Micelles are produced in an aqueous solution, with the polar part facing the micelle's exterior surface and the nonpolar area forming the micelle's core. Both water-soluble and non - polar agents can be delivered via micelles. Because these molecules may enable prolonged and regulated release of macromolecules. In a laboratory experiment, the structure that is likely to be produced after examining different spherical structures is Chylomicrons.
Chylomicrons are tiny lipoprotein globule present in blood and lymph that may be involved in fat breakdown.

2. Give one possible reason why the population decreased in 1990 after it had reached its
carrying capacity
1 I
Answer: The population exceeded its carrying capacity because there were more resources available so many deer reproduced and the population quickly exceeded the carrying capacity.
Explanation:
When the population size exceeds the carrying capacity, the population must decrease. One possible reason is the lack of available resources to support this population size.
What is Carrying Capacity?
A growing population that inhabits a limited space is gradually affected by density, rebounding in the multiplication rate.
The population growth per capita rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
Carrying capacity refers to the maximum point at which the environment can support a growing population.
K is a constant. It coincides with the population size when natality rate and mortality rate are equal to each other. This is the equilibrium point.
If the population size, N, is inferior to K ⇒ the population still grow. When N approximates to K ⇒ the population's growth speed decreases. When N=K ⇒ the population reaches equilibrium, When N is superior to K (N>K) ⇒ the population must decrease in size because there are not enough resources to maintain that size.So when the population size exceeds K, carrying capacity makes the population decrease in size. This is because there are not enough resources for this population to survive.
Probably this population's size exceeded the carrying capacity because there were available resources and animals were not predated by any other species. So this population kept growing until they exceeded the carrying capacity level.
Once they did it, the environment could not support this population size, probably because of the lack of available resources, so the population had to decrease in size. Mortality rate must have increased while natality rate must have decreased.
One possible reason is the lack of available resources to sopport this population size.

Which of the following is a disadvantage of geothermal energy?
A. It is a nonrenewable resource.
B. Collecting it damages the environment.
C. It produces greenhouse gases.
D. It is available near the Earth's surface in relatively few areas.
Answer: D
Explanation: it is “location specific” and is found near the earths crust in few areas
The disadvantage of geothermal energy is that it is available near the Earth's surface in relatively few areas.
What is geothermal energy?'Geo' means Earth and 'thermal' means heat."It is a type of renewable energy (present in the form of heat) taken from the Earth's core."The energy that are inexhaustible or get renewed at very fast pace is called renewable energy.The heat that remains in the interior part of Earth since the time of its formation and radioactive decay of materials is used to generate electricity.It does not damages the environment.It does not emit greenhouse gases. That's why it does not cause climate change.It is available near the Earth's surface and it is location specific i.e., it is located in relatively few areas.Hence, the correct option is: D. It is available near the Earth's surface in relatively few areas.
