C. Two different species of birds

D. Two different species of

Answers
Two different species of mammals competing for the same water source is an example of two organisms competing for an abiotic factor.
What is abiotic factor?
Abiotic factors refers to non-living physical parts of the environment that affect living organisms as well as the functioning of ecosystems. In the above example, water source is a non-living part of an ecosystem which is required by both organisms.
This leads to competition of two mammals so we can conclude that two different species of mammals competing for the same water source is an example of two organisms competing for an abiotic factor.

A Class-A 10 mL pipette is supposed to dispense 10.00 mL of water. A lab technician makes three measurements of the volume that the pipette actually dispenses, and obtains volumes of 9.70 mL, 9.69 mL, and 9.71 mL. The pipette is:__________
a) Accurate, but not precise
b) Precise, but not accurate
c) Accurate and precise
d) Neither accurate or precise
Answers
Answer:
d) Neither accurate or precise
Explanation:
Accuracy and precision are critical factors in the experimental procedure. Accuracy can be defined as the amount of uncertainty in the process of measurement in relation to the true value (in this case, 10 mL). On the other hand, precision is an independent feature of the accuracy which indicates the repeatability of the measurement process (in this case, three measures weren't repeated). Therefore, precision indicates the confidence of a particular measurement, while accuracy indicates how close is this value to the real value.

Wolves that live in snowy climates often prey on rabbits. Some rabbits can move quickly across deep snow because they have large feet that don’t sink into the snow. Rabbits without this adaptation move more slowly across the snow. Which statement best justifies how the rabbit population changes over time?
A. Sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment.
B. The ocean water would change its current so that the acidic water is relocated to another area and allow sea coral to survive.
C. The ocean water would change its composition to reduce the amount of carbon dioxide contained and allow sea coral to survive.
D. Sea coral would become extinct because of its inability to make adaptations fast enough to adjust to the changes in the environment
Answers
Answer:
It's A
Explanation:
Just like the corals have genetic mutations to adapt to their environment so do the rabbits change their genetic characteristics to make sure the species continue it's lineage by evolving and growing their feet so they can be faster and not sink in the snow, becoming harder preys to catch, otherwise, if their paws were smaller, they would be slower and, therefor, an easy catch for the wolves, probably becoming extinct after awhile.
The statement that justifies how the rabbit population changes over time is sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment. So, the correct option is A.
What is Adaptation?Adaptation is the process by which a species becomes fitted to its environment; it is the result of natural selection's acting upon heritable changes.
Rabbits have to change their genetic characteristics same as the coral have genetic mutations to adapt to their environment and to make sure the species continue its downstream by evolving and growing their feet, so they can run faster in the snow and successfully escape from predators. If rabbits are not evolved with an environment that does not favor them, they are surely eliminated from nature.
Therefore, the statement that justifies how the rabbit population changes over time are sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment.

5. A student is studying how sound travels
through a solid medium by timing
the movement of sound through a
boulder when the boulder is at different
temperatures. Using the information above,
how fast will sound move through the
boulder when it reaches 20°C?
Answers
Answer:
570 m/s
Explanation:
The speed of sound is a measure of how fast sound travels through a medium. The speed of sound through various media varies. Sound travels fastest through solids and slowest through gases for example air.
The temperature of a medium affects the speed of sound through that medium. The higher the temperature, the faster sound travels through the medium. This is because, as the temperature of the medium increases, the particles of the medium vibrates faster and faster, thus sound waves are able to be propagated faster through that medium.
From the information provided in the attachment, the speed of sound through the boulder increase by 2 m/s for every 5°C rise in temperature. Therefore, the speed of sound through the boulder when it reaches 20°C will be 570 m/s

John Terborgh, tropical ecologist at Duke University, asserts that in order to save tropical forests, citizens of industrial nations are going to have to pay developing countries. Do you agree
Answers
Answer:
I do agree
Explanation:
As a personal opinion, I do agree with this statement. Citizens of developing countries use these rain forests for many reasons. One of which is for survival they cut down and use what they need in order to gather the resources that they need and build their habitats. This goes slowly destroying the rainforests. The other reason is that these citizens many times sell the rights to the rainforest land to mining companies that ultimately destroy the rainforest for its resources. The only way to prevent both of these from happening is by paying these developing countries to protect the rainforest instead of profiting from it.

Propose an explanation for why humans have experienced exponential growth since the Industrial Revolution? (why was our population able to live longer and reproduce more successfully). What do we have access to now that was nonexistent or difficult to access in the past?
Answers
Answer:
The Industrial revolution increased chances of survival for human due to technology and increased ways to get food
Explanation:
The human population of the planet increased gradually for more than 10,000 years after the Agricultural Revolution. As the population continues to grow, competition for resources will increase. Natural disasters and political conflicts will exacerbate the problems, especially in the more stressed regions of developing nations. The survivors of this competition will likely be determined by factors such as place of birth and educational opportunities.

Explain why countercurrent flow met the goals and why parallel flow did not meet the goals.
Answers
Answer:
Countercurrent flow met the goals due to difference in concentration gradient.
Explanation:
Countercurrent flow met the goals because it flows in opposite direction while on the other hand, parallel flow did not meet the goals because it flows in the same direction. For example. the blood flows in one direction and the dialysate flows in the opposite direction. The countercurrent flow of the blood and dialysate increases the concentration gradient between the blood and dialysate. The increased gradient helps to remove more potassium, phosphorus and urea from the blood. If we used parallel flow so less concentration gradient of solutes is present and hence, less potassium, phosphorus and urea are removed from the blood
In fluid or a flowing body when there is interexchange or a crossover of some fluids with each other is called countercurrent flow while when the fluid flows in the same direction then it is called parallel flow.
Countercurrent meets goals because of concentration gradient differences.
Countercurrent and parallel flow can be explained as:The goals are met in countercurrent because of the opposite direction while in parallel they are not achieved because of the same direction.Countercurrent flow in fishes helps them to increase the blood oxygen level from water as this system help them efficiently maximize the oxygen needed for respiration.If the parallel flow is used then the concentration gradient would be less and hence less oxygen will be available from the water to fishes.Therefore, countercurrent achieves its goal while parallel dies not.
