A plane travels 2500 miles in 180 seconds. What was its speed?
Answer:
speed = 22352 m/s
Explanation:
Given data:
Distance travelled = 2500 miles (2500 mile×1609 m /1 mile = 4023360 m)
Time taken = 180 sec
Speed of plane = ?
Solution:
Formula:
s = d/t
s = speed
d = distance
t = time
by putting values,
s = 4023360 m / 180 sec

Question 2: Symbiosis Symbiosis is another type of two-species interaction. It literally means living together, and refers to pairs of species that live in close physical proximity with the other species for a major part of their life cycles. Some examples of symbiosis: You and the microorganisms that live in your intestines; bark beetles burrowing in pine tree trunks; Monarch butterfly caterpillars and milkweed plants; and algae living in coral tissues. Can you think of any symbiotic interactions that are commensal or parasitic
Answer:
Commensal= mites and larger insecta who fly. Hermit crabs and shells of other organisms. Remora fish and whales. tree frogs and plants.
Parasitic= tick and dogs, tapeworm in humans, Barnacles and whales
Explanation:
Commensalism is when one species benefits and the other is neither helped or harmed. Parasitism is when one benefits and the other is harmed.
Which of the following is the focus of the NOAA?
limiting fishing
preserving fish species
policing fishing methods
maintaining water quality
Answer:
preserving fish species
Explanation:
"NOAA" stands for "National Oceanic and Atmospheric Administration." It focuses on preserving the marine environment and shares information about the climate, weather and so on. This means that its focus is to "preserve the fish species," and in order to do this, it created policies like the "Annual Catch Limits." This will prevent overfishing and ensure the world of a sustainable fish supply. Besides this, they also try to improve fish habitats and ensure the water quality in order for fishes to thrive.

A group of lions is chasing a zebra. The lions are most likely responding to which kind of stimulus?
the external stimulus of fear
the internal stimulus of fear
the external stimulus of hunger
the internal stimulus of hunger
Answer:
internal stimulus of hunger
Explanation:
Lions do not fear externally or internally of the zebra because they eat the zebra once they kill it and they are chasing after it so no fear what so ever.
Lions are naturally lazy and hunger is normally why they would be hunting because they need food to survive, however this is not always the case.
there have been a pair of documented pair of male lions known as the Tsavo Man-Eaters, who hunted for sport. Their den contained animal and man bones.
they actually made a movie about it, If you want to watch the movie just look up Ghost in the Darkness. You can actually see the lions in the Field Museum of Natural History in Chicago, Illinois.

A field biologist observed and recorded the ground squirrel population in a forest ecosystem over a 40 year period. During which
years is the squirrel's ecosystem most stable?
A)
years 1-9
B)
years 10-30
years 31-37
D)
years 38-42
Years 10-30 covers a longer time period and thus might provide a better representation of the ecosystem's stability over time. The correct option is B.
What is ecosystem?An ecosystem is made up of all the organisms and the physical environment in which they live. These biotic and abiotic elements are linked by nutrient cycles and energy flows.
If the ground squirrel population is assumed to be relatively stable over time, the years with the least amount of change or variation in population size would indicate the most stable ecosystem.
Forest, desert, rain forest, grassland, tundra, savanna, and mountain ecosystems are the most common types of ecosystems.
Healthy ecosystems clean our water, purify our air, keep our soil in good condition, regulate the climate, recycle nutrients, and provide us with food.
They supply raw materials and resources for pharmaceuticals and other uses.
Thus, the correct option is B.

What goes into a cell during Cellular respiration? Give me a simple answer, I'm in 6th grade!
Answer:
Oxygen and glucose.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
Hence, oxygen and glucose goes into a cell during Cellular respiration and as such are known as the reactants.

which 2 processes are directly responsible for the growth and development of a butterfly?
Answer:
development, growth and reproduction that a living thing goes through.
Explanation:
A life cycle refers to the stages of development, growth and reproduction that a living thing goes through. Every butterfly goes through four stages of development: (1) egg, (2) larva, (3) pupa and (4) adult. This process of development is called metamorphosis.
The two processes that are directly responsible for the growth and development of a butterfly are metamorphosis and molting.
What is Metamorphosis process?Metamorphosis is the process by which a butterfly develops from an egg to a larva (caterpillar), then to a pupa (chrysalis), and finally to an adult butterfly. During this process, the butterfly undergoes significant changes in its body structure, behavior, and diet.
Molting is the shedding of the outer layer of skin (cuticle) that allows the butterfly to grow and develop. The caterpillar undergoes several molts as it grows, shedding its skin and developing a new, larger one.
Each molt allows the caterpillar to increase in size and change in appearance as it progresses through its developmental stages.

Next, several biochemical tests are run to further identify the microorganism. Lactose fermentation is run for 24 hours at 37⁰C in lactose broth containing a Durham tube and phenol red indicator. The result shows a red broth with no air bubbles in the Durham tube.
What do these results mean in terms of this microorganism’s ability to ferment lactose?
Answer:
The organism is not a lactose fermenter.
Explanation:
The result means that the microorganism was not able to ferment lactose.
The lactose fermentation test is conducted to test the ability of a bacterium to utilize the carbohydrate, lactose, as its carbon source. A bacterium that is positive for this test would be able to ferment lactose to produce lactic acid.
In order to conduct the test, a pure culture of the microorganism is inoculated in phenol red lactose brought and incubated at the optimum temperature for about 24 hours. If the organism is able to ferment lactose, lactic acid and carbon dioxide gas would be produced. This means that the phenol red indicator would color to yellow from red and the Durham tube would contain air bubbles.
In this case, there was no change in color of the indicator nor production of gas in the Durham tube. Hence, the microorganism is concluded to be a non-lactose fermenting one.
