Which of the following best shows the process of evolution?
O A lizard's color becomes brown as it sits on a log
O A bear goes into hibernation
O A plant loses its leaves in a drought
O A population of mosquitoes develops resistance to a pesticide
Answers
Answer:
A population of mosquitoes develops resistance to a pesticide
Explanation:
Evolution can be defined as the way the characteristics of a species change over several generations. This process relies on natural selection - a mechanism in which individuals that are better adapted to their environment survive and reproduce most successfully.
A population of mosquitoes developing resistance to a pesticide is an example of adaptation. This is how mosquitoes become adapted to their environment and increase their chances of survival. Eventually, most of the mosquitoes will be resistant thanks to natural selection. This is how mosquitoes evolve.

As you walk to physics class, you start out at a speed of 2 m/s, for a time of 120 seconds (you’re really excited to get to class). Then you see your friend and slow down to a speed of 0.5m/s for 30 seconds. You stop at your locker for 40 seconds (a speed of 0 m/s). You realize that you are about to be late so you hurry to class at a speed of 1 m/s and get to class just as the bell rings (4 minutes after your trip started). How far did you travel total?
Answers
Answer:
The total travelled distance is [tex]51065 \mathrm{~m}[/tex]
Explanation:
• Speed, time and distance is one of the most common and important topics in the Mathematics or Quant section.
• Calculate total speed;
[tex]\therefore \text { Total Speed }=2+0.5+0.0+1=3.5 \mathrm{~m} / \mathrm{sec}[/tex]
• Calculate total time taken;
[tex]\therefore \text { Total time taken }=120+30+40+14400=14590 \mathrm{sec}[/tex]
• To find total travelled distance, use the formula
[tex]\text { Distance }=\text { Speed } \times \text { Time }[/tex]
[tex]\mathrm{d} &=3.5 \times 14590 \\[/tex]
[tex]&=51065 \mathrm{~m}[/tex]

OB. One of the cells is used to reproduce more cells while the other is not.
OC. One type of cell develops into the other type of cell.
OD. One of the cells must have come from another species.
Answers
Answer:
A
Explanation:
A human liver cell would have a different size and shape from a human muscle cell because they perform different functions in the body.
The shape a cell would assume and its size depends on the function the cell performs. The functions of the liver in the body of humans differ greatly from the functions of muscles. While the former helps in detoxification, deamination, digestion, etc., the latter helps in support, movement, etc.
The correct option is A.
A human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.
CELL:
Cell is the basic and fundamental unit of life. It is the simplest level of organization of an organism. Cells contain organelles that help them perform specific functions.

For a neuron with an initial membrane potential at -70 mV, an increase in the movement of potassium ions out of that neuron's cytoplasm would result in the
Answers
The potassium ions are positively charged(cations) if the charge is -70mV the outflow of cations will cause a decrease in the potential. The potential will become lower than -70mV.
The given condition of an increase in the movement of potassium ions out of that neuron's cytoplasm would result in the hyperpolarization of the neuron.
Hyperpolarization is a change in a cell's membrane potential becomes more negative at a particular spot on the neuron's membrane
A hyperpolarization is an event or stage that takes place when some potassium channels remain open and sodium channels reset.The sodium-potassium pump keeps the concentrations of Na+ and K+ at constant disequilibrium to set the membrane potential of neurons.Increased potassium movement leads to more potassium ions out of that neuron's cytoplasm. It can be seen as a slight dip following the spike.Thus, the correct answer would be the hyperpolarization of the neuron.

Set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks. Each set was watered daily with 50 mL of a 0.1% fertilizer solution. Which statement best explains why the green plants died and the mushrooms survived?
Answers
Answer:
This question lacks options, however, it can be answered based on general understanding.
The green plant died because of absence of LIGHT
Explanation:
Plants (green) are autotrophic organisms i.e. organisms that are capable of synthesizing their own food via a process called PHOTOSYNTHESIS. However, on the other hand, mushrooms (kingdom FUNGI) are heterotrophic organisms i.e. rely on other organisms for energy source and cannot make their own food.
Green plants strictly require light energy from the sun in order to perform the process of photosynthesis. According to this question, a set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks and watered daily with 50 mL of a 0.1% fertilizer solution. The green plants, despite the nutrients and regular watering dies because they were not exposed to LIGHT in order to make their food via photosynthesis. However, since light is not a requirement for mushrooms to obtain food, they will surely survive.
Describe an example of the first law of thermodynamics
Answers
Answer: According to the first law of thermodynamics, energy can be transferred from place to place or changed between different forms, but it cannot be created or destroyed. For instance, light bulbs transform electrical energy into light energy, and gas stoves transform chemical energy from natural gas into heat energy.
Explanation:
Answer: The first law of thermodynamics states that: energy can neither be destroyed or created, it can only change forms. An example of this in an ecosystem would be when a plant absorbs the sun's energy and photosynthesizes, storing the energy as glucose.
