Which feature separates watersheds?
A.) basins
B.)bays
C.)ridges
D. )rivers
Answers
Answer:
c
Explanation:
C.) Ridges are the feature that separates watersheds.
What is watershed ?A watershed is a region or area of land that collects and drains water into a particular river, stream, or other body of water.
Ridges or high points of land are critical in separating watersheds because they provide the boundary or border between two adjacent watersheds. When rain falls or snow melts, the water will flow downhill towards the closest body of water.
However, if that body of water is separated from another by a ridge, the water will flow down opposite sides of the ridge, into different watersheds.
Ridges are created by geologic processes such as tectonic uplift or erosion, and can vary in size and height. In some cases, a single ridge can divide a large drainage basin into two or more smaller ones, each with its own unique set of characteristics and ecosystems.
The boundary or border of a watershed is formed by a ridge or high point of land that separates one watershed from another. Water that falls on one side of the ridge flows into one watershed, while water that falls on the other side of the ridge flows into a different watershed.

what would happen if a new predator was introduced into the ecosystem that only ate mice ?
Answers
Answer:
The ecosystem would drastically change.
Explanation:
Here is a food chain that involves mice:
Sunlight -> Berries -> Mice -> Snake -> Bald Eagles
So, let's say a new animal was introduced, and it eats mice. There would be more berries, as the mice wasnt eating them, the snakes would start to starve as there is not as many mice, and the bald eagles may start to starve as no more snakes for them to eat!
I hope you understand, and have a wonderful day!
He may not know to use ecosystem in overcoming his hunger , he may end up.starving and at last he would choose to eat plants and he will adapt with the nature of ecosystem .
In second case ,
he may get disturbed / fruatated and destroy the whole ecosystem .
in third case ,
he may not know how to use the ecosytem and die not eating anything .
So , if overall we see , our animal may die in two cases . the only case how an meat eating animal will survive in new environment is by adapting himself , but is he could not then he will die . so living - dying ratio is 1:2 . so we can predict that the animal will not survive . But as we know animals are not like new era humans and dont have tantrums like em' , so they will adapt . but adaptations take a lot time , before that the animal dies because of aging then nothing can be done .
Infact , this is how humans has evolved from a monkey to a social animal . we all know that humans have been fast devaloping animal and thats what we are today , but there was no one to force human to evolve as a whole im trying say there was no disturbance because of any other species in case of human .
so because of disturbance that animal may or may not adapt .
the answer is depends .

PLEASE HELP! THIS IS AN EASY EXPERIMENT BUT I DONT HAVE A PARTNER. PLEASE HELP ILL GIVE YOU 50 POINT!!!! IT won't TAKE YOU MORE THAN 10 MINUTES TO DO THIS
Instructions
1. Find a partner to complete the experiment with you. Do not do this experiment if you or your partner has a heart condition or other medical problem.
2. Take your heart rate by placing your middle or index finger on your wrist just below the thumb. Be sure to feel a distinct pulse before you proceed further.
3. Count the number of beats in 15 seconds and multiply this number by four to get the number of beats in one minute. This is your resting heart rate.
4. Record your resting heart rate in the table.
5. You should run or jump in place for 1 minute. When completed, have your partner take your pulse and record it in the table.
6. Keep track of the time and take your pulse at 1-minute intervals after you completed the initial exercise and record these results in the table.
resting heart rate:
heart rate directly after exercise:
heart rate 1 minute after exercise:
heart rate 2 minutes after exercise:
heart rate 3 minutes after exercise:
5. Have your partner complete steps two through six. Your partner should record their results below:

heart rate 2 minutes after exercise:
heart rate 3 minutes after exercise:
Write a summary statement on what your results were and why? Include in your summary differences between you and your partner, your ages, your genders, your physical condition, or anything that you feel would have a bearing on your heart rate. Also, include in your summary the answer to this question: How do you think your results would change if you were 30 years older, and why?
Answers
Answer:
I did the exercise for you, and most of the summary.
Explanation:
My results were 64bpm before exercise, 96bpm directly after exercise, 76bpm 1 minute after exercise, 68bpm 2 minutes after exercise, and 64bpm 3 minutes after exercise. This is because I exercise often, which improves my cardiovascular function/fitness.
I am 19, female, and moderately fit.
Resting heart rate: 64bpm
heart rate directly after exercise: 96bpm (24x4=96)
heart rate 1 minute after exercise: 76 bpm (19x4=76)
heart rate 2 minutes after exercise: 68bpm (17x4=68)
heart rate 3 minutes after exercise: 64bpm (16x4=64)

(B) No
Explanation:
Producers, primary consumers and secondary consumers which form part of an ecosystem perform cellular respiration.
What is cellular respiration?It is a set of reactions by which certain organic compounds are degraded by oxidation, until they become inorganic substances and energy that can be used by the cell.
Most living organisms that are part of an ecosystem carry out cellular respiration, in plants, animals, fungi and protozoa it is carried out in the mitochondria and the cytoplasm.
Therefore, we can conclude that producers, primary consumers and secondary consumers which form part of an ecosystem perform cellular respiration.

The diagram below shows the Moon's orbit around Earth. Letters A, B, C, and D represent four positions in the Moon's orbit.
What is the approximate length of time it takes the Moon to travel from position A to position C?
1 day
14 days
28 days
31 days
Answers
Answer:
14 days is the correct answer. Since it takes 27(approx) days to complete one revolution of the earth and will take (27/2=14) days to complete half of the revolution I.e. A to C.
The orbit of the Moon around Earth is shown in the diagram below. Four locations in the Moon's orbit are represented by the letters A, B, C, and D.
How long does it typically take the Moon to move from position A to position C?
The Moon takes 28 days to go from location A to position C, which is a rough estimate. The Moon is at perigee, or its closest point to Earth, at position A. The Moon is at its apogee, or furthest point from Earth, at location C. Even though the Moon's orbital speed varies, it does take about 28 days to go from perigee to apogee. The Earth's orbit around the Sun and the Moon's orbit are both inclined.
This indicates a tilt between the orbital planes of the Earth and the Moon. The Moon's location with relation to the Sun consequently shifts throughout time. The Moon appears to "wax" and "wane" in the night sky because of this. The 28-day synodic period of the Moon accounts for the Moon's shifting positions with respect to the Sun.
Therefore, it may be concluded that it takes the Moon 28 days to roughly travel from place A to position C. This is due to the Moon's relatively slow orbital motion, which takes around 28 days to complete from perigee to apogee and from one place in relation to the Sun to another.

The exhaust system of the car is the excretory system that removes waste.The engine of the car is the digestive system that circulates nutrients to the rest of the body.Thus, the correct options are C and D.
What is Analogy?An Analogy may be defined as the condition of comparing two things in order to reveal the identical function of each other. It makes the process of understanding more clear and effective.
The engine of the car is analogous to the digestive of the human. This is because it provides the energy for other parts to function properly.
The exhaust system of the car is analogous to the excretory system of the human. This is because it removes all the waste material out of the car in the form of smoke, dust, etc.
