A human liver cell has a different size and shape from a human muscle cell. What is the best explanation for these differences?
A. The cells perform different functions.
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.
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. Organs are made up of numerous cells. Similar cells perform similar functions while dissimilar cells perform dissimilar functions. Therefore, a human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.Learn more at: https://brainly.com/question/22663686?referrer=searchResults

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
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.
This is why the fourth option is the correct one.
What is subduction and what causes it?
Answer:
Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Regions where this process occurs are known as subduction zones.
Explanation:
explain how the oceans serve as a carbon reservoir. what are some of the effects of this on marine life?
Answer:
Carbon pollution is changing the ocean's chemistry, slowing its ability to uptake CO2, making it more acidic, and harming shellfish and other marine life we depend on. The ocean has absorbed about 29 percent of global CO2 emissions since the end of the preindustrial era.Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming.

Answer:
Why is healthy skin important? Healthy skin is important because it is your first line of defense against bacteria and other pollutants in the environment. Healthy skin is more resilient when faced with external stresses, serves as an important sensory organ and helps to regulate our body temperature.
The outermost layer of skin, called the epidermis, produces a thin barrier layer called the stratum corneum. This layer varies throughout the body in its structure, thickness, composition and functional properties. For example, the skin on your palms and soles is thicker than on your face.
Skin changes such as wrinkling are one of the physical alterations most readily associated with aging. It may surprise you that the outer layer of the skin, the stratum corneum, changes very little as we age. The main changes occur at a deeper level. Collagen, a basic chemical building block of skin and connective tissue, decreases with age.

Describe an example of the first law of thermodynamics
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.

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?
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.

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?
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]

Which of the following statements regarding prokaryotic and eukaryotic cells is true
Answer:
I would need the statements to answer that. however prokaryotic cells are plant cells and eukaryotic cells are animal cells
Answer:
They are typically smaller than eukaryotic cells. The DNA of a prokaryotic cell is contained in the nucleoid. There are several ways in which prokaryotic cells are different from eukaryotic cells. Firstly, they are generally smaller in size, their organelles are not membrane bound, and they have no nucleus. They, however, share commonalities with eukaryotic cells including the presence of a bilipid plasma membrane, presence of ribosomes and DNA.
