Study the graph below. At what depth does the thermocline begin?
A line graph relating ocean depth to water temperature. At 0 meters, temperature is approximately 27°C. At 100 meters, temperature is approximately 24°C. At 200 meters, temperature is approximately 11°C. At 300 meters, temperature is approximately 8°C.

0 meters
100 meters
200 meters
300 meters
Answer: 100 meters
Explanation:
The thermocline begins at 100 meters of depth. Thermocline is a transition oceanic water layer between deep and surface water in which water temperature decreases rapidly with increasing depth. From the given graph it cam be seen that at 100 meters the thermocline begins such that the temperature drops from to.

Athletes train at high altitude, thereby increasing the number of red blood cells, to improve their
performance. How might an increase in the number of red blood cells improve an athletes
performance?
Answer:
Preparing at moderate height may improve ocean level execution in perseverance competitors. This was noted after the 1968 Olympics in Mexico City (7600 feet) when a few competitors found an improvement in their presentation after re-visitation of ocean level. Be that as it may, different competitors didn't see any distinction in execution. Studies have indicated improved high-impact power in sprinters who prepared at 6,000 feet for 10 days at that point performed at low elevation. Lower oxygen levels at elevation invigorate EPO prompting expanded red platelets or hematocrit. This viably permits more oxygen to be conveyed to the tissues. Basically, this is blood doping the regular way.
Late examinations do propose profits by 'preparing low' and 'dozing high'. This incorporates hypoxic tents that numerous competitors are presently utilizing. These tents have a generator that extricates oxygen from the air, establishing a moderate height climate. Competitors at that point rest/relax in them for a few hours per day. This invigorates erythropoietin, subsequently expanding the hematocrit (red platelet tally). Without a doubt the 'live high, train low' idea may permit the best blend. One examination separated 39 contenders into three preparing gatherings; living and preparing adrift level, living at height and preparing adrift level, living at elevation and preparing at height. The two gatherings who inhabited height had expanded red platelets and VO2max, however just the gathering who lived high and prepared adrift level had improved race times. One clarification for this is that the live high, train low gathering can prepare more diligently and better use their blood's oxygen conveying limit. As a result of expanded red cell creation, all competitors preparing as well as resting at elevation should ensure they have proper iron stores and nourishment. This is particularly valid for ladies, as they will in general have lower iron stores because of occasional loss of blood through monthly cycle.

Newton's third law of motion states that whenever a first object exerts a force on a second object, the first object experiences a force equal in magnitude but opposite in direction to the force that it exerts
Question 5 options:
True
False
I need help from someone who's actually helpful and smart please
Answer:
true
Explanation:
i took the test
The statement "Newton's third law of motion states that whenever a first object exerts a force on a second object. The first object experiences a force equal in magnitude but opposite in direction to the force that it exerts" is true.
What is Newton's third law?
His third law argues that there is an equal and opposite reaction to every action (force) in nature. When object A pulls on item B, object B pulls back on object A with an equal and opposing force. In other words, interactions lead to forces.
According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.
Therefore, the statement is true.

A classmate explains that igneous rocks can be changed to metamorphic rock by first being melted into magma and then cooling. What correction needs to be made to this statement?
Answer:
Cooled magma becomes igneous rock
Explanation:
Took the quiz
Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.
What are rocks?There are three different types of rocks: metamorphic, sedimentary, and igneous. These rocks can all alter. In actuality, any rock may transform into any other kind of rock.
Condensation and cooling: The Earth's interior can experience temperatures hot enough to produce magma. Igneous rock is created as crystals develop in the cooling magma.
If the lava cools gradually, as it does if it stays inside the Earth for an extended period, the crystals enlarge. The crystals will be very tiny if the magma cools quickly. Crystallization is the process by which crystals emerge from magma.
Therefore, Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.

In Gregor Mendel's study with the color or peas, which ones were dominant and which ones were recessive?
Answer:
The peas with the purple flowers were dominant and the peas with the white flowers were recessive.
Explanation:
In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers. The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant. The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple. The flowers were only white if both alleles were for white flowers.
