To model ocean water in different places on Earth, a student pours equal amounts of water in two containers. He adds the same am

ount of salt to each container and stirs until the salt is completely dissolved. He places Container 1 in a cool place in the house and Container 2 outside in the sunlight. After two hours, he tests the salinity of water in each container. What should the student MOST LIKELY conclude, and why?

Answer:

The correct answer would be - container 2 will have less salinity than container 1.

Explanation:

The given experiment can give an idea about how the temperature of surroundings can affect the salinity, volume, and density of the water that has the same amount of water and salt dissolved in it. The independent variable or the only variable that is different is their place that has a difference in the temperature. Container 1 is placed in a cool place while container 2 is placed in sunlight.

We know that the warmer the water it takes more space so, therefore, less density. Density and salinity both have a positive relationship so an increase in density increases the salinity and vice versa. Thus, here the salinity of container 2 would be low in comparison to container 1

Which type of movement is characteristic of the articulation between the tibia and fibula with the talus?
jonny [76]

Solution:

The function and mobility of each joint depends on its anatomical design. Joints that permit no movement or slight movement are common in the axial skeleton where basic structural support and protection  is expected. Joints that are freely moveable are common in the appendicular skeleton where mobility is required. Is known as articulation.

The tibial collateral ligament reinforces the medial side of the knee joint and the fibular collateral ligament reinforces the lateral side of the knee joint. Two popliteal ligaments reinforce the posterior side of the knee joint.

svp [43]

Answer: They are sterile

Explanation:

Mule is a hybrid of male donkey and female horse with different chromosome number and is considered superior to both horse and donkey. Still it is considered as a weak hybrid this is because the mule is sterile which means that it cannot reproduce further.

The mule though is superior in many ways such as it can jump and is strong. The hybrid of mule is not good as it cannot continue its next generations on earth.

They are sterile and so is a weak hybrid.

Setler [38]
Experimentation (or the experiments the scientist was doing for 10 years) could be wrong or done in an inappropriate way. The only way to know if the information is valid is by checking the way the experimentation (data) was done as well as making sure to check all other factors
