Which of the following is not a abiotic factor ?
A. Dirt
B. Sunlight
C. Water
D. Air
Answer:
A) Dirt
Explanation:
Our environment comprises of two factors namely biotic factors and abiotic factors. Biotic factors are those in an ecosystem that consists of all living organisms such as plants, trees, humans, insects, animals, birds, etc. These living organisms will interact with each other and sustain their life.
Abiotic factors are those that contain non-living organisms. These factors include soil, air, water, sunlight, etc. These factors often have a greater impact on biotic factors. From the question, a plant is a living thing and it belongs to the biotic factor.
Answer: They are all Abiotic factors actually but my best guess would be B. sunlight

How is the small intestine designed to absorb digested food ?
Answer:
Small intestine is designed to more and more area for absorption of digested food and transfer into the blood for circulation throughout the body. The inner lining of small intestine has a large number of finger-like projections called villi. These villi provide a large surface area for absorption of food.
Explanation:
Hope this helps!
Have a good day or night!
➜ The small intestine is the main region for the absorption of digested food. The inner lining of small intestine has millions of tiny finger-like projections called villi. The presence of villi gives the inner walls of the small intestine a very large surface area for absorption of digested food. The villi are richly supplied with blood vessels which take the absorbed food to each and every cell of the body.
Name some bubonic plague
Bubonic plague is one of three types of plague caused by the plague bacterium (Yersinia pestis). One to seven days after exposure to the bacteria, flu-like symptoms develop. These symptoms include fever, headaches, and vomiting. Swollen and painful lymph nodes occur in the area closest to where the bacteria entered the skin. Occasionally, the swollen lymph nodes, known as "buboes".
Answer:Today, it's best known as the Black Death or the bubonic plague. Medieval people called it "the blue sickness," La pest ("the Pestilence"), and "the Great Mortality." The name bubonic comes from the medieval Latin word bubo via Italian bilbo--meaning a pustule, growth, or swelling.

Explanation:
A society uses this sustainable practice because it reduces the amount of carbon dioxide in an area. So, the correct option is (A).
What is Sustainable practice?Sustainable practices are described as supporting ecological, human and economic health and vitality. Sustainability recognizes which resources are limited. It should be used conservatively and wisely which take into account long-term priorities and consequences of the way resources are used.
Reduce, reuse and recycle are the basic principles of wise use of resource. Natural resources are conserved and protected by deploying these principals by reducing landfill waste, energy consumption and pollution.
Some sustainable practices are:

when a cell goes through mitosis and cell division, the two new cells have _?
Answer:
D. Same number of chromosomes as the original cell
Explanation:
Mitosis is a kind of cell division which results in two daughter cells that are genetically identical to one another and the parent cell. Mitotic division causes each daughter cell to contain the SAME NUMBER OF CHROMOSOMES as the parent cell.
For example, a somatic human cell contains 23 pairs of chromosomes. If this cell undergoes division by mitosis, the two daughter cells that will result will contain 23 pairs of chromosomes each. This means that the two new cells that results from mitosis have the same number of chromosomes as the original cell.
Define the word. Next use the word in a sentence.

A massive farm near our school has recently had a
decrease in crop production (e.g., not as many plants are
successfully growing). A soil ecologist was notified. She
immediately noticed that there were no worms, bacteria, or
other microorganisms in the soil, even though she knew that
many organisms were present in the soil five years ago. Based
on this information, she would probably say that the population
density of microorganisms had
a. Increased
b. Decreased
c. Immigrated
d. None of the above
Answer:
C. Immigrated
Explanation:
The plants stopped growing, so I imagine the microorganisms moved to find a better food source.

Estimate the electric field in the membrane wall of a living cell. Assume the wall is 14 nmnm thick and has a potential of 0.11 VV across it.
Answer:
The electric field in the membrane wall of a living cell is 7.857 x 10⁶ V/m.
Explanation:
Given;
thickness of the membrane wall, d = 14 nm = 14 x 10⁻⁹ m
potential of the membrane wall, V = 0.11 V
The electric field in the membrane wall of a living cell is calculated as;
[tex]E = \frac{V}{d} \\\\E = \frac{0.11}{14 \times 10^{-9}} \\\\E = 7.857 \times 10^6 \ V/m[/tex]
Therefore, the electric field in the membrane wall of a living cell is 7.857 x 10⁶ V/m.
Starting with spore dispersal, and identify adaptations in the life cycle of the bryophyte for living in a terrestrial environment (ie, in air, without water surrounding the plant body). What are new stresses associated with living on land, and what morphological or physiological features did the first land plants have to evolve to cope with these stresses
Answer:
Stresses such as lack of nutrients, space, competition and water availability.
Explanation:
Lack of nutrients, space, competition and water availability are the stresses that the bryophyte can experience by living on land. The morphological or physiological features such as lowering transpiration rate by stomata, attain specialized structures to collect sunlight and fulfill water requirement by absorbing water from the air if no water is available in the soil etc are the features that the plant has to attain to cope with these stresses.

How does the skeletal system interact with the nervous system?
A
the nervous system supplies the blood and oxygen to developing bones
B
the nervous system supplies nutrients and minerals to developing bones
C
the skeletal system controls the messages sent to the brain and spinal cord
D
the skeletal system provides protection for the brain and spinal cord
Answer:
The skeletal muscles connect to the bones and work with connective tissue at the joints to allow for movement. The muscles connect to the nervous system and allow initiation of movement through nerve signals to and from the brain. The bones and muscles are supported by connective tissue, which plays an integral role in structural support.
